Abstract
The utility model discloses a grounding hook, and relates to the technical field of an isolating switch or falling insurance. The device comprises an L-shaped hook and a connecting plate. The grounding hook is characterized in that more than one fixing hole is formed in the connecting plate; a vertical rod of the hook is parallel to a plane of the connecting plate and connected with the plane of the connecting plate in a welding manner; the hook is welded on the side or the surface of the connecting plate; and the hook and the connecting plate are made of copper. The grounding hook can be utilized to work just by transacting a local working ticket when a high-voltage cable has a fault and needs to be maintained; power failure of the overall circuit can be avoided; the power-cut range is reduced; the power supply reliability is improved; and meanwhile, the grounding hook is simple in structure, low in manufacturing cost, and convenient to install and use, and does not destroy the original functions of the isolating switch and the failing insurance.
Description
Technical field
The utility model relates to isolation switch or falling fuses technical field.
Background technology
It is normal important safety technical measures of using in electrical installation that ground wire articulates (referring to temporary ground wire), when particularly preparing to overhaul on electric equipment under arms, after only finishing the safety measure of hanging earthing conductor, just can be allowed to start working.Earth connection is the indispensable safety curtain of protection maintainer; the regulation of necessary hanging earthing conductor when although electrical safe working order has distribution transformer platform (frame, chamber) interruption maintenance; but be difficult to implement in practical operation, cause habitual violating the regulations, so ground wire to articulate be stubborn problem.
And along with the quickening of Process of Urbanization Construction, in the county town, 10KV and 35KV circuit adopt the steel pole design more, with high-tension cable as outlet and downlead, this just a problem occurred: when high-tension cable breaks down and needs repairing, had obvious cut-off point although pull open isolation switch, but because the isolation switch long-time running also can produce leakage current, must install the earth connection protection by both sides, rules job site, but earth connection articulates nowhere; When keeping in repair simultaneously the power distribution station of not standardized transformation, the falling fuses earth connection that just pulls open the transformer upper end still articulates nowhere.If just handle the line work ticket in order to keep in repair a branch cable, the road has a power failure so completely, and not only electric reliability can not get ensureing has also affected economic benefit.
Easy and convenient for hanging earthing conductor, not affecting under isolation switch and falling fuses original function and the normal prerequisite of using, need research to make isolation switch or falling fuses grounding hook.
The utility model content
Technical problem to be solved in the utility model is to provide a kind of grounding hook, break down when needing repairing at high-tension cable, use the utility model can avoid whole piece line outage and reduce power failure range, improved power supply reliability, simultaneously simple in structure, cheap, easy to install, and do not destroy isolation switch and falling fuses original function.
For solving the problems of the technologies described above, technical solution adopted in the utility model is:
A kind of grounding hook comprises hook, connecting plate, it is characterized in that, connecting plate is provided with more than one fixing hole, is convenient to this hook is fixed under isolation switch moving contact or falling fuses the lead-in wire place by fixing hole by holding screw; The montant of hook and connecting plate plane parallel and welding, fixing more convenient.
Welding hook the side of connecting plate or above, manufacture craft is simple.
Hook conveniently articulates earth connection for L-type.
Hook, connecting plate adopt copper material, and cheap, electric conductivity is good.
Adopt the beneficial effect that technique scheme produces to be: to break down when needing repairing at high-tension cable, use the utility model, only need handle local work ticket gets final product work, can avoid whole piece line outage and reduce power failure range, having improved power supply reliability, simultaneously simple in structure, cheap, have good electric conductivity, easy to install, and do not destroy isolation switch and falling fuses original function.

Embodiment
Embodiment 1(sees Fig. 1), hook 1 is welded on the side of connecting plate 2.Do not affecting under equipment original function and the normal prerequisite of using, hook 1 is fixed under isolation switch moving contact or falling fuses the lead-in wire place by the fixing hole 3 on connecting plate 2 by holding screw, as long as pull open isolation switch or falling fuses during use, after identifying moving contact or the lower true no-voltage of lead end, earth connection is hung in grounding hook get final product.There has been this grounding hook only need handle local work ticket and got final product work, avoided whole piece line outage, reduced power failure range, improve power supply reliability, manufacture craft is simple simultaneously, installs and uses easy and convenient, cheap, and do not destroy isolation switch and falling fuses original function.
Embodiment 2(sees Fig. 3), the main distinction of the present embodiment and embodiment 1 is as follows: the hook 1 be welded on connecting plate 2 above.Occupation mode is identical with embodiment 1.
Claims (4)
1. a grounding hook, comprise hook, connecting plate, it is characterized in that, connecting plate is provided with more than one fixing hole, the montant of hook and connecting plate plane parallel and welding.
2. grounding hook according to claim 1, is characterized in that, welding hook the side of connecting plate or above.
3. grounding hook according to claim 1 and 2, is characterized in that, links up with to be L-type.
