One of the features of modern houses, cottages and cottages is the presence of a large number of electrical appliances. Products vary in power and size, but have one common property - they are all designed for certain parameters of energy consumed. With significant deviations, the equipment may stop working and even fail. To prevent the breakdown of expensive devices, a voltage stabilizer in the outlet is used - an inexpensive, but effective device.
The feasibility of using a stabilizer
With a critical change in the energy entering the building, household appliances can turn off, break down completely or partially. Power surges are not uncommon. Their cause is the human factor, wear or damage to electrical equipment. Often there is a burning off of the zero wire, which leads to distortions of the levels even within the same apartment.
The effect of voltage drops on different types of household appliances:
- Devices that have compressors (refrigerator, air conditioning, freezer) cannot start and work at a low signal level. The windings of the device overheat, the enamel coating is destroyed, a breakdown of insulation and breakage occurs. The compact stabilizer provides an increase in the signal to the desired level or interruption of the line. Refrigerators after an emergency shutdown begin to work after 7-10 minutes.
- Devices with engines. These include mixers, coffee grinders, fans, meat grinders, microwave ovens. Most of them do not have protection against overheating, which occurs with a large increase in the input voltage. A low signal is also dangerous, because of which the motor stops or burns out.
- Products with electronic control. They built chips with a certain range of operating current. With a deviation up or down, the correct operation is violated. This leads to disconnection and failure of installed programs. This can be eliminated by the stabilizer in the outlet.
- Heating elements. These are kettles, stoves, ovens, heaters. They can fail in case of prolonged operation at high voltage. Elements are not able to remove excess heat, which leads to their combustion. Low current levels do not affect them.
The use of even small and inexpensive outlet voltage stabilizers will help to avoid a lot of unplanned expenses for the repair and purchase of new equipment, instead of spoiled due to surges in the level of electricity.
Stabilizer selection
When choosing point stabilizers, a number of the following factors should be taken into account, based on which priorities are built:
- The number of electricity consumers who need protection from its drops. If they will stand in each room, it is advisable to put one powerful input machine.
- The strength and voltage that goes into real estate. There are devices operating on 220 V and 380 V.
- Type of current. Products can be designed for one or three phases. This determines the configuration, the number of connectors and plugs.
- The presence of grounding. This indicator determines the product model - it will be a built-in stabilizer socket or an external inverter device.
Since single-phase current is supplied to apartment buildings and there is no grounding, devices corresponding to this parameter should be purchased.It should be borne in mind that in most cases there is no opportunity to put a separate input machine. It is advisable to purchase point voltage relays in the outlet, installed where devices that need protection are connected.
Since almost all cottages are equipped with grounding, devices should be purchased appropriate. The removal of electricity during breakdown to the housing will save a person’s life and extend the working capacity of the connected equipment. In this case, you can take low-power stabilizers, designed for a load of up to 500 watts for connecting video equipment, refrigeration units and kitchen appliances. Products with higher load ratings should be purchased for air conditioners, boilers, washing machines and dishwashers.
The best solution for a private building, if it has many powerful consumers, is to install an expensive, but effective input stabilizer, located in a common shield.
Features of the outlet device
Rosette stabilizers are small-sized devices characterized by low weight and attractive appearance.
They consist of such parts:
- Electronics. In various models, it is a board with soldered parts or a microprocessor. Electronic devices measure the parameters of the incoming current, change its parameters to normal and generate commands for the mechanical parts of the device. Commands are transmitted in the form of pulses of a certain frequency in accordance with the program laid down.
- Mechanics. Light models are equipped with springs and clamps, which, when the load peaks are exceeded, break the circuit. Subsequent activation occurs automatically or manually, depending on the model and cost of the device.
The devices have a scale for setting the upper and lower threshold. Range selection is based on connected consumers. Depending on the degree of sensitivity of the equipment, the lower threshold is set at 130-200 V, and the upper one is within 230-270 V. As long as the voltage is within these limits, the electronics equalizes it to the required 220 V. If the set limits are exceeded, the relay turns off the power for 0.3-0.6 seconds. In most cases, this is enough to prevent damage to the equipment. The delay time varies between 5-600 seconds, depending on the characteristics of the connected equipment. Various models are designed to connect one or more consumers with a total power of 0.4-3.0 kW.
Differences from a regular stabilizer
Outlet analogs differ from ordinary household stabilizers in the following parameters:
- Compactness. The size of single models does not exceed 125 × 60 × 80 mm. Devices do not look bulky, organically blending into the interior.
- Light weight. It does not affect the lid and socket.
- Long response time during overload. For stationary products, this happens 8-10 times faster.
- The impossibility of stable maintenance of the desired voltage due to the lack of power transformer windings.
Most of the outlet stabilizers are an effective electronic fuse with the functions of adjusting the current parameters.
