1. a kind of electric bypass equipment, including:

  • For across the first and second terminals of the connection of electric component;

    Electricity triggering by-pass switch, its changeable short circuit to be formed across first and second terminal;

    AndFirst control circuit, is connected between described first and second terminal, and the first control circuit includes what is intercoupledFirst and second windings, first winding is isolated with second winding, and the first control circuit is configured to:

    When normal operating voltage is in the presence of first and second terminal, prevent what is flowed between described first and second terminalElectric current flows through first winding;

    AndWhen overvoltage is in the presence of first and second terminal, permitting current is between described first and second terminal and JingCross first winding and flow, and thus cause the current impulse in second winding,Wherein described second winding is electrically coupled to the electricity triggering by-pass switch so that the electricity caused in second windingSwitch-over control signal is served as in stream pulse, to close the electricity triggering by-pass switch, and is consequently formed across described first and secondThe short circuit of terminal.
