Description
Technical field
The present invention relates to field of cable technology, particularly relate to a kind of indoor ventilation cooling type cable.
Background technology
Cable is used for transmitting the electric charge of directed movement, has a wide range of applications in fields such as electric power system, the information transmission system and instrument systems.In transmission charge process, because the wire in cable has certain resistance, certain heat can be produced when the current flows, if heat can not be discharged for a long time, then the resistance of conductor can be made to increase on the one hand, produce more heats, the plastic casing aging speed playing insulating effect in cable can be made on the other hand to accelerate, have a strong impact on the useful life of cable.
Summary of the invention
Based on the technical problem that background technology exists, the present invention proposes a kind of indoor ventilation cooling type cable.
The indoor ventilation cooling type cable of one that the present invention proposes, comprising: ventilation duct, one or more core, inner sheath, armour, oversheath and multiple tube connector;
Core is made up of conductor, the first insulating barrier, screen and the second insulating barrier, and the first insulating barrier is coated on conductor periphery, and screen is coated on the first insulating barrier periphery, and the second insulating barrier is coated on screen periphery; Core is looped around ventilation duct periphery and is twisted into cable core with ventilation duct;
Inner sheath is coated on cable core periphery, is filled with heat filling between itself and cable core; Armour is coated on inner sheath periphery, and oversheath is coated on armour periphery;
Ventilation duct be provided with multiple air holes along its length and with multiple tube connector one_to_one corresponding, tube connector first end is communicated with corresponding air holes, and the second end runs through oversheath.
Preferably, ventilation duct adopts Heat Conduction Material to make.
Preferably, extractor fan is provided with in part tube connector.
Preferably, the outer surface of inner sheath is provided with multiple spherical or hemispherical projections.
Preferably, the inner surface of oversheath is provided with multiple spherical or hemispherical projections.
Preferably, the outer surface of oversheath is provided with multiple convex thick stick extended along its length, and the outer surface of convex thick stick is arc.
In the present invention, ventilation duct be provided with multiple air holes along its length and with multiple tube connector one_to_one corresponding, tube connector first end is communicated with corresponding air holes, and the second end runs through oversheath.So, the heat that core produces to be entered in ventilation duct by heat exchange and discharges through tube connector, and the Cryogenic air of Exterior cable enters by tube connector ventilation duct to reach cable cooling effect by the temperature that heat exchange reduces core.
In the present invention, the heat filling of cable core periphery can further improve the heat exchanger effectiveness of core and ventilation duct, improves result of ventilating heat dissipation.
Accompanying drawing explanation
Fig. 1 is the indoor ventilation cooling type construction of cable schematic diagram that the present invention proposes;
Fig. 2 is ventilation duct and tube connector scheme of installation.
Embodiment
With reference to Fig. 1, Fig. 2, the indoor ventilation cooling type cable that the present invention proposes, comprising: ventilation duct 1, core 2, inner sheath 3, armour 4, oversheath 5 and multiple tube connector 6.
Core 2 is made up of conductor 21, first insulating barrier 22, screen 23 and the second insulating barrier 24.First insulating barrier 22 is coated on conductor 21 periphery, and screen 23 is coated on the first insulating barrier 22 periphery, and the second insulating barrier 24 is coated on screen 23 periphery.
Core 2 is looped around ventilation duct 1 periphery and is twisted into cable core with ventilation duct 1.
When the present invention specifically implements, the quantity of core 2 can be one, also can be many.Screen 23 adopts metal wire shielding layer, and it coordinates the first insulating barrier 22 and the second insulating barrier 24, can avoid the signal cross-talk between different core 2 or cable.
Inner sheath 3 is coated on cable core periphery, is filled with heat filling 7 between itself and cable core.Armour 4 is coated on inner sheath 3 periphery, and oversheath 5 is coated on armour 4 periphery.
Ventilation duct 1 be provided with multiple air holes 10 along its length and with multiple tube connector 6 one_to_one corresponding, tube connector 6 first end is communicated with corresponding air holes 10, second end and runs through oversheath 5.So, the heat that core 2 produces to be entered in ventilation duct 1 by heat exchange and discharges through tube connector 6, and the Cryogenic air of Exterior cable enters by tube connector 6 ventilation duct 1 to reach cable cooling effect by the temperature that heat exchange reduces core 2.
In present embodiment, ventilation duct 1 adopts Heat Conduction Material to make, and coordinates the heat filling 7 of core 2 periphery, can improve the efficiency that core 2 and ventilation duct 1 carry out heat exchange.
In present embodiment, be provided with extractor fan in part tube connector 6 to increase air velocity.In addition, the air flow being provided with the tube connector 6 of extractor fan is contrary with the air flow of the tube connector 6 not arranging extractor fan, is conducive to the exchange efficiency increasing ventilation duct 1 and extraneous air.
In present embodiment, the outer surface of inner sheath 3 and the inner surface of oversheath 5 be provided with multiple spherical or hemispherical projections from the surfaces externally and internally of armour 4 carry out against, so, when Exterior cable is squeezed power, cushioned by spherical or hemispherical projections, the impaired or ventilation duct 1 deformation effect ventilation effect of core 2 can be avoided.
In present embodiment, the outer surface of oversheath 5 is provided with multiple convex thick stick extended along its length, and the outer surface of convex thick stick is arc.So, can further improve the anti-extrusion deformation nature of cable.
