要とされていた。 A cooling power transmission system that increases power transmission capacity by cooling CV cables is needed as a system for transmitting power to metropolitan areas where the demand for power is significant.
As a cooling method for CV cables, a three-phase system is installed inside the steel pipe.
Evaporative cooling type CV that stores CV cables and refrigerant pipes for transporting liquid refrigerant all together and cools them by filling evaporative refrigerant under pressure around the CV cables.
A cable system is best. On the other hand, the connecting steel pipe that stores the connecting part has a larger diameter than the cable steel pipe that stores the CV cable, and the evaporative refrigerant flow rate due to the large diameter in the gas stop joint that is equipped with a partition plate to cut off the evaporative refrigerant. Effective cooling of CV cables or connections is required because slowdowns occur and stagnation of evaporative refrigerant occurs, causing localized temperature increases in CV cables or connections, reducing power transmission capacity.

FIG. 1 shows an embodiment of the present invention, in which a CV cable 1 and a refrigerant pipe 2 are housed together in a cable steel pipe 3, and a CV
An evaporative refrigerant 4 such as Freon R-11, R-12, SF6 , etc. for cooling the cable 1 is filled under pressure. A connecting portion 6 of the CV cable 1 is housed in a connecting portion steel pipe 5 that communicates with the cable steel pipe 3. A liquid permeable layer 7 is provided around this connecting portion 6 and the CV cable 1 in the vicinity thereof. The liquid-permeable layer 7 is made of a material that easily absorbs the fluid of the evaporative refrigerant 4, such as sheet-like or tape-like nonwoven fabric, cellulose paper, liquid-swellable resin, glass fiber, plastic fiber, or the like. The liquid permeable layer 7 absorbs the liquid of the evaporative refrigerant 4 in the joint steel pipe 5 and maintains the surface of the joint 6 and the CV cable 1 in the vicinity at a temperature determined by the evaporation pressure inside the joint steel pipe 5. be. In this way, the inside of the connecting steel pipe 5 is kept at a constant temperature by the liquid permeable layer 7, thereby preventing a local temperature rise. In addition, the connection steel pipe 5
The illustrated partition plate 8 may be provided inside the connecting portion 6 to disconnect the connection portion 6 from the evaporative refrigerant 4, or the present invention may be applied to a conventional type connection portion without the partition plate 8. Furthermore,
9 is a refrigerant bypass pipe, and 10 is an evaporative refrigerant bypass pipe.
