Patent ID: 6867955

Claim:
An arc discharge protection apparatus to prevent arc discharge from occurring in a high voltage output zone caused by abnormal conditions, the high voltage output zone including a power supply unit to provide power supply input, a control unit to provide voltage distribution signals, a driving unit to receive the power supply and the voltage distribution signals and transform voltage, a voltage boosting unit to receive the transformed voltage and transform to a high voltage and a load connecting to a high voltage output end of the voltage boosting unit, the arc discharge protection apparatus comprising: an electrode plate for absorbing high voltage arc discharge signals released by the voltage boosting unit; a voltage switch unit for receiving the high voltage arc discharge signals absorbed by the electrode plate and transforming to low voltage arc discharge signals; a rectification unit for receiving and rectifying the low voltage arc discharge signals of the voltage switch unit and outputting an arc hybrid wave; and a trigger unit for detecting the arc hybrid wave and outputting a trigger signal to stop operation of the control unit or the driving unit to prevent the arc discharge from occurring.
