摘　　要：介绍用MCS - 96系列的 80C196KC单片机构成的智能化矿用隔爆小型真空磁力启动器保护系统 ,其中短路保护、断相保护、过载保护均采用软件实现。故障闭锁 (短路闭锁、断相闭锁、漏电闭锁 )功能解决了因送电前的短路、断相、漏电导致送电后产生电火花的问题。该系统经实验室模拟实验 ,各项指标均达到了设计要求 。The protection system of small intelligent flameproof vacuum magnetic starter used in mine which is composed of 80C196KC single chip microcomputer of MCS 96 series was introduced, in which short circuit protection, open phase protection, overload protection were realized by software. Particularly, the function of fault locking settled the problem which causes electric spark after power on because of short circuit, open phase, leak electricity before power on, thus avoiding causing coal dust or gas explosion accidents. The system was proved through the lab simulating test that all its indexes satisfled the demands of design and achieved good results.
