Abstract
A cable terminal grounding clamp for safety maintenance of a switch cabinet comprises two clamp handles and two clamp mouths. A jointing clamp is arranged on the top of each clamp mouth and is arranged with a certain angle relative to a side surface of each clamp mouth. Arc electrical contact surfaces are formed at opposite sides of two jointing clamps. At least one wiring loop is arranged on each clamp mouth. The grounding clamp is provided with zigzag electrical contact surfaces and arc electrical contact surfaces, is suitable for 10 kV and below 10 kV circuit terminal studs or busbars, and can connect, mount and ground cylinders and plate-shaped bodies in different sizes. The grounding clamp is simple in operation, reliable in grounding and small in occupation space, has no influence on disassembly and installation of cable terminals, improves work efficiency for maintainers, and provides protection for safety construction.
Description
Technical field
The utility model relates to controller switching equipment Work tool field, particularly a kind of switch cubicle cable termination safety inspection ground connection pincers.
Background technology
At present, during power switch cabinet maintenance, cable termination is not carried out to ground protection.In traditional maintenance process, only isolating switch and busbar are carried out to ground connection, the cable of turnover switch cubicle is not carried out to ground connection, just in case cable is charged, personal safety accident may occur.
Hv cable termination head adopts pyrocondensation or shrinkage mode insulating material, and when copper or aluminium nose connect equipment with bolt, it is less that sky reserves conducting metal contact-making surface, and cable wire diameter is not of uniform size, and conventional interim three-phase shortcircuit earth connection is difficult to installing, easily comes off.After removing cable joint bolt, now depart from grounding switch or earth connection protection, there is induced electricity or the danger of power transmission.At present, do not have a kind of being specifically designed to while overhauling to allow the earthy ground protection of cable termination clamp.Given this plant situation, design a ground protection pincers of first ground connection while having for cable termination dismounting, just necessary for electric power system maintenance.
Utility model content
Main purpose of the present utility model is to overcome above-mentioned defect of the prior art, proposes a kind of switch cubicle cable termination safety inspection ground connection simple in structure, easy accessibility and clamps.
The utility model adopts following technical scheme:
A kind of switch cubicle cable termination safety inspection ground connection pincers, comprise two clamp handles and two jaws, it is characterized in that: this two jaws top is respectively equipped with the binding clip arranging at an angle with jaw side, this two binding clips opposite side is formed with the electrical contact face of arc, is also provided with at least one wiring circle on this jaw.
Preferably, described two binding clip ends curve inwardly and form described arc electrical contact face.
Preferably, described wiring circle is positioned at described clamp handle and position, described jaw boundary.
Preferably, described two jaw opposite sides are respectively equipped with jagged electrical contact face.
Preferably, described binding clip is metal connection folder.
From above-mentioned, to description of the present utility model, compared with prior art, the utlity model has following beneficial effect:
1, ground connection pincers of the present utility model are provided with jagged electrical contact face and arc electrical contact face, are applicable to 10KV and following circuit connection termination or bus-bar earthing, can ground connection be installed to the cylinder of different sizes and plate body wiring;
2, improve maintainer's fail safe, because the unexpected charged casualties rate causing of cable is reduced to zero;
3, the three-phase fitting operation time of the utility model ground connection pincers is less than 1 minute, and easy construction, improves overhaul efficiency;
4, on the impact of the terminal dismountings such as cable and installation, be zero.
Accompanying drawing explanation
Fig. 1 is front view of the present utility model;
Fig. 2 is vertical view of the present utility model;
Fig. 3 is perspective view of the present utility model;
Wherein: 1, clamp handle; 2, jaw; 3, binding clip; 4, wiring circle; A is jagged electrical contact face; B is arc electrical contact face.
Embodiment
Below by embodiment, the utility model will be further described.
Referring to figs. 1 through Fig. 3, a kind of switch cubicle cable termination safety inspection ground connection pincers, comprise two clamp handles 1 and two jaws 2.These two jaws, 2 opposite sides are respectively equipped with jagged electrical contact face A.These two jaws, 2 tops (for example: vertical setting), two binding clip 3 ends curve inwardly and form arc electrical contact face B, and this binding clip 3 adopts copper materials to make are respectively equipped with the binding clip 3 that arranges at an angle with jaw 2 sides.On this jaw 2, be also provided with a wiring circle 4, this wiring circle 4 is positioned at clamp handle 1 with jaw 2 positions, boundary and can conducts electricity.The quantity of wiring circle 4 is not unique, can be two yet, is arranged on two jaws 2, is positioned at the intersection of jaw 2 and clamp handle 1.
The utility model is applicable to 10KV and following circuit connection termination or bus-bar earthing, can ground connection be installed to the cylinder of different sizes and plate body wiring.Ground connection pincers of the present utility model are easy and simple to handle, and ground connection is reliable, takes up room little, do not affect cable termination dismounting and install, and for maintainer increases work efficiency, ensure that construction safety provides protection.
Above are only embodiment of the present utility model, but design concept of the present utility model is not limited to this, allly utilizes this design to carry out the change of unsubstantiality to the utility model, all should belong to the behavior of invading the utility model protection range.
