A multi-gap ground wire insulator

Abstract

This application relates to the technical field of insulators, in particular to a multi-gap ground wire insulator, including an insulator body, a steel cap, a steel foot, an upper electrode and a lower electrode; bottom; the first end of the lower electrode is detachably connected to the steel foot, and the second end of the lower electrode extends outward; the upper electrode includes an upper electrode hoop and a plurality of upper electrode pins; the The upper electrode hoop is detachably sleeved on the steel cap; a plurality of the upper electrode pins are evenly distributed on the upper electrode hoop in a radial shape in the center; the first end of each upper electrode pin is connected to the upper electrode pin The outer peripheral wall of the upper electrode hoop is connected; the second end of each upper electrode pin extends outward and forms a discharge gap with the lower electrode. The application effectively solves the technical problem that the upper and lower electrodes of the existing ground wire insulator are prone to offset, thereby affecting the normal use of the insulator.

Description

technical field [0001] The present application relates to the technical field of insulators, in particular to a multi-gap ground wire insulator. Background technique [0002] The ground wire insulator insulates the ground wire from the iron tower, mainly composed of insulating parts and gaps, and has the functions of reducing the energy consumption of the ground wire and overvoltage discharge. The standard JB / T9680-2012 "Insulators for Ground Wires of High-Voltage Overhead Lines" stipulates that "the electrodes should be easy to assemble, the ring of the lower electrode should be forged as a whole, and the relative position should be accurate. The gap distance should be adjusted at 10-30mm, and it should not be loose after fixing. , the fastening bolts and nuts should not be tripped under the torque of 50N·m". [0003] At present, the gap between the ground wire insulators is made of galvanized steel sheets or galvanized steel strips to form claw electrodes. The upper elec...
