摘要

提出了一种有载调压过程中互斥晶闸管组的通断控制方法。采用电流在过零点的瞬间来控制互斥晶闸管组的通断以实现有载调压过程限制调压绕组过电流。通过理论分析及对实验波形的分析

证实了该方法实现快速、无电弧、无冲击、平滑地调压的可行性。该方法还可以用于感性负载的电源的切换以及备用电源自投入。

Abstract

A method of switching mutual repulsive thyristors in the process of on-load tap changer is proposed.Excess current of transformer tap changing winding is limited by controlling the switching of mutual repulsive thyristors at the instantaneous of current passing zero.Theoretical analysis and experimental waveforms show that this method can switch on-load transformer tap fast and smoothly and has no electric arc.This method can also be applied to switch electrical source of inductive load or bring-in spare power supply.
