| Zusammenfassung: | A stationary induction apparatus includes a core, a first winding, a second winding, and an insulating structure arranged between facing surfaces of the first winding and the second winding. The insulating structure is located between the facing surfaces of the first winding and the second winding. The insulating structure includes a first insulator having a cylindrical shape with the core as its central axis, and first insulating spacers arranged between the first winding and the first insulator and between the second winding and the first insulator. The first insulator includes a first nonlinear resistive layer containing a nonlinear resistive material having a nonlinear volume resistivity that decreases when an electric field is higher than a threshold. The first nonlinear resistive layer is provided in a portion of the first insulator which is at least in contact with one of the first insulating spacers. |
