Abstract

The invention discloses a non-contact high voltage electroscope. The non-contact high voltage electroscope comprises a microprocessor module. An output port of the microprocessor module is connected with an indication module, an input port of the microprocessor module is connected with an oscillator module and a ranging module, and the input end of the oscillator module is connected with a sensing module. The microprocessor module comprises a timer and a cache, and the indication module is an acousto-optical indication module. The oscillator module comprises a voltage-controlled oscillator, and the voltage-controlled oscillator is connected with the microprocessor module after being connected with an audion in series. The sensing module comprises a sensing antenna. The non-contact high voltage electroscope can solve the problem that when an existing non-contact high voltage electroscope measures electric field intensity in a high voltage electromagnetic environment in a direct measurement mode, interference is likely to be caused, and thus measurement accuracy is low.

Description

technical field [0001] The invention belongs to the field of electric equipment, and in particular relates to a non-contact high-voltage electroscope capable of improving measurement accuracy. Background technique [0002] The Chinese patent with the publication number CN103344818A discloses a non-contact electrometer, which includes a sensing module, a distance measurement module, a processing module, a transmission module, and an alarm module. The above-mentioned non-contact electrometer detects the electric field of the object to be measured Intensity, and the distance from the electroscope to the object to be measured, according to the corresponding relationship between the distance and the electric field strength, it is judged whether the object to be measured is charged, but due to the interference of the high-voltage electromagnetic environment, the measurement accuracy of directly measuring the electric field strength is low. Subsequent experiments will have a certai...
