Description
Technical field
A kind of electric power hotline maintenance instrument is the utility model is related to, i.e., R type spring pins at 66kV straight line poles bowl head
Current potential plug device.
Background technology
In the prior art, with the high speed development of smart power grid power transmission line, it is desirable to which Condition-based Maintenance of Transmission Line is carried out
Livewire work service work.Livewire work service work does not influence the normal operation of system, it is not necessary to grid switching operation, it is not necessary to changes
Become the method for operation, therefore power failure will not be caused to power more, improve the economic and social benefits.
At present because the updates such as transmission line equipment gold utensil are very fast, new equipment gold utensil does not have special livewire work
Instrument, lead to not carry out livewire work, brought to actual power generation, maintenance and service work constant.66kV straight line poles
For insulator such as situations such as daily sampling observation, rotation, thunderbolt, earth potential live replacing insulator is routine work project.Powered work
Industry changes insulator, it is necessary to carries out ground potential using special isolation instrument and removes between connecting insulator and side of wire socket-clevis eye
Spring pin（See Fig. 2）, insulator is departed from socket-clevis eye, insulator could be removed, special isolation work is recycled after replacing
Tool installation spring pin recovers the connection of insulator and socket-clevis eye.
The spring pin form between insulator and socket-clevis eye has two kinds at present：
W type spring pins（Abbreviation W type pins）The commonly used pin type of current power transmission circuit, such pin easily go out
Situations such as being now broken, flying off, W type pins have special isolation instrument to carry out powered plug work, and working system work is simple and convenient.
R types spring pin is relatively conventional in newly-built circuit at present, and Bai Shan electric companies have not occurred pin since applying 10 years
Failure, stability are high, and without extract completely during work, need to only extract 3.2cm can carry out insulator and depart from more to change jobs, but by
In R type spring pins just put into recent years in actual production work, no specific purpose tool carries out powered plug work.
Because carrying out plug without specific purpose tool, this is to the day-to-day operation of transmission line of electricity, maintenance, maintenance and changes insulator
Work brings inconvenience.
There is no special powered plug work to the insulator using the connection of R types spring pin to solve 66kV transmission lines of electricity
Tool, can not carry out the situation of livewire work, be the problem of we are in the urgent need to address,
Utility model content
The purpose of this utility model is to provide R type spring pins at a kind of 66kV straight line poles bowl head for above-mentioned deficiency
Ground potential plug device, realizes powered plug R type spring catch, and R type spring catch plug length is controllable.
Technical solution of the present utility model is：R types spring pin ground potential plug device at 66kV straight line pole bowl heads,
It is characterized in that including a quadrilateral frame, each arm side junction is movably hinged, between two-arm side joint is corresponding（On a left side
Right two pairs of arm rooms）Through leading screw is threaded with, leading screw outer end is connected with insulating bar, is revolved above quadrilateral frame plane and is set pin
Bar, pin rod one end are connected by vertical rod with two arm side pin joints on the left of quadrilateral frame, and pin rod other end band is downwardly into R types
Drag hook in the exposed circle head of spring pin, carries gap shape bowl head neck on the left of quadrilateral frame at two arm side pin joints.
There is positioning screw cap on leading screw in quadrilateral frame, it is 4mm that limitation, which pulls out R type spring pins stroke,.Positioning screw cap
There are 2, effect is all to ensure that plug device energy horizontal ends are steady, prevents plug device from operating inconvenience caused by rotation.
Plug device coupler body is hooked R type spring pins, the base of two isoceles triangles in left and right is adjusted by rotary screw
To be lifted and falling head, reach plug pin so as to increase or decrease stroke.It is the principle using isosceles triangle,
In isosceles triangle, base length and the high line of triangle are inversely proportional.
According to State Grid Corporation of China《Live line tool technical requirements and Guidance Rule》（GB/T18037-2000）、《Electricity
Power safety work order》Circuit pack（Q/GDW1799.2-2013）、（GB/T25318-2010）《String insulator unit ball nest joins
Connect and use locking pin size and experiment》、《The electric armour clamp handbook third edition》（China Electric Power Publishing House's Dong Ji straightforward words）Technical requirements and
On-site actual situations, this product should ensure that metal part weight is not more than 2kg, and insulated part insulated lengths meet 66kV:1m's
Effective insulated lengths requirement.Because R types spring pin does not have to extract completely, it is 4cm that only pin need to be extracted into haul distance（Leave
Adjustable remaining）.
The utility model has the advantages that：Quadrilateral frame is pulled using leading screw, drives pin rod to realize and moves horizontally, Ke Yifang
Just control outside R types spring pin and draw distance, both do not fell off, can conveniently dismantle insulator, simple to operate, making maintenance side again
Just, and can solve laborious problem by insulating bar increase rotating lever.
Embodiment of the present utility model is described in further detail below in conjunction with accompanying drawing.
Brief description of the drawings
