浅谈易引起电气火灾的接地故障

摘要

This paper analyses the ground fault that can easily cause electrical fire in low-voltage distribution system of civil buildings, and respectively discusses the hazards of ground fault, the preventive measures and the problems when only using residual current protector to detect ground fault, and points out the development direction of ground fault detection system.%本文对民用建筑物低压配电系统中易引起电气火灾的接地故障进行分析，分别从接地故障的危害、现有接地故障的预防措施及单纯使用剩余电流保护器检测接地故障存在的问题等进行论述，指出了接地故障检测系统的发展方向。
