摘要

为了让变电运行人员进一步了解预调试消弧线圈的基本原理

解除部分运行中遇到的问题

笔者针对现场预调式消弧线圈使用过程中运行人员存在的一些认识误区

详细分析了预调式消弧线圈实现消弧的基本原理。首先从不平衡电压的产生及消弧线圈对不平衡电压有放大效应的基本概念入手

接着分析了消弧线圈补偿电网中故障发生前后系统的等效电路

建立起了两个电路之间的联系

进而分析了这个联系对预调式消弧线圈最终实现补偿所起到的关键作用。最后给出了预调式消弧线圈在现场运用中的一些运行结论。

Abstract

In order to introduce the principle of pre-coordinated arc-suppression coil and then solve some problems in its operation

this paper analyzes the occurrence of imbalance voltage and the magnifying effect of arc-suppression coil

as well as the equivalent circuits of the compensation grid of arc-suppression coil before and after fault.Then

the relation between the two circuits is built up.Moreover

the effect of the relation on realizing capacity current compensation with the pre-coordinated arc-suppression coil is discussed.Finally

several conclusions about site operation of the pre-coordinated arc-suppression coil in substations are drawn.
