Abstract
The utility model relates to a low-carbon environment-friendly gas insulated power cable which comprises an inner conductor. The low-carbon environment-friendly gas insulated power cable is characterized in that an inner conductor is positioned in a cylindrical outer conductor and connected with an outer conductor through supporting insulators, and a cavity between the inner conductor and the outer conductor is filled with insulating gas; the inner conductor is a solid inner conductor; the inner conductor is a tubular inner conductor; the inner conductor is a stranded conductor, i.e., a composite inner conductor wrapped with a closing layer outside; through holes are formed on the supporting insulators respectively; the insulating gas is nitrogen; and an anticorrosive coating is coated outside the outer conductor. The low-carbon environment-friendly gas insulated power cable has the main characteristic that since the renewable nitrogen is adopted as the insulating gas, the cable is high in insulating property, long in service life and good in recoverability of the cable material; since only fewer supporting insulators and the anticorrosive coating of the outer conductor as the organic materials are adopted in the entire cable structure, the cable has the characteristics of low carbon, environmental protection and energy conservation; and since lots of nitrogen exists in air, no pollution and damage are caused even if nitrogen leaks in the atmosphere due to destroy during the use of the cable.
Description
Technical field
The utility model relates to a kind of low-carbon environment-friendly gas-insulated power cable, belongs to the cable technology field.
Background technology
At present, the various power cables outside of many extensive uses at home all comprises carbon containings such as a large amount of XLPE, PVC, EPR by employing organic insulating material is realized the insulation between cable conductor, these insulating material need consume a large amount of resources such as oil, these organic materials can discharge harmful poisonous materials such as a large amount of carbon dioxide, hydrogen halides when burning simultaneously, influence the safety of people's life, also can serious environment pollution.The power cable of a kind of low-carbon energy-saving Environmental Safety of innovative design is the requirement to the cable scientific worker.
Summary of the invention
The task of the utility model patent is the power cable that high performance low-carbon (LC), energy-saving and environmental protection will be provided, can effectively solve in the prior art to use and more consume the bulk petroleum resource such as organic insulation such as XLPE, PVC, these organic materials can discharge harmful poisonous materials such as a large amount of carbon dioxide, hydrogen halides when burning when fire takes place simultaneously, influence the safety of people's life, also can serious environment pollution etc. factor.The utility model designs a kind of low-carbon environment-friendly gas-insulated power cable, comprise inner wire, it is characterized in that: inner wire is positioned at the outer conductor of tubular, is linked to each other with outer conductor by support insulator, and being full of in the cavity between inner wire and outer conductor has insulating gas.Inner wire is solid inner wire.Inner wire is the tubulose inner wire.Inner wire is a stranded conductor, is coated with the compound conductor of confining bed.Through hole is arranged on the support insulator.Insulating gas is a nitrogen.Outer conductor is coated with anticorrosive coat outward.One of main feature of the present utility model is that product has adopted reproducible nitrogen as insulation, the insulation property height of cable, long service life, the recovery of cable material is good, it is organic material that the whole construction of cable has only a spot of support insulator and outer conductor anticorrosive coat, have the energy-conservation characteristics of low-carbon environment-friendly, nitrogen itself is a large amount of existence the in the air, also can not pollute and damage even take place to destroy in the cable use to be leaked in the atmosphere, the invention has reached the scientific and technical innovation designing requirement of low-carbon (LC), environmental protection, safety non-pollution.Simultaneously because the nitrogen insulation takes place to puncture the back because the pressure and the flowability of gas have self-repairability, even cable conductor is destroyed, re-fill nitrogen insulation after the reparation and still can reuse, therefore have longer useful life, the use of cable can reach more than 40 years even be longer.
Description of drawings
Accompanying drawing is a stereochemical structure generalized section of the present utility model.
Embodiment
Below by accompanying drawing patent of the present invention is introduced.
Comprise inner wire 1 among the figure, it is characterized in that: inner wire 1 is positioned at the outer conductor 3 of tubular, is linked to each other with outer conductor 3 by support insulator 2, and being full of in the cavity between inner wire 1 and outer conductor 3 has insulating gas 4.Inner wire 1 is solid inner wire.Inner wire 1 is the tubulose inner wire.Inner wire 1 is a stranded conductor, is coated with the compound conductor of confining bed.On the support insulator 2 through hole is arranged.The outer conductor 3 outer anticorrosive coats 5 that are coated with.
Described cable inner conductor 1 can or be the compound conductor that stranded conductor coats confining bed outward for solid inner wire, tubulose inner wire, and conductive material generally adopts copper, aluminum or aluminum alloy.
The insulation support body with holes or not with holes that described support insulator 2 is made by high insulating property, high-intensity insulating material, insulating gas is run through in the middle of the internal and external conductor that is full of cable, hole structure not can be used as the support insulator of end, is to be used for the insulating gas shutoff in the middle of the internal and external conductor of two such supporters and cable.
Described cable outer conductor 3 is the cable outer conductors that are coated on the support insulator, and the conductor that its effect can be used as cable uses, and the ground wire that also can be used as cable uses, and it can be aluminium-alloy pipe or copper pipe.
Described insulating gas 4 adopts reproducible pure nitrogen gas as insulation, and pure nitrogen gas has good dielectric property, and can improve its breakdown strength by improving nitrogen pressure, meets the requirements of insulation property.Nitrogen itself is a large amount of existence the in the air, even taking place in the cable use to destroy to be leaked in the atmosphere can not pollute and damage yet, the present invention has the scientific and technical innovation designing requirement of low-carbon (LC), environmental protection, safety non-pollution.Simultaneously because the nitrogen insulation takes place to puncture the back because the pressure and the flowability of gas have self-repairability, even cable conductor is destroyed, re-fill pure nitrogen gas insulation after the reparation and still can reuse, therefore have longer useful life, the use of cable can reach more than 40 years even be longer.Pure nitrogen gas insulation filling method is to be evacuated in the pipeline that will be formed by inner wire, outer conductor, sealing support insulator earlier, then pure nitrogen gas is charged into, and makes nitrogen be full of between internal and external conductor, reaches the purpose of insulation.
The described anticorrosive coat 5 that is coated on the outer conductor is that the outer conductor of prevention cable externally is corroded under the environmental activity, influence its serviceability and life-span, adopt the anticorrosive coat that applies, also can adopt the anticorrosive coat of extruding, do not need also can cancel this anticorrosive coat under the corrosion-resistant condition definite.
