圧切換形変圧器の保護回路。A transformer in which the input winding is divided into two, each end of the winding is connected to a terminal, and the two windings are connected in series or parallel by shorting with a shorting bar between the specified terminals to correspond to the magnitude of the input voltage. In this case, the excitation coil of the relay is connected between the two terminals that are shorted when connected in series so that it operates at the higher rated input voltage, and the normally closed contact of the relay is inserted between the two terminals and the winding end. A protection circuit for an input voltage switching transformer.
