Abstract

The utility model relates to a grounding wire device of a transformer substation, in particular to a vertical grounding wire clamp which is convenient for operation and good in using effect, and comprises a clamp body and a movable clamping plate, wherein the clamp body is provided with a groove and a grounding wire connecting device. The vertical grounding wire clamp is characterized in that the lower groove side of the clamp body is provided with a screw hole; one end of a screw rod is connected with the movable clamping plate, and the other end thereof is provided with a connecting handle; when in use, the screw rod is firstly rotated to lead the movable clamping plate to be in a stretching state relative to the other groove side; an operating rod is connected with the connecting handle, and the upper groove side of the clamp body is hung on a grounded electric wire; and then, the operating rod is rotated, and the movable clamping plate is driven to move along the groove by the screw rod, so that the electric wire is firmly clamped. The vertical grounding wire clamp has the advantages of convenient operation, safe use, high ground connection quality, long service life and the like.

Description

A kind of vertical junction ground clamp
Technical field:
The utility model relates to the grounding wire device of transformer station, particularly a kind of easy to operate, vertical junction ground clamp that result of use is good.
Background technology:
As everyone knows, clearly stipulate in " electric power safety working regulation ": the technical measures of trouble free service on the electric equipment: have a power failure, electrical verification, ground connection, hang Sign Board and installing and block (fence), on the converting equipment of maintenance, install earth connection, be the basic measures that guarantee maintainer's personal safety, the operation of mounting or dismounting earth connection is dangerous bigger operation in the electric operation, in case have an accident, with regard to the entail dangers to person, equipment, the safe and stable operation of electrical network, its influence is big, consequence is serious, the charged ground connection line or belt ground wire that articulates send the accident of electricity not rarely seen in the electric power system, and be listed in one of pernicious misoperation fault, 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, the ambulatory splint closure is clamped electric wire under the effect of spring, and its deficiency is an inconvenient operation, fault rate height in the operating process, 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 a kind of easy to operate, safe in utilization, vertical junction ground clamp that ground connection is effective is provided.
The utility model can reach by following measure:
A kind of vertical junction ground clamp comprises clamp, ambulatory splint, and clamp is provided with groove and earth connection jockey, it is characterized in that the following trough rim of clamp is provided with screw, and an end of screw rod is connected with ambulatory splint, and the other end of screw rod is provided with connection handle.
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.
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, again trough rim on the clamp is hung on the electric wire that is grounded, the rotary manipulation bar moves along groove by the screw drive ambulatory splint then, electric wire is tightly clamped, had easy to operate, safe in utilization, ground connection quality advantages of higher.
Description of drawings:
Accompanying drawing is a structural representation of the present utility model.
Embodiment:
Below in conjunction with accompanying drawing the utility model is further described:
As shown in drawings, a kind of vertical junction ground clamp, comprise clamp 1, ambulatory splint 2, clamp is provided with groove and earth connection jockey 3, above-mentioned same as the prior art, this does not give unnecessary details, the following trough rim of clamp 1 that is characterised in that of the present utility model is provided with screw, one end of screw rod 4 is connected with ambulatory splint 2, and the other end of screw rod 4 is provided with connection handle, and earth connection jockey 3 described in the utility model generally is provided with screw on coupler body, earth connection is by spring pad, bolt is fixed, it belongs to those skilled in the art should know that this does not give unnecessary details, and also can adopt to connect the cellular type structure, earth connection is passed connecting hole to be fixed, when the utility model uses, first rotary screw make ambulatory splint relatively another trough rim be in and open shape, action bars is connected with connection handle, again trough rim on the clamp is hung on the electric wire that is grounded, the rotary manipulation bar moves along groove by the screw drive ambulatory splint then, and electric wire is tightly clamped, and has easy to operate, safe in utilization, ground connection quality advantages of higher.
