Novel high -voltage electroscope

The utility model relates to a whether high voltage system checkout facility electrified detection device, especially a novel high -voltage electroscope. Its characteristics are: including surveying electrode contact, should survey electrode contact and pass through negative logic NOR gate integrated circuit and be connected with audible -visual annunciator to can report to the police when electroless and not report to the police when having detected the electricity detecting, still include DC power supply, thereby this DC power supply is connected the power supply with aforesaid negative logic NOR gate integrated circuit and audible -visual annunciator respectively. The utility model belongs to multi -functional, the portable power frequency high -voltage electroscope of multipurpose, it is accurate reliable to have realized detecting, and the structure is dexterous light, cost low cost, the feasible simple effect of method. And has a following advantage: 1, adopt the low level trigger control of negative lo
