Abstract

PURPOSE: To prevent definitely a large-capacity transformer from racing by making automatically the transformer, when applied with no load, free from a power supply.
CONSTITUTION: At the primary side of large-capacity transformer 1, meter relays XC1 and XC2 are provided which detect a load current and after fixed time passes since they detect no load current flowing through transformer 1, the power supply of the primary side of transformer 1 is automatically disconnected by contact SW0 of a high-tension vacuum breaker. When the power supply is put to work again, either near switch SW1 or SW2 switching respective loads connected to the secondary side of transformer 1 is turned on to make automatically contact SW0 of the high-tension vacuum breaker in consequence, so that power will be supplied. Therefore, the trouble of turning ON-OFF the transformer can be eliminated.
