Non-contact high-voltage electroscope

The utility model discloses a non-contact high-voltage electroscope, and the electroscope comprises a microprocessor module. The output port of the microprocessor module is connected with an indication module, and the input port of the microprocessor module is connected with an oscillator module and a ranging module. The input end of the oscillator module is connected with an induction module. The microprocessor module comprises a timer and a buffer memory, and the indication module is a sound-light indication module. The oscillator module comprises a voltage-controlled oscillator, and the voltage-controlled oscillator is connected with a triode in series and then connected with the microprocessor module. The induction module comprises an induction antenna. The electroscope can solve a problem of low measurement precision caused by that a conventional non-contact high-voltage electroscope is liable to be disturbed when employing a mode of direct measurement to measure electric field intensity in a high-voltage electromagnetic environment.
