Description
Technical field
Power supply unit maintenance auxiliary tool is the utility model is related to, more particularly to a kind of 110kV and above arrester are counted
Device live replacing device.
Background technology
Counter of lightning arrester is widely used on 110kV and above arrester, and counter is connected on arrester bottom, is used for
Lightning arrestor movement number is recorded, the change by observing follow current can effectively detect that arrester is internal aging, makes moist
It is abnormal, open air is generally installed on, running environment is consistent with arrester, therefore the failure rate of counter of lightning arrester is very high, works as hair
It must be replaced during raw damage.
When circuit charging operation, the current potential that arrester tail end has comparison high is grounded by counter of lightning arrester, the current potential
Increase with voltage class and increase, if dismounting counter, floating potential directly discharge over the ground in circuit operation, operation can be caused
Personnel get an electric shock, and to ensure operating personnel's personal safety, thus conventional counter is replaced and is typically necessary line outage, greatly shadow
The power supply reliability of transmission line of electricity is rung.
Utility model content
In view of this, the purpose of this utility model is to provide a kind of 110kV and above counter of lightning arrester charged for replacement dress
Put, easy for assemble or unload, the strong applicability of counter.
The purpose of this utility model is achieved through the following technical solutions：
A kind of 110kV and above counter of lightning arrester live replacing device, including two magnetic supports, the company of being provided with the magnetic support
Block is connect, terminal is provided with the contiguous block, a conducting wire both ends are arranged on two contiguous blocks by terminal respectively, institute
State and handle is additionally provided with contiguous block, magnetic support switch is provided with the magnetic support.
Further, the handle is rotatably provided on contiguous block.
Further, the handle includes horizontal part and vertical portion, its vertical portion is vertically set on contiguous block.
Further, the contiguous block is bar shaped, and its one end bottom is fixed on magnetic support top, and terminal is arranged on company
Connect on the block other end.
Further, the conducting wire uses the 25mm of crust insulation2Multiply is grounded annealed copper wire.
The beneficial effects of the utility model are：
A kind of 110kV and above counter of lightning arrester live replacing device of the utility model, when magnetic support, which switchs, to be opened,
Magnetic support is adsorbed on the band iron at counter both ends by portable handle, device short circuit counter, thus can powered dismounting keep away
Thunder device counter, without have a power failure, do not influence power supply reliability, counter it is easy for assemble or unload.
Other advantages, target and feature of the utility model will be explained in the following description to a certain extent
State, and to a certain extent, based on will be apparent to those skilled in the art to investigating hereafter, or
Person can be instructed from the practice of the utility model.The target of the utility model and other advantages can be said by following
Bright book is realized and obtained.
Brief description of the drawings
In order to make the purpose of this utility model, technical solution and advantage clearer, below in conjunction with attached drawing to this practicality
It is new to be described in further detail, wherein：
Fig. 1 is the utility model structure diagram.
Embodiment
Hereinafter reference will be made to the drawings, and the preferred embodiment of the utility model is described in detail.It is it should be appreciated that it is preferred that real
Example is applied only for illustrating the utility model, rather than in order to limit the scope of protection of the utility model.
As shown in Figure 1, a kind of 110kV and above counter of lightning arrester live replacing device, including two magnetic supports 1, on magnetic support 1
Contiguous block 3 is provided with, contiguous block 3 is bolted on magnetic support 1, and terminal 4,5 liang of a conducting wire are provided with contiguous block 3
End is detachably arranged on two contiguous blocks 3 by terminal 4 respectively, and handle 6 is additionally provided with contiguous block 3, is set on magnetic support 1
There is magnetic support to switch 2, OFF grades and ON grades are labeled with switch 2, when adjusting to ON grades, magnetic support has adsorption capacity, wherein ON gears magnetic
Seat can produce 30kg adsorption capacities and reliably be adsorbed on ground connection band iron；OFF gears can be convenient to remove the present apparatus by magnetic support demagnetization,
Preferably, two faces of magnetic support can produce adsorption capacity.
Handle 6 is rotatably provided on contiguous block, it can be applicable to diverse location in the rotation of 360 ° of 1 upper surface of magnetic support
The dismounting of counter, it is easy to use.
Handle 6 includes horizontal part and vertical portion, its vertical portion is vertically set on contiguous block, its vertical portion end passes through spiral shell
Nail is arranged on contiguous block.
Contiguous block 3 is bar shaped, and its one end bottom is fixed on the top of magnetic support 1, and terminal 4 is arranged on the contiguous block other end
On.
The 25mm that conducting wire 5 is insulated using crust2Multiply is grounded annealed copper wire, can ensure that the reliability of ground connection.
Counter of lightning arrester charged for replacement mode is：Two magnetic supports 1 are switched and switch to ON grades, magnetic support 1 produces magnetic force,
Operating personnel holds handle 6 and two magnetic supports 1 is adsorbed on the band iron 8 at counter of lightning arrester both ends respectively, and arrester passes through magnetic
Seat 1, contiguous block 3, terminal 4,5 reliable ground of conducting wire, remove counter and consolidate successively after at the same time counter is shorted
Determine bolt, after the completion of replacing refresh counter, hold handle 6 two magnetic supports 1 are switched 2 respectively and switch to OFF grades, 1 demagnetization of magnetic support, i.e.,
The covering device can be unloaded.
Finally illustrate, above example is merely intended for describing the technical solutions of the present application, but not for limiting the present application, although ginseng
The utility model is described in detail according to preferred embodiment, it will be understood by those of ordinary skill in the art that, can be to this
The technical solution technical scheme is modified or replaced equivalently of utility model, without departing from the objective and scope of the technical program, it should all
Cover among the right of the utility model.
