A zinc oxide surge arrester live testing device

Abstract

This utility model relates to the field of surge arrester technology, specifically disclosing a live-line testing device for a zinc oxide surge arrester, including a cross tube; a long operating tube and a short operating tube are inserted into both ends of the cross tube; a support shaft is damped and slidably inserted into the cross tube; a function box is fixedly connected to the end of the long operating tube; a mounting plate is fixedly connected to the end of the short operating tube; an operating terminal is fixedly connected to the mounting plate; a control terminal is placed inside the function box; by adjusting the distance of the support shaft inside the cross tube, the height of the operating terminal from the ground is adapted to the zinc oxide surge arrester, then the lower end of the support shaft touches the ground, the long operating tube is held and the operating terminal is moved forward to clamp the zinc oxide surge arrester, and then the control terminal is operated to perform live-line testing of the zinc oxide surge arrester, thereby keeping personnel away from the live zinc oxide surge arrester and making live-line testing safer.
