Abstract
A kind of cable termination ground protection pincers; comprise two clamp handles and two jaws; this two jaws opposite side is formed with arc electrical contact face; two jaw tops are bent outwardly all at a certain angle and are formed with the first binding clip and the second binding clip; two first binding clip opposite sides and the two second binding clip opposite sides of this two jaw are all formed with arc electrical contact face, and two jaws are at least connected with a wiring circle.Be applicable to 10kV and following circuit connection termination or bus-bar earthing, to the cylinder of different size and plate body wiring, ground connection can be installed; Also spring is set, makes electrical connection more reliable for supplementary pressure, improve maintainer's fail safe, reduce because of the unexpected charged casualties rate caused of cable.
Description
Technical field
The utility model relates to controller switching equipment Work tool field, particularly a kind of cable termination ground protection pincers.
Background technology
At present, during power switch cabinet maintenance, ground protection is not carried out to cable termination.In traditional maintenance process, only ground connection is carried out to isolating switch and busbar, ground connection is not carried out to the cable of turnover switch cubicle, 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 bolt connect equipment, it is less that sky reserves conducting metal contact-making surface, and cable diameter is not of uniform size, and conventional interim three-phase shortcircuit earth connection is difficult to installing, easily comes off.When after dismounting cable joint bolt, now depart from grounding switch or earth connection protection, there is induced electricity or fall the danger of power transmission.At present, a kind of ground protection pincers making cable termination earthy when being specifically designed to maintenance are not had.Given this plant situation, design a ground protection pincers had for ground connection first during cable termination dismounting, just necessary for electric power system maintenance.
Utility model content
Main purpose of the present utility model is to overcome in prior art, proposes a kind of safe and reliable, easy to operate cable termination ground protection pincers.
The utility model adopts following technical scheme:
A kind of cable termination ground protection pincers; comprise two clamp handles and two jaws; this two jaws opposite side is formed with arc electrical contact face; two jaw tops are bent outwardly all at a certain angle and are formed with the first binding clip and the second binding clip; two first binding clip opposite sides of this two jaw are provided with serrated contact face; two second binding clip opposite sides are formed with arc electrical contact face, and two jaws are at least connected with a wiring circle.
Preferably, described two clamp handle tops are formed with the cavity holding described two jaws respectively, this jaw and respective chamber side walls hinged, also opening top between this cavity inner wall and described jaw sidewall has spring with supplementary pressure.
Preferably, described wiring circle is through described clamp handle and one-body molded with jaw.
Preferably, described arc electrical contact face is zigzag arc electrical contact face.
From above-mentioned to description of the present utility model, compared with prior art, the utility model has following beneficial effect:
1, ground connection of the present utility model pincers are provided with jagged arc electrical contact face, are applicable to 10KV and following circuit connection termination or bus-bar earthing, can install ground connection to the cylinder of different size and plate body wiring;
2, the utility model also arranges spring at jaw sidewall, makes electrical connection more reliable, improve maintainer's fail safe for supplementary pressure, reduces because of the unexpected charged casualties rate caused of cable;
3, the three-phase fitting operation time of the utility model ground connection pincers is less than 1 minute, easy construction, improves overhaul efficiency;
4, be zero on the dismounting of the terminal such as cable and the impact of installing.
Accompanying drawing explanation
Fig. 1 is front view of the present utility model;
Fig. 2 is end view of the present utility model;
Fig. 3 is stereogram of the present utility model;
Fig. 4 is stereogram of the present utility model (part section);
Wherein: 1, clamp handle; 2, jaw; 3a, the first binding clip; 3b, the second binding clip; 4, wiring circle; 5, spring; A is the first arc electrical contact face; B is zigzag electrical contact face; C is the second arc electrical contact face.
Embodiment
Below by way of embodiment, the utility model will be further described.
Referring to figs. 1 through Fig. 4, a kind of cable termination ground protection pincers, comprise two clamp handles 1 and two jaw 2, two clamp handle 1 tops are formed with the cavity holding described two jaws 2 respectively, and the cavity wall of this two jaw 2 respectively with corresponding is hinged.Two jaw 2 opposite side indents are formed with jagged first arc electrical contact face A.Two jaw 2 tops are bent outwardly all at a certain angle and are formed with the first binding clip 3a and the second binding clip 3b.Be provided with jagged electrical contact face B in two first binding clip 3a opposite sides of this two jaw 2, two second binding clip 3b opposite side indents form the second arc electrical contact face C.Arc electrical contact face is zigzag arc electrical contact face.
Also include at least one wiring circle 4, this wiring circle 4 is one-body molded with jaw 2 through clamp handle 1.
Further, also opening top between cavity inner wall and jaw 2 sidewall has spring 5 or jump ring with supplementary pressure, makes electrical contact more reliable.
The utility model is applicable to 10kV and following circuit connection termination or bus-bar earthing, first arc electrical contact face A, the second arc electrical contact face C are used for carrying out electrical contact with the pipe portion of binding post, and the plate portion of zigzag electrical contact face B and binding post carries out electrical contact.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 thereto, all changes utilizing this design the utility model to be carried out to unsubstantiality, all should belong to the behavior of invading the utility model protection range.
