Abstract
The utility model relates to a high voltage and over high voltage cable terminal accessory, in particular to a middle connecting joint of cables, which comprising a cable(1), a tie-in main part prefabticated member(2), a grading shield(3) and a metal taking tube(4); and the cable(1) consists of a conductor(5) and a cable insulator(6); and the tie-in main part prefabticated member(2) includes a tie-in insulator(7) and a tie-in electrode(8); and the outer of the grading shield(3) is provided with the main part prefabticated member(2) and has an entirety type conductive elastomer(9) with a round shape. The utility model has the advantages of(1) simple structure and high stability. The grading shield is an integrated structure which has lower failure rate and good stability; and(2) convenient installation which improves the installation efficiency and saves the installation cost; and artful structure design. The grading shield adopts the entire structure and round shape electric conduction elastomer which not only has conductive function as metal but also has rich elasticity.
Description
Technical field
The utility model relates to a kind of high pressure, extra-high-tension cable terminal attachment, jointing in the middle of particularly a kind of cable.
Background technology
At present, in the high pressure of 66kV and the above electric pressure of 66kV, the ultrahigh voltage power cable connected system, as jointing in the middle of the cable of cable termination annex is the link of comparison weakness, break down easily, its failure rate accounts for more than 70% of whole cable connected system, and jointing directly has influence on the stability of whole system in the middle of the cable.The structure (as shown in Figure 2) of the middle jointing employing of cable at present, cable 1 comprises cable conductor 5 and cable insulation 6, adapter body prefabricated component 2 comprises splice insulation body 7, terminal electrodes 8, two cable conductor 5 front portions of removing cable insulation, the outside puts metal adapter 4 and carries out crimping, take over the grading shield 3 that wild card has had shielding action at metal, grading shield 3 is outside equipped with adapter body prefabricated component 2, grading shield is generally the semicircle becket, what adopt is two semicircular alumiaum article structures, two semicircular alumiaum articles are stuck in outside metal takes over relatively, and two alumiaum articles fix up by bolt etc. again.The grading shield structure of this minute body structure makes the middle head that connects of whole cable exist following defective: (1) grading shield is the branch body structure, therefore two semicircle alumiaum articles exist the slit, when using, operation changes owing to loading, when strengthening, duty cycle can cause the slit of grading shield to be strengthened, grading shield is the key components and parts in the jointing in the middle of the cable, jointing just breaks down easily in the middle of the whole cable, causes whole power cable connected system stability decreases; (2) grading shield is for dividing a body structure, and it is affixed to need two alumiaum articles with split carry out during installation, and this has brought inconvenience to installation.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, jointing in the middle of the cable of provide a kind of simple in structure, good stability, being convenient to install.
Realize that the above-mentioned purpose technical scheme is: jointing in the middle of a kind of cable, comprise cable, adapter body prefabricated component, grading shield, metal adapter, cable includes cable conductor, cable insulation, the adapter body prefabricated component includes splice insulation body, terminal electrodes, grading shield is outside equipped with the adapter body prefabricated component, grading shield is the integral type conductive elastomer, conductive elastomer be shaped as the pipe shape.
Further, described conductive elastomer is a conductive rubber.
After adopting technique scheme, have a lot of benefits: the utility model is to improve innovation on the basis of existing technology, improving the innovation part is to change the key components and parts grading shield into integral type pipe shape conductive elastomer by split type semicircle becket, this makes the utility model: (1) is simple in structure, good stability.Grading shield is an overall structure form, and is middle seamless, makes to have overcome that grading shield reduces failure rate of the present utility model, good stability for dividing body structure an existing defective greatly in the prior art; (2) easy for installation.During installation, it is outer just passable only to need that grading shield directly is socketed in metal tube, installs very convenient, fastly, greatly reduces working strength of workers, has improved installation effectiveness, has saved installation cost; (3) structural design is ingenious.Grading shield adopts integral type pipe shape conductive elastomer, has both had the conducting function of metal, and high resilience again makes grading shield both easy suit when metal is taken over outer suit, and suit gets closely again.
Description of drawings
Fig. 1 looks the sectional structure schematic diagram for master of the present utility model;
Fig. 2 is the structural representation of the middle jointing of cable of prior art.
Embodiment
Below in conjunction with drawings and Examples the utility model is described in further detail.
Embodiment one
As shown in Figure 1, jointing in the middle of a kind of cable, comprise cable 1, adapter body prefabricated component 2, grading shield 3, metal adapter 4, cable 1 includes cable conductor 5, cable insulation 6, adapter body prefabricated component 2 includes splice insulation body 7, terminal electrodes 8, and splice insulation body 7 and terminal electrodes 8 are made an integral body, and grading shield 3 is an integral type conductive elastomer 9, conductive elastomer 9 be shaped as the pipe shape, conductive elastomer 9 is a conductive rubber.Two cable conductor 5 front portions of removing cable insulation, the outside puts metal adapter 4 and connects, and takes over outside 4 at metal and is with grading shield 3, and grading shield 3 is outside equipped with adapter body prefabricated component 2.
The utility model is not limited to the foregoing description, and the technical scheme that all employings are equal to replacement or equivalence replacement formation all belongs to the claimed scope of the utility model.
Claims (2)
