电力变压器有载分接开关故障及处理对策

摘要

In the charged operation of the transformer,on-load tap-changer voltage regulator is used to transform the position of the primary and secondary coil tap,change its coil number of access turns,and adjust the discretion of the operating voltage.In this paper,the common failures and countermeasures in the operating mechanism are analyzed.%有载调压分接开关是在变压器带电运行中，用于变换一次和二次线圈的分接位置，改变其接入有效线圈匝数，运行电压的高低调整的电力器件。有载调压分接开关由选择开关、切换开关和操作机构等组成。本文分析了操作机构部分中常见故障及处理对策分析。
