Abstract

The invention provides a lifting device for a zinc oxide arrester resistance current tester. The device comprises a triangular ladder; two sides of the triangular ladder are respectively provided withdouble-link mechanisms; the double-link mechanisms comprise mounting plates fixed on one side of the triangular ladder; a first rocker, a second rocker, a third rocker and a sliding block are arranged on each mounting plate; the sliding blocks are in sliding connection with the mounting plates; the device further comprises cranks; one ends of the cranks are hinged with the middles of the third rockers; the other ends of the cranks are driven to rotate by rotary driving mechanisms; the rotary driving mechanisms are fixed on the mounting plates; a telescopic rod is arranged on two sides, between the sliding blocks of the double-link mechanisms, of the triangular ladder; a fixed box is arranged on the telescopic rod; and a tray used for fixing the zinc oxide arrester resistance current tester is arranged in the fixed box. According to the device, the zinc oxide arrester resistance current tester is lifted, and the tester can be smoothly, safely and stably lifted to the position to be measured.

Description

technical field [0001] The invention relates to the technical field of arrester testing, in particular to a lifting device for a zinc oxide arrester resistive current tester. Background technique [0002] The arrester resistive current tester is a special instrument for comprehensively testing the electrical characteristics of the zinc oxide arrester in the power system operation. It has the advantages of fast calculation, safety and reliability. It is a special instrument for testing the electrical performance of the zinc oxide arrester. Various voltage levels of zinc oxide surge arresters live or power outage detection, so as to timely discover dangerous defects such as moisture in the internal insulation of the equipment and valve aging, and has the characteristics of fast calculation speed, safety and reliability. [0003] At present, when using the arrester resistive current tester, the operator needs to manually carry the tester to climb to the triangular ladder, and t...
