摘要
介绍QJZ—400/1140(660)矿用隔爆兼本质安全型真空电磁起动器的工作原理、控制、保护及相关性能。通过煤矿井下中央水泵房的应用表明,该起动器不仅保护功能齐全,使用方便,而且方便维护,可实现泵房的无人值守。
The paper introduces the working principle, control, protection and related performance of QJZ-400/ 1140(660) mine flameproof and intrinsically safe vacuum electromagnetic starter. The application of this starter to the central pump house underground coal mine shows that it has complete protection functions and is easy for operation and maintenance, thus realizing unmanned watch for the pump house.
