Abstract
A gas-liquid constant-temperature cable is armored with a layer of nitrogen-charged metal tubes connected with nitrogen-making equipment and its control system via a liquid nitrogen tank at the cable terminal, the metal tubes are wrapped with an high-temperature anti-fire strip and a protection layer is set outside of the strip, which applies nitrogen-charged metal tubes armored out of a cable to cool the cable at a safety temperature by the nitrogen.
Description
Technical field
The present invention relates to a kind of cable, belong to the CABLE MATERIALS technical field, refer in particular to a kind of liquid gas constant temperature cable.
Background technology
The high-temperature low-pressure cable is generally by the high-temperature material manufacturing at present, cable itself does not have the temperature adjusting facility, and too high or be subjected to the influence of external high temperature when the cable self-temperature, its heat can't in time discharge, cable assembly particularly insulating barrier subjects to destroy, and the cable blast can take place when serious.
Summary of the invention
The present invention is just in order to overcome above-mentioned deficiency; a kind of liquid gas constant temperature cable that can in time take away the cable heat is provided; guarantee the fail safe that cable uses; improve the life-span of cable; the main improvement is at fireproof cable; high-temperature cable or the armoured one deck of other analogous cable fill the nitrogen metal tube; under high-temperature condition, discharge the heat of taking away cable and reach the constant temperature purpose by filling nitrogen in the nitrogen metal tube; specifically implement like this: liquid gas constant temperature cable; it is characterized in that the armoured one deck of cable fills the nitrogen metal tube; the described nitrogen metal tube that fills is connected system nitrogen instrument and control system thereof by the liquid nitrogen container of cable termination; fill the outer wrapped fire resistant band of nitrogen metal tube, fire guard is provided with protective layer outward in addition.When cable itself produces heat or cable surface and is subjected to temperatures involved, when if cable temperature surpasses set point, automatically operate by control system, nitrogen is poured the cooling that circulates in the metal tube, thereby guarantee the good temperature constant state of cable, the present invention selects the diameter of cooling copper tube and uses radical according to the size of the cross-section of cable.
The cable that the present invention adopts armouring to fill the nitrogen metal tube can be fireproof cable, high-temperature cable or other analogous cable, and filling the nitrogen metal tube preferably is seamless copper pipe, also can be steel pipe, compo pipe etc.
The present invention adopts at the armoured nitrogen metal tube that fills of cable, can cool off the too high temperature of cable by nitrogen, and cable is in the safe temperature all the time, has guaranteed the fail safe of cable, and be improved its useful life.
