Electricity transmission device for vacuum chamber has transformer with fixed part connected to rotatable tubular cathode

摘要

Electricity transmission device for vacuum chamber from a power supply outside a vacuum chamber (2) to at least one tubular cathode (7, 8) inside the vacuum chamber. It includes a transformer, which has a fixed part (36) connected to the tubular cathode, which can be rotated. Conducting lines (40, 41) run from the rotatable part (35) of the transformer to one of the tubular cathodes (8).
