Abstract
The invention discloses an intelligent tensile resistant double-waterproof anticorrosive power cable; and the power cable comprises a plurality of cable cores, an internal waterproof packing layer, a metal wire armored layer or a carbon fiber composite filament and an external waterproof layer which are sequentially arranged outside the cable cores. The metal wire armored layer is arranged in an external cover layer of the power cable and can be used for enhancing the anti-tensile strength of the power cable and resisting the destruction of certain geological disasters. Light units are uniformly arranged in the middle of the metal wire armored layer or the carbon fiber composite filament and a plurality of optical fibers are arranged inside the metal wire armored layer or the carbon fiber composite filament, wherein the optical fibers can play a role in monitoring the interior and the surface of the power cable and enabling the cable to have the self-diagnosis capability on one hand, for instance, when some part inside the cable breaks down, the short-circuiting happens, the optical fibers can timely sense the temperature and transmits the temperature to a detection device, thereby the diagnosis and renovation can be timely and rapidly carried out; and on the other hand, the optical fibers can be used for transmitting information at the same time and plays a role in data communication.
Description
?
Technical field
The present invention relates to a kind of power cable, particularly a kind of dual water-tight corrosion-proof power cable of intelligent stretching resistance that has stretching resistance, autodiagnosis and have data communication.
Background technology
9.0 grades of earthquakes of Richter scale take place and cause tsunami in marine site, Japanese northeast on the 11st March in 2011, cause land subsidence, underground structure destroys, and 1～No. 4 unit of Fukushima nuclear power station is damaged, because cable breaks down the cooling system of the inside can't normally be moved simultaneously, cause taking place the nuclear leakage accident.This shows, what stretching resistance, the waterproof anti-corrosion performance of raising water-proof cable resisted this type of geological disaster is very necessary, if cable has certain autodiagnosis ability, can in time find the place of breaking down, just can faster and better repairing and remedial measure.
General water-proof cable all is waterproof or a water stop function of considering cable, make it to be tending towards to improve or change waterproof materials and method to reach the purpose that strengthens the cable waterproof ability, consider that seldom water-proof cable is except waterproof is its main performance, whether can resist certain geological disaster, can in time find apace and autodiagnosis when whether cable breaks down or is damaged in the process of installation or transmission of electric signals, whether can allow the cable also can transmitting optical signal when transmission of electric signals in addition, just transmit information, have certain communication role.Cable intelligent, Mobyneb is the development trend of following cable, also and the policy of the construction intelligent grid carried out of now many in the world countries and regions match.
Summary of the invention
The objective of the invention is to consider less to intelligent, multifunction at present water-proof cable, and deficiency to tensile strength and the certain geological disaster consideration of opposing, the dual water-tight corrosion-proof power cable of a kind of intelligent stretching resistance is proposed, it not only has multiple water-proof function, and tensile strength strengthens and can resist the destruction of certain geological disaster; Also make common water-proof cable have the function of autodiagnosis and transmission information simultaneously.
The dual water-tight corrosion-proof power cable of intelligent stretching resistance of the present invention, it comprises some cable cores, and is successively set on the outer inner waterproofing packed layer of cable core, and wire armour or carbon fiber composite filament and exterior waterproof coating.Wire armouring or carbon fiber composite filament are set in the outer jacket of cable can strengthen the tensile strength of cable and the destruction of the certain geological disaster of opposing.
Light unit and built-in some optical fiber evenly are set in the middle of wire armour or carbon fiber composite filament, its role is to: the one, can play certain supervisory function bit to cable inside and top layer, make cable have the ability of autodiagnosis, for example when short circuit will be broken down in cable somewhere, the inside, optical fiber can in time be responded to temperature herein and be transferred in the checkout equipment, is convenient in time, diagnoses rapidly and repairs; The 2nd, optical fiber energy transmission simultaneously information plays the effect of data communication.
The structure of cable core is: outwards be followed successively by conductor by the center, conductor shield, insulating barrier, insulation screen, semiconductive waterstop, metal block water and overlap and semi-conductive tape.The present invention has taken into full account the waterproof anti-corrosion performance of cable, semiconductive waterstop and the metal cover that blocks water is arranged between the insulation screen of cable and semi-conductive tape, inner waterproofing layer and outer anticorrosion watertight composition are arranged respectively again inside and outside the armour of sheath, multiple waterproof, make the water resistance of cable very superior, the waterproof effect highly significant.
Description of drawings
Fig. 1 is the structural representation of the present invention of single cable core,
Fig. 2 is the structural representation of the present invention of many cable cores.
Embodiment
Referring to Fig. 1, the present invention is the dual water-tight corrosion-proof power cable of intelligent stretching resistance, and its structure outwards is followed successively by conductor 1 by the center, conductor shield 2, insulating barrier 3, insulation screen 4, semiconductive waterstop 5, metal blocks water and overlaps 6, semi-conductive tape 7, inner waterproofing packed layer 8, wire armour or carbon fiber composite filament 9, light unit (built-in some optical fiber) 10, exterior waterproof coating 11.Wherein add 6 evenly distributed light unit in wire armour or the carbon fiber composite filament, wherein the fiber number in every light unit is preferably 1,2,4,6,12,18,20,24,30,36,48,60,72,84 or 96 cores, also can be other core numbers of customer requirements.
Fig. 2 is dual water-tight corrosion-proof three core power cables of intelligent stretching resistance, and its structure is formed similar to single cable core structure.
The above only is a preferred implementation of the present invention, should be pointed out that for those skilled in the art, under the prerequisite that does not break away from the principle of the invention, can also make some improvement, and these improvement also should be considered as protection scope of the present invention.
