劣化を防止していた。In this structure, corona is likely to occur between the outer end surface of the insulating case 2 and the magnetic core 3, so the adhesive 1 is used to regulate the gap between the insulating case 2 and the magnetic core 3 in the coil part and adhere them to prevent the occurrence of corona. This prevents deterioration of the insulating case 2 due to the occurrence of corona.

止も確実なものになる。The a dimension of the magnetic core 7 is regulated to the relationship a>b for the 6 dimensions of the magnetic core insertion hole 6, the magnetic core 7 has a gap in the C direction, and the distance d between the insulating case 4 of the coil part and the magnetic core 7 is the rib dimension. By regulating the dimension e of the rib 6, it is possible to ensure a distance to prevent the occurrence of corona.Therefore, there is no need to glue the insulating case 4 of the coil and the magnetic core 7, allowing for easy and reliable fixing. This also reduces costs. In addition, the area of the surface f where the insulating case 4 and the magnetic core 7 of the coil part contact each other at the fitting part increases, and leakage of the insulating material cast into the coil part can be reliably prevented.
