ZB82—127/20型防爆电钻综合保护控制器(瓦房店防爆电器厂产品。以下简称“综保”)是我矿主要使用的煤电钻综合保护装置,对我矿的安全生产起了很大作用。但我在4个月的维修实践中,对它的原理及设计意图逐步理解,越来越感到它的某些环节设置的不尽合理。既增加了单机成本,又由于环节繁琐而使故障点增加,从而使故障率升高。从现场使用的角度看,由于故障率高,
ZB82-127 / 20 explosion-proof drill comprehensive protection controller (Wafangdian explosion-proof electrical plant products. Hereinafter referred to as “Comprehensive Insurance”) is mine mainly used coal drill integrated protection device, mine safety play a very important Great effect. However, in my 4-month maintenance practice, I gradually understood its principle and design intent and felt more and more that some of its links were not set up properly. Not only increase the cost of a single machine, but also because of the tedious links to increase the point of failure, so that the failure rate increased. From the perspective of field use, due to the high failure rate,
