目前,一般中小型电力排灌站为了提高系统功率因数与供电电压质量,多数是采用PGJ1型静电电容器屏来补偿无功功率.PGJ1型电容器屏有几种类型,其中PGJ1-1.2型带有无功功率自动补偿控制器,配一只取样电流互感器接在无功补偿的线路中,可以根据取得的负荷无功功率的消耗,自动地控制屏内并联电容器组投入系统运行的组数,使系 At present, in order to improve system power factor and supply voltage quality, most small and medium power irrigation and drainage pumping stations mainly adopt PGJ1 type electrostatic capacitor screen to compensate reactive power.PGJ1 type capacitor screen has several types, of which PGJ1-1.2 type has reactive power Power automatic compensation controller, with a sample current transformer connected to the reactive power compensation circuit, according to the load reactive power consumption, automatically control the number of shunt capacitor banks into the system operation,
