Abstract

PURPOSE:To introduce a refrigerant liquid efficiently to a tongue-section core, to prevent the partial temperature rise of the core and to reduce the usage of the refrigerant liquid by installing a damming angle, to which a notch is formed, onto the underside of an upper structure in which the refrigerant liquid is flowed down. CONSTITUTION:In a stationary induction apparatus in which a cooling medium 10 composed of an insulating liquid is passed in an upper structure and flowed down on the side face of a core 2 in a coil group 1, a damming angle 9 to which notches 9a are shaped is mounted onto the underside of said upper structure. In a shell-type evaporative cooling type gas insulation transformer, the damming angle 9 with the notches 9a is set up onto the top face of an electromagnetic shield 4b. Accordingly, the refrigerant liquid 10 flowed down from the upper section of a tank 3 is flowed in a clearance 5a among the wedges of upper wedges 5, collected in a total-weight shielded pan 7 by the damming angle 9 when it is dropped onto the top face of the electromagnetic shield 4b, and introduced to the tongue section of the core 2 through a clearance in the shield and flowed down on the side face of the core.

[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.

[Embodiment] An embodiment of the present invention will be described below with reference to FIGS. 1 and 2. There is a notch (9) on the top of the electromagnetic shield <4b>
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.
