摘　　要：介绍了综采工作面移动变电站的选型方法,对KBSGZY-1 600/6型移动变电站的功能特点及安装使用的注意事项进行了介绍,并在移动变电站的安装使用过程中,出现了漏电误动作的现象。通过对附加直流漏电原理及移动变电站的电气原理图的研究分析,用并联大电容的方法滤除漏电检测回路的干扰电流,解决了移动变电站漏电误动作现象。Introduces the mobile substation selection method of fully mechanized working face,features of the KBSGZY- 1 600 /6 type mobile substation and installation precautions are introduced,In the process of mobile substation install and use,the leakage phenomenon of false action appeared. Based on additional DC leakage principle and mobile substation electrical schematic diagram analysis,use the method of capacitance in parallel filter out interference current leakage detection circuit,solved the mobile substation leakage phenomenon of false action.
