Description
Technical field
The utility model relates to controller switching equipment Work tool field, and particularly a kind of ground protection for cable termination clamps.
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 propose a kind of safe and reliable, easy to operate ground protection pincers.
The utility model adopts following technical scheme:
A kind of ground protection pincers; comprise two hinged clamp handles; it is characterized in that: also comprise two binding clips; this two clamp handles opposite side is provided with the groove extended along its length; this two binding clip is embedded in the groove of this two clamp handle respectively; all hinged with corresponding clamp handle by pin in the middle part of this two binding clip, these upper and lower two ends of two binding clips are equipped with along bandy first binding clip in vertical clamp handle direction and the second binding clip, and two second binding clip opposite sides are provided with jagged arc electrical contact face.
Preferably, also include torsion spring, this torsion spring is arranged at the hinged place of two clamp handles.
Preferably, wiring is connected to bottom described two clamp handles.
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, binding clip of the present utility model and clamp handle pass through pin-hinges, when two first wiring clamping connections clamp terminal pipe portion, due to binding clip and clamp handle hinged, two binding clip side wall lower ends close contacts, react on two first binding clips make two first binding clips and terminal plate contact more tight; When two second wiring clamping connections clamp terminal panel, due to binding clip and clamp handle hinged, two binding clip sidewall upper close contacts, react on two second binding clips make two second binding clips and terminal plate contact more tight;
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 three-dimensional structure diagram of the present utility model;
Fig. 2 is the utility model front view;
Fig. 3 is end view of the present utility model;
Fig. 4 is the utility model schematic diagram;
Wherein: 1, clamp handle; 11, groove; 2, binding clip; 2a, the first binding clip; 2b, the second binding clip; 3, pin; 4, wiring; 5, torsion spring; A is level and smooth arc electrical contact face; B is zigzag 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 ground protection pincers, the hinged place comprising two hinged clamp handle 1, two clamp handles 1 is provided with powerful torsion spring 5.Also comprise two binding clips 2, this two clamp handle 1 opposite side is provided with the groove 11 extended along its length, and this two binding clip 2 is embedded in the groove 11 of this two clamp handle 1 respectively, and the two-arm of this torsion spring 5 is resisted against two groove 11 inwalls respectively.All hinged with corresponding clamp handle 1 by pin 3 in the middle part of this two binding clip 2, these two binding clip about 2 two ends are equipped with along vertical clamp handle 1 direction bandy first binding clip 2a and the second binding clip 2b, two second binding clip 2b opposite sides are provided with jagged arc electrical contact face B, and two first binding clip 2a are provided with level and smooth arc electrical contact face A.Wiring 4 is connected to, for the connecting line between ground connection pincers and ground network bottom two clamp handles 1.
The utility model is applicable to 10kV and following circuit connection termination or bus-bar earthing, the level and smooth arc electrical contact face A of the first binding clip 2a is used for carrying out electrical contact with binding post pipe, and the jagged arc electrical contact face B of the second binding clip 2b is used for carrying out electrical contact with the panel of binding post.When two first binding clip 2a connect clamp terminal pipe portion time, because binding clip 2 and clamp handle 1 are hinged, two binding clip 2 side wall lower ends close contacts, react on two first binding clip 2a make two first binding clip 2a and terminal plate contact more tight; When two second binding clip 2b connect clamp terminal panel time, because binding clip 2 and clamp handle 1 are hinged, two binding clip 2 sidewall upper close contacts, react on two second binding clip 2b make two second binding clip 2b and terminal plate contact more tight.
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.
