Description
Technical field
The present invention relates to a kind of submarine cable, especially a kind of submarine cable with cooling function, belongs to technical field of electric wires and cables.
Background technology
Submarine cable (undersea cable) is the wire by wrapped with insulation, is laid on seabed, for telecommunication transmission.Submarine cable divides submarine communication cable and sea electric power cable.Modern submarine cable is all to use optical fiber as material, transmission phone and internet signal.The bar submarine cable that beats the world is to lay between 1850 Nian Britain and France.Article one submarine cable of China is to complete in 1888.Submarine cable divides submarine communication cable and sea electric power cable.Submarine communication cable is mainly used in communication traffic, somewhat expensive, but privacy degrees is high.Sea electric power cable is mainly used in transmitting high-power power under water, is equal to the effect of underground power cable, and only the occasion of application is different with the mode of laying.
Submarine cable is owing to being all to transmit under water high-power power at present, and the evolution of heat is understood in the unit that conducts electricity because power is excessive, and these heats are absorbed in the seawater of cable surrounding in seawater, so power consumption is very little.When submarine cable is when being routed to land in the sea, owing to having lacked the cooling of seawater, carry electric loss to increase.Therefore, must lower the temperature to reduce transmission losses to cable.
Summary of the invention
The object of the invention is to overcome above-mentioned the deficiencies in the prior art, a kind of submarine cable with cooling function is provided.
The present invention will solve: existing submarine cable land is laid section and because lowering the temperature, made the problem that transmission losses is large.
For realizing object of the present invention, the technical solution used in the present invention is:
A kind of submarine cable with cooling function, comprise serving, sensing unit, wire armoring layer, transmission of electricity unit, fill main body, inner cushion layer, fiber unit and main body, it is characterized in that: described serving is wrapped in main body outermost layer, described serving inner side is enclosed with wire armoring layer, inner cushion layer and filling main body successively; Described transmission of electricity unit arranges fills in main body, in the middle of described filling main body, is also provided with the passage that blocks water, and the channel setting that blocks water has cold oil.
Described transmission of electricity element number is four, fills in main body each up and down.
The both sides, interior transmission of electricity unit of described filling main body top are provided with sensing unit.
The both sides, interior transmission of electricity unit of described filling main body below are provided with fiber unit.
Described transmission of electricity unit comprises sheath, water blocking layer, insulating barrier, copper strip shielding layer and copper conductor, and described copper conductor is arranged on transmission of electricity unit innermost layer, and outside, transmission of electricity unit is enclosed with insulating barrier, water blocking layer, copper strip shielding layer and sheath successively.
Advantage of the present invention is: by be provided with the passage that blocks water in the middle of existing submarine cable, then carry cold oil in the passage that blocks water, the heat absorption that cold oil is dispersed out by transmission of electricity unit is fallen, and whole cable temperature is declined, and has reduced transmission losses.Therefore, the present invention has advantages of safe and energy consumption is low, has wide market prospects.

In figure: 1, serving, 2, sensing unit, 3, wire armoring layer, 4, transmission of electricity unit, 5, fill main body, 6, cold oil, 7, the passage that blocks water, 8, inner cushion layer, 9, fiber unit, 10, sheath, 11, water blocking layer, 12, insulating barrier, 13, copper strip shielding layer, 14, copper conductor, 15, main body.
Embodiment
Below in conjunction with drawings and Examples, the present invention is further illustrated.
As shown in the figure, the present invention has the submarine cable of cooling function, comprise serving 1, sensing unit 2, wire armoring layer 3, transmission of electricity unit 4, fill main body 5, inner cushion layer 8, fiber unit 9 and main body 15, described serving 1 is wrapped in main body 15 outermost layers, and described serving 1 inner side is enclosed with successively wire armoring layer 3, inner cushion layer 8 and fills main body 5; Described transmission of electricity unit 4 arranges fills in main body 5, in the middle of described filling main body 5, is also provided with resistance water channel 7, and resistance water channel 7 is provided with cold oil 6.
Transmission of electricity unit 4 quantity are four, fill in main body 5 each up and down; 4 both sides, interior transmission of electricity unit of filling main body 5 tops are provided with sensing unit 2 and are used for monitoring circuit, occur damaging and can sense, are convenient to find maintenance; 4 both sides, interior transmission of electricity unit of filling main body 5 belows are provided with fiber unit 9 and are used for transmitting data model.
Transmission of electricity unit 4 comprises sheath 10, water blocking layer 11, insulating barrier 12, copper strip shielding layer 13 and copper conductor 14, described copper conductor 14 is arranged on transmission of electricity unit 4 innermost layers, and transmission of electricity 4 outsides, unit are enclosed with insulating barrier 12, water blocking layer 11, copper strip shielding layer 13 and sheath 10 successively.
When operation is transmitted electricity in transmission of electricity unit 4, the heat that copper conductor 14 in transmission of electricity unit 4 exhales is hindered cold oil 6 absorbing, coolings in water channel 7, main body 15 is subject to the absorbing, cooling of cold oil 6 and can not generates heat like this, and therefore, transmission of electricity unit 4 transmission losses will diminish.
