Abstract

Elektrisk strømforsyningssystem for traksjon innbefattende i det minste en transformator, for eksempel en autotransformator eller en strømforsterkertransformator og/eller en roterende omformer. Transformatoren eller den roterende omformeren innbefatter en vikling med isolasjon bestående av minst to halvledende lag (32, 34), hvor hvert lag danner en overflate med i det vesentlige likt potensial og massiv isolasjon (33) mellom de halvledende lagene.Electrical power supply system for traction including at least one transformer, for example an autotransformer or a current amplifier transformer and / or a rotary converter. The transformer or rotary converter comprises a winding with insulation consisting of at least two semiconductor layers (32, 34), each layer forming a surface with substantially equal potential and solid insulation (33) between the semiconductor layers.
