The conducting shoe is disposed in both ends of the shielded joint body and then is installed into the aluminum case, tightening the screws, thereby forming joint union. The shielded joint body, which is provided with a high-voltage shielding case inside, distributes the complexly distributive electrical field and is with excellent insulating property and long service life. Further, the shielded joint body is respectively provided with expanding interfaces, the conductor connecting and disjunctive jack of the cable distribution, reasonably and compactly constructing. The aluminum case is provided with flange holes on the ambilateral end faces through which the joint bodies are steadily consolidated, and is provided with screwed holes utilized in the binding connection with the metal case of the endocone push-pull terminal.
Description
Technical field:
The utility model relates to a kind of midium voltage cable and divides welding system (to be used for rated voltage 10kV (U
m=12kV) to 35kV (U
m=40.5kV) the cable branch device of a kind of novel concept of inner cone plug-in cable distribution box) body one fittings body unit (abbreviation fittings body).
Background technology:
It is to weigh the quality standard of cable distribution system that midium voltage cable divides the quality of welding system center tap body, directly influences the fail safe and the reliability of cable distribution box hanging net operation.In the midium voltage cable distribution box that existing domestic manufacturer produces, the electric cable accessories close with the fittings body effect has these three kinds at common indoor terminal, the detachable terminal of non-shield type and the detachable terminal of shield type, no matter but be on technical performance (insulation property and barrier propterty), still in installation, test, maintenance and on useful life, all can not be satisfactory.For example: adopt the cable distribution box of common indoor terminal, its high-voltage electrical apparatus connects may exist the bare metal part, and insulation property and barrier propterty are poor, and fail safe is bad, needs maintenance and useful life short; Adopt the cable distribution box of the detachable terminal of non-shield type, though insulation property and barrier propterty are quite a lot of, poor stability; Adopt the cable distribution box of the detachable terminal of shield type, fail safe is better, but connecting pattern, conductor can only be set bolt syndeton (when rated current during) greater than 400A, for the 35kV cable distribution box, its scalability is undesirable, and insulation property and barrier propterty are difficult to accomplish: 1. insulation property satisfy partial discharge quantity 45kV＜10pC, rated short duration power-frequency withstand voltage 117/5min, rated lightning impulse withstand voltage 200kV ± 10 time; 2. barrier propterty satisfies insulated outer surface has conductive shielding layer to add the sealing metal shell, really has anti-flood submergence performance.Substituted traditional common indoor terminal, the fittings body of detachable terminal of non-shield type and the detachable terminal structure of shield type, except should having excellent insulation property and barrier propterty, in configuration aspects, also should design expansion interface, keep good scalability, be convenient to the assembly unit of fittings body, the conductor that also should design cable branch connects, the disjunction socket, being convenient to inner cone plug-in terminal is inserted in the fittings body, guarantee the mechanical strength that ground connection is reliable and enough simultaneously, so the design of fittings body is the key that midium voltage cable divides welding system, but existing technology is difficult to address this problem.
Summary of the invention:
The purpose of this utility model is to overcome the deficiencies in the prior art part, a kind of fittings body is provided, the conductor that midium voltage cable divides welding system to finish cable branch by it connects and disjunction, the midium voltage cable that uses this fittings body divides welding system to have excellent insulation property, barrier propterty and good scalability, security performance is higher, move more reliably, the midium voltage cable distribution box has been improved a class.
For achieving the above object, the technical scheme that the utility model provides is: mainly constitute by shielded joint body, a conduction piece, aluminium shell, and the conduction of packing at a shielded joint body two ends piece, one is put into the aluminium shell then, uses screw-driving, just forms the fittings body unit; The shielded joint body adopts the rubber insulation material manufacturing, electric field computed in software through the advanced person is optimized, indoor design has rational high-tension shielding cover, evenly the electric field of complex distributions, excellent insulation performance, long service life, its both sides end face is connected with the conductor that the lower surface is designed expansion interface and cable branch respectively, the disjunction socket, compact conformation, reasonable; The both sides end face of aluminium shell all designs the adpting flange hole of splicing usefulness, connects fasteningly during the fittings body assembly unit by its, and the lower surface design has screwed hole, is used for fastening with being connected of the metal shell of inner cone plug-in terminal.
After the utility model adopted said structure, fittings body had extremely strong autgmentability, by link-bus tie, can carry out assembly unit to two or more fittings bodies, forms two branches or multiple-limb fittings body, and assembly unit is simple and convenient, reliable and stable.Inner cone plug-in terminal can be inserted in the fittings body, constitutes the connection of cable branch, simultaneously, and the versatility of fittings body, excellent interchangeability, (50～630mm in the suitable cross-section of cable scope of design
2) general, change cable and do not change fittings body.Because the aluminium shell is housed outward, fittings body ground connection is reliable, mechanical strength is good, the assembly unit of fittings body and the conductor of cable branch connect and disjunction all is among full-shield, all insulation, hermetically sealed, the full protection, make the cable distribution system have excellent insulation property and barrier propterty, guaranteed the stable, reliable of cable distribution system, fail safe is higher.
Description of drawings:
Accompanying drawing 1A, accompanying drawing 1B are structural representation of the present utility model (single fittings body);
Accompanying drawing 2 carries out spliced structural representation (two branch joint bodies) for the utility model;
Accompanying drawing 3 carries out spliced schematic appearance (two branch joint bodies) for the utility model;
