| 摘 要： | 高阻抗式消弧线圈是一种由一对反并联晶闸管控制的随调式消弧线圈。为了研究其在配电网中的工作特性，本文主要研究消弧线圈在中性点电压突然升高即发生单相接地故障时的暂稳态过程，找出影响响应时间和接地残流的因素，为此设计新的控制策略并通过仿真分析证明可提高消弧线圈的响应时间和补偿效果。

RESEARCH ON HIGH SHORT-CIRCUIT RESISTENCE ARC SUPPRESSION COIL IN SINGLE-PHASE TO EARCH FAULT |
| |
| Abstract: | High short-circuit resistence arc suppression coil is a type of adjustable arc –suppressing coil controlled by pair of anti-parallel thyristor. In order to study the working characteristics of arc suppression coil in power distribution network,this paper study on transient and steady-state process of arc suppression coil when neutral-point voltage suddenly rise.The correspondent controlling strategy has been designed by finding out the factors that influence the response times and residual current,greatly reducing the response time and improving the compensation effect. |
