摘　　要：随着煤炭行业的不断发展,煤炭供电系统也在不断进化,随之产生新的安全问题。传统保护逐渐不能适应新的需求,亟需革新。分析了当今煤矿供电系统弧光接地的产生及其危害,探讨煤矿传统保护的局限,提出了分布式弧光保护系统方案,补足了传统保护的短板。With the continuous development of the coal industry,the coal power supply system is constantly evolving,and new safety issues have arisen.Traditional protection is gradually unable to adapt to new demands,and it is in urgent need of innovation.The generation and hazards of arc grounding in the current coal mine power supply system are analyzed,and the limitations of traditional coal mine protection are discussed,and a distributed arc protection system scheme is proposed,which complements the shortcomings of traditional protection.
