Surge Protection

Surge ProtectionPower surges in the mains can disable many elements of the machine. First of all, you need to take care of the main control unit, the repair of which will be expensive for the owner of the equipment. To avoid unforeseen expenses during unstable power supply, it is better to take measures in advance and protect the washing machine from power surges. We will figure out what actions should be taken as part of the upcoming work.

Will the surge protector cope?

The basic means of protecting any equipment powered by electricity is a surge protector. This element is built in at the factory when assembling the washer, directly into the unit body. With a serious jump, the filter may become unusable, but it will protect other, more expensive parts of the machine from breakage. The principle of operation of the network filter is simple: it passes only oscillations with a frequency of 50 GHz through itself, more frequent or rarer waves are blocked by the element.

Another function of the line filter is to hold and transmit back ground current waves generated during asynchronous operation to ground surge protector - a necessary element of CM protectionelectric motor. Thanks to this procedure, other components of the washing machine are relatively reliably protected from electric shock. If the washing machine did not have a surge protector, then many parts would very often be subjected to an “electric wave attack”. These are the following elements:

  • a heater;
  • asynchronous engine;
  • main control module;
  • control panels technology.

The filter element protects components not only from high fluctuations in the electrical system, but also from low ones. In the event of a component malfunction, often the washing machine is completely blocked. Using a washing machine with a malfunctioning power strip is unsafe and incorrect.

Stabilizer

No preparatory measures can 100% protect washing equipment from damage. If a power surge occurs, a happy outcome can be discussed only in 70% of cases. In the remaining 30% of situations, you will have to repair expensive household appliances.

To protect the washing and drying equipment, it is better to connect it to the network using a stabilizer.

Choose a voltage stabilizer very carefully. It is important here not to overpay the seller and at the same time ensure the safety of the washing machine. When choosing, pay special attention to the power of the unit. The indicator should be sufficient to provide the necessary power to all equipment connected to it. Calculate the minimum standard power of the stabilizer in advance, when calculating, you must not forget to take into account a small "power reserve" - ​​about 20% of the total value.

The algorithm of actions that you can resort to when calculating the power of the stabilizer is quite simple:

  • think how many devices, in addition to the washer, will be protected by means of an acquired stabilizer;
  • read the instructions for each piece of equipment, find the amount of power consumed by the equipment in the manual;
  • add all the values ​​found (for example, you fixed a number of about 3.5 kW);
  • add a small margin of 20% of the amount received.

In our case, the power of the potential stabilizer cannot be less than 4.2 kW (3.5 * 1.2 = 4.2). When purchasing a security element, rounding off the value obtained by calculations can be done exclusively upwards.washing machine stabilizer

Another criterion that you should pay attention to when choosing a stabilizing element is the number of phases. Buying a protective equipment for a washing machine and other household appliances, buyers are wondering which stabilizer is suitable, single-phase or three-phase.It depends on the wiring of each particular house, in most cases the electrical network of high-rise buildings is single-phase, but there are exceptions.

Therefore, study the electrical panel; the meter always indicates how many phases the electrical wiring has. If it is one, then the stabilizer will need a single-phase, if three, then you can purchase both one three-phase protective element, and three single-phase. However, when connecting several stabilizers at once, you can not do without the help of a professional electrician.

When connecting the washer to a stabilizing element, be sure to install a residual current circuit breaker or a difavtomat for greater power supply safety.

RCD will protect the washing equipment from strong power surges that go beyond the boundaries of the stabilizer. In the absence of experience with electrical wiring, it is better to entrust the installation of protective devices to the master.
