Description
Technical field
The present invention relates to a kind of high-voltage earthing line apparatus, more particularly to for the hanging-connecting of 66kV and 220kV voltage class
Ground wire, belongs to power system security Work tool field.
Background technology
In power system, ground wire is to prevent work when unexpectedly there is voltage in the equipment and circuit having had a power failure
Make personnel's electric shock, mounting and to remove ground wire be to stop one of necessary step in power transmission operation is most important for production safety,
Can ground wire mounted just turns into a necessary condition for ensureing safety in production.And existing high-voltage grounding wire and insulating bar are as schemed
Shown in 1 and Fig. 2, including 1 annulus connects 3 earth leads in the side of 4 grounding wire connectors, 2 ground wire connecting sleeve pipes and 4 ground wires connect
Head, 5 spring clipes are inside 4 grounding wire connectors, ground wire plug special is chosen in 6 metal joints connection 8 and 9 insulation stocks, 7 slippage states
Hand, 10 insulation retaining rings.There is following deficiency in existing ground wire：
During the wire of eminence is sandwiched 5 spring clipes by purpose during mounting ground wire, due to the side only one of which of 4 grounding wire connectors
1 annulus, when 4 grounding wire connector is mounted on wire, 8 choose ground wire plug special and are through 1 annulus the inside on insulating bar, by ground wire
Head height is hung on wire after lifting, but during 8 choose ground wire plug special and can be rotated in 1 annulus so that 4 grounding wire connectors
On 5 spring clipes cannot vertically downward be directed at wire, when staff drags insulating bar downwards, 4 grounding wire connectors just cannot
Easily by conductor grip in 5 spring clipes wherein, and repeatedly in cut-and-try process, 4 grounding wire connectors are easy to choose ground wire from 8 special
With in plug slide, the equipment and the safety of staff below high-altitude are threatened, remove ground wire when problem similarly.
The content of the invention
It is an object of the invention to provide high-voltage earthing line apparatus simple and easy to apply when a kind of simple structure, mounting and dismounting,
The grounding wire device can be eliminated when mounting and removing ground wire to equipment and the potential safety hazard of the person.
In order to solve the problems, such as prior art, the technical solution adopted by the present invention is：
High-voltage earthing line apparatus, include dicyclic earth terminal and insulating bar, and described dicyclic earth terminal includes N-shaped
Ground wire hanging joint, one end of ground wire hanging joint is connected with ground wire wire by ground wire connecting sleeve pipe, is set inside ground wire hanging joint
Spring clip is equipped with, the side that ground wire hanging joint is connected with ground wire connecting sleeve pipe is provided with two annulus；
Described insulating bar includes metal joint, is connected with the top of metal joint and chooses ground wire plug special, metal joint
Bottom is connected with insulation stock, two connection-pegs be provided with ground wire plug special in described are chosen, positioned at the connection-peg at top
Length is longer than the length of the connection-peg positioned at bottom.
The afterbody of described insulation stock is provided with insulation handle, and insulation is provided between insulation handle and insulation stock
Retaining ring.
Advantage for present invention is with effect：
When mounting and removing ground wire, insulating bar double-inserting type joint can be very good control to high-voltage earthing line apparatus of the present invention
The angle of earth connection point and electric wire, staff can preferably control electric wire in the underface of spring clip, and bicyclic
Structure can ensure that earth connection point will not rotate, and in drop-down insulating bar, easily can hang on electric wire earth connection point very much.
And be also prevented from the long rear monocyclic lateral rotation of use time and be not on a horizontal plane with ground wire hanging joint.Dismounting connects
During ground wire, plug above is first penetrated the circular hole above earth connection point by insulating bar double connection-pegs sample different in size, is then being worn
Another plug, now earth connection point and insulating bar have become an entirety, above push away insulating bar and just can be very good to remove
Ground wire.The top edge of irregularly-shaped hole above uses triangular design, coordinates the use of hook connection-peg, can effectively prevent
When only holding earth connection point high, ground wire slides, and smashes device and charging equipment, injures the events such as staff by a crashing object.Ground wire is being installed
When, the lower edge of underlying irregularly-shaped hole uses triangular design, is engaged with lower hook-type connection-peg so that ground wire can be with short
Time is fixed on insulating bar, is installed more laborsaving.When ground wire is dismantled, the top edge of irregularly-shaped hole above is adopted
It is engaged with upper hook-type connection-peg with triangular design, so that remove the simpler reliability of ground wire.Because irregularly-shaped hole is by triangle
Shape, rectangle and semicircle composition, hole is expanded, plug is easier insertion.The present invention is simple and reasonable for structure, greatly
The demand for meeting power system operation of limit.
