After electrical deoscillator RL and high-speed eddy switch K0 series connection in parallel with series compensation capacitor C, controllable silicon SCR respectively, and this parallel connection
One end of end is connected with one end of the first isolation switch G1, the other end of this parallel connected end and one end phase of the second isolation switch G2
Even, the other end of the first isolation switch respectively with the end of incoming cables AL1 of power distribution cabinet, being connected of one end of the 3rd isolation switch G3, the
The other end of two isolation switch G2 respectively with the leading-out terminal AL2 of power distribution cabinet, being connected of the other end of the 3rd isolation switch G3.Described
Series compensation capacitor C, controllable silicon SCR, high-speed eddy switch K0, electric discharge antivibrator RL, the first isolation switch G1, the second isolation
Disconnecting link G2 and the 3rd isolation switch G3 is installed in power distribution cabinet.Described high-speed eddy switch K0 is by the control being arranged in power distribution cabinet
Device processed controls it and cut-offs.Described current limliting antivibrator RL is in parallel is formed by inductance L and resistance R, is used for limiting series compensation capacitance
Discharge impact electric current after device C short circuit.Described high-speed eddy switch K0 is eddy current driving, vacuum extinction chopper.
Described series compensation capacitor C, for the induction reactance of compensated line, reduces the pressure drop of remote circuit, and then promotes negative
Carry side voltage；Described controllable silicon SCR, after system short-circuit, short circuit series compensation capacitor C in 200us, prevents series compensation
