Abstract
This paper mainly introduces the reasons for the overstep tripping of underground power distribution equipment, and analyzes the plan of preventing the overstep tripping in the underground of Yixing Coal Mine, underground network short ladder delay selectivity, high selective interlock limit break, selective microcomputer limit per hour speed to break over-current protection, are put forward, which makes preparation for late overstep tripping caused by short circuit in the underground distribution system.关键词
