環して冷却するか、または、終端箱上部に大きなラジェ
ータを設置して大気により自然冷却して循環させる方法
が用いられていた。Conventional forced cooling type cable cable terminal connections either require an external drive source such as a circulation pump to forcefully circulate the oil inside, or install a large radiator on top of the termination box. The method used was to naturally cool and circulate the air using the atmosphere.
従って、ポンプを用いるには動力源が必要であり、故障
もおこし易い。また、終端箔上部に大きなラジェータを
設置するには碍管の強度上の問題があり、別に支持用の
碍子が必要となるなどの難点があった。Therefore, a power source is required to use the pump, and failures are likely to occur. Furthermore, installing a large radiator above the terminal foil poses problems in terms of the strength of the insulator, and requires a separate insulator for support.

ものである。The present invention provides a termination box for a cable in which a cable end is supported on a central axis of an insulator tube, an inner insulating cylinder is provided in a space between the inner wall of the insulator tube and the cable, and the box is filled with insulating oil.
A small radiator for circulating the insulating oil is provided in the upper part of the insulator tube, and a radiator or a heat exchanger for cooling the insulating oil is provided in the lower part.

(stress cone), 5 is a small radiator, 6 is a radiator or heat exchanger, 7 is an oil stopper, 8 is an insulating oil, and 9 is an internal isolation cylinder. In this embodiment, the insulator tube 1 has a wobble end 2 on its central axis, and the space between the inner wall of the insulator tube 1 and the cable body 2 is provided with an inner insulating tube 9 filled with insulating oil 8. 1
Circulate insulating oil 8 to the JL section of 1! - A small radiator 5 is installed to cool the insulating oil 8 to the steel pipe section at the bottom of the insulator tube 1.
The radiator 5 is a light radiator with a small heat transfer area that causes convection and serves as a power source for natural circulation. It is.

入し再冷却されろ。Therefore, the structure is designed to reduce the flow resistance of the insulating oil 8 as much as possible.The insulating oil 8 is cooled by natural cooling or by using a radiator or heat exchanger 6 to cool the insulating oil 8 flowing out from the bottom of the insulating pipe 1. The refrigerant used to cool the cable body is used to cool the cable body by exchanging heat in a controlled manner, and then flows into the bottom of the steel pipe at the bottom of the insulator tube 1, and by the natural circulation action of the radiator b, the inner side is cooled as shown by the arrow. It flows upward through the inside of the insulating tube 9, passes through the radiator 5, and descends from the 91 side of the inner insulating tube 1); it then flows into the heat exchanger 6 and is recooled.
