Maintaining the optimal parameters of the electrical network is an important condition for protecting the supplied equipment. Voltage drops are more common in household networks, but production facilities, with all the additional security measures, may experience fluctuations in the current supply. Industrial voltage stabilizers are designed for such cases, which are used as part of engineering and technological equipment, conveyor lines, individual workshops and even structures.
Features of industrial stabilizers
It is customary to separate household and industrial stabilizers by phase, but this is a conditional classification feature. Indeed, most of these devices are three-phase and operate from a 380 V network. However, there are also 220 V industrial voltage stabilizers, which, with fewer resources, in fact, perform the same tasks of electrical protection of industrial equipment. And in this sense it is worth emphasizing two aspects. Firstly, engineering and technological production facilities are not always more powerful than individual representatives of household appliances. Accordingly, in220 V networks may well exist in construction site or production conditions. Secondly, of course, there are other features that distinguish industrial models, including advanced control methods, higher technical reliability and versatility.
Besides, in modern productions, systems of programmable controllers are increasingly being introduced, allowing from one point to regulate the joint operation of engineering devices and electrical engineering. Many models of voltage regulators for industrial installations rely on this integration capability, thereby facilitating the process of equipment control. Obviously, there is simply no point in communication systems between a home stabilizer and industrial controllers.
Key Features
The stabilizer is mainly determined by the power. This is the potential that covers the total energy consumption of the serviced equipment. As in the domestic sector, in industry, one stabilizer can serve several pieces of equipment. In calculating the optimal variant, one should add the power consumption indicators of the target equipment, then multiply this value by the deviation coefficient in the network and get the power indicator of the desired device. For example, the 10,000 volt voltage stabilizer dominates in the middle segment. An industrial unit of this type cannot be called heavy duty, but it may be suitable for protecting several machines or a climate system with a boiler. The range is also estimateddeviations in voltage values and stabilization accuracy. For example, the input voltage can range from 135 to 450 V in phase. This is the optimal coverage range for industrial devices, although there are more attractive indicators of already specialized types.
Varieties of equipment
In the segment of three-phase stabilizers, there are two main groups of models - electronic and electromechanical. Electronic devices are based on the basis of an automatic transformer, in which step switching of the winding is implemented. The design for performing work functions is complemented by a control relay and semiconductor components in the form of thyristors and sevenstors. Thanks to these elements, a quick adjustment of the circuit parameters is ensured. By the way, it is in this group that single-phase industrial voltage stabilizers with a digital control interface are found. They are similar to household models in terms of control and ergonomics, but have a higher degree of electrical protection. As for the electromechanical models, they control the voltage with a graphite brush. This component is shifted to the sides along the transformer, closing the circuit at the necessary points of the winding. Electromechanics is characterized by increased overload capacity, but its functional elements wear out quickly, and this already negatively affects the accuracy of the equipment.
Reviews on the model Elitech ASN 6000 T
Equipmentmade quite non-standard by the standards of one of the largest manufacturers of engineering equipment - Elitech. The developers used an electromechanical regulation scheme and, with 380 V phase support, endowed the unit with a power of only 6000 watts. And yet, the practice of operation has shown that such characteristics can be acceptable. The device performs well in servicing individual networks and production points. This is the advantage of low-power industrial voltage stabilizers, that they, concentrating on one line of protection, provide higher regulation accuracy and reliability. Also, the operators of this model point to the ergonomics and ease of access to individual functional units.
Reviews of the Progress 8000SL
This is a variant of a specialized model designed for servicing boilers. By the way, the 8000SL stabilizer just demonstrates an example of the convergence of single-phase equipment with full-fledged industrial needs. Suffice it to say that with the support of a 220 V network, the unit has a power of 6400 W, ahead of the previous three-phase model in this indicator. As for the reviews, they indicate the accuracy of the network rectification, compliance with the declared wide adjustment range and the quality of the design. The only downside is the price tag. For comparison, if typical industrial voltage stabilizers with a power of up to 10,000 W are estimated at an average of 30-40 thousand rubles, then the 8000SL modification costs about 60thousand
Reviews about the model "Resanta ASN 15000/3"
One of the best models of domestic stabilizing equipment comes out under the Resanta brand. In this case, the developers offer a very attractive price-performance ratio. With a power of 15,000 W, the industrial voltage regulator of this modification is able to cover several units of high-performance equipment in a three-phase network. In this case, the cost is 30 thousand. In terms of performance, the owners of the equipment emphasize the low error within 2%, the versatility of use, a wide range of supported voltages and small sizes.
What to consider when choosing?
Of course, it is worth starting from the direct operational parameters in the form of input voltage, adjustment accuracy and the principle of operation as such. But also do not miss the opportunity to control and manage equipment. It is known that under production conditions, almost all electrical equipment provides a significant energy consumption. Therefore, the function of automatic control of the voltage stabilizer will not be superfluous. An industrial energy-saving unit with its own operating parameters control system will cope with the primary tasks, but at the same time it will not overload the line above the norm. Also, a modern stabilizer cannot be deprived of an overload protection system with short circuits. These and other additions, together with the self-diagnosis function, must be taken into account in the selection.
Conclusion
The variety of electrical protection and safety systems on the market today can lead to doubts: is the problem of voltage stabilization really so important and expensive equipment is required to solve it? Or is it nothing more than a marketing campaign? In this regard, it should be noted that in the domestic sphere the need for such an addition is not always present. But an industrial three-phase voltage stabilizer introduced into the infrastructure of critical equipment is certainly a useful protective tool. Moreover, such devices are used not only in industries, but also in medical institutions, for example, where an accidental failure of a medical device can cost a human life. Another thing is that the choice of a stabilizer should correspond to clearly formulated tasks.
