ABSTRACT:
An apparatus for extinguishing the arc which occurs between a pair of electrodes separated in the switchgear when the high voltage loaded switchgear is opened. The earliest arc is detected which occurs between a pair of electrodes. When the earliest arc is detected, a gate signal is transmitted to a pair of thyristor connected anti-parallel between a pair of electrodes. Then among those thyristors, a thyristor located in the forward direction relative to the polarity of power supply becomes conductive. As a result of the thyristor being conductive, the arc occuring between a pair of electrodes is eliminated.
