In allusion to the situation concerning incomplete safeguard measures for secondary side power outage overhauls of voltage transformers,as well as the shortage of standardized and systematic approaches,a type of secondary air switch locking and grounding protection system for voltage transformers is developed,which solves the problem that the secondary air switch is unavailable for closed grounding and eliminate the risk of secondary reverse power transmission.
