Abstract

The utility model relates to an all prefabricated high-voltage power cable terminal, which comprises an outgoing line hardware fitting, a semiconducting shielding cover, an insulating rain skirt, a rubber stress combining cover and a stress cone. The stress cone is pre-inbuilt in the combining cover of the stress cone, the insulating rain skirt is made by injection molding and is made of specific rubber, the insulating rain skirt is sheathed on the combining cover of the stress cone, and the insulating rain skirt is orderly sheathed with the semiconducting shielding cover and the outgoing line hardware fitting. The utility model has the advantages of simple structure, easy manufacture, convenient installation and safety, and can be effectively used for a long time. The utility model is suitable to being popularized in the installation of high-voltage power cables of power departments.

Description

A kind of full prefabricated high voltage power cable terminal

The utility model relates to field of electrical equipment, and refering in particular to is a kind of full prefabricated high voltage power cable terminal.

In the routine work of power department, usually to install cable termination in advance for setting up the high voltage power cable line.Though the cable termination of being used always on the market at present uses reliable, insulating properties is better, owing to due to the defective in its design, still exist many problems.Referring to accompanying drawing 1, high voltage power cable terminal commonly used generally is a fabricated structure, assemble in order by parts such as binding post 11, collar 12, gland 13, radome 14, silicone oil 15, insulator 16, stress cone cover 17, stress cone 18, awl holder 19, supporting insulator 110, tail pipe 111 and earth terminals 112, its part is various, structure is comparatively complicated, and its volume is bigger, and length is long, installs inconvenient; Simultaneously, the external insulation layer of this terminal is made of insulator, though this structure can play the effect of insulation preferably, it is in running, in case the phenomenon that the words of blasting because of accident will cause broken ceramics to hurt sb.'s feelings takes place, danger is bigger; In addition, the space between insulator and the inner body need be filled to reduce partial discharge with dielectric, has improved cost.Therefore, caused many inconvenience in use for power department.

The purpose of this utility model is to overcome the deficiency of above-mentioned prior art and provides a kind of simple in structure, and reasonable in design, processing and manufacturing is easy, and is easy to install, safe and reliable, and full prefabricated high voltage power cable terminal that can permanently effective use.

The purpose of this utility model is achieved like this: it comprises outlet gold utensil, semi-conductive screen cover, insulation rain skirt, rubber stress combination cover and stress cone, described stress cone is embedded in the stress cone combination cover in advance, insulation rain skirt is by specific injection molding of rubber, the rain skirt that will insulate is enclosed within the stress cone combination and puts, and socket semi-conductive screen cover and outlet gold utensil get final product successively more thereon.

The utility model is owing to adopted said structure, make it structurally be simplified, volume reduces greatly, the use of rubber-covered rain skirt more makes its fail safe be able to bigger raising, can avoid because of the hurt sb.'s feelings generation of phenomenon of accident, performances such as sealing, waterproof are all strengthened, and are suitable for power department and promote the use of when high voltage power cable is installed, and are the desirable renewal products of existing insulation terminal.

Concrete structure of the present utility model, below accompanying drawing describe in detail:

Accompanying drawing 1 is the structural representation of existing cable terminal.

Accompanying drawing 2 is a structural representation of the present utility model.

See accompanying drawing 2, the utility model comprises outlet gold utensil 21, semi-conductive screen cover 22, insulation rain skirt 23, rubber stress combination cover 24 and stress cone 25, described stress cone 25 is as required and by the moulding of semiconductive macromolecular material, stress cone 25 is embedded in stress cone combination cover 24 middle and lower parts of rubber formation, the insulation rain skirt 23 of umbrella by silicon rubber or ethylene propylene diene rubber through special mold injects moulding, it both can be overall structure, also can combine by several, the rain skirt 23 that will insulate is enclosed within on the stress cone combination cover 24, and coat extraordinary fluid sealant at each interface and make it to closely cooperate and form wholely, socket semi-conductive screen cover 22 and outlet gold utensil 21 get final product successively more thereon.

Insulation rain skirt 23 and rubber stress cone combination cover 24 is directly to be socketed on the cable in the utility model.

Below in conjunction with embodiment the utility model is described further: when using the utility model, different needs according to high voltage power cable, several insulation rain skirts 23 and stress cone combination cover 24 are nested together, it directly are socketed on the cable cable, to reduce partial discharge; Simultaneously, in case have an accident, because its external insulation made by elastomeric material, the situation that the fragment that therefore also can not occur exploding is hurted sb.'s feelings is improved fail safe.
