Along with the development of China's power construction, the continuous of electricity needs risen, and the demand of power cable increases increasingly.Cable accessory products is widely used, and has driven production domesticization, seriation that cable accessory products is produced.The extensive use of power cable with cross-linked polyethylene insulation has promoted the fast development of electric cable accessories.Crosslinked cable is widely used in the net of city, be subject to the restriction of production equipment and transportation condition due to the factory length of cable, the factory length of high-tension cable is generally between 400～800 meters, the length of cable line is generally in the 2kM left and right, therefore, the Development of Urban electrical network will need a large amount of cable intermediate joints.There is following defective in traditional cable intermediate joint: 1, the conductor coupling portion position does not have metallic shield, comes the space of filled cable conductor connection fully by wrapped band, can't accomplish that smooth surface is smooth; 2, the cable insulation end does not have special processing, and during operation, the cable insulation retraction just might make cable insulation exceed the high-tension shielding scope; 3, the main insulation body of straight coupling and insulating joint is different, has increased die cost, production cost and stock.
In order to address the aforementioned drawbacks, there is manufacturer to propose to increase in the conductor coupling portion position solution of metallic shield, make conductor connection accomplish that smooth surface is smooth, but still do not solve the problem that the cable insulation retraction brings, do not solve the different problems such as cost that increase of straight coupling and insulating joint main insulation body yet.
The utility model content
The purpose of this utility model is to provide a kind of Novel joint main body of high-pressure cross-linking cable transition joint, and this adapter body is simple in structure, and good seal performance can prevent the problem that the cable insulation retraction brings.Another purpose of the present utility model is to provide the novel transition joint that is comprised of adapter body.
For reaching above-mentioned purpose, the utility model adopts following technical scheme: a kind of adapter body of high-pressure cross-linking cable transition joint, by insulating barrier, the high-tension shielding cover that is arranged on stress cone in insulating barrier and high-tension shielding pipe, is used for being electrically connected to the cable conductor connecting fitting of two cables and is arranged on two cable junctions forms, it is characterized in that, groove is offered in end at two cable insulations, the two ends of described high-tension shielding cover respectively engaging in the groove of two cable insulation ends.
According to as above scheme, the cable insulation end fluting that is being connected, with the high-tension shielding cover, the insulation end of two cables is hooked, guarantee when operation and can not cause accident outside the high-tension shielding pipe because the cable insulation retraction cause the insulation end, guaranteed security of operation.
Further, be provided with wire netting between described high-tension shielding cover and cable conductor connecting fitting, described high-tension shielding cover makes its equipotential by wire netting and cable conductor connecting fitting electrical connection.
As preferably, described insulating barrier, stress cone and high-tension shielding pipe are one-body molded.Simple in structure, be convenient to test and install.
Novel high-pressure crosslinked cable intermediate connector by the adapter body of above-mentioned high-pressure cross-linking cable transition joint forms is characterized in that, also comprises the wrapped band, protection copper shell, fiberglass containment vessel, sealing perfusion agent and the earth cable that are wrapped in the insulating barrier outside.Existing transition joint is connected in above-mentioned wrapped band, protection copper shell, fiberglass containment vessel, sealing perfusion agent with earth cable connected mode connection gets final product.Take the processing mode of full-shield when the external shield of such transition joint, just can form the straight-through transition joint of high-pressure cross-linking cable; An end insulate, the processing mode of all the other shieldings when the external shield of such transition joint has been taked, and just can form the high-pressure cross-linking cable insulation intermediate connector.
The utility model possesses following outstanding advantages and effect with respect to prior art:
1, the high-tension shielding pipe in adapter body, stress cone and three layers of employing prefabricated of insulation, co-extrusion becomes an integral body, and is simple in structure, is convenient to test and installs.
2, the utility model can form the straight-through transition joint of the crosslinked cable that is applicable to the 110kV---220kV electric pressure or cross-linked cable insulating transition joint, highly versatile.
3, the utility model is at the insulating barrier end of two cables that are connected fluting, with the high-tension shielding cover, the insulating barrier end hooked, and prevents from occuring due to the interruption of service that the cable insulation retraction causes, and guaranteed security of operation.
