HIGH- OR MEDIUM-VOLTAGE DEVICE COMPRISING A PARTICULAR DIELECTRIC SYSTEM

摘要

The invention concerns a high- or medium-voltage device comprising an electrically conductive part (3) and a dielectric system, characterized in that said dielectric system includes: a) a solid semiconductor layer (7) deposited on said conductive part; b) a solid layer having a non-linear electrical conductivity based on the electric field (9) deposited on the solid semiconductor layer (7); c) a solid electrically insulating layer (11) deposited on the layer (9). The invention is applicable to power supply transformers, measurement transformers, circuit breakers, busbars.
