Description
Technical field:
Pulled back swing arm short circuit earthing clamp and ground connection and method for dismounting the present invention relates to one kind.
Background technology:
At present, existing short-circuit grounding wire is made up of wire clamp, ground wire, earth clip etc..During line maintenance, to prevent from missing
Power transmission, other branch roads fall power transmission or induced voltage etc. must just install temporary short-circuit ground wire to the person or the injury of equipment.But
It is that traditional duckbilled impacting type earthing clamp is the supporting post-rod in the own wt slamming down wire clamp using wire clamp and is allowed to de-
Elastic force from support release torsion spring clamps wire.Because ground wire is longer, thicker own wt be much larger than the weight of wire clamp, to
Not enough, wire clamp inner support push rod can not depart from support to lower punch power, and some install pouring weight additional in wire clamp both sides clamping plate, and which increase wire clamp
Deadweight, improved effect is not also obvious.The interference of wind-force often makes wire clamp duckbilled dehisce that wire, increase dress can not accurately be directed at
If difficulty.Also the drainage thread of angle tower interior angle side below cross-arm due to that can not install.
In order to overcome the drainage thread of difficult existing ground wire installing, wind-force interference and angle tower interior angle side not it is horizontal but under
The problem of Fang Buneng is directly installed, the present invention provides a kind of novel conductive wire wire clamp, and the wire clamp is on the basis of existing wire clamp form
Increase a swing arm of pulling back, make the duckbilled that wire clamp opens be changed to be pulled back up motion by moving downward, can be achieved simply, easily
Install, do not disturbed by wind-force, it is to avoid Danger Electric shock risk on the drainage thread of tangent tower wire and angle tower interior angle side.
The content of the invention:
Pulled back swing arm short circuit earthing clamp it is an object of the invention to provide one kind, be related to high pressure and super, extra-high voltage electric power line
The short-circuit grounding wire wire clamp on road, can especially overcome traditional wire to clamp and set difficulty, easily disturbed and can not directly existed by wind-force
The short circuit earthing clamp installed on the drainage thread of angle tower interior angle side.
Above-mentioned purpose is realized by following technical scheme:
1. the present invention is simple to operate, quick and can not installed in drainage wire in the angle tower interior angle side of horizontal but lower section, no
Disturbed by wind-force, it is to avoid Danger Electric shock risk.Pulled back pendulum using a metal J-type being connected through the hinge with wire clamp side clamping plate
Arm, changes the application point to the pulling force of wire clamp, realizes and vertically, is laterally filled in the mode of pulling back, tears operation open.Line is replaced with pulling force
Folder deadweight triggering wire clamp, is not being influenceed and wind-force is disturbed by ground connection line length, is adapted to each high pressure, super(It is special)High pressure level
Circuit.
The present invention designs a swing arm of pulling back on the basis of existing wire clamp form, wire clamp is in hook-type state of pulling back, by
The pulling force of people replaces gravity, and so pulling up wire clamp by operating personnel just can easily install short-circuit grounding wire.Return
It is that an one end is connected by hinge with wire clamp side clamping plate to draw swing arm, the J-type aluminium alloy casting hook of opposite side dead earth line
Part.When installing ground wire, first swing arm is rotated to duckbilled direction, until swing arm and clamping plate side are combined, firmly separated wire clamp duck
Mouth(Both sides clamping plate), meanwhile, swing arm card face is also blocked by the clamping plate top surface of wire clamp opposite side, and hook-type state of pulling back just is presented in wire clamp
.Then, wire clamp is placed in below wire, the de- branch of the supporting post-rod being pulled upwardly in insulating cord or ground wire, wire clamp, which is clamped, to be led
Line, is installed successfully, meanwhile, the top surface of wire clamp clamping plate loses the clamping lock effect to swing arm card face, and swing arm is swung back rapidly upward, makes line
Lower turn of duckbilled direction is pressed from both sides, secondary pulling insulating cord or ground wire, wire clamp are just disassembled.
The present invention is used for the short circuit grounding of high-voltage electric power circuit, can overcome installing difficulty, not by wind-force interference and in corner
Install tower interior angle side.It is one swing arm of pulling back of design on existing wire clamp, wire clamp is in hook-type state of pulling back, by the pulling force of people
Instead of gravity impact wire, wire clamp is pulled to fill, tear open.Swing arm of pulling back is that an one end passes through hinge and wire clamp side clamping plate
Connection, the J-type aluminium alloy casting hook of opposite side dead earth line.Swing arm of pulling back changes the application point of pulling force suffered by wire clamp,
Realize and vertically, laterally filled in the mode of pulling back, tear operation open.
