Multi-gap ground wire insulator

Abstract

The invention relates to the technical field of insulators, in particular to a multi-gap ground wire insulator which comprises an insulator body, a steel cap, a steel pin, an upper electrode and a lower electrode. The steel cap and the steel pin are respectively arranged at the top and the bottom of the insulator body; the first end of the lower electrode is detachably connected with the steel pin, and the second end of the lower electrode extends outwards; the upper electrode comprises an upper electrode hoop and a plurality of upper electrode pins; the upper electrode hoop is detachably connected to the steel cap in a sleeving manner; the plurality of upper electrode pins are uniformly distributed on the upper electrode hoop in a central radial manner; the first end of each upper electrode pin is connected with the peripheral wall of the upper electrode hoop; and the second end of each upper electrode pin extends outwards to form a discharge gap with the lower electrode. According to the ground wire insulator, the technical problem that the normal use of the insulator is affected due to the fact that the upper electrode and the lower electrode of the existing ground wire insulator are easy to deviate is effectively solved.

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 released 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 ele...
