Expanding the list of household appliances with engineering equipment inevitably increases the load requirements in the power grid. Along with this, the risk of failure of the device during power surges also increases. Therefore, owners of houses with expensive home appliances are advised to purchase equipment that stabilizes network parameters. Especially for domestic use, compact and easy-to-use devices are produced that minimize the likelihood of such drops. The traditional solution is an electromechanical stabilizer, which has basic functionality and a familiar interface.
What is special about electromechanical models?
Today's market offers mainly relay and electronic models of stabilizers, which have many advantages of their own. For example, electronic instruments show a combination of high accuracy, reliability and ergonomics, although they are more expensive than their competitors and are usually larger. Most often, there is a choice between affordable stabilizer models. Relay or electromechanical - which one is preferable? First optioncharacterized by low adjustment accuracy, noisy operation and at the same time the lowest cost. In turn, electromechanical devices are capable of providing accuracy and resistance to overloads sufficient for domestic use. They are also sensitive to temperature fluctuations and lose to analogues in stabilization speed.
The pros and cons of electromechanics are determined by the principle of operation. An automatic converter is introduced into the circuit of such models, which is located in the initial winding of the main booster transformer. Direct adjustment is made by manipulating the graphite brush contact associated with the servo. Therefore, the electromechanical stabilizer requires more time to react, sometimes it makes noise at high loads, but it allows you to more accurately adjust the network parameters.
Single or two-phase?
One of the basic divisions of stabilizing equipment, which will determine the possibilities for its operation. For home use, single-phase appliances are more often recommended, since they are designed to serve a 220 V network. Obviously, most household appliances are powered by the same sources. Three-phase stabilizers work with a 380 V network and are basically oriented towards operation in production conditions, in construction and industry. But at home they may be needed, albeit not in a regular mode of use. For example, to protect against overloads of electric furnaces, welding equipment orpowerful pumps. One more point should be taken into account. The fact is that single-phase electromechanical stabilizers for 220 V can be network (standard models) and trunk. The first devices are usually connected to the network, and the main ones are introduced into the central electromechanical wiring and thus serve all the devices and equipment that are used at the target site.
The main characteristics of the device
The primary characteristic of stabilizers is directly related to their function. This is the amount of active power, which in the case of household models can average 5-7 kW. Of course, if desired, you can find devices for 9, 22 or more kW. The choice depends on which devices a particular electromechanical stabilizer should work with and in what quantity. The total load of all serviced devices is calculated, and the same active power is derived from it. At the same time, for safety reasons, experts recommend adding another 20-25% to the calculated indicator.
The next characteristic is the stabilization range. This is the spectrum in which the equipment will be able to control the magnitude of the voltage, ensuring the safety of the devices. In particular, the best electromechanical voltage stabilizers cover the range from 130 to 280 V. Inexpensive budget models operate in the corridors of the order of 140-260 V. Characteristics such as accuracy and stabilization speed are also important. In terms of accuracy, such instruments may show deviations inwithin 1.5 to 3%, and the reaction rate is small - 5-10 V / sec.
Reviews on stabilizers ORTEA Vega
Italian manufacturer, which is considered one of the leaders in the segment, but does not abandon traditional solutions. The Vega family of stabilizers includes models of various types of power from 2 to 15 kW - this is a line for domestic use and summer cottages. The owners of these devices note the high quality of the design, which is manifested in the well-coordinated work of mechanisms with graphite rollers and the durability of the filling. In addition, if a typical electromechanical stabilizer is associated with small delays in response to network fluctuations, then Vega devices instantly respond to voltage changes. At the same time, both high accuracy and a wide range of coverage of operating values are maintained. Some models work with limits from 123 to 314 V. However, for such advantages you have to pay a considerable amount - an average of 20-25 thousand rubles.
Reviews on the model SDWII-6000-L from RUCELF
Another good option from the category of electromechanical stabilizer models. First of all, the device deserves attention due to its convenient mounting system - as users note, it is enough to install it once on the wall and not return to the topic of installation again. It does not take up much space, does not overheat and makes almost no noise. As for the working qualities directly, the electromechanical voltage stabilizer in the SDWII-6000-L modification is highly valuedfor fast adjustment speed, accuracy and a wide range of options, including the ability to start delay and bypass.
Reviews about the model "Resanta ACH-5000/1-EM"
It is impossible to ignore the products of the most popular domestic manufacturer of stabilizers. The model under consideration is also characterized by quite attractive adjustment accuracy indicators and, as practice shows, it maintains performance even under conditions of frequent voltage drops. The only negative is the limitations on wide voltage ranges. This electromechanical stabilizer is not recommended for regular wide-range swings, since the circuit equalization rate is only 10 V/sec.
What else to consider when choosing?
If the stabilizer suits the main electrical parameters, then you can move on to the ergonomic qualities of the device. This applies, in particular, to the implementation of the interface through which the user interacts with the technology. A modern electromechanical stabilizer in many versions is equipped with an information display. This panel displays all the necessary network parameters, including voltage, load indicator, etc.
Compatibility with target equipment should also be considered. Not all devices and technical means are really protected if a voltage stabilizer is connected to them. An electromechanical voltage regulation device, for example, turns out to be ineffective when working with heating equipment equipped with a heating element. The same applies to equipment with increased starting currents, for which voltage drops are a natural condition for operation.
Conclusion
There are many different aspects to consider when choosing the right stabilizer. And, perhaps, the most responsible decision will be the initial determination of the type of device. Which stabilizer is better - relay or electromechanical? If we are talking about domestic use, then electromechanics is more profitable because of the resistance to loads and the accuracy of adjustment. As for relay models, they perform well in cases where network parameters need to be adjusted in unpredictable conditions. This also applies to differences in wide ranges, and external influences, and other factors that may affect the operation of the device.
