摘要

随着电力系统的不断扩大

开关柜内部故障电弧对电力系统安全稳定运行的影响日益突出

电弧防护也越来越得到重视。笔者简要介绍开关柜内部故障电弧的特性

分析电弧从产生到熄灭的各个阶段;介绍电弧带来的危害

并针对其中几种典型危害进行分析;介绍分析开关柜内部故障电弧的几种常用数学模型

并总结出实际生产中可能产生故障电弧的原因;对现有的在电弧防护方面所做的研究工作就保障人身安全和设备安全两方面分别总结;最后对今后开关柜内部故障电弧防护的研究提出一些建议。

Abstract

With the continuous expansion of the power system

the influence of the internal fault arc on the safe andstable operation of the power system is becoming more and more serious

and the arc protection is also getting moreand more attention. The characteristics of switchgear internal fault arc are briefly introduced

the various stages ofarc from generation to extinguish are analyzed. The harm and several typical hazard caused by arc are introduced andanalyzed. Then

several commonly mathematical model of switchgear internal fault arc are introduced and analyzed

and the causes of fault arc in practical production are summed up. Aiming at the existing arc research

from two as-pects on the protection of personal safety and equipment safety are summarized and analyzed. Finally

some sugges-tions to research of the future of the switchgear internal fault arc protection are put forward.
