Abstract
The invention relates to an anti-radiation high-voltage cable which comprises an internal conductive layer (1) and an external anti-radiation layer (2). The anti-radiation high-voltage cable is characterized in that the external anti-radiation layer (2) is prepared from carbon fiber and lead alloy fiber in a weaving manner; a wrapping layer (3) is added outside the external anti-radiation layer (2); the wrapping layer (3) is made of a rubber material. By adopting the anti-radiation high-voltage cable provided by the invention, the radiation of a high-voltage cable of a transformer substation to the surrounding residents can be effectively alleviated, and the detection result shows that the anti-radiation property of the cable is increased by more than 2 times when being compared with that of an ordinary high-voltage cable.
Description
Technical field
The present invention relates to a kind of high-tension cable, particularly relate to a kind of radiation-resistant high-tension cable.
Background technology
High-voltage line, refers to the power transmission and transformation line of voltage more than more than 380V.The electric pressure of China ultra-high-tension power transmission line is generally divided into: 35KV, 110KV, 220KV, 330KV, 500KV, 750KV etc.High voltage power transmission generally adopts the cable underground of tape insulation layer to transmit in city, often adopt the overhead wire mode of steel tower carrying to transmit in the wild.People find after studying for a long period of time, because high-voltage line generates an electromagnetic field around it, can produce adverse effect to neighbouring people.The conclusion of Britain's epidemic indagating person: its leukaemia incidence of disease of children lived under electromagnetic radiation is 1/700th, exceeds one times than the child morbidity (1/1400th) living in electromagnetic-radiation-free.This depends mainly on electromagnetic field intensity.People touch electromagnetic field intensity when reaching 50 ~ 200 kilovolts/meter, can occur headache, dizzy, tired, poor sleep, poor appetite, blood, cardiovascular system and central nervous system exception etc.
There is certain regulation in general country to the operating area of high-voltage line and mounting means, and its object is exactly the secondary harm in order to effectively prevent high-tension cable from causing.But because the resident that stays in high voltage substation annex or power plant maintenance personnel inevitably need to face radiation for a long time, safe distance can not effectively be protected, therefore a kind of high-tension cable having more low radiance being applied in high voltage substation is invented, significant.
Summary of the invention
The object of the invention is to, in order to overcome above-mentioned defect, invent a kind of radiation-resistant high-tension cable.
The technical scheme that the present invention takes is: a kind of radiation-resistant high-tension cable, comprises internal electrically conductive layer and outside radiation protective layer, and described outside radiation protective layer adopts carbon fiber and lead alloy fibrage to form.
Further, the outside of described outside radiation protective layer also needs to add a coating layer, and described coating layer is elastomeric material.
Beneficial effect of the present invention: the cable of this product effectively can reduce the radiation of high-tension cable to surrounding resident of transformer station, through detecting, its radiation protection ability will improve more than 2 times than general ordinary high pressure cable.
Accompanying drawing explanation
Fig. 1 is the profile of radiation proof cable of the present invention.
Embodiment
See Fig. 1, high-voltage line of the present invention, mainly comprises internal electrically conductive layer 1 and outside radiation protective layer 2, and wherein innovation is that outside radiation protective layer 2 adopts carbon fiber and lead alloy fibrage to form.Because the radiation proof equivalent of lead is very large, effectively can prevent electromagnetic radiation, carbon fiber has good extension and heat resistance, can lead alloy fiber composite together after, extraordinary Comprehensive Preventing radiance can be played.Effectively can reduce the amount of radiation of high-voltage line to surrounding resident of transformer station.In addition, also need to add a coating layer 3 in the outside of outside radiation protective layer 2, be used for grease proofing and anti-puncture.Also be used for isolating described outside radiation protective layer 2 simultaneously.Coating layer 3 can select general cable elastomeric material, so that cost-saving.
Claims (2)
1. a radiation-resistant high-tension cable, comprises internal electrically conductive layer (1) and outside radiation protective layer (2), it is characterized in that, described outside radiation protective layer (2) adopts carbon fiber and lead alloy fibrage to form.
2. the radiation-resistant high-tension cable of one according to claim 1, is characterized in that, the outside of described outside radiation protective layer (2) also needs to add a coating layer (3), and described coating layer (3) is elastomeric material.
