Description
Technical field
The utility model relates to a kind of high-voltage cable dry-type tapping device.
Background technology
In the practical engineering application of cable electric line, the demand of cable branch is arranged, the branch of cable is about to a cable line and branches into several cable branch circuits, can realize at interval by increasing GIS, also can realize by the cable distribution device.The prior cable tapping device only is used for the mesolow cable system, and along with the continuous development of power construction, electric network composition becomes increasingly complex, and this demand therefrom low-voltage cable system development arrives HV CABLE SYSTEM.
High-tension cable tapping device in the market mainly is two kinds of structures, a kind of is inflatable structure, this structure is inserted inlet wire cable, outlet cable in the metal box of sealing, be full of the SF6 gas of certain pressure in the metal box,, explosion-protection equipment arranged on the metal box for preventing gas burst, the tapping device of inflatable structure is bulky, the potential safety hazard that has gas leakage needs the regular detected gas pressure of operation department, brings inconvenience for operation department.Another kind of structure is the insulation shell of thermosetting solid insulating material casting, inlet wire cable, outlet cable are inserted, little, the no gas leakage danger of this kind structural volume, operation is convenient, but because solid insulating material is embedded with the different conductor material of the coefficient of expansion, in use when variations in temperature, occur the solid insulating material cracking that the stress problem causes easily, cause tapping device blast when operation.
The utility model content
The technical problems to be solved in the utility model is, a kind of high-voltage cable dry-type tapping device of simple in structure, safe in utilization, no hidden danger is provided.
For addressing the above problem, a kind of high-voltage cable dry-type tapping device of the present utility model comprises insulator, screen, electric conductor, stress-buffer layer, stress cone, contact, it is characterized in that: be provided with electric conductor in the described insulator, between insulator and electric conductor, be provided with stress-buffer layer, on the outer peripheral face of insulator, be coated with screen and place in the containment vessel, between containment vessel and screen, be provided with marine glue; The front/rear end of described electric conductor is curve form, is respectively equipped with entrance hole and wire hole on the left and right side of electric conductor, and described wire hole is more than two or two; On the position of insulator, be respectively equipped with inlet wire taper hole and outlet taper hole corresponding to the entrance hole of electric conductor and wire hole, in inlet wire taper hole and outlet taper hole, be provided with stress cone, on the outer face of stress cone, be provided with the tail pipe structure that is fixed on the insulator, and provide compression stress to stress cone by the tail pipe structure.Described tail pipe structure includes tail pipe, spring and sleeve pipe, and sleeve pipe places the front end of tail pipe, is provided with spring between sleeve pipe and tail, and spring after compression and part sleeve pipe place the inner chamber of tail pipe.During use, inlet wire cable and outlet cable pass tail pipe structure, stress cone successively and are plugged on respectively on the entrance hole and wire hole of electric conductor by fixing contact.
Adopt a kind of high-voltage cable dry-type tapping device of the present utility model, the left and right side of electric conductor is curve form, has replaced traditional planar design, has reduced the surperficial equivalent length of electric conductor, has reduced the thermal deformation size of electric conductor, can significantly reduce internal stress; Increase the semiconductive stress-buffer layer of one deck high resiliency between insulator and the electric conductor, can sponge the deformation that the electric conductor variations in temperature produces, greatly reduced internal stress, stopped thermosets stress cracking problem; Solved electric conductor and insulator and produced the gap, partial discharge occurred, caused the solid insulation problem of aging because of thermal deformation.Has advantage simple in structure, safe in utilization, no hidden danger.
