Arc extinguishing control circuit

The utility model belongs to the technical field of arc extinguishing, and relates to an arc extinguishing control circuit, which comprises a CPU (central processing unit), a current sensor circuit, a comparison circuit, an electronic switching circuit and an anti-thunder and anti-surge protection circuit which are electrically connected. Wherein the CPU is used for processing an arc extinguishing signal and controlling the on-off of the electronic switching circuit, the current sensor circuit is used for detecting current, the comparison circuit is used for checking a current threshold value, and the electronic switching circuit is used for carrying out high-speed on-off on the arc extinguishing control circuit. The lightning protection and surge protection circuit is used for protecting the arc extinguishing control circuit from being struck by lightning, the comparison circuit and the CPU are used for judgment, comparison is carried out according to a preset current threshold value, the current threshold v
