いた。In the above configuration, the refrigerant liquid 7 supplied to the wedge 5
Is an iron core holder arranged on the two side walls of the tank 3 facing each other.
20 is guided to the iron core 2 through the wedge gap 5a provided in the wedge 5 provided between the coil group 1 and the coil group 1, but the refrigerant liquid 7 supplied to the wedge 5 is scattered on the upper surface of the wedge 5, so that the efficiency is improved. Not often supplied to the gap 5a between wedges. Further, if the orientation of the supply hole 6a of the refrigerant liquid supply duct 6 is different from the design value due to a manufacturing error, the refrigerant liquid 7 may not be reliably supplied to the upper surface of the wedge 5, and thus the refrigerant liquid supply It took a lot of time to assemble the duct 6.

７が効率よく鉄心２面に導くことができなかった。In the conventional evaporative cooling type stationary induction device as described above, when the refrigerant liquid 7 is supplied to the upper surface of the wedge 5, it may scatter,
The supplied coolant liquid 7 could not be efficiently guided to the surface of the iron core 2 due to the difference in the direction of the supply hole 6a.
そのため余分に冷媒液７を供給する必要があり、ひい
ては冷媒液供給ダクト６を大きくしたり、冷媒液７を多
量に要するなどの問題点があった。Therefore, there is a problem that it is necessary to additionally supply the refrigerant liquid 7, the refrigerant liquid supply duct 6 is enlarged, and a large amount of the refrigerant liquid 7 is required.

目的とする。The present invention has been made to solve such problems, and by efficiently guiding the refrigerant liquid to the iron core, it is possible to avoid supplying a large amount of the refrigerant liquid without enlarging the supply duct. The purpose is to obtain a stationary induction device that can.

上面に供給される。With the above configuration, the refrigerant liquid 7 supplied from the refrigerant liquid supply duct 6 is stored on the upper surface of the upper rust 5 by the damming barriers 8a and 8b provided on both surfaces of the upper wedge 5, and then the inter-wedge gap 5a is formed. It flows down and is guided to the iron core 2. Further, since the heights of the barriers 8a and 8b are changed, the refrigerant liquid 7 can be surely kept in the upper duct 5 even if there is some assembly error.
Supplied on the top surface.
