Title: Stationary induction electric apparatus
Inventor: SEKIDA SANAE
IPC: H01F27/18
Filed: 1982-11-08
Abstract: PURPOSE:To drastically improve the cooling effect and realize small size and light weight apparatus by providing a liquid guide system comprising a pump between the bottom part of vessel and the liquid tank housing a coil-wound core and the liquid of non-condensable coolant and by disposing a heat exchanger within the vessel. CONSTITUTION:Since the non-condensable gas 20 such as SF6 gas is sealed within the vessel 11 of transformer at the time of starting, electric insulation can be ensured. At the time of operation of a transformer 10, radiated heat of winding 13 within a liquid tank 16 is absorbed by the liquid 15 of condensable coolant and it becomes steam 25 and is vaporized within the vessel 11. However, the reservior 17 and the liquid tank 16 within the vessel 11 are connected through the liquid guide system 19 comprising a pump 18. Therefore, the liquid 15 in the reservoir 17 is supplied by the pump 18 as much as the reduced amount of liquid 15 of the vessel 16. Since the insulation gas is a non-condensable gas 20, heat exchange is not carried out even when it is heated by the steam 25 of condensable coolant. Therefore, the steam 25 of liquid 5 pushes upward in the vessel 11 the insulation gas namely noncondensable gas 20. Accordingly, a large amount of steam 25 of condensable coolant exists at the lower part thereof.
