Switching device discharges for ball crack that can long -rangely observe

The utility model provides a switching device discharges for ball crack that can long -rangely observe, include transparent insulating cylinder (23), second electrode (21) of the installation downwards of insulating cylinder (23) top with set up insulating cylinder (23) in and second electrode (21) relative first electrode (22), first electrode (22) relative face that sets up with second electrode (21) all is spheres, still includes atmospheric pressure sensing unit (53) and video shooting unit (2), the ball crack discharge switching device still include with atmospheric pressure sensing unit (53) and video shoot processing unit (3) that unit (2) electricity connects and with communication unit (7) that processing unit (3) are connected. This kind of switching device discharges for ball crack that can long -rangely observe, in the time of can discharging switch motion in emergence ball crack, the automatic image that discharges of shooing to provide radio communication unit transmitter data or image to server or terminal, supply in situ observation and records reserve, improved ball crack discharge switch degree of participating in and test efficiency, also provide real -time warning.
