It is necessary to provide a predetermined insulation distance L 1 so as not to occur. Then, in order to secure the insulation distance L 1 , a spacer 20 is arranged between the lead wires a and b, and the lead wires a and b are brought into contact with both ends of the spacer 20 to fix the lead wire fixing member 21. The lead wires a and b are supported and fixed to the lead wire support column 17 by applying the insulating bolts 22.

To be

表１のようにＬ1寸法に比べＬ2寸法が大きくなる。For example, when press paper is used for the spacer, the difference in dielectric constant between the spacer and the insulating medium causes
As shown in Table 1, the L 2 dimension is larger than the L 1 dimension.

に大きくなり、それに伴ってタンクも大形となる。This means that, when the insulation distance L 2 is determined by the dielectric constant of the spacer, L 1 is about 2 times for insulating oil and about 4 times for insulating gas. Therefore, when a large number of lead wires are led out, the area occupied by the lead wire support device becomes very large, and the tank becomes large accordingly.

のである。Means for Solving the Problems In the present invention, a means for solving the above problems is to wind a winding around an iron core and fix a plurality of lead wires from the winding to a lead wire support column. In a lead wire supporting device for a transformer, which comprises a content main body, and the content main body is housed in a tank together with an insulating medium, a plurality of lead wires supported by the lead wire supporting columns are
The insulation distance is determined by the potential difference between the lead wires adjacent to each other and the dielectric constant of the insulating medium, and the lead wire fixing member for fixing the lead wire to the lead wire support column has an interval corresponding to this insulation distance. A plurality of grooves are provided, and lead wires are fitted into these grooves and attached to the lead wire support column.

なる。With such a very simple structure, the required insulation distance can be secured without the spacer, and moreover,
Since there is no spacer, the insulation distance between adjacent lead wires can be determined by the dielectric constant of the insulating medium. Therefore,
The distance between the lead wires can be reduced by about 1/2 when the insulating medium is insulating oil, and by about 1/4 when the insulating medium is insulating gas.
