The SBW series 3 phase 30kVA to 1000kVA high power voltage stabilizer consists of a compensation transformer, a voltage regulator, a transmission mechanism, a brush contact system, a cabinet, and a control system. The surface of the cylindrical winding of the voltage regulating transformer is polished to remove the insulation and has a smooth conductor surface for good contact with the brush. The transmission mechanism is composed of a servo motor, a sprocket, and a chain.
When the external power supply network voltage fluctuation or load changes cause voltage fluctuations. The stabilizer can quickly react to automatically maintain the output voltage stability. Compared with other types of voltage stabilizers, this stabilizer has the advantages of large capacity, high efficiency, no wave open distortion voltage regulation balance, etc. It can be used in any load with instantaneous overload and long-term continuous operation. The voltage is switched freely, and the regulator is provided with overvoltage, under-voltage, overload, short circuit, overcurrent, reverse phase, phase loss, phase sequence protection, and automatic mechanical fault protection, and the voltage stabilizer is small in size, easy to install, reliable operation, and so on.
