A special insulating hanger for equipotential replacement tensile monolithic insulator

Abstract

The invention provides a special insulating hanger for equipotential replacement tensile monolithic insulator, which comprises a support seat, a limit rotating hanger rod and a front splint. A supportseat comprises a cylindrical base, a bar plate, a rotating limit inner groove is arranged on that cylindrical base, the bar plate extends transversely along the middle of the cylindrical base, the whole is inclined downward, the end of the bar plate is bent into an arc-shaped bayonet, and the arc-shaped bayonet is provided with a perforation; A limiting rotary suspension bar comprises a column vertical bar and an extension plate, wherein that column vertical bar is insert into a cylindrical base, and is inserted and matched with a rotary limiting slot through a limiting pile; Under the cooperation of the limit pile and the rotation limit slot, the column vertical bar can realize the horizontal 90 degree limit rotational cooperation with the cylindrical base. An extension plate is arrangedat the upper end of the column-shaped vertical bar, which is an inverted L-shaped plate, and a front splint is arranged at the end of the extension plate downward. The invention has the advantages ofgood operation safety, effective improvement of working efficiency and operation safety, and the lifting of the fixture and the monolithic insulator can be realized by cooperating with the insulationelectrodeless rope and the special sling of the fixture.

Description

technical field [0001] The invention relates to the technical field of electric power operation, in particular to an insulating hanger special for equipotential replacement of tension-resistant single-piece insulators. Background technique [0002] 220KV live (equal potential) replacement of single-piece tension insulators is the most common work in live work of 220KV transmission lines. In order to meet the safety of live work, before the number of failed insulators in the whole string of insulators does not reach the number required by regulations, they should be replaced in time. Under normal circumstances, personnel are organized to replace the failed insulators of the entire line in combination with the line outage plan, but the workload of the operators has not been reduced. [0003] At present, in the conventional 220KV electrified (equal potential) replacement of tension-resistant single-piece insulators, it is necessary to lift the fixture and single-piece insulato...

AI Technical Summary

Problems solved by technology

[0004] After long-term experience verification, the above-mentioned operation method has many shortcomings: on the one hand, the equipotential operation hand sits on the insulator to operate, and the stability coefficient is not high; The electric potential operator increases a lot of physical exertion; on the other hand, the safety of the operation cannot be guaranteed, which puts forward higher requirements for the overall quality of the electric potential operator
