本発明はガス封入電磁誘導機器のガス冷却装置の改良に
関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to improvements in gas cooling devices for gas-filled electromagnetic induction equipment.
一般に、ガス封入電磁誘導機器は鉄心及びコイル等より
発生する熱によつて封入ガスの温度が上昇するため、別
に設けたガス冷却装置によつてガスが冷却される。Generally, in a gas-filled electromagnetic induction device, the temperature of the filled gas rises due to heat generated from the iron core, coil, etc., so the gas is cooled by a separately provided gas cooling device.

においては、横寸法Ｙが夫々大きくなる。This gas cooling device is normally attached to the outer box of a gas-filled device, but this outer box is deformed due to an increase in internal pressure due to gas volume expansion due to generated heat. Therefore, various considerations have been made in the past to prevent the influence of this deformation from affecting the cooling device.
For example, a conventional direct cooling type gas insulated transformer equipped with a cooler will be explained. 1 and 2, a gate valve 1 is attached to one side of the outer box 11 of the gas insulated transformer.
Attach the gas blower 14 through the gas blower 2, and connect the connecting pipe 1 to it.
6 and a flexible tube IT to connect the gas cooler 18;
This gas cooler 18 has a support member 19 attached to the outer box 11.
supported by the flexible tube 1? A gas cooling device 22 is configured which is connected to the other side of the outer box 11 by the connecting pipe 16 and the gate valve 12 to form a gas cooling path. As the internal pressure of the outer box increases, the side plate of the outer box 11 deforms as shown by the dotted line in the figure, and this deformation acts as an external force on the gas cooling device 22, putting strain on the connections in this path, causing the gas Gas cooler 1 may cause accidents such as leakage or damage.
Expandable flexible tubes 11 are disposed before and after the gas cooler 8 to absorb this deformation and prevent it from affecting the gas cooler 18. However, flexible tubes 1 before and after the gas cooler 18
7, the vertical dimension Z as shown in FIG. 1 and the horizontal dimension Y as shown in FIG. 2 become larger.

とである。However, most gas insulated transformers are installed in building substations or in power generation substations that are combined with other gas insulated equipment to reduce the size of the site, and in order to be compatible with these , reduction in external dimensions, transportation dimensions, and weight are essential conditions. Therefore, the conventional gas cooling device for a gas insulated transformer has a drawback in that it does not satisfy the above-mentioned essential conditions. The present invention has been made in consideration of the above points, and its purpose is to reduce the external force transmitted to the gas cooler, reduce the piled-up space around the outer box, and reduce the weight. An object of the present invention is to provide a gas cooling device for gas-filled electromagnetic induction equipment.
以下本発明を図面に示す実施例を参照して説明する。The present invention will be described below with reference to embodiments shown in the drawings.

It is connected to the other side of the outer box 11 to form a gas cooling path,
A gas cooler 18 is supported by a support member 19 attached to the outer box 11 with a buffer member 20 such as an elastic body such as vibration isolating rubber or a spring interposed therebetween, thereby forming a gas cooling device 22. Note that the support member 19 may be fixedly attached to a foundation different from the outer box 11. As shown in FIG. is established between.

誘導機器のガス冷却装置を提供することができる。One side of the gas cooling device, the upper side in the illustration, is fixedly attached to the outer box. Therefore, the deformation of the outer box due to the change in the internal pressure of the outer box also affects the gas cooling device, but the effect of this deformation is absorbed by the flexible tube 17. Since the effect of displacement is also absorbed by the shock absorbing member 20 such as anti-vibration rubber, the effect of displacement due to deformation of the outer box does not affect the gas cooling device 22, and gas leakage from the gas cooling device 22 is prevented. It can be prevented. Further, the vertical dimension Z'' in the case of the present invention is smaller than the vertical dimension Z in the conventional case, and the lateral dimension Y is also smaller than the lateral dimension Y. Therefore, the gas cooling of the present invention The size and weight of the device are reduced.As explained above, according to the present invention, a flexible tube is attached to one place in the gas cooling path of the gas cooling device attached to the outer box, and the gas cooling device is By supporting the gas cooling path through the buffer member, the external force applied to the gas cooling path due to the deformation of the outer box is absorbed by the flexible tube and the buffer member, preventing gas leakage, reducing dimensions and weight. It is possible to provide a gas cooling device for a gas-filled electromagnetic induction device that can reduce the amount of heat generated.
