In addition, now the 10kV distribution line has been extensive use of insulated conductor, and during the operation of insulated conductor earth potential live, operating personnel use earth potential insulated conductor peeler to divest insulating barrier earlier, will go between with traditional hook of starting to exchange fire and lead links together again.
Because the specifications and models of homemade insulated conductor are not exclusively unified, thickness of insulating layer is inhomogeneous, and also has the double hyer insulation layer in the insulated conductor that uses, so peeler is in use operated very difficult even can't be used, and damage wires very easily, existing earthing clamp is provided with clamp, clamp is provided with groove, the following trough rim of groove is provided with through hole, be provided with pull bar in the through hole, be provided with ambulatory splint in the groove, ambulatory splint is connected with pull bar, pull bar and ambulatory splint link are with spring, the other end is provided with blocking cap and connection handle, correspondence is provided with chute and pin on through hole and the pull bar, ambulatory splint is through pull bar, pin, the through hole chute can be realized opening of relative another trough rim or closure with spring, clamp is provided with earth connection jockeys such as connecting hole or bolt, large end with action bars during use is connected with connection handle, and make ambulatory splint be in open configuration, again trough rim on the clamp is hung on the electric wire that is grounded, the rotary manipulation bar makes pin enter chute then, and the ambulatory splint closure is clamped electric wire under the effect of spring, and its deficiency is to need two people to cooperate in the operating process, inconvenient operation, operating time is long, the ground connection of electric wire is of poor quality.
Summary of the invention:
The purpose of this utility model is to overcome above-mentioned the deficiencies in the prior art, and short, the measured insulated conductor earth potential of ground connection matter of a kind of easy to operate, activity duration hook of starting to exchange fire is provided.
The utility model can reach by following measure:
A kind of insulated conductor earth potential hook of starting to exchange fire, comprise coupler body, ambulatory splint, coupler body is provided with groove and earth connection jockey, the last trough rim that it is characterized in that coupler body is the semicircle hook-type, the following trough rim of coupler body is provided with the connection screw, screw rod matches with being connected screw, and an end of screw rod is connected with ambulatory splint, and the other end of screw rod is provided with connection handle.
The working face of the ambulatory splint in the utility model can semicircular in shape, and the last trough rim of ambulatory splint and coupler body can form a circle or similar circle, so that electric wire is tightly clamped, guarantees the ground connection quality.
Earth connection jockey described in the utility model generally is provided with screw on coupler body, earth connection is fixed by spring pad, bolt, also can adopt to connect the cellular type structure, earth connection is passed connecting hole fix.
The utility model can be respectively equipped with the conduction thorn on trough rim on ambulatory splint working face and the coupler body, laterally generally be provided with 3-6 row conduction thorn on the clamping cambered surface that the last trough rim of ambulatory splint and coupler body forms, vertically generally be provided with 4-5 row conduction thorn, to puncture insulating barrier, electric wire is contacted with earth connection well, guarantee the ground connection quality of electric wire.
When the utility model uses, elder generation's rotary screw make ambulatory splint relatively another trough rim be in and open shape, action bars is connected with connection handle, the last trough rim that will press from both sides the coupler body of hook again hangs on the electric wire that is grounded, the rotary manipulation bar moves along groove by the screw drive ambulatory splint then, the last trough rim of ambulatory splint and coupler body forms the circular arc working face electric wire is tightly clamped, conduction on the circular arc working face punctures insulating barrier and closely contacts with electric wire, electric wire is connected in high quality with earth connection, has easy to operate, activity duration is short, save manpower, ground connection quality height, safe in utilization, economical with materials, advantages such as long service life.
