摘要
本文着重介绍了煤矿电网微机保护的特点，保护的数学处理方法；基于该方法的保护装置，以单片微机为中心，可完成对电网过流、漏电等多种故障的保护。
This paper emphatically introduces the features and the numeral processing meth-ods of the protection of clectrified wire netting microcomputer in coal mines.The protectingdevices developed with this method and centered on the monomicomputer can fulfil the protec- tion of elcctrified wire netting and against lcakage of electricity and many other troubles.
