摘要
在分析小电流接地供电系统单相接地故障特征的基础上,介绍国内外各种检测方案的原理、存在的问题和不足。提出应重视接地故障中的间歇性电弧现象,研究间歇性电弧故障机理及所产生的暂态信号的特点和利用方式。
:Based on analyzing the characteristics of single-phase earth fault detection for small current neutral grounding system,this paper introduces the principles and deficiencies of a variety of detection schemes both at home and abroad.The paper also proposes to pay more attention to an investigation on the arc process with intermittence,and its mechanism and the characteristics of its transient message during earth fault.
