Into inlet wire interval.Generally there is transformer bay every, bus interval, capacitor standoff etc..All new are spaced in build completion
After be required for carrying out an acceptance inspection and can just come into operation.
Need to complete remote control transmission test when transformer station's expansion spacing is checked and accepted, remote control refers to by the local backstage electricity of transformer station
Brain or Dispatching monitor and control system assign point/and reclosing command realizes the technology an of distant place point/combination switch or disconnecting link.This is modern automation
One of prerequisite technical requirements of transformer station.The problem of such can be run into the actual course of receiving：Bus charging operation, it is impossible to
Actual division disconnecting link.It like this can not conventionally complete to be remotely controlled transmission test.But simulation can be passed through
The method of measurement completes the checking of remote control circuit, and simply disconnecting link in itself and is failure to actuate.Specific implementation process is as follows：It is remotely controlled separating brake
When, it is necessary to which four people coordinate, a people operates on monitoring computer indoors, assigns telecommand, its excess-three people is at switch mechanism case
Share out the work and help one another：One people closes position signal terminal with cable core short circuit signal common port and disconnecting link, and position is closed to simulate disconnecting link；One people uses
The break-make shelves of universal meter measure remote control circuit, and in the moment that telecommand is assigned, remote control circuit conducting, universal meter can be sent " serge "
A sound, the sound of " serge " can not be heard if remote control circuit is incorrect；Also a human hand held intercom is assigned distant with interior
Control the personnel, talking of instruction.When being remotely controlled separating brake, open position is at because disconnecting link is actual, therefore is not required to simulate disconnecting link position letter
Number, a people can be saved.The conducting in a flash only assigned due to loop in guidance command, it is therefore desirable to which owner's tacit agreement coordinates ability
Complete once remote control experiment.It is responsible for whole process when simulation disconnecting link closes people's short-circuited terminal of position and can not have a little to relax, otherwise can be due to
Flashing for disconnecting link position causes remote control to fail.It is intended to again due to backstage, homophony, for five tune, D5000, special line monitoring systems distant
Control once, therefore completion one is very time-consuming whole remote controls of disconnecting link, and the operation difficulty of whole process is larger, and expense of taking a lot of work
When, operating efficiency is very low.
The content of the invention
The purpose of this utility model is to provide a kind of manpower, improves adjustable short circuit piece of operating efficiency.
To achieve the above object, the utility model employs following technical scheme：A kind of adjustable short circuit piece, including it is short
Contact pin unit and the insulation shell being wrapped in outside short circuit blade unit, short circuit blade unit include the first short circuit piece and the second short circuit piece,
The length direction arranged for interval of first short circuit piece, the second short circuit piece along insulation shell, the first short circuit piece and the second short circuit piece are each other
Remote end is separately provided for the connecting pole of connection terminal row, and the first short circuit piece and the second short circuit piece are close to each other
End is respectively arranged with connecting hole, and insulation shell is provided with the breach for being used for appearing connecting hole, the first described short circuit piece and the
Two short circuit pieces are attached by transition connection sheet, and the both ends of transition connection sheet are respectively arranged with connecting pin, transition connection sheet
Outside is coated or is enclosed with insulating barrier, and transition connection sheet is placed on insulation shell, and connecting pin is plugged in connecting hole through breach,
First short circuit piece, the second short circuit piece, connecting pole, transition connection sheet and connecting pin are made by conductive material.
Due to being plugged on the first short circuit piece, second respectively using the connecting pin of above technical scheme, transition connection sheet both ends
In connecting hole on short circuit piece, three is linked to be an electric conductor, then by the connecting pole on the first short circuit piece and the second short circuit piece
Position signal terminal is closed with signal common port and disconnecting link to be connected, position is closed so as to realize that simulation disconnecting link is in respectively.The utility model is used
Short circuit piece replaces artificial short-circuiting cable cored wire short circuit signal common port to close position signal terminal with disconnecting link, saves manpower.And short circuit
Piece is higher compared to the stability of manpower short circuit, and error rate is smaller, so as to further increase operating efficiency.
