> The flow path is located between the shield gap (
The flow path is divided into the flow path that flows down the side of the iron core on the tank (3> side through 4a) and the flow path that flows down the side of the tank core through the gap between the wedges (5a). The refrigerant liquid (10) flowing through the electromagnetic shield (4b)
It should fall on the top surface, collect in the shield tray (7), and then flow down the side of the tank core through the gap between the shields (4d), but there is a risk that it may flow to both the tank core and the side of the tank side core. , the amount of refrigerant liquid (10) supplied to the tank core may be reduced.As a result, the supply amount had to be increased in order to supply the required amount of refrigerant liquid (10) to the tank core. .

導か、れる。[Problems to be Solved by the Invention] In the conventional stationary induction equipment as described above, refrigerant liquid is not efficiently supplied to the tank iron core, which may cause a local temperature rise in the iron core. There were problems such as the need to supply a large amount of refrigerant liquid to meet the demand. This invention was made to solve these problems, and by efficiently guiding the refrigerant liquid supplied through the gap between the wedges to the tank part iron core, it prevents the local temperature rise of the iron core. Another purpose is to obtain a stationary induction device that can reduce the amount of refrigerant used. [Means for Solving the Problems] The stationary induction device according to the present invention has a damming angle provided on the upper surface of the electromagnetic shield of the tank portion. [Function] In this invention, between the wedges l1! Due to the dam angle, the refrigerant liquid that flows between the tanks does not flow to the tank side iron core, so all of it is collected in the shield tray and guided to the tank side iron core.

A damming angle (9) with a> is provided. The notch (9a) of the dam angle (9) is aligned with the liquid passage spacer (6) and the insulating angle (8). The same reference numerals as in Figs. 1 to 6 indicate the same parts. With the above structure, the refrigerant liquid (10) flowing down from the upper part of the tank (3>
When it falls on the upper surface of the electromagnetic shield <4b>, the entire amount is removed by the dam angle (9>).
), and is then guided through the inter-shield gap (4d) to the tank part of the iron core (2>) and flows down the side of the iron core.
If there is no dam angle (9), the gap between the wedges (5a
) A part of the refrigerant liquid (10) flowing down the side of the iron core on the tank (3) side was flowing down the side of the iron core on the side of the tank (3). The entire amount flows down the side of the tank core. [Effects of the Invention] As is clear from the above description, the present invention provides a damming angle on the upper surface of the electromagnetic shield of the tank section, thereby making it possible to efficiently guide the refrigerant liquid to the tank section iron core and cause it to flow down. As a result, it is possible to prevent a local temperature rise in the iron core, and also to reduce the supply amount of refrigerant liquid, thereby reducing the amount used.
