Abstract

The on-load tap changer is intended for multi-stage transformers. The tap changer has two load branches, each with a pair of anti-parallel thyristors and a mechanically actuated relief contacts for the thyristors pairs. In order to monitor the switching time of the relief contacts (11-14) each load branch has an associated relay (18, 19). The relay is actuated by the voltage applied to the thyristor pair (5, 6) of the respective load branch. Across the contacts (20, 21) of the two relays is connected a safety circuit (22), incorporating a relay with adjustable time delay. The design helps to detect interference in the mechanical switching.
