しかしながら、直線沿面においては、ストリーマが比較
的°容易に進展し、沿面破壊に至る。そのため単に直線
沿面距離で絶縁を保つには、直線距離を長くし、従って
変圧器の鉄心脚長さや重量音大きくする必伊があった。However, on straight creeping surfaces, streamers develop relatively easily, leading to creepage failure. Therefore, in order to simply maintain insulation with a linear creepage distance, it was necessary to increase the linear distance, and thus increase the length of the transformer's core legs, weight, and noise.

供しようとするものである。The present invention obviates the above drawbacks. -K □-= Voltage transformer, that is, the linear creepage distance does not vary greatly, so the length and weight of the core legs do not increase, and the pleated insulation and U-shaped press pod prevent the streamer from progressing. Therefore, the present invention aims to provide a compact high voltage transformer with a long effective creepage distance.

のである。In the uninvented 1% voltage power supply voltage converter shown in FIG. 4, a groove is further provided in the creeping part of the insulating molded material, and a plenu board 9 is bent into a U-shape in this groove. By inserting io, n, 12, 13, and 14 and surrounding the pressure area, the withstand voltage is improved. In an attempt to create a vortex as shown in Figure 4, the experimental value was DC800.
kV,, 1ml is maintained for 10 minutes, and when compared with the linear creeping case shown in Figure 1, the withstand 'tlr pressure is improved by more than 300kV DC, although the core and winding dimensions are the same. obtained, and is of great industrial and practical value.
