Using the structure, the utility model has the advantages of lightness, no leakage, no maintenance, convenient dismounting, good explosion protection property and simple structure.
Description
Technical field
The utility model belongs to the High-Voltage Electrical Appliances field, is specifically related to a kind of rigid dry high-voltage cable terminal end.
Background technology
Along with the development of China's power construction, the continuous of electricity needs risen, and the demand of high voltage power cable increases day by day, and the HV cable accessories product is being extensive use of, and the HV cable accessories product domesticizes, seriation.At present, the crosslinked polyethylene hv cable termination head of 66kV and above electric pressure is oil-filled insulator cable end both at home and abroad.
The characteristics of tradition outdoor terminal are that interior external insulation is handled respectively, and external insulation is a porcelain bushing, and prefabricated stress cone control electric field is adopted in interior insulation, fills silicone oil or polyisobutene and so on insulating oil in the sleeve pipe.The problem that the filling insulating oil brings in the sleeve pipe is a lot, will irritate insulating oil in the sleeve pipe, causes the upper-lower seal complex structure, and sealing will be in case inefficacy will cause situations such as insulating oil makes moist, water inlet, leakage of oil to take place; Rubber stress cone directly contacts with insulating oil in some terminal, stress cone swelling in insulating oil that rubber is made, cause stress cone lax, the acceleration stress cone is aging, carbon black in the stress cone semi-conductive screen is separated out in insulating oil, cause electric field distortion, quicken the insulation oil deterioration, these problems are repeatedly all having discovery in the accident.Promptly, refill insulator, be full of insulating oil after the sealing at cable insulation overcoat upper stress awl.Insulator tubular type terminal needs the job site to water insulating oil oil in sleeve pipe again, need fastening high-voltage terminal end seal and radome cap after irritating well, on the one hand, at present the liquid that uses is present in needs sealing to prevent that oil or gas leakage from causing being in operation electric puncture to take place in the insulation, owing to this precedent is arranged, may discharge toxic gas when the liquid that some are flammable electric arc occurs in inside.This terminal is installed complicated, and the engineering time is long, and the factor that product quality is influenced by installation process is more, and during the leakage of the dielectric in the sleeve pipe, easily has an accident, and environment is polluted.In addition, the heavy inconvenience transportation of porcelain bushing, the terminal installation in position needs framework platform, the crisp cracky of porcelain bushing matter.See that on the other hand the porcelain insulating overcoat is frangible and heavy, internal flashover occurring or outside puncturing under the condition that causes destroying the blast that to cause danger.And, in the area that earthquake risk is arranged, need special safeguard measure, hurt sb.'s feelings easily during the terminal accident and damage equipment.Along with the deterioration of environment, pollution flashover accident also often has generation, depend merely on the increase creep distance and can not solve the pollution flashover problem, and this cable terminal volume is big, Heavy Weight.
Summary of the invention
The purpose of this utility model provides a kind of in light weight, does not have to leak, and is non-maintaining, do not have and leaks, and easy for installation, explosion-proof performance is good, rigid dry high-voltage cable terminal end simple in structure.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is: a kind of power cable user internal and external terminals, include silicon rubber composite epoxy sleeve pipe, Stress Control body, insulating material, sealing cap and tail pipe, fill insulant one silicon gel in the middle of silicon rubber composite epoxy sleeve pipe and Stress Control body forms one deck polymeric dielectric layer.This insulating material has well electric and mechanical performance, remove the basic demand of satisfying High-Voltage Insulation, also have low viscosity, soft, high anti-tear, high resiliency, good amount of decrease correction performance, the transparent vulcanized rubber of low Young's modulus, high resiliency, soft are to guarantee the cable load variations, and the supplementary insulation interface performance is stable during insulation breathing; High resiliency, high anti-tear when terminal is installed, the interference fit scope is big; Even low viscosity and good amount of decrease correction performance and the feasible very little elastic deformation under powerful external force effect of low Young's modulus, still keep good with the silicon rubber composite epoxy thimble joint of Stress Control body and external insulation, the trouble and worry that the sulfuration back does not have leakage can not cause environmental pollution; Be dry construction after the sulfuration, install, need not water any dielectric when using.Stress cone is as required by the moulding of semiconductive macromolecular material, and with advanced electric Field Calculation software design, optimal design interface electric field makes the tangential field intensity in interface even, and reduces tangential field intensity as far as possible, and the Stress Control body is the silicon rubber injection moulding, and parts are few.Silicon rubber composite epoxy sleeve pipe light weight has excellent explosion-proof performance, and the silicon rubber antifouling property is good.
The utlity model has following advantage: 1, because the termination of Stress Control body and sleeve pipe seals together, this cable terminal does not have oil, no porcelain, is difficult for causing environmental pollution, and in light weight.2, operation maintenance workload is little, and site operation is simpler, and the engineering time is short.3, the product that dispatches from the factory is a silicon gel insulating material for what fill, belongs to dry construction, need not pour into a mould any dielectric, thus stopped the accident that terminal causes because of related causes such as leakages in running, and environmentally safe.4, has good explosion-proof performance, the Shi Buhui that meets accident damage people or equipment.

Embodiment
Present embodiment is made up of silicon rubber composite epoxy sleeve pipe 1, Stress Control body 2, silicon rubber insulation material 3, silicon rubber full skirt 4, sealing cap 5, tail pipe 6, between silicon rubber composite epoxy sleeve pipe 1 and Stress Control body 2, fill silicon gel insulating material 3, form one deck polymeric dielectric layer; Seal by sealing cap 5 and tail pipe 6 respectively at two ends about in the of 2 at silicon rubber composite epoxy sleeve pipe 1 and Stress Control body.Silicon rubber composite epoxy sleeve pipe 1 outer wall is provided with the full skirt 4 with anti-fouling effect.
The terminal overall weight is light, and on-the-spot installation procedure is easy, handles the cable insulation surface by common operation, and cable is carried out stripping, end fitting is inserted in the good cable of stripping again, seals up sealing cap and tail pipe and promptly accuses and finish.
The embodiment of the above is preferred embodiment of the present utility model only, is not to limit practical range of the present utility model with this, so the equivalence that all shapes according to the utility model, structure and principle are done changes, all should be covered by in the protection range of the present utility model.
