Voltage stabilizer for the refrigerator: how to choose the right protection

What kind of voltage stabilizer is needed for a refrigerator

There are several key points to consider when choosing a refrigerator stabilizer and I will describe them all below.

1. The voltage stabilizer for any household refrigerator must be single-phase, 220V

The vast majority of household refrigerators, regardless of the number of chambers, sizes, functions, etc. - single-phase and operate from a voltage of 220V. They are connected to a standard household outlet, respectively, and a voltage regulator for them needs a similar one - single-phase.

2. What type is better to choose a stabilizer for the refrigerator

Currently, there are many varieties of voltage stabilizers. All of them are based on different operating principles and components. They differ in response speed, control range, degree of protection, and in a number of other characteristics.

Of course, it is always easier to recommend the most modern and perfect models, which will most likely stabilize the voltage and maintain the operation of the refrigerator in a wide range of input voltage. But let's be realistic, for many, simplicity, reliability, maintainability and, most importantly, its cost are more important in a stabilizer.

At present, the most effective solution, specifically for the refrigerator, will be a conventional relay stabilizer. The basis of which is an autotransformer with several taps with varying degrees of transformation.

Usually, if my clients ask me what kind of voltage stabilizer they should buy for a refrigerator, I advise you to choose an inexpensive, but already beloved by many RESANTA ACH-2000 or its analogues, which are always available in the most popular electrical equipment stores and there are no problems with the purchase and service.

At the same time, for only 2000-2500 rubles you get a fairly reliable and fast voltage stabilizer with a power of 2 kVA (Produces 2 kW of active power), usually this is enough to keep your refrigerator working smoothly even with fairly strong voltage drops.

3. What should be the power of the voltage stabilizer for the refrigerator

The power of the voltage regulator is a value that shows what maximum load this device can supply.

At the same time, it is important to remember that most of the especially inexpensive models of stabilizers have a direct dependence on the drop in output power depending on the input voltage in the network.

In simple words, if, for example, your voltage in the outlet drops to 190V, then a 1000 VA stabilizer will hold all 100% of the declared load, but as soon as the voltage drops below, for example, to 150V, then the maximum possible load will drop , usually somewhere around 40% and will be only 600 VA.

Let's look at how to consider all these factors when choosing a voltage regulator.

So, when calculating the power of the stabilizer, you need to know two main quantities:

- Starting current or refrigerator compressor power

— Minimum and maximum voltage in the network

Calculation of the power of the stabilizer for the refrigerator

The most important parameter is the power of the stabilizer. It is specified in VA (volt-amperes) and implies the total output power at a voltage of 220V. Refrigerator power consumption indicated in the passport data and expressed as active power in watts. It is advisable to focus on the full power in VA.

To get this data, you need to divide the indicated values ​​\u200b\u200bin watts by a factor of 0.65, as a result we get the total power of the refrigerator. Since the refrigerator contains an electric motor in the compressor, when it is started, large starting currents occur, therefore, the total power must be increased by three times.
Next, the ratio of the total power of the refrigerator is taken, taking into account the starting currents, and the power that the stabilizer can produce at the minimum allowable input voltage. For example, a refrigerator consumes 300W. The total power is calculated taking into account the starting currents - 250/0.65∙3=1154 VA. This means that a stabilizer is needed, which, at a minimum voltage, will have an output of 1200 watts.

Knowing the current consumption of the transformer, you can find out the power at this voltage.

Voltage stabilizers 220V for refrigerators have the ability to be connected separately, that is, they have a plug and an output socket; when used, they must be placed away from heat sources and periodically cleaned of dust.

Why do you need a voltage stabilizer for the refrigerator?

A domestic refrigerator is powered by electricity and includes parts such as an electric motor, compressor, relay protection, and an electronic control board. These elements are designed for a certain voltage and current, and if the indicators deviate from the permissible values, various malfunctions occur. There are several main reasons that can lead to equipment failure.

undervoltage

When the voltage is not enough to start the engine, the compressor does not start, but the current passes through the winding, heating the wire. If this happens for a long time and often, then the engine may fail.Dangerously low voltage even when the compressor is running. In this case, to provide the required power, the current automatically increases, and this leads to heating of the metal, and then damage to the insulation.

overvoltage

An increase in this indicator leads to an increase in power, which causes the engine to work with overload. With a long period of this mode, it fails.

High voltage interference or power surges

The instability of the electrical network is caused by various objective and subjective reasons. Almost no network can be insured against short-term fluctuations in its main indicators. One of the most dangerous options is a sharp voltage surge, while its value can increase several times for a short time, which is enough to breakdown the insulation of the motor winding. Even in cases where the voltage is not enough to breakdown the insulation, a frequent drop in its values ​​\u200b\u200bleads to the failure of electronics, which are quite sensitive to such fluctuations.

When is refrigerator protection necessary? To find out, it is necessary to clarify the quality of the supplied electricity. To do this, for a certain time, you should periodically measure the voltage in the outlet using a tester (voltmeter). This indicator should be compared with the permissible values ​​\u200b\u200bspecified in the instructions for the equipment.

Recommendations for the installation of stabilizers are given by GOST 32144-2014 (clause 4.2.2). Critical for a refrigerator is an increase in voltage by more than 10% and a decrease in it by more than 15%.

In other words, an ideal network that does not require precautions can be considered a network in which the voltage never goes beyond 190-240 V.In such conditions, household appliances do not require additional protection. In modern refrigerators, a built-in stabilizing device is often installed.

However, practice shows that it does not work reliably enough with significant voltage fluctuations. In unstable networks, there is a high probability of failure of such devices, and therefore it is better to install an additional, reliable device

Choosing a voltage stabilizer for the refrigerator

Purchase is the completion of the selection process. Before it, you need to do several actions that will help you buy the device that will be needed specifically for your unit.

According to the types of electrical networks are divided into:

• single-phase (220 volts);
• three-phase (380 volts).

Depending on the type of network, you need to choose a single-phase or three-phase stabilizer.

Single-phase and three-phase stabilizer

In addition, according to the types of network voltage, there are:

• with low voltage;
• with high;
• with jump.

In the first case, the device will raise the indicators to the desired level, in the second it will lower it, and in the third it will equalize, protecting it from drops.

Having learned these parameters in her housing maintenance company or in a company supplying electricity, the hostess will be able to choose a voltage stabilizer specifically for her apartment or country house.

The store can offer a choice of several types of stabilizers:

• relay;
• electromechanical (servo);
• electronic.

Electromechanical, electronic and relay stabilizers

The first type is the simplest in the device (and therefore inexpensive). It is resistant to overloads, has a simple control system and satisfies the needs of modern refrigerators.

The second type smoothly regulates drops, maintains accurate voltage readings, and is inexpensive. But with strong surges in the network, the mechanical parts of the device can break down, so for summer cottages and private houses, where welding machines and other equipment are often turned on, it is better not to buy these.

Electronic stabilizers are the pinnacle of evolution (which is why they are much more expensive than their counterparts). Devices instantly equalize network performance, operate silently, withstand high and prolonged overloads:

• up to 100% voltage for 1 minute;
• up to 20% voltage for 12 hours.

The principle of operation of stabilizers

In all electrical networks, a truly stable voltage exists only in theory. In fact, its parameters are subject to constant changes. Such situations often arise due to consumers connected to the network and giving impetus to a decrease in voltage. In most cases, such deviations do not exceed 10%, however, modern electronic devices react extremely negatively even to small changes. To avoid such situations, stabilizing devices are used together with electrical equipment.

The main structural element of the stabilizer is a transformer. It is connected via a diode bridge to the AC circuit. The circuit is complemented by a transistor and capacitors. The regulator is also installed here.Automatic switching on and off is carried out using a locking mechanism.
Each stabilizer must function on the basis of feedback, working according to a certain scheme. The voltage is initially applied to the transformer. If its standard value is exceeded, a diode or diode bridge comes into action, connected directly to the transistor in a common circuit. Due to this, additional voltage filtering is carried out, and the capacitor acts as a kind of converter. After passing the current through the resistor, it again returns to the transformer, which leads to a change in the nominal value of the load and power.

Thanks to automation, all processes performed in the network are stable, and the capacitors are not subject to overheating. At the output, another filter is used to pass the mains current, after which the voltage is finally rectified and becomes usable.

Selection Tips

First of all, you should decide what kind of voltage equalization device you need: single-phase or three-phase. As a rule, the household network is single-phase. But there are exceptions. If there is no exact information, it is worth checking with the electrician servicing the network.

Devices are produced by different manufacturers, both domestic and foreign. At the same time, even in the Russian market there are several worthy firms. For example, the products of Energia or Resanta are very popular.

For the safe operation of the refrigerator, 3 types of stabilizers are suitable: relay, electronic-mechanical and triac. Let's take a closer look at the benefits and cons of each type.

Relay transformers

relay stabilizer

In relay stabilizers, as the name suggests, the transformer windings are switched using power relays. In the figure we see the simplest circuit of a relay stabilizer built on the basis of comparators. A comparator is a kind of logic circuit that accepts 2 analog signals at its inputs: if the signal at the “+” input is greater than at the “-” input, it outputs a high level signal (one relay is triggered), if the signal at the “+” input is less than at the "-" input, the comparator generates a low level signal. Thus, the transformer windings are switched.

Schematic diagram of the relay stabilizer

The advantages of relay stabilizers are:

• fast response (0.5 seconds);
• low cost;
• wide limits of increased / reduced voltages.

Among the shortcomings, we note the noise of operation (due to relay switching clicks), the possibility of burning contacts (if the voltage in the network constantly jumps).

Stabilizers of electronic-mechanical type

Electronic-mechanical representatives have a control board. It controls the characteristics of the voltage and controls the operation of the servomotor that drives the current. the receiver, which, in turn, moves along the turns of the coil, thereby controlling the work at the input.

Electromechanical Voltage Stabilizer

Let's take a schematic diagram as an example. Here, the output signals from the comparator are the inputs of RS-flip-flops built on AND-NOT logic chips. This made it possible to achieve higher accuracy (2–4%, while in relay types the error reached 8%). The disadvantages of products include low speed.

Triac

Triac voltage stabilizer

Triac stabilizers switch windings using triacs. Oxidation of contacts and clicking sounds are excluded here, which is good news. To date, triac stabilizers are the most reliable and durable, they have low errors (no more than 3%).

Simplified circuit diagram of a triac stabilizer

If the voltage fluctuates frequently, this is the best option to protect the refrigerator. The only drawback of devices of this type: the high price, compared with relay and electromechanical types of stabilizers.

Power stabilizer selection

Power is the main characteristic of the stabilizer, according to which it is chosen. It is quite clear that the power of the stabilizer should be slightly greater than the total power of all consumers. Thus, before choosing a voltage stabilizer, you need to correctly determine the total power consumption of the devices to be protected.

It should be borne in mind that the power consumption is divided into active and reactive, which make up the total power consumption of the device. Typically, devices indicate active power consumption (in watts, W), but depending on the type of load, reactive power should also be taken into account. Thus, when calculating the power of the stabilizer, you must take into account the total power consumption, which is measured in volt-amperes (VA).

• S is the total power, VA;
• P is active power, W;
• Q is reactive power, VAr.

The active load is directly converted into other types of energy - light or heat. Heaters, irons, and incandescent lamps are examples of devices with a purely resistive load.Moreover, if the device has a power consumption of 1 kW, then a 1 kVA stabilizer is enough to protect it.

Reactive loading occurs in devices with electric motors, as well as in various electronic devices. In devices with rotating elements, they speak of an inductive load, and in electronics, a capacitive load.

On such devices, in addition to the consumed active power in watts, one more parameter is usually indicated - the coefficient cos (φ). With it, you can easily calculate the total power consumption.

To do this, the active power must be divided by cos(φ). For example, an electric drill with an active power of 700 W and a cos(φ) of 0.75 has a total power consumption of 933 VA. On some devices, the coefficient cos (φ) is not indicated. For an approximate calculation, it can be taken equal to 0.7.

When choosing a stabilizer, it is important to take into account the fact that for some devices the starting current is several times higher than the rated current. An example of such devices can be devices with asynchronous motors - refrigerators and pumps. For their normal functioning, a stabilizer is needed, whose power is 2-3 times higher than the consumed

For their normal functioning, a stabilizer is needed, whose power is 2-3 times higher than consumed.

Table 1. Approximate power of electrical appliances and their power factor cos (φ)

Household electrical appliances	Power, W	cos(φ)
electric stove	1200 — 6000	1
Heater	500 — 2000	1
A vacuum cleaner	500 — 2000	0.9
Iron	1000 — 2000	1
hair dryer	600 — 2000	1
Television	100 — 400	1
Fridge	150 — 600	0.95
Microwave	700 — 2000	1
Electric kettle	1500 — 2000	1
Incandescent lamps	60 — 250	1
Fluorescent lamps	20 — 400	0.95
Boiler	1500 — 2000	1
A computer	350 — 700	0.95
Coffee maker	650 — 1500	1
Washing machine	1500 — 2500	0.9
power tool	Power, W	cos(φ)
Electric drill	400 — 1000	0.85
Bulgarian	600 — 3000	0.8
Perforator	500 — 1200	0.85
Compressor	700 — 2500	0.7
Electric motors	250 — 3000	0.7 — 0.8
Vacuum pump	1000 — 2500	0.85
Electric welding (arc)	1800 — 2500	0.3 — 0.6

In addition, the manufacturers themselves strongly recommend using stabilizers with a 20-30% power reserve.

Stabilization accuracy for optimum instrument protection

When choosing a stabilizer, you should also take into account the maximum allowable voltage drop range for the devices to be protected.

If we are talking about the protection of lighting devices, then for them it is necessary to choose a stabilizer with a voltage stabilization accuracy of at least 3%. It is this accuracy that will ensure the absence of the effect of lighting flicker, even with fairly sharp power surges in the network.

Most household electrical appliances are able to work normally with voltage fluctuations in the range of 5-7%.

What to do - put one stabilizer on all consumers, or on each separately?

Of course, ideally, for each device that needs to be protected from power surges, a separate stabilizer of the appropriate power and stabilization accuracy should be installed.

However, from the point of view of material costs, such an approach cannot be justified. Therefore, most often the stabilizer is installed on the entire set of consumers, and its power is calculated based on the total power consumption. However, another approach is also possible.

For example, any one device can be protected by a stabilizer. In addition, a group of electrical appliances can be distinguished, the protection of which from voltage surges is an urgent need, and a stabilizer is installed to power them, while the rest, which are not so important and sensitive to surges, are left without protection.

What is more important: accuracy or range?

When choosing a stabilizer, consider their advantages and disadvantages.
Is high accuracy important to you, or can it be sacrificed to operate at a lower voltage level?
If the input voltage is greatly reduced, then an electromechanical stabilizer is unlikely to suit you.
And if you need to connect high-precision equipment, then the relay model with an error of 8-10% will also be of little use.
If you choose a stabilizer for a long time, then it is better to prefer Russian-made electronic models.
And for seasonal work (for example, in the country), budget relay devices are often chosen.
For a low-power load, especially the automation of gas boilers and submersible pumps, it makes sense to install an inverter stabilizer with high accuracy
and double voltage conversion.

the manufacturer immediately warns the consumer against choosing a stabilizer at the lowest price

Which voltage stabilizer is best for a refrigerator

Do you need a stabilizer for your refrigerator, you can understand by listening to the operation of the device. If the compressor runs smoothly, smoothly starts and ends the cycle, the mains voltage is normal. Modern models have quick start protection internally, so momentary interruptions in supply may not affect the compressor. So a stabilizer is not always needed. But it is better to protect electronically controlled equipment, with displays, controlled from a smartphone, just in case.

What is the best voltage stabilizer for refrigerators, from the point of view of practitioners and specialists? In terms of price category, Chinese stabilizers are considered the most affordable, but their quality is such that manufacturers do not advertise the country of origin. It is better not to buy stabilizers up to 2000 rubles, they are produced in China only for Russia. How much damage a cheap refrigerator stabilizer can cause, and whether it is needed, is up to you.

Kinds

Devices designed to stabilize the voltage differ in design, output power and the principle of operation. According to the main features, there are three types of stabilizers:

• electromechanical type;
• relay pitchfork;
• system devices.

Some models can work from a standard and three-phase network. The first type is small due to the absence of an active cooling element; at the time of operation, they do not make noise. Three-phase equipment is connected to a 380V network, designed for heavy loads and long-term operation, but if one phase fails, the protective mode does not work.

Instruments of the electromechanical type

For a long period, only electromechanical type stabilizers were installed. Design features include the following:

• The device is controlled by an electronic board.
• The main advantage of such equipment is high accuracy. The error is only 2-4%.

The disadvantage is associated with slow response.

Similar models of stabilizers perform well with a slow change in voltage. If the jumps occur quickly and in a large range, then the equipment quickly fails.

relay type

Relay stabilizers withstand large voltage drops. The distinguishing features are as follows:

• The power relay is located on the electronic unit and the controller.
• The transition of the position is carried out within 0.5 seconds.
• The weak link in the design is the controller. It can burn out if the rated voltage is greatly exceeded.
• Comfort in the house is reduced due to the fact that when switching the mode, a clicking sound occurs.

Relay devices are used when fast voltage overload occurs constantly.

Instrument System Models

Such devices are installed more often than others. Their key features are as follows:

• Semistors are responsible for management. They work almost without delay, react to the smallest changes.
• The absence of mechanical contacts determines that there are no clicks when the device is triggered.
• Overload up to 20% is maintained by the device for 12 hours and only a minute at 100%.

Manufacturers of such equipment pay attention to the quality of the material used in the manufacture. This determines the long service life.

It is better to pay more once than to repair or buy a new refrigerator later.

Summing up all of the above, I would like to remind you that a certified product from a trusted manufacturer will save you from possible problems and equipment repairs. It is better to pay more once than to repair or buy a new refrigerator later.

We offer you to familiarize yourself with the Destruction of the smell in the refrigerator

The stabilizers selected in the tables are designed to be switched on through a socket and are provided with a cord. Models with a power of less than 2 kW are not provided with cooling fans - natural circulation is sufficient for such a device. If there is enough power, then they choose this one - there is practically no noise. In the case of low-power triac devices, extraneous sounds and buzz can only occur with poor assembly.

Consider 5 models of stabilizers of various brands and characteristics that have proven themselves from the best side:

1. LG-2500 is one of the expensive but indispensable models of stabilizers for domestic use. A power of 2.5 kW allows you to power not only the refrigerator, but also other appliances (washing machine, iron, boiler). Its price varies from 13,000 to 18,000 rubles, depending on the configuration.

2. Atlant, model Energy SNVT-1500 is a domestic unit that is ideal for use in a refrigerator. It is designed for input voltage from 100 to 280 V. It has good technical characteristics, as well as a warranty period of 2 years. The cost is more democratic, only 5000-7000 rubles.

3. Upower-ACH-1500 is the most economical model that has the same characteristics as the above analogues, but is made in a budget version. Its cost is 3000-4000 rubles.

4. Woltron PCH-1500 - used exclusively for single-phase networks. Stabilizes input power from 100 V to 280 V. Price - 4000 rubles.

Thus, the stabilizer is important and necessary not only for the refrigerator, but also for other household appliances. Its role is difficult to overestimate. The presence of a stabilizer is already a guarantee that the refrigerator will be able to work smoothly, as well as avoid breakdowns and costly repairs. It is not difficult to choose it, knowing such parameters as the total power and the phase of the network.

Conclusion

A stabilizer is a device due to which, during power surges, damage to the refrigerator, washing machine or any other electrical appliances will not be caused. It protects devices from malfunctions both at high and low voltage levels.

There are several types of stabilizers. These include devices of electromechanical, relay and system types. The first type is characterized by high accuracy, but is characterized by a rather slow speed. Relay regulators are quite fast, but somewhat noisy. System-type stabilizers are silent, accurate, but quite expensive.

To determine the peak values ​​​​of the power that is consumed by the refrigerator, you need to take the rated power indicated in the device passport, divide it by 0.65 and multiply by 3. You can add 20% up and down to the figures obtained. This will turn out the operating range in which the stabilizer should function.

When using the device, it is important to observe safety precautions. It should not touch the body of metal objects

Stabilizers must not be exposed to liquid. Otherwise, they will fail. If the device was bought only for the refrigerator, then other electrical appliances cannot be connected at the same time. Both the stabilizer itself and the devices connected to it will not withstand.

Connecting the stabilizer is very simple. Sockets are built into its body. The device also comes with a cord. The plug of the refrigerator is inserted into the socket. The stabilizer cord connects to the eclectic network.
