摘　　要：以某矿中的低压馈电开关为研究对象,基于漏电保护原理,对低压馈电开关使用现状及故障原因进行分析,包括分开关不动作和总开关延时过长,并提出相应的改造方案。经理论验证,所提出的改造方案合理,为提高综采工作面的安全性奠定了理论基础。Taking the low-voltage feed switch in a mine as the research object,based on the principle of leakage protection,this paper analyzes the current situation of the low-voltage feed switch and the causes of its faults,including the non-operation of the separate switch and the excessive delay of the total switch.At the same time,the corresponding reconstruction scheme is put forward.Through theoretical verification,the proposed reform scheme is reasonable,which lays a theoretical foundation for improving the safety of fully mechanized mining face.
