TRANSFER SWITCHING SYSTEM FOR REGULATING TRANSFORMERS INCLUDING THYRISTOR NETWORK AND LOGIC CONTROLS THEREFOR

摘要

A system for performing tap-changing operations on tapped regulating transformers by thyristor networks and disconnect contact means. The trigger pulse generators for the thyristors of the networks are controlled by sensors whose output is fed into a logic circuitry. The latter includes a bistable device and a pair of AND-gates.
