摘　　要：目前很多煤矿电气设备厂家对自身的知识产权保护都十分重视,在编制产品说明书时对设备的工作原理写的很少很简,在电气图上也会做一些手脚。这对于想深入了解这些设备的技术人员来说很不利;对于把这些设备作为教学设备的学校老师来说也增加了很大的难度。因此,我想对QJZ400磁力启动器的工作原理做一个介绍。希望能对有关人员有所帮助。At present a lot of coal mine electrical equipment facto-ry attaches great importance to their own intellectual property rights (ipr) protection , so the working principle of equipment usually is very brief in introduction , which is not good for technicians who want to understand the equipment and school teachers who take those equip-ment as teaching machines . Therefore , I want to introduce the working principle of QJZ400 magnetic starter , hoping to be able to help related personnel .
