Abstract
The invention relates to an electric power cable set, aiming at the defects of complicated installation and so on of the prior insulated joint, the invention provides a full cold shrink cross-bonded cable insulated joint which is sleeved on a joint of cross-bonded cables. The insulated joint comprises a hollow joint main body and a supporting tube which his inserted into a hollow part of the joint main body and can be pulled out; two ends of the joint main body are provided with stress cones which are compounded with the joint main body into a whole. When the full cold shrink cross-bonded cable insulated joint of the invention is mounted, only the supporting tube in the insulated joint is needed to be pulled out, the whole process needs not fire and expanding operations, and are easy to realize. At the same time, because the main body adopts elastic materials, the invention can adapt to cables with different inner diameters, and generates good sealing effect.
Description
Technical field
The present invention relates to electric cable fitting, more particularly, relate to a kind of full chilling shrink crosslinked cable insulation joint.
Background technology
Current, electric energy has become energy form main among social production and the human lives.The transmission of electric energy be unable to do without power cable, simultaneously, the electric cable accessories supporting with it, its effect also can't neglect.As the insulating joint of one of annex, undertaking the vital task that connects the two ends power cable, its quality that connects effect directly influences the efficient of electric energy transmitting.
But insulating joint field fabrication; its process relates to cutting, cleaning, the crimping of core; the baking installation of heat-shrinkable T bushs such as stress control tube, inside and outside insulated tube, semiconductive pipe and the installation of copper shield net; and the winding of protective material, welding etc., complex procedures and require very high to construction level.
Except that field fabrication, current use is more also comprises a kind of prefabricated insulating joint.In installation process, mechanically the adapter body of being made by elastomeric material is carried out the scene expansion earlier, after cable core crimping place being moved to the formulation position, remove external force, utilize the radial pressure of elastomeric material that core crimping place is packed tightly.Although compare with the field fabrication mode, the prefabricated insulating joint has been simplified installation process to a certain extent, and its installation dimension need be corresponding one by one with cable dimension, so just makes its versatility relatively poor, and simultaneously, the on-the-spot process of expansion before installing is also very required great effort.
Therefore, need simple, the widely applicable insulating joint of a kind of installation process.
Summary of the invention
The technical problem to be solved in the present invention is, at existing insulating joint the defective of complexity etc. is installed, and a kind of full chilling shrink crosslinked cable insulation joint is provided.
The technical solution adopted for the present invention to solve the technical problems is: construct a kind of full chilling shrink crosslinked cable insulation joint, be socketed on the junction between the crosslinked cable, described insulating joint comprises the hollow joint main body, and inserts stay pipe described adapter body hollow space, that can extract out; Described adapter body two ends are provided with stress cone, and itself and described adapter body are combined into one.
Full chilling shrink crosslinked cable insulation joint of the present invention, the stage casing of described adapter body is provided with the shielded-plate tube around its hollow space, and itself and described adapter body are combined into one.
Full chilling shrink crosslinked cable insulation joint of the present invention, described adapter body appearance is provided with screen.
Full chilling shrink crosslinked cable insulation joint of the present invention, the core of described commissure cable insert in the described stay pipe, and after described stay pipe was extracted out, described core was packed tightly by described adapter body, and core crimping place is packed tightly by described shielded-plate tube.
Full chilling shrink crosslinked cable insulation joint of the present invention, described screen are the copper shield net.
Full chilling shrink crosslinked cable insulation joint of the present invention, described adapter body is made by the liquid silastic cooling.
Full chilling shrink crosslinked cable insulation joint of the present invention, described stress cone is made by the liquid silastic cooling.
The invention has the beneficial effects as follows that the stay pipe that full chilling shrink crosslinked cable insulation joint of the present invention only need be extracted out in the insulating joint when mounted gets final product, whole process need not to get angry and carries out dilation procedure, and is simple.Simultaneously, because main part adopts elastomeric material, therefore can adapt to the cable of different inner diameters, and can produce good sealing effectiveness.
Description of drawings
The invention will be further described below in conjunction with drawings and Examples, in the accompanying drawing:
Fig. 1 is the structural representation of full chilling shrink crosslinked cable insulation joint of the present invention.
Embodiment
The present invention has introduced a kind of full chilling shrink crosslinked cable insulation joint, and following constipation closes concrete accompanying drawing it is introduced.
Fig. 1 is the structural representation of full chilling shrink crosslinked cable insulation joint of the present invention.As shown in Figure 1, this insulating joint comprises adapter body 1, stay pipe 2, stress cone 3 and 4, shielded-plate tube 5 and screen 6.Wherein, adapter body 1 is a hollow structure, is made by the liquid silastic cooling, serves as dielectric; Therefore the internal diameter of adapter body 1 hollow space, needs in manufacture process less than the internal diameter of stay pipe 2, with the hollow space expansion of adapter body 1, so that insert stay pipe 2; Stress cone 3 and 4 lays respectively at the two ends of adapter body 1, is made by the liquid silastic cooling, and is combined into one with adapter body 1; Shielded-plate tube 5 is positioned at the stage casing of adapter body 1, is provided with in the mode of wound joint main body 1 hollow space, and is combined into one with adapter body 1; Screen 6 is overlying on the appearance of adapter body 1, is made by the copper shield net.In addition, full chilling shrink crosslinked cable insulation joint of the present invention also comprises: semi-conductive adhesive 11, fluid sealant 12, copper sheathing 13, semi-conductive tape 14, copper are pricked silk 15, are warded off lead 16, fluid sealant 17, earth connection 18 and pyrocondensation protecting pipe 19.
In installation process, at first will need the core 7 of two crosslinked cables connecting and the stay pipe 2 that 8 one of them (for example 7) penetrate full chilling shrink crosslinked cable insulation joint of the present invention; With after the core 7 and 8 crimping of two crosslinked cables and installing conductor connecting tube 9, full chilling shrink crosslinked cable insulation joint of the present invention is moved to crimping 10 places of two cores 7 and 8, and shielded-plate tube 5 is surrounded crimping place 10 fully, extract stay pipe 2 then out.After removing stay pipe 2, elastically-deformable adapter body 1 taking place when before expanding recovered, produce powerful radial pressure thus, two cores 7 and 8 are packed tightly, and packed tightly by crimping place 10 of shielded-plate tube 5 with core, produces good sealing effectiveness.
Compared with prior art, the full chilling shrink crosslinked cable insulation joint of introduction of the present invention also has more on performance Advantage is in particular in: aspect work frequency pressure, outdoor terminal of the present invention is 192kV, and prior art is 160kV; Aspect impulse withstand voltage, the present invention is 650kV, and prior art is 550kV; In shelf depreciation On, the present invention is 128kV＜1PC, prior art is 96kV＜5PC.
Full chilling shrink crosslinked cable insulation joint of the present invention only need be extracted the stay pipe in the insulating joint when mounted out Get final product, whole process need not to get angry and carries out dilation procedure, and is simple. Simultaneously, adopt owing to main part Use elastomeric material, therefore can adapt to the cable of different inner diameters, and can produce good sealing effectiveness.
