| 摘要 |
The present invention relates to power supply compensation, particularly relates to a customer intelligent reactive power automatic compensation energy-saved device, which includes an intelligent reactive power compensation regulator, a plurality of branch capacitor control contactors, a plurality of capacitor banks and a current transformer. Said intelligent reactive power compensation regulator is provided with a sampling current input, a sampling voltage input, an external AC contactor power bus and a plurality of output control lines, said sampling current input is connected to the current transformer, said sampling voltage input is connected to the power supply, said external AC contactor power bus is connected to a live wire of the power supply, said capacitor banks are connected to the power supply through the branch capacitor control contactors. The present invention can adjust the compensation reactive power by turning on and cutting off a plurality of capacitors, its adjusting compensation precision achieve 10/00 or more of total reactive power, the present invention realizes cosphi=1 and energy-saved.
