Title: STATIC INDUCTION ELECTRICAL DEVICE
Abstract:
A static induction electrical device according to this embodiment has an iron core, windings, a container, and a spacer unit. The iron core has a leg section and a pair of yoke sections. The leg section extends along a first direction. The pair of yoke sections extend from both ends of the leg section along a second direction intersecting the first direction. The windings are wound on the leg section and are tightened by the pair of yoke sections in the first direction. The container accommodates the iron core and the windings. The spacer unit has a plurality of spacers. The plurality of spacers are sandwiched between windings neighboring in the first direction. The plurality of spacers are arranged in a lined-up manner in a circumferential direction about winding axes of the windings. In the spacer unit, the amount of strain in response to a force in the first direction differs depending on the position in the circumferential direction.
