Abstract

Abstract: Aiming at the problem that UHF partial discharge detection device carried by UAV is affected by the charged distance of substation equipment, it is necessary to miniaturize the device from the three aspects of small sensors, expansion interfaces and data processing. By combining laboratory and on-site test results, PRPD-PRPS spectra of three types of discharges are obtained, including suspended, tip and surface discharge. The relationship between discharge signals and distance is studied, and the device is verified to have good sensitivity, high reliability and convenient operation at the substation site. This device can provide a reference for the UHF detection method through UAV and a new method of intelligent inspection for partial discharge of power equipment.

Key words: ultra-high frequency(UHF), partial discharge, unmanned aerial vehicles(UAV), miniaturization
