トパイプ方式の箔巻変圧器が考えられている。(Prior Art) A foil-wound transformer has a good winding space factor and can be made smaller and lighter. It has already been put to practical use in small capacity transformers with relatively low voltages of several KV and several hundred KVA. In recent years, in view of its excellent advantages, research has been conducted to expand its application to higher voltage, larger capacity transformers, such as 275 KV and 300 MVA class transformers, but the biggest technical problem is how to improve cooling efficiency and The two issues are whether the winding can have LA insulation ability and whether it can withstand radial mechanical force in the event of a short circuit accident. Such high-voltage, large-capacity transformers have not yet been put into practical use, but as shown in Figure 3, a cooling duct is built into the winding, and a refrigerant with excellent insulation properties is fed into this cooling duct. A heat pipe type foil-wound transformer is being considered, which uses the latent heat of vaporization of a refrigerant to cool the heat generated from winding loss.

A refrigerant such as 13 or Fluorinert FC75 is sealed in the refrigerant, which is circulated by a pump 7, and the heat generated within the winding is absorbed by the latent heat of the refrigerant, and the vapor is cooled and condensed in a condenser 8 through a cooling water pipe 9. ing.

The liquid guide pipe 11 is also connected to the ground potential of the tank 13 and the like. On the other hand, since the cooling duct 6 is built into the winding, it is electrically connected to the same potential as the adjacent winding. Furthermore, the insulation of each part of the winding is ensured by an insulating gas such as SF or gas sealed in the tank 13.

ながら箔巻巻線機１５により巻回する。(Problems to be Solved by the Invention) This type of foil-wound transformer utilizes the latent heat of vaporization of the refrigerant, so it can be expected to have excellent cooling characteristics and is promising for large-capacity, high-voltage transformers. However, even this type of separate type foil-wound transformer has the following problems. This will be explained using the conventional winding device shown in FIG. 2. In FIG. 2, the metal sheet 2 and the insulating sheet 3 are wound by a foil winding machine 15 while applying tension by a brake device 14.

起こす可能性があった。In this case, since the metal sheet 2 and the insulating sheet 3 are spread out in the horizontal direction, dust in the atmosphere at the location where the winding device is installed falls, adheres to the sheet, and is wound into the coil. Insulation between the metal sheet turns is provided by the insulating sheet 3, but the insulating sheet 3 is scratched by these foreign substances, reducing the dielectric strength and reducing the reliability of the insulation between the metal sheet turns. Foil-wound windings manufactured under such conditions suffer from short circuits during voltage application in the early stages of manufacture, deterioration of insulation performance due to aging deterioration during long-term operation, external vibrations,
Alternatively, electromagnetic and mechanical forces generated in the windings may cause a short circuit accident.
