A compensating voltage regulator device and a method for using the compensating voltage regulator device

Abstract

A compensating voltage regulator including chassis, A cavity is arranged in the chassis, A top plate and a bottom plate are arranged in the cavity, Between that top plate and the bottom plate, a three-phase cop bar is fixedly installed, A left-right symmetrical fix mounting of that bottom end surface of the bottom plate is provide with a front-rear extending bottom frame, A left-right symmetricaltop frame is fixedly arrange on that upper end surface of the top plate, At both front and rear end of that top frame, the front and rear ends of the top frame are out of the top plate, At both frontand rear end of that chassis, A lead bar is fixedly installed between that top frame and the bottom frame, The three-phase copper bar is symmetrically provided with a sliding plate which extends leftand right and is slidably matched with a guide rod of a corresponding side, and a carbon brush which is opposed to and slidably matched with the three-phase copper bar is fixedly installed on the sliding plate toward the end face of the three-phase copper bar, and the carbon brush is electrically connected with a compensation transformer installed in the cavity through a cable.

Description

technical field [0001] The invention relates to the field of electric power, in particular to a compensating voltage stabilizer device and a using method thereof. Background technique [0002] Three-phase compensated voltage regulator devices mainly include two types: disc type and column type. Each prior art voltage stabilizer includes: an automatic control circuit, a compensation transformer, a voltage regulator using a motor drive and using carbon brush contact connections. The compensation transformer includes three compensation coils and three compensation excitation coils, and the three compensation coils are respectively located in the three phase lines; the output terminal of the voltage regulator is connected to the compensation excitation coil of the compensation transformer. [0003] The carbon brush and other conductive contact parts slide on the copper wire or copper bar of the voltage regulator. The carbon brush is in different positions, and different output ...

AI Technical Summary

Problems solved by technology

[0004] According to the level of the input voltage, the voltage regulator automatically applies voltages of different sizes and directions to the compensation excitation coil of the compensation transformer, thereby inducing compensation voltages of different sizes and directions on the compensation coil of the compensation transformer. Finally, the unstable input voltage is superimposed with the compensation voltage to output a relatively stable AC voltage. In the prior art, when adjusting the position of the carbon brush, it is often realized by chain transmission, but this transmission method is not enough. Stable, and the accuracy is not high, and when the regulator is running, it often generates a lot of heat, if it is not discharged in time, it will affect the performance of components
