Abstract
A kind of high-voltage power cable used for electric vehicle, include conductor, semiconductive conductor shield, insulating barrier, double shield layer and sheath, described double shield layer is made up of aluminium plastic membrane layer and braid, and described conductor, semiconductive conductor shield, insulating barrier, aluminium plastic membrane layer, braid and sheath are radially arranged successively from inside to outside.The utility model cable conductor forms by multiple conducting wires is stranded, and easily form air gap between it and insulating barrier, conductive surface is rough, and electric field can be caused to concentrate.Add the screen of one deck semiconductive material at conductive surface, the conductor equipotential of it and conductively-closed and with insulating barrier good contact, thus avoid that electric field occurs between conductor and insulating barrier and concentrate, play the effect of uniform electric field distribution.In cable Long-term bend situation, effect is more remarkable especially.
Description
(1) technical field
The utility model relates to automobile cable technology, specifically uses 3000V high-voltage power cable in a kind of electric automobile.
(2) background technology
In high-flexibility anti-interference battery cable for new energy vehicle (patent No.: ZL200920256779.8), New-energy electric vehicle car inner high voltage power cable electric pressure disclosed in the existing patents such as new-energy automobile motor cable (patent No.: ZL201220345244.X) is generally 1500V and following, higher electric pressure power drive is then needed for the extraordinary vehicle of some high-powers, therefore have and propose the cable that electric pressure reaches 3000V, the specification of cable is relatively large simultaneously, and be required to meet long-term highly bending (bending close to 90 degree) application requirement.The structure of current electric automobile inner high voltage cable fully can not meet application requirement, there is larger electrical safety hidden danger.
(3) summary of the invention
The technical problems to be solved in the utility model is to provide in electric automobile with high voltage height current-carrying power cable, by scientific and reasonable semiconductive conductor screen structural design, shielding material type selecting and technical study, substantially increase bending property and the safety in operation of cable, meet products application technical requirement.
For this reason, the utility model takes following technical scheme:
A kind of high-voltage power cable used for electric vehicle, include conductor, semiconductive conductor shield, insulating barrier, double shield layer and sheath, described double shield layer is made up of aluminium plastic membrane layer and braid, and described conductor, semiconductive conductor shield, insulating barrier, aluminium plastic membrane layer, braid and sheath are radially arranged successively from inside to outside.
Described conductor is annealing bare copper conductor or zinc-plated annealed copper conductor.
Described semiconductive conductor shield adopts thermoplasticity or thermosetting semiconductive elastomer, is closely extruded on conductor.
Described insulating barrier adopts thermoplasticity or thermo-setting elastomer, is closely extruded on semiconductive conductor shield.
Described aluminium plastic membrane layer is close to the vertical bag of insulation by single or double aluminum-plastic composite membrane or is wrappedly formed.
Described braid adopts tin-plating round copper wire or naked circular copper wire braiding composition, and braid closely covers the outer surface of aluminium plastic membrane layer.
Described sheath adopts thermoplasticity or thermo-setting elastomer, and sheath should closely be extruded on braid.
The utility model has the advantages that:
1, cable conductor forms by multiple conducting wires is stranded, and easily form air gap between it and insulating barrier, conductive surface is rough, and electric field can be caused to concentrate.Add the screen of one deck semiconductive material at conductive surface, the conductor equipotential of it and conductively-closed and with insulating barrier good contact, thus avoid that electric field occurs between conductor and insulating barrier and concentrate, play the effect of uniform electric field distribution.In cable Long-term bend situation, effect is more remarkable especially.
2, add one deck semiconductive conductor shield, the damage to insulation when avoiding the long-term overbending of cable, neither affects the flexibility of cable product, bending techniques requirement when meeting again product practical application.
(4) accompanying drawing explanation
Fig. 1 is the utility model structure cross-sectional schematic;
Wherein, 1-conductor, 2-semiconductive conductor shield, 3-insulating barrier, 4-aluminium plastic membrane layer, 5-braid, 6-sheath.
(5) specific embodiment
With reference to accompanying drawing 1, a kind of high-voltage power cable used for electric vehicle, include conductor 1, semiconductive conductor shield 2, insulating barrier 3, double shield layer and sheath 6, described double shield layer is made up of aluminium plastic membrane layer 4 and braid 5, and described conductor, semiconductive conductor shield, insulating barrier, aluminium plastic membrane layer, braid and sheath are radially arranged successively from inside to outside.
Described conductor is the 6th class annealing bare copper conductor meeting GB/T3956 requirement.Described semiconductive conductor shield adopts thermoplasticity semiconductive elastomer, is closely extruded on conductor.Described insulating barrier adopts TPE-S type thermoplastic elastomer (TPE), is closely extruded on semiconductive conductor shield.Described aluminium plastic membrane layer is close to insulating barrier by one side aluminum-plastic composite membrane and is indulged bag and form, and the vertical bag rate of putting up is not less than 15%.Described braid adopts the naked circular copper wire braiding composition meeting GB/T 3953 and specify, braid closely covers the outer surface of aluminium plastic membrane layer.Count is not less than 80%.Described sheath adopts TPE-S type thermoplastic elastomer (TPE), and sheath is closely extruded on braid.
Run under can meeting long-term 3000V high voltage with 3000V high-voltage power cable in the electric automobile made in case study on implementation, product has good flexibility, and bending radius can reach the outside diameter of cable of 6 times.The electrical security that product Long-term bend uses is high.
