The invention discloses a reactive power compensation capacitor switching circuit, which comprises a power supply preset circuit, drive circuits and a wiring terminal. The wiring terminal is connected with a reactive power compensation capacitor; a common anode port of the wiring terminal is connected with the output end of the power supply preset circuit, and a common cathode port is grounded; and a controller module outputs a switching tube drive signal, and is connected with the wiring terminal through the drive circuits. The drive circuit comprises a first switching tube and a second switching tube. The polarities of on signals of the first switching tube and the second switching tube are opposite. One end of an active end of the first switching tube is connected with the output end of the power supply preset circuit, and the other end is connected with one end of an active end of the second switching tube, and the end is connected with a capacitor connection port of the wiring terminal. The other end of an active end of the second switching tube is grounded. The invention also provides a switching method of the switching circuit, and a transformer area complete controller comprising the switching circuit and method. The reactive power compensation capacitor switching circuit and switching method are suitable for common anode and common cathode two kinds of wiring modes, and the circuit is simple and reliable.
