Abstract

PURPOSE: To automatically prevent the transverse movement of transformer during parallel operation by calculating the secondary voltage at the position of intermediate terminal and then making the automatic operation of each intermediate terminal so as to make the secondary voltages of each transformer coincide by using the calculated values.
CONSTITUTION: When the operation device 17 makes the stop operation of the transformer 4a, the transformers 4a and 4b are in parallel operation during a series of operation involving the making of the bus connection breaker 9, the closing of the secondary breaker 7a, and the closing of the primary breaker 6a. In order to prevent tripping, the voltages of the buses 8a and 8b for the case in which the transformers 4a and 4b are assumed to be burdened with no load are compared, and then the values are made coincide by making an automatic rise and fall operation for any of the terminals of the intermediate terminal switching units 5a and 5b.
