引言目前,工厂企业供电系统中大都安装了无功功率自动补偿制器,该控制器是根据企业功率因数的高低自动投入或断开容器组,使功率因数(cosφ)接近于0.95,其节电效果是非常著的。供电企业要求160kVA以上的高压供电工业用户(包乡镇工业用户)、装有带负荷调整电压装置的高压供电用户
INTRODUCTION At present, most of the power supply systems in the factories and enterprises are equipped with automatic reactive power compensation system. The controller automatically inputs or disconnects the capacitor groups according to the power factor of the enterprise, so that the power factor (cosφ) is close to 0.95. The effect is very great. Power supply enterprises require high-voltage power supply industrial users above 160kVA (including rural industrial users) and high-voltage power supply users with load-regulated voltage devices
