试论低压配电系统的接地故障保护

摘要

分析了接地故障引起火灾的主要原因，归纳了造成接地故障的因素，在此基础上提出了预防低压配电系统接地故障事故发生的措施，以降低火灾和人员伤亡事故的发生率。%The thesis analyzes ground-fault fire causes,summarizes major factors leading to ground-fault,and puts forward measures of preven-ting ground-fault of low-voltage distribution system,with a view to reduce fire occurring rate and casualty accident rate as well.
