矿用隔爆电器故障查询与排除教学中的几点体会矿用隔爆电器故障查询与排除教学中的几点体会 内容摘要: 矿用隔爆型电气设备在煤矿生产中具有举足轻重的地位,尽管生产厂家众多,但其原理是基本一样的,因此在教学中首先要教会原理,让学生掌握煤矿隔爆电气设备原理、应用以及故障的基本查找方法是非常重要的
本文以 QJZ-315
1140 型矿用隔爆型启动器为例,对矿用隔爆电气设备的故障查询和排除作一简单介绍,对矿山机电类专业的教学仅作抛砖引玉
关键词:矿用隔爆型、真空电磁启动器、主回路、控制回路、保护回路、先导回路 Abstract: Mine explosion-proof electric equipment play a decisive role in coal mine production, although many manufacturers, but the principle is basically the same, so in teaching principle of first to the church, let the students grasp coal mine explosion-proof electrical equipment principle, application and basic fault locating method is very important
In this paper, take the QJZ 315 / 1140 type flameproof starter as an example, the mine flameproof electrical equipment fault diagnosis and elimination for a brief introduction
