構成する。2. Description of the Related Art In general, a molded transformer is often used by being housed in a switchboard. Therefore, except for those requiring special seismic strength, a vibration isolating rubber is disposed between the transformer and a base. Is common. Conventionally, a molded transformer provided with a vibration isolating rubber has a 2000K as illustrated in FIGS.
There is a mold transformer of about VA. In this method, an anti-vibration rubber 2 is placed on a transformer base 1 and an iron core 3 is placed thereon.
On the iron core base 3, an iron core unit which is obtained by bundling the iron core 4 with an iron core clamp 5 disposed at the end thereof and integrating the core is installed. Iron core 3
Is made of box-shaped steel. Further, a bolt 6 is passed through a through hole penetrating from the transformer base 1 to the vibration isolating rubber 2, the iron core base 3 and the iron core clamp 5, and a nut 8 is fitted through a vibration isolating material 7. , To fix the iron core.

In this way, it is possible to prevent the vibration of the molded transformer from being transmitted to the thin iron plate material constituting the outer part of the switchboard accommodating the molded transformer, thereby increasing the noise value. Further, in the conventional mold transformer, the temperature of the iron core 4 rises during use, but the heat is radiated to the surrounding air at the iron core base 3 which is a hollow member so as not to be transmitted to the vibration isolating rubber 2. I have. By doing so, the vibration isolating rubber 2 is prevented from being heated and deteriorated.

れていながらもそれができないという問題があった。In the above-described conventional mold transformer, a vibration isolating rubber must be arranged for noise prevention, and the height dimension is large to prevent the thermal vibration of the vibration isolating rubber. Since the iron core table must be arranged, the height of the molded transformer is increased by that much, which has been a great hindrance to downsizing the molded transformer. In addition, when installing this in a switchboard, a large installation space is required, and there has been a problem that miniaturization of a molded transformer has been strongly desired but it has not been possible.

きるものである。With the construction described above, vibrations generated in the iron core are absorbed by the vibration isolating rubber to prevent the noise from expanding, and the heat generated in the iron core is insulated by the heat insulating material and is not transmitted to the vibration isolating rubber. In this way, the vibration isolating rubber is prevented from being deteriorated by being heated. Furthermore, since the conventional high iron core base formed in a box shape is replaced with a flat iron core base and a heat insulating material, the height can be reduced, and the molded transformer can be reduced in size accordingly.

Insulation material is placed on the anti-vibration rubber, and an iron core base is placed on the heat insulation material.The vibration generated by the iron core is absorbed by the anti-vibration rubber to prevent the noise from expanding, There is an effect that the heat generated in step (1) is insulated by a heat insulating material so that the heat is not transmitted to the prevention rubber, and deterioration due to the heating of the vibration prevention rubber can be prevented. Further, since the conventional high iron core base formed in a box shape is replaced with a flat iron core base and a heat insulating material, the height can be reduced, and the molded transformer can be reduced in size accordingly. Moreover, since the height can be reduced without changing the configuration of the transformer main body, there is an effect that the reliability of the performance of the transformer can be maintained. Further, since the heat insulating material is used, it is possible to set the place where the vibration isolating rubber is disposed immediately below the iron core, and it is possible to easily design the main body of the molded transformer. Further, when the miniaturized mold transformer is installed in the switchboard, there is an effect that a limited space in the switchboard can be provided with a space that can be effectively used.
