arrangement for switching the übersetzungsverhältnisses a transformer, in particular to a mittelfrequenztransformators to generate the voltage of x-ray tube

摘要

In the case of the method for changing the transformation ratio of a transformer (1) on the primary side, the transformer (1) together with the load (2) connected on the secondary side is automatically isolated from the power supply before operation of the stepping switch (4) for selective connection of sections of the primary winding (3) via a load switch (9) on the primary side, the changeover is carried out, and the power is connected again. Used in the case of transformers having a large voltage and current range, especially for supplying X-ray tubes. IMAGE
