Abstract
The invention discloses a composite material shielding power cable. The composite material shielding power cable is divided into two classes including the single-core cable and the multi-core cable, the single-core cable is wrapped by an insulating layer, and the insulating layer is wrapped by a composite material shielding layer; the multi-core cable is characterized in that a shielding layer is arranged outside each core wire insulating layer; or a shielding layer is arranged in a protection layer; or shielding layers are arranged outside the insulating layer and in the protection layer at the same time. The composite material shielding power cable is simple in structure, and the shielding materials are light; meanwhile, the anti-electromagnetic interference capacity of the cable can be effectively improved, potentials can be balanced, power supply quality can be improved, and electromagnetic environment influences generated by electrification wires can be reduced.
Description
Technical field
The present invention relates to power cable field, especially the power cable based on composite material shielding.
Background technology
Along with Chinese Urbanization, industrialization, informationalized development, people grow with each passing day to electricity needs.Power cable is mainly used in transmission and distributes the cable of electric energy, is usually used in lead line, the submarine transmission line of underground electrical network, power station and transformer station, the inside power supply circuit of industrial enterprise.Power cable is the cable product in order to transmission and distribution high-power power in the main line of electric power system, comprising the various insulated power cables of 0 ~ 500kV and above.
Existing power cable is made transmission of electric energy and is used in AC and DC power circuit, conventionally anti-electromagnetic interference capability a little less than, forceful electric power is especially obvious to the interference of light current.Some use the cable of woven wire shielding, and cost is higher, and cable weightening finish is larger.
The present invention, except possessing the electricity characteristic of common plastics power cable, also has the characteristic that lowers electromagnetic interference, anti-lightning and balanced current potential, improves power supply quality, is more suitable for high-level environmental demand.In addition, cable weightening finish is less, cost is lower, can be widely used in the places such as Urban Underground electrical network, the common pipeline of forceful electric power light current, electric power machine room, computer center, Surveillance center.
Summary of the invention
The present invention is mainly by adding composite material screen on cable insulation surface, realize the function of shield electromagnetic, can effectively reduce the impact of electromagnetic environment to external world of circuit, prevent the interference of forceful electric power to light current, for electric power system, machine room, equipment center etc. provide the shielded type cable of lightweight.
Composite material shielding power cable is made up of conductor, insulating barrier, screen, is divided into single core and multicore cable two classes.At insulating layer of conductor, composite material screen is set outward, screen is synthetic by composite shielding material mixed polymer emulsions such as nano carbon particle, nano-graphene, ferroferric oxide particle, carbonyl iron nickel particle, carbonyl nickel particulate, carbonyl iron particulate and iron granules.Polymer emulsion is the one in styrene-acrylate copolymer emulsion, pure acrylate emulsion or vinyl acetate-acrylate copolymer emulsion, polyurethane or epoxy resin.Insulating barrier adopts the one in polyvinyl chloride, polyethylene, crosslinked polyethylene, foamed polyethylene, fluoroplastics, polyamide, polypropylene and polyester plastics.Single core shielded type cable is that a cross section is that circular conductor is enclosed with insulating barrier, screen outward successively; The insulating barrier that the every core shielded type cable of multicore is every heart yearn arranges screen outward; In the outer layer protective sleeve that the outer shielded type cable of multicore is split conductor, add composite shielding material and form the shielding protection layer with function of shielding.Dual shield cable is that the insulating barrier of every heart yearn of split conductor arranges screen outward, and in outer layer protective sleeve, adds composite shielding material.
The present invention, by adopting above technical scheme, has reached following beneficial effect:
1. can effectively reduce the electromagnetic field impact of environment to external world that in wire, electric current produces;
2. effectively shield external electromagnetic signal, strengthen the antijamming capability of wire;
3. there is good anti-electromagnetic radiation function, reduce environment pollution with electromagnet;
4. be lighter than metal sheathed cable.
