摘要
The present invention relates to a method of extinguishing an electric arc, which occurs in low or high voltage switchgears, by pulse discharge. The electric arc is cut like a “fuse” by connecting a condenser (201) to both ends of the electric arc at the moment when it occurs and discharging the condenser (201) through the electric arc. The condenser is charged using a resistor (202) and a diode (203), and its discharge is adjusted by some auxiliary contacts.
