Hand, 10 insulation retaining rings.Following deficiency be present in existing ground wire：
Purpose sandwiches the wire of eminence in 5 spring clipes during mounting ground wire, because the side of 4 grounding wire connectors only has
One 1 annulus, toward when mounting 4 grounding wire connector on wire, 8 choose ground wire plug special and are through inside 1 annulus on insulating bar, will
Ground wire is hung on wire after holding high, but during 8 choose ground wire plug special and can be rotated in 1 annulus so that 4 ground wires
5 spring clipes on joint cannot be directed at wire vertically downward, and when staff drags insulating bar downwards, 4 grounding wire connectors are 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 from 8
Slid in line plug special, the equipment below high-altitude and the safety of staff are threatened, problem is same when removing ground wire
Reason.
Utility model content
A kind of the purpose of this utility model high-voltage earthing simple and easy when being to provide simple in construction, mounting and removing is traditional thread binding
Put, 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 that prior art is present, the technical solution adopted in the utility model is：
High-voltage earthing line apparatus, includes dicyclic earth terminal and insulating bar, and described dicyclic earth terminal includes
There is the ground wire hanging joint of n-type, one end of ground wire hanging joint is connected by ground wire connecting sleeve pipe with ground wire wire, in ground wire hanging joint
Portion is provided with spring clip, and ground wire hanging joint is provided with two annulus with the side that ground wire connecting sleeve pipe is connected；
Described insulating bar includes metal joint, is connected with the top of metal joint and chooses ground wire plug special, and metal connects
The bottom of head is connected with insulation stock, and described choosing is provided with two connection-pegs, the grafting positioned at top on ground wire plug special
The length of head 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 possessed by the utility model is with effect：
For the utility model high-voltage earthing line apparatus when mounting and removing ground wire, insulating bar double-inserting type joint can be very
Good control earth connection point and the angle of electric wire, staff can preferably control electric wire in the underface of spring clip, and
And bicyclic structure can ensure that earth connection point will not rotate, when pulling down insulating bar, very easily earth connection point can be hung
On electric wire.And it is also prevented from the long rear monocyclic lateral rotation of usage time and a horizontal plane is not in ground wire hanging joint
On.When removing ground wire, the double connection-pegs of insulating bar sample different in size, the circle for first penetrating plug above above earth connection point
Hole, another plug then is being worn, now earth connection point and insulating bar have become an entirety, above push away insulating bar can
Ground wire is removed well.The top edge of irregularly-shaped hole above uses triangular design, coordinates the use of hook connection-peg,
When effectively can prevent from holding high earth connection point, ground wire slides, and smashes device and charging equipment, injures the events such as staff by a crashing object.
During installation ground wire, 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 fixed on insulating bar with the short time, installed more laborsaving.When dismantling ground wire, irregularly-shaped hole above
Top edge be engaged using triangular design with upper hook-type connection-peg so that it is simpler reliable to remove ground wire.Due to abnormity
Hole is made up of triangle, rectangle and semicircle, expands hole, makes plug be easier to insert.The utility model structure
Simply, rationally, greatly meets the needs of power system operation.
