Abstract
The utility model discloses a general anti-dropping grounding wire for a transformer substation. The general anti-dropping grounding wire comprises an upper wire-pressing plate and a lower wire-pressing plate. The opening end at the lower portion of the upper wire-pressing plate is provided with an opening spring tongue. The middle portion of the upper wire-pressing plate is provided with an upper wire-pressing groove. The other end of the upper wire-pressing plate is fixedly welded with the upper end of a threaded rod. The middle portion of the lower wire-pressing plate is provided with a lower wire-pressing groove. The lower wire-pressing plate is provided with a screw hole which runs through the lower wire-pressing plate. The end of the lower wire-pressing plate is provided with a grounding wire connection hole. The lower end of the threaded rod penetrates through the screw hole and is in screw connection with an insulation handle. The general anti-dropping grounding wire is simple in structure and convenient to produce and the requirements of hanging busbars and buses and wires are met in grounding, so that only the general anti-dropping grounding wire is needed to be installed in workplace, the variety and the number of stored grounding wires are thus reduced, resources are prevented from being left unused and wasted, and the general anti-dropping grounding wire can be widely and generally applied to power enterprises and large power consumers and has excellent market popularization prospect.
Description
Technical field:
The utility model relates to a kind of earth connection, particularly relates to the general earth connection of slip-off preventing for a kind of transformer station, belongs to power industry managing security tools and instruments technical field.
Background technology:
Earth connection is to carry out ground connection use when unexpectedly there is voltage on the equipment having had a power failure and circuit, to guarantee staff's personal safety, is widely used in power domain.In actual use, often different equipment need to configure the earth connection of different size, in maintenance and repair, need to carry different earth connections and adapt to different user demands, comparatively loaded down with trivial details.At present, the portable earth connection that China electric power system is used, has according to the classification of joint form: single tongue formula, double tongue type, the type such as spiral presses formula, holds flat, hedgehog hydnum formula.Single tongue formula wherein, double tongue type is mainly used in circuit or bus and has a power failure and use while doing safety measure; Spiral presses formula, holds flat, is mainly used in when safety measure is done in busbar power failure and uses.
Due to the difference of grounding wire connector form, in actual applications, the earth connection of hanging wire road and bus can not be applied in bus-bar earthing easily, same, and earth connection used during bus-bar earthing can not conveniently be applied to the ground connection of circuit and bus.So just cause earth connection deficiency and the remaining strange phenomenon of earth connection in actual production.As not enough in the ground wire of hanging earthing conductor bus, and the earth connection that extension busbar is used is not used, on the contrary there is same situation.If be equipped with the enough various forms of earth connections of quantity, need to increase the input of fund, cause when increasing cost and increased again maintenance, also caused the idle and waste of ample resources simultaneously.
Utility model content:
Technical problem to be solved in the utility model is: the problem there are differences in order to solve power transmission and transformation line grounding wire connector, a kind of general earth connection of slip-off preventing for transformer station that can meet distinct device grounding requirement is provided, this earth connection can meet the requirement of hanging busbar, can meet again the grounding requirement of hanging bus and wire, thereby reduced kind and the quantity of stock's earth connection, avoided the idle and waste of resource.
The utility model is that the technical scheme that technical solution problem is taked is:
With the general earth connection of slip-off preventing, comprise tension disc and lower tension disc, described upper tension disc lower open end is provided with opening bullet tongue, and upper tension disc middle part is provided with pressuring line groove, and the upper tension disc other end and screw rod upper end are fixed and welded together; Described lower tension disc middle part is provided with lower pressuring line groove, on described lower tension disc, is provided with the screw that runs through lower tension disc, in the end of lower tension disc, is provided with earth connection connecting hole; Described screw rod lower end links together through screw and insulated handle spiral.
Between described opening bullet tongue and upper tension disc, be provided with back-moving spring.
Described upper tension disc and screw rod are " L " type structure.
Good effect of the present utility model is as follows:
1, the utility model can meet the requirement of hanging busbar, can meet again the grounding requirement of hanging bus and wire, job site only need be equipped with the general earth connection of slip-off preventing for transformer station of the present utility model, thereby kind and the quantity of stock's earth connection have been reduced, avoided the idle and waste of resource, in electric power enterprise and large-scale power user, can obtain extensively generally applying, market value is considerable.
2, the utility model is simple in structure, easy to make, and upper tension disc and lower tension disc are fixed together by screw rod, by upper pressuring line groove and lower pressuring line groove, bus or busbar is compressed, and crimping is firm, has improved operating efficiency, has good marketing prospect.
3, on the utility model, tension disc lower open end is provided with opening bullet tongue, its structure is identical with key chain opening-closing structure, even if bus and wire depart from from groove, owing to playing the barrier effect of tongue, also can from grounding wire connector, not depart from, easy to use, safe and reliable.
Accompanying drawing explanation:
Fig. 1 is structural representation of the present utility model.
Embodiment:
Below in conjunction with accompanying drawing, the utility model is described further:
Referring to Fig. 1, the general earth connection of slip-off preventing for a kind of transformer station, comprise tension disc 1 and lower tension disc 8, at upper tension disc 1 lower open end, be provided with opening bullet tongue 9, between opening bullet tongue 9 and upper tension disc 1, be provided with back-moving spring 10, at upper tension disc 1 middle part, be provided with pressuring line groove 2, upper tension disc 1 other end and screw rod 3 upper ends are fixed and welded together, and upper tension disc 1 is " L " type structure with screw rod 3; At lower tension disc 8 middle parts, be provided with lower pressuring line groove 7, on lower tension disc 8, be provided with the screw 5 that runs through lower tension disc, in the end of lower tension disc 8, be provided with earth connection connecting hole 4; Described screw rod 3 lower ends link together through screw 5 and insulated handle 6 spirals.
The utility model can meet the requirement of hanging busbar, can meet again the grounding requirement of hanging bus and wire, job site only need be equipped with the general earth connection of slip-off preventing for transformer station of the present utility model, thereby kind and the quantity of stock's earth connection have been reduced, avoided the idle and waste of resource, in electric power enterprise and large-scale power user, can obtain extensively generally applying, market value is considerable.
The above; it is only preferred embodiment of the present utility model; not the utility model is done to any pro forma restriction; any simple modification, equivalent variations and modification that every foundation technical spirit of the present utility model is done above embodiment, within all still belonging to the protection range of technical solutions of the utility model.
