Abstract
The utility model discloses a portable maintenance grounding wire device, relating to an improvement of the grounding wire device. The portable maintenance grounding wire device has the characteristics of being small in volume, convenient to install and reliable in connection with a busbar, and comprises an insulating rod and a bus connecting head, wherein the bus connecting head comprises a rotary rod and a wire clamp; the rotary rod is provided with a rod body, a clamping pin and a thread rod; the clamping pin protrudes from the surface of the rod body; the thread rod is the same as the rod body in axis center and is fixedly arranged at the far end of the rod body; the end surface of the insulating rod is provided with a hole capable of containing the near end of the rod body, and the wall of the hole is provided with a groove matched with the clamping pin so as to lead the insulating rod to be capable of passing through the groove and the clamping pin to drive the rod body so as to further drive the rotary rod to rotate; the wire clamp forms a concave shape by a bearing piece, a connecting piece and a working piece; and a thread hole adaptive to the thread rod is arranged at the central part of the working piece, and a connecting hole for connecting a ground wire is arranged at the edge part of the working piece. The portable maintenance grounding wire device has a split type structure, and the insulating rod is multifunctional, so that not only the whole volume of the grounding wire is greatly reduced, but also the device is convenient to carry.
Description
Technical field
Grounding wire device when the utility model relates to electric power apparatus examination relates in particular to the improvement to grounding wire device.
Background technology
The fixture of tradition earth connection, its thickness has 30mm, and width is minimum to be 60mm, and length is minimum to be 100mm.And the distance between the busbar is generally about 30mm～50mm, and in so little gap, traditional earth connection is because the box house that is limited in case change, cable branch box of its size and structure just is difficult to installing.When carrying out the maintenance of cable line, usually because case becomes, the box house busbar spacing of cable branch box is less, earth connection wire clamp structure and the box inner structure be furnished with do not match, safety measure is difficult to carry out, in order to guarantee safety, the staff moves heaven and earth and finishes the installation of earth connection, and the time-consuming effort again of the process of mounting or dismounting earth connection has a strong impact on operating efficiency.In addition, existing earth connection is after maintenance is installed and carried out, the cable branch box chamber door just can't be closed, if the maintenance job site is not awkward very just near feeder pillar, will arrange the on-the-spot guard of personnel usually, the increase that this just causes the cost of overhaul is easy to generate hidden danger.
The utility model content
The utility model provides a kind of volume little, easy for installation at above problem, and is connected reliably with busbar, guarantees the portable inspection earthing line apparatus of safety.
The technical solution of the utility model is: comprise insulating bar and bus connector, described bus connector comprises swing arm and wire clamp;
Described swing arm has shaft, bayonet lock and threaded rod, and described bayonet lock protrudes in the shaft surface and is provided with; Described threaded rod and shaft concentric fixedly are located at the far-end of shaft;
The end face of described insulating bar is provided with the hole that can hold described shaft near-end, and described hole wall is provided with the groove that is complementary with described bayonet lock, makes insulating bar drive described shaft by groove, bayonet lock, and then drives described swing arm rotation;
Described wire clamp constitutes concave shape by accepting sheet, brace and active gage, and the centre of described active gage offers the screwed hole adaptive with described threaded rod, is provided with the connecting hole that is used to connect ground wire in the edge of described active gage.
Described bayonet lock is provided with a pair of, is distributed on the same circumference on shaft surface; Described groove is provided with a pair of, is distributed on the described hole wall.
The utility model according to all kinds of casees become, the wiring situation of cable branch box internal unit, set about from several aspects such as convenience, reliability, fail safes, provide a kind of highly versatile, wiring reliable technique scheme.Wherein one is earth connection fixture (wire clamp); The 2nd, the connected mode of fixture and insulating bar sets about improving.On the connected mode of fixture and insulating bar, increased by one and can realize connecting, can realize again the tight intermediate member of bus-bar (swing arm).For fixture, adopted compact conformation, taken up room for a short time, and can snap in bus row's concave shape structure from the side.It cooperates with swing arm, can bus-bar is tight.And device of the present utility model can separate insulating bar behind clamp, therefore can close the chamber door of electric box, the fail safe when having improved operation greatly, and save manpower.The utility model belongs to split-type structural, and insulating bar can multi-use, and the overall volume of earth connection is dwindled greatly, and easy to carry.
