Abstract

The invention discloses method and special tool for the live replacement of a zinc oxide lightning arrester. In the operation method, an insulated sling hook and a special tool are used to insert the special tool into a rectangular hanging plate connected with a ball socket, a flat part is used to support the ball socket and control the ball socket to separate from the zinc oxide lightning arrester. Aiming at the traditional ground potential live replacement of a zinc oxide lightning arrester of an overhead transmission line, the operation tool and the operation method can lighten the labor intensity of working stuff and improve the working efficiency and are simple and safe.

Description

The method of charged for replacement zinc oxide arrester and specific purpose tool
Technical field
The present invention relates to a kind of replacing zinc oxide arrester, particularly a kind of method of charged for replacement zinc oxide arrester, and the specific purpose tool that is used to change zinc oxide arrester.
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.
Summary of the invention
The object of the present invention is to provide a kind of method of charged for replacement zinc oxide arrester.
Another object of the present invention also 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 method of charged for replacement zinc oxide arrester, (1) utilize the insulated sling hook to catch on the synthetic insulator that is connected with zinc oxide arrester, and the insulated sling hook is fixed on the iron tower, (2) utilize the insulating bar splitting that zinc oxide arrester is connected the bowl head with synthetic insulator spring catch is taken out, (3) specific purpose tool is inserted the right angle link plate that is connected with the bowl head, utilize flat oral area position to support the bowl head, control bowl head breaks away from zinc oxide arrester.
This operational method is at the earth potential live replacing of present aerial power transmission line zinc oxide arrester, and is simple and safe.Adopt the operational method of this charged for replacement zinc oxide arrester, equipotential on year-on-year basis operational method can reduce operating personnel 2~3 people, shortens about 40 minutes of activity duration.Can reduce the labour intensity of operating personnel on the bar effectively, improve whole operating efficiency.Have stronger practicality and popularizing application prospect widely.
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, the invention has the advantages that:
This power tool and operational method can reduce intensity of workers at the earth potential live replacing of present aerial power transmission line zinc oxide arrester, increase work efficiency, and be simple and safe.
