SBW Three-phase Power Regulator

Product Overview
This series of products in comparison with other forms of voltage regulator has a large capacity, high efficiency, no waveform distortion, voltage regulation is smooth, applicable to a wide range of loads, can withstand the instantaneous overload, can be a long period of continuous work, manual, automatic switching, and over-voltage, under-voltage, over-current, phase sequence, mechanical failure of automatic protection devices, as well as a small size, light weight, easy
to install and operate reliably and other characteristics. Can be widely
used in industrial and mining enterprises, printing, machine tools, construction sites, schools, hospitals, hotels, agriculture, transportation, post and telecommunications, military, railroads, scientific research and culture and other areas of large-scale electromechanical equipment, metalworking equipment, elevators, medical equipment, microcomputer room computer control equipment, embroidery textile equipment, air conditioning, broadcasting and television, and household appliances, lighting and other places that require voltage regulation. It consists of three-phase (single-phase) compensation transformer, three-phase (single-phase) regulator transformer, transmission mechanism, brush contact system, control system and box, etc., three-phase regulator transformer cylindrical winding surface by grinding
processing, to insulating varnish, was a smooth conductor surface. In order to brush good contact; transmission mechanism by the servo motor and worm gear, worm gear, sprocket, chain; brush contact system structure is reasonable and reliable, to ensure brush pressure; box
using closed cabinet type, small body, good heat dissipation, detection instrumentation position indicated that the instructions are accurate; control system adopts integrated circuits, (microcomputer control), strong control capability, perfect protection function, convenient adjustment, stable and reliable.
