Description
Technical field
The utility model relates to a kind of cable system test and uses conduction connecting structure, and conduction connecting structure is used in particularly a kind of 500kV and the test of following electric pressure cable system.
Background technology
According to the requirement of standards such as IEC62067, GB/18890.1 and GB/T 22078.1, the crosslinked cable that surpasses 150kV for electric pressure need carry out the cable system test.Wherein,, should play alive effect, require it can not become point of discharge again simultaneously as the conduction connecting structure of ancillary test device.In existing means, conduction connecting structure normally adopts naked copper cash or copper bar to serve as, and covers some metallic shields again at its surface cover layer of metal paper tinsel and at the position that is connected with cable termination, is used for preventing its discharge.This method shortcoming has two: the one, and metal forming is damaged easily, and radome is very difficult fixing, has caused electric discharge phenomena; The 2nd, for the cable system of different cross section, consider the problem of heating and cable loop load-bearing, often change naked copper cash of different size or copper bar.
The utility model content
The utility model technical problem to be solved provide a kind of do not need conversion, to be common to experiment condition be 500KV and following electric pressure, cable conductor cross section 2500mm
2And conduction connecting structure is used in all following cable systems tests.
For addressing the above problem; The technical scheme that the utility model adopted is following: conduction connecting structure is used in a kind of 500kV and the test of following electric pressure cable system; Comprise two root termination outlet bars and a connecting rod, said two root termination outlet bars connect through said connecting rod; Said connecting rod comprises four parallel pipes, two fixed discs and two splicing ears, and said fixed disc is fixed on the two ends of said four pipes, and said splicing ear is fixed on the said fixed disc, and is protruding along said connecting rod axial direction; Said splicing ear is connected with said terminal outlet bar through leading-out terminal, is welded with shading ring on the said fixed disc, is covered with radome on the said leading-out terminal.
Preferably, said leading-out terminal all is connected with screw with the outlet bar at terminal with said splicing ear, said leading-out terminal.
Preferably, the material of said leading-out terminal is a copper, and the material of said radome, said shading ring and said connecting rod is an aluminium.
The utility model because the connecting rod main body adopted four pipes that parallel diameter is identical, has increased equivalent external diameter, and need not carrying out conversion, just can be common to experiment condition be 500KV and following electric pressure, cable conductor cross section 2500mm
2And all following cable systems tests; Leading-out terminal is in radome inside; The connecting rod main body is four pipes that parallel diameter is identical; The connecting rod end is welded with shading ring, and leading-out terminal is screw with splicing ear, leading-out terminal with the outlet bar at terminal and is connected, and above structure has all prevented discharge generation effectively; The material of radome, shading ring and connecting rod is an aluminium, and weight is compared gently with copper, is easy to during installation sling with driving; The outlet bar at leading-out terminal and splicing ear, leading-out terminal and terminal is screw and is rigidly connected, and between two outdoor terminals, plays mutual supporting role, makes terminal support more stable with respect to ground.
Description of drawings
Below in conjunction with accompanying drawing the utility model is done further to specify.
Fig. 1 is that the utility model 500kV and following electric pressure cable system are tested the schematic perspective view with the embodiment of conduction connecting structure.
Fig. 2 is that the utility model 500kV and following electric pressure cable system are tested the generalized section with the embodiment of conduction connecting structure.
Embodiment
Conduction connecting structure is used in the utility model 500kV and the test of following electric pressure cable system, comprises two root termination outlet bars and a connecting rod 3, and said two root termination outlet bars connect through said connecting rod 3; Said connecting rod 3 comprises four parallel pipes, two fixed discs 5 and two splicing ears 6; Said fixed disc 5 is fixed on the two ends of said four pipes; Said splicing ear 6 is fixed on the said fixed disc 5, and is protruding along said connecting rod 3 axial directions; Said splicing ear 6 is connected with said terminal outlet bar through leading-out terminal 4, is welded with shading ring 2 on the said fixed disc 5, is covered with radome 1 on the said leading-out terminal 4; Said leading-out terminal 4 all is connected with screw with the outlet bar at terminal with said splicing ear 6, said leading-out terminal 4; The material of said leading-out terminal 4 is a copper, and the material of said radome 1, said shading ring 2 and said connecting rod 3 is an aluminium.
A kind of embodiment of the utility model is following: at first radome 1 is enclosed within on the outlet bar at terminal; Connecting rod 3 is welded with shading ring 2; Then leading-out terminal 4 is enclosed within on the outlet bar at terminal; And fix with screw with it, at last the splicing ear 6 of connecting rod 3 is fixed with leading-out terminal 4 usefulness screws.Wherein the material of leading-out terminal 4 is a copper, and the material of radome 1, shading ring 2 and connecting rod 3 is an aluminium.Radome 1 plays shielding action with shading ring 2, promptly prevents discharge; Connecting rod 3 plays the effect that electric current passes through with leading-out terminal 4; The main body of connecting rod 3 is four pipes that parallel diameter is identical, and it is overheated both to have prevented, has increased equivalent external diameter again, has prevented discharge generation effectively; Leading-out terminal 4 is in radome 1 inside, has also prevented the generation of discharge.
More than a kind of 500kV and the test of following electric pressure cable system that the utility model embodiment is provided carried out detailed introduction with conduction connecting structure; For one of ordinary skill in the art; Thought according to the utility model embodiment; Part all can change on embodiment and range of application; In sum, this description should not be construed as the restriction to the utility model, and all any changes of being made according to the utility model design philosophy are all within the protection range of the utility model.
