Abstract

The invention discloses an electrified tester for a zinc oxide arrester, and relates to an instrument for detecting alternating-current parameters of a metallic oxide arrester in an electrical power system in the process of charged running. The electrified tester comprises a master machine and a slave machine; a current sensor lead wire, a current sensor unit, a program control amplification unit, a current signal processing control unit and a wireless signal receiving module are connected sequentially and are connected with an upper computer; the upper computer is respectively connected with the current signal processing control unit, a liquid crystal display, a keyboard and a mouse to form the master machine; a voltage sensor lead wire, a voltage sensor unit, a voltage signal processing control unit and a wireless signal emission module are connected sequentially to form the slave machine; and the master machine and the slave machine control signals and data through wireless communication transmission. The electrified tester is suitable for detecting total leakage current, resistive current fundamental waves and triple frequency harmonic at regular intervals on the running metallic oxide arrester and checking the running performance of the metallic oxide arrester.

Description

technical field [0001] The invention relates to an instrument for live detection of a metal oxide arrester for overvoltage protection in a power system, in particular to the realization of a metal oxide arrester resistive current live detection, wireless data transmission mode and signal acquisition synchronization mode. Background technique [0002] Metal Oxide Arresters (MOA) have been widely used in power systems due to their superior nonlinear characteristics. Due to the long-term operation under the operating voltage, and the repeated impact of various overvoltages, as well as the damp and aging of the valve plate, the overall performance of the arrester has gradually declined. At present, the operating characteristics of metal oxide arresters are mainly judged comprehensively through live detection and offline detection. [0003] Most of the existing live detection methods of metal oxide arresters adopt detection methods such as total leakage current, resistive curren...
