Abstract
The utility model discloses a special tool for electrified replacement of zinc oxide arresters, which comprises an insulating rod and a working head, wherein the working head comprises a flat opening part and a third support rod, wherein the flat opening part is formed by a first support rod and a second support rod which are positioned in the same plane and are arranged in parallel, the third support rod is positioned right below the plane and extends in the same direction of the first support rod and the second rod, the third support rod is connected with the fixed ends of the first support rod and the second support rod, and the working head is detachably and movably connected with the insulating rod. The operating tool aims at the electrified replacement of the zinc oxide arresters of the existing overhead power transmission line at a ground potential, can reduce the labor intensity of working staffs and improve the working efficiency, and is simple and safe.
Description
Technical field
The utility model relates to a kind of replacing zinc oxide arrester, particularly a kind of charged for replacement zinc oxide arrester specific purpose tool.
Background technology
In recent years; for strengthening the overhead transmission line lightning protection; reduce lightning strike accident; the serious regional overhead line structures of part damage to crops caused by thunder have been installed zinc oxide arrester; for solving under the situation that does not influence the power transmission sequence operation; the problem of data is tested, collected to the zinc oxide arrester that uses the regular period, the method for the on-the-spot earth potential live replacing zinc oxide arrester that is suitable for of a cover need be provided and change required instrument.
The utility model content
The purpose of this utility model is to provide a kind of light, as to meet the charged for replacement zinc oxide arrester of work on the spot place safety condition requirement specific purpose tool of operating.
A kind of specific purpose tool of charged for replacement zinc oxide arrester, comprise insulating bar, working head, described working head comprise be positioned at flat oral area conplane, that constitute by two first, second parallel struts and be positioned under this plane, constitute along the 3rd support bar that equidirectional extends with first and second strut, described the 3rd support bar is connected in the stiff end of first and second strut, is dismountable flexible connection between working head and the insulating bar.
In when work, the working head of specific purpose tool is connected on the insulating bar, then utilize specific purpose tool to insert the right angle link plate that is connected with the bowl head, utilize flat oral area position to support a bowl head, control bowl head and zinc oxide arrester disengaging.
Described the 3rd support bar is the support bar of " L " shape.
Detachable flexible connection between described working head and the insulating bar or for being threaded or being connected for bolt-type.
Described insulating bar or for telescopic insulating bar or for changing the insulating bar of length.
The structure of telescopic insulating bar has a lot, below is two kinds of forms that the applicant provides:
A kind ofly be: telescopic insulating bar is made of the insulated tube of more piece, and the insulated tube of more piece is sleeved on together layer by layer, between the insulated tube of mutual sheathing or adopt and be threaded, or adopts latch to connect.
During use, can launch the insulated tube of different joint numbers as required.
Two kinds are: described telescopic insulating bar is that the insulated tube of the suit layer by layer with tapering of more piece constitutes.
The described insulating bar that changes length constitutes for the insulating bar by more piece, adopts dismountable flexible connection between each insulating bar.
Dismountable flexible connection between described each insulating bar is threaded, or is the bolt-type connection.
In sum, advantage of the present utility model is:
This power tool can reduce intensity of workers at the earth potential live replacing of present aerial power transmission line zinc oxide arrester, increases work efficiency, and is simple and safe.
