Abstract

(57) Система электроснабжения для тяги содержит, по меньшей мере, один трансформатор, например автотрансформатор или вольтодобавочный трансформатор тока, и/или вращающийся преобразователь, при этом трансформатор или вращающийся преобразователь содержит изоляцию, состоящую, по меньшей мере, из двух полупроводящих слоев 32, 34, каждый из которых обеспечивает по существу эквипотенциальную поверхность, и из твердой изоляции 33 между полупроводящими слоями.Международная заявка была опубликована вместе с отчетом о международном поиске.(57) The power supply system for thrust contains at least one transformer, for example an autotransformer or booster current transformer, and / or a rotating converter, while the transformer or rotating converter contains insulation consisting of at least two semiconducting layers 32, 34, each of which provides a substantially equipotential surface, and solid insulation 33 between semiconducting layers. The international application was published along with an international search report.
