Air switch and air switch control method

The invention discloses an air switch and an air switch control method and relates to the field of electrical fire safety protection. The air switch comprises a fault arc detection module, a master control module and a tripping action execution module. The fault arc detection module is used for detecting whether a current load circuit has a fault arc, and when the current load circuit has the fault arc, sending a fault signal to the master control module; the master control module sends a tripping control signal to the tripping action execution module when judging that tripping operation needsto be carried out according to the fault signal; and the tripping action execution module converts the tripping control signal into an execution action of an electromagnetic coil to finish the tripping operation. The air switch can detect the fault arc, and carry out tripping operation after the fault arc is detected, so that safety of the load circuit can be ensured. 本发明公开了种空气开关和空气开关控制方法，涉及电气安全消防领域，其中，空气开关包括故障电弧检测模块、主控模
