Title:
CHANGEOVER CONTROL DEVICE AND CHANGEOVER CONTROL METHOD
Document Type and Number:
Japanese Patent JP2017143636
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a changeover control device capable of reliably suppressing a temperature rise while maintaining a voltage regulation function that is required for a voltage regulation apparatus, at a maximum and a changeover control method.SOLUTION: A changeover control device 10 configured to control changeover of a tap in a voltage regulation apparatus 100 comprises: a control signal generation unit 11; a temperature input unit 12 for acquiring a circuit temperature measured by circuit temperature measurement means which is provided within the voltage regulation apparatus 100 and measures the circuit temperature; and a changeover interval adjustment unit 13 for variably limiting a changeover interval that is an interval of changeover of the tap, in accordance with the circuit temperature which is acquired by the temperature input unit 12. Specifically, the changeover interval adjustment unit 13 limits the changeover interval step by step, sets a limit time for limiting the interval of changeover of the tap in accordance with the circuit temperature, and limits the changeover interval on the set limit time basis.SELECTED DRAWING: Figure 2
