【考案の詳細な説明】 〔産業上の利用分野〕 この考案は電磁誘導機器に関し、特に磁気シールドを
備えた電磁誘導機器の小形化に関するものである。DETAILED DESCRIPTION OF THE INVENTION [Industrial application] The present invention relates to an electromagnetic induction device, and more particularly to miniaturization of an electromagnetic induction device provided with a magnetic shield.

下に磁気シールド（４）を配置している。In the figure, (1) is a winding composed of a high-voltage coil wound around the iron core (3), and (2) is a winding composed of a low-voltage coil. (4) is an integrated magnetic shield arranged under the windings (1), (2), and is fixed on the lower end frame (5) of the iron core. (6) shows a cooling flow guide, (7) shows a tank, and arrow A shows a flow of a refrigerant such as insulating oil for cooling the electromagnetic induction device. The cooling flow A passes through the cooling inflow port (8) and is arranged along the high pressure coil (1) and the low pressure coil (2) as oil passages (9a), (9b), (9c), as refrigerant passages.
It is guided to (9d) to cool the high and low voltage coils. Generally, when the electromagnetic induction device has a large capacity, the amount of leakage magnetic flux increases, and in order to reduce stray loss due to it, magnetic shields (4) are arranged above and below the winding as shown in FIG.

う問題点があった。Since the conventional electromagnetic induction device is configured as described above, the cooling flow tends to flow to the coil arranged on the outer side, while the cooling flow flows to the coil wound on the inner side only slightly. .. Considering this small amount of cooling flow, the temperature rise value of the inner coil is designed to be below the specified value.
There has been a problem that the loss generated in the inner coil has to be reduced as much as possible so as to correspond to the cooling flow, and as a result, the size of the inner coil becomes large and the electromagnetic induction device itself also becomes large.

容易になる。[Operation] In the electromagnetic induction device of the present invention, since the plurality of passages through which the refrigerant flows are formed immediately below the refrigerant passage, the refrigerant smoothly flows through each refrigerant passage, and the winding is efficiently cooled. Further, since the magnetic shield is divided, the divided magnetic shield can be reduced in size and weight, and the magnetic shield can be easily handled during the assembly work of the electromagnetic induction device.

The passage portions (4a) to (4) corresponding to the refrigerant passages (9a) to (9d)

d) is provided and forms a plurality of inlets (8), (8) .... The other reference numerals are the same as those in the above-mentioned conventional device, and thus the description thereof is omitted.

達成できる。Next, the operation will be described. The cooling flow indicated by the arrow A has a plurality of inflow ports (8), (8) ...
Passages (4a), (4b), (4c) formed by
After passing through (4d), the refrigerant flows almost evenly through the refrigerant passages (9a) to (9d) provided between the coil windings (1) and (2). Therefore, the coil (2) close to the iron core (3) is cooled substantially equally as the outer coil (1). Therefore, according to this embodiment, a cooling flow commensurate with the generated loss of the low-voltage coil (2), which is the winding arranged inside, can be obtained, so that the coil design corresponding to the cooling flow can be performed, which is the same as the conventional case. Since the coil itself can be designed smaller than the coil in which the cooling flow does not easily flow, the electromagnetic induction device such as a transformer can be made smaller and lighter.

For example, it may be appropriately changed according to the loss generated in the windings (1) and (2), the number of refrigerant passages (9), and the like. Further, although only the structure of the lower part of the device is shown, it is natural that the same structure can be applied to the upper part.

なるという効果もある。As described above, according to the present invention, since the plurality of passages through which the refrigerant flows are formed immediately below the refrigerant passages, the refrigerant smoothly flows through each refrigerant passage, the winding is efficiently cooled, and the cooling flow is reduced. It is possible to design a coil suitable for the above, and it is possible to obtain an electromagnetic induction device in which the coil itself is made small and the size and weight are reduced. Further, since the magnetic shield is divided, the divided magnetic shield can be reduced in size and weight, and the magnetic shield can be easily handled during the assembly work of the electromagnetic induction device.
