Problems solved by technology

The main problems faced by the live work of the ground pole overhead line: when replacing the suspension insulator of the ground pole line, the diameter of the ground pole insulator is large and the slot is deep, and it is time-consuming and laborious to operate it with the existing insulation operation tools
This invention is suitable for the operation of the switch on the pole and the isolation switch, as well as the switching operation of the substation, but it is not suitable for the live replacement operation of the suspension insulator of the ground electrode line

Abstract

The invention discloses an insulating rod for shortening the working time for electrified replacement of a suspension insulator of a ground electrode, which comprises a C-shaped elbow, a support plate, a force applying device, a pin puller, a rod body and an operating mechanism. The C-shape elbow is arranged at the top end, and the upper and lower ends of the opening are provided with inclined surfaces; the support plate is arranged below the C-shaped elbow; the force applying device is arranged in front of the support plate; the pin puller is arranged on the upper part of the front side of the force applying device; the rod body is arranged below the support plate; the operating mechanism is arranged at the lower part of the rod body. The insulating rod is capable of pulling and pluggingpins and removal and restore insulator connection, and the working time of electrified replacement of the grounding line suspension insulator is greatly shortened, the working time of high-altitude work is reduced, and the physical strength is saved.

Description

technical field [0001] The invention belongs to the technical field of power grid maintenance, and in particular relates to an insulating rod for shortening the working time of live replacement of a ground electrode suspension insulator. Background technique [0002] The ground electrode line is an important part of the UHV DC transmission system. It is an overhead line connecting the neutral bus of the converter station and the ground electrode diversion system. It has the characteristics of large current and low voltage. Both ends of each DC transmission line are connected There are grounding electrode overhead lines, if the grounding electrode line fails, it will directly affect the safe operation of the UHV DC transmission line. The main problem faced by the live work of the ground pole overhead line is that when replacing the ground pole line suspension insulator, the ground pole insulator has a large diameter and deep slots, and it is time-consuming and laborious to op...
