リ りを生じたりすることがある。Water, oil, fluorocarbons, etc. are used as refrigerants in internal cooling cables (but in the case of large-capacity power transmission cables, the transmission voltage of 66 KV to 500 KV is used as the refrigerant described above). The medium must be insulated by cable hems, cooling junction boxes, etc. However, in the case of non-separate cooling methods, the refrigerant comes into direct contact with the insulators and conductors.
There is a risk that the refrigerant will deteriorate and this will cause deterioration of the insulator. For example, in the case of water cooling, metal ions of the conductor dissolve into the cooling water, significantly degrading the insulator. As a result, ground faults may occur at cables, nodes, and junction boxes.
It may cause rips.

る。In Fig. 1, the refrigerant is Freon, and the gas-liquid mixed phase refrigerant from the cable return 1 passes through one of the drying tanks 2 installed in parallel, where water is removed and the refrigerant is transferred to the reservoir tank 3. accepted. A degraded decomposed gas collecting section 4 is provided at the top of the reservoir tank 3, and a cooling liquefaction radiator 5 is provided at the side thereof. The liquid-phase Freon stored in the tank 3 passes through a heat exchanger 7 and a filter 8 in this order by a pump 6, and is pumped to a cable.

除去される。In the cooling system having the above-mentioned configuration, moisture in the fluorocarbon is removed in the drying tank 2. In addition, degraded decomposed gas is
Since it is not liquefied in the radiator 5 and is lighter than the fluorocarbon gas itself, it is collected in the collection section 4. Therefore, it is possible to open the valve 4a of the collection unit 4 and release it into the atmosphere for removal. Note that solid matter in the refrigerant is removed by the filter 8.

After passing through the drying tank 2, the oil from the cable return 1 passes through the diverter valve 9, the degassifier lO and the bypass 11, and is pumped by the pump 6 to the cable via the heat exchanger 7 and filter 8. be done. The degun fire 10 separates gas by spraying oil into a vacuum. According to this embodiment, moisture and gaseous substances in the oil are removed. Further, wax-like substances and the like caused by deterioration are also removed by the filter 8.
