Abstract

Abstract This paper describes cause and effect of an electrical arc fault in industrial TS 6/0.4 kV. Results of insulation resistance test, dielectric withstand test, thermographic inspection, testing of LV installation, as well as recorded data analysis are presented in detail and an events explanation is given. The aim of this paper is to show the purpose of complex testing, both during the events of the accident and during the preventive maintenance. It has also been recommended to analyse calculations of short-circuit currents and the effect of an electric arc on the staff in power facilities, the so-called “arc flash”.

电力设施中电弧现象的停电分析
摘要本文介绍了一起工业TS 6/0.4 kV电弧故障的原因及影响。详细介绍了绝缘电阻试验、耐介质试验、热成像检验、低压装置试验和记录数据分析的结果,并给出了事件解释。本文的目的是展示复杂测试的目的,无论是在事故发生期间还是在预防性维护期间。还建议分析短路电流的计算和电力设施中电弧对工作人员的影响,即所谓的“电弧闪光”。
