Integrated intelligent adjustment and compensation capacitor bank

The invention relates to an integrated intelligent adjustment and compensation capacitor bank, which comprises an intelligent adjustment and compensation capacitor bank switch circuit connected with an intelligent adjustment and compensation capacitor bank control circuit, and is characterized in that: the intelligent adjustment and compensation capacitor bank switch circuit comprises at least one capacitor which is accessed between two phase lines and between the phase line and a null line of a three-phase four-wire alternating current circuit, and each capacitor is connected with respective alternating current mutual inductors and respective switches in series; and the intelligent adjustment and compensation capacitor bank control circuit comprises an external control signal input circuit, an alternating current circuit transforming and sampling circuit, a keyboard display circuit, a temperature detection circuit, an RS232 serial communication interface circuit, an RS485 serial communication interface circuit, a state signal output circuit, an alternating current zero-crossing detection circuit and a relay isolated driving circuit, which are connected with an embedded microprocessor. The integrated intelligent adjustment and compensation capacitor bank has the advantages of fewer devices, small temperature rise, small volume, low power consumption, simple structure, high price performance, good energy-saving effect, long service life and the like.
