KGK-A型矿用一般型高压电容补偿开关柜,是由济南煤矿设计院与济南第二电器设备厂联合开发的。1991年8月完成样机试制,12月份样机安装于肥城矿务局查庄煤矿井下-350水平变电所,经三个多月工业性运行,情况良好,达到原设计要求。根据矿上实测资料表明:功率因素平均提高14.6％;电压平均提高1.7％,而电流则水均可降低14.2％。
KGK-A-type mining general high voltage capacitor compensation switchgear, Jinan Coal Mine Design Institute and the second by the joint development of electrical equipment factory. In August 1991, the prototype was prototyped. In December, the prototype was installed at the substation at Zhazhuang Coal Mine -350 level in the Feicheng Mining Bureau. After more than three months of industrial operation, the prototype was in good condition and the original design requirements were met. According to the measured data from the mine, the average power factor increased by 14.6%, the voltage increased by 1.7% on average, and the current water decreased by 14.2%.
