Transformer for power supply installations

摘要

There is at least one primary coil (11) on the primary side and at least one secondary coil (12) on the secondary side, as well as at least one screen (17-19) for the primary and secondary coils. Of the three screens, at least, the first one (17) is associated with the primary coil and coupled to the potential (P) of the primary side. The second screen (18) is coupled to the central reference potential (PE) of the transformer (10), and the third screen is coupled to the reference potential of the secondary side. Pref. the screens are arranged in overlapping layers.
