Description
Technical field:
The invention belongs to energized equipment technical field, relate to a kind of shield type flexible cable of Graphene compounded rubber matter, make the shield type flexible cable of multiple structure sheaf with the composite material of Graphene and rubber.
Background technology:
Cable, normally by the similar cord-like cable that the wire (often organizing at least two) of several or several groups mutually insulateds is stranded around a center, and is surrounded by the cover layer of high-insulation, has the feature of interior energising, external insulation in whole outside; Roughly there are the classification such as power cable, control cables, compensating cable, shielded type cable, high-temperature cable, computer cable, signal cable, coaxial cable, fire-resisting cable, shipboard cable, mining cable and aluminium alloy cable, are applied in electric power system, information transmission and instrument system for connecting circuit, electrical equipment etc.The 10KV seen in prior art and above power cable generally have conductor shield and insulation screen, and to reach the effect of homogenizing electric field, and most of shield type rubber flexible cable all adopts semiconducting rubber as screen; Must be very smooth, smooth according to technical requirement screen, if there is the fault of any protrusion, can internal field be strengthened and cause the premature breakdown of the breakdown and cable of insulating barrier.The semiconducting rubber screen seen at present is all prepared from through mechanical mixture by rubber and conductive black, owing to there is the impurity such as burnt grain, refractory material, iron rust in conductive black, and carbon black particle size distribution is uneven etc., and reason causes screen often to occur the flaws such as salient point, we know, Graphene has good machinery, optics, electricity, thermal and magnetic attribute, is also the fastest material of the electron conductivity that finds so far, its electron conductivity 15000cmol/L/ (V.s), size, below 10 microns, can well evenly spread in other materials, see by the related art of Graphene as CABLE MATERIALS although have in practice, such as a kind of modified graphene CABLE MATERIALS disclosed in Chinese patent 201410487326.1, a kind of method preparing Graphene electric wire disclosed in Chinese patent 201310082435.0, it is cut out with through heat treated graphene composite film, curlingly make Graphene electric wire heart yearn, but although above-mentioned technology applies Graphene as CABLE MATERIALS, but not by the setting of structure sheaf to improve the performance of whole cable, therefore, the present invention prepares a kind ofly has smooth surface and the shielded type cable of the good semiconducting rubber matter of conductivity, conductive black and rubber combined is substituted with Graphene, thus realize good conduction and transfer function.
Summary of the invention:
Goal of the invention of the present invention is the shortcoming overcoming prior art existence, seeks the shield type flexible cable designing a kind of Graphene compounded rubber matter, features such as having long service life, safe operation degree is high, resistivity is low, the equal rate of electric field is strong.
To achieve these goals, agent structure from-inner-to-outer of the present invention is followed successively by conductor, conductor shield, insulating barrier, insulation screen, metallic sheath and protection overcoat, outside the conductor of the rope-shaped structure that more than two copper conductor/aluminum conductors are stranded, jacket formula is fitted with the conductor shield of the rubber shape structure of Graphene compounded rubber matter, play the effect of homogenizing electric field, the outside jacket formula of conductor shield adjoins the insulating barrier of 0.3-0.8cm thickness, the outside jacket formula of insulating barrier is fitted with the insulation screen of the rubber shape structure of Graphene compounded rubber matter, to avoid partial discharge phenomenon, the outside jacket formula of insulation screen adjoins the metallic sheath of copper pipe structure, the outside socket joint type of metallic sheath is fitted with the protection overcoat of hollow tube-like structure in rubber mass, increase the overall wear resistance of cable.
The conductor shield that the present invention relates to and insulation screen be structure identical, the rubber combined matter semiconducting rubber of smooth surface, smooth Graphene, in this compound matter semiconducting rubber, the weight percent content of Graphene is 10%-20%; Conductor shield effectively can fill the gap between conductor and insulating barrier, and disperse, homogenizing is rough due to conductor self and the electric field that causes is concentrated, insulation screen effectively can fill the gap between insulating barrier and metallic sheath, to solve partial discharge problem; Insulating barrier is that rubber mass insulating material is made.
The present invention compared with prior art, respectively between conductor and insulating barrier, respectively add the screen of a layer graphene compounded rubber matter between insulating barrier and metallic sheath respectively, to avoid, electric field is concentrated, partial discharge phenomenon, improve shielding and the conductivity of whole cable, substantially increase useful life and the safe operation degree of cable simultaneously; Its structure is simple, and reasonable in design, preparation cost is low, and long service life, security of operation degree are high, environmental friendliness.
