TRANSFORMER FOR RECTIFIER

摘要

PROBLEM TO BE SOLVED: To reduce temperature rise of a low voltage winding in the cooling structure of winding where the width of an outside cooling medium passage of the low voltage winding is different from the width of an inside cooling medium passage in a transformer for rectifier.

SOLUTION: In the transformer for rectifier where the low voltage winding is arranged between a core and a high voltage winding, cooling medium passages having different passage widths are provided on the inside and outside of the low voltage winding in order to cool the low voltage winding. The inside and outside cooling medium passages are arranged between insulation tubes where interval adjustment members are arranged to include the low voltage winding and the core so that the widths of the inside and outside cooling medium passages having different widths are substantially equalized.
