Reactive dynamic compensation multi-stage regulation electric cabinet for distributing transformer on pole

The utility model discloses a reactive dynamic compensation multiple stage regulation electric cabinet for distributing transformer on a pole. The utility model is suitable for the reactive dynamic compensation on the spot of a low voltage and small size motor. The input terminal of an electronic regulator Rc is connected with a terminal a, the output terminal is connected with gate terminal of a half control type thyristor ac switch, an anode is connected with a knife smelting switch K and the upper end of a fixing power capacitor C1, a cathode is connected with one end of the power capacitor; the other end of the knife melting switch K is connected with a terminal b, the lower end of the fixing power capacitor C1 is connected with a neutral point of a compensating circuit Y0, and the other end of the power capacitor is connected with the input end of a neutral point current limiting reactor whose output end is grounded. The utility model overcomes the defects of the prior art; the utility model has the advantages of multiple regulating stages, constant compensation for the no load loss, and realization for the optimized regulation.
