PURPOSE: An energy-saving type high and low voltage switchgear operation control method minimizes operating loss by analyzing the state of integrated operation. CONSTITUTION: Two transformers (24,25) are accommodated in switchgear. A power receiving part (100) and multiple power distribution parts (200,300,400) are arranged on the transformer. Data information during an off-peak power consumption period is obtained. The capacity of each transformer is compared. A phase voltage between the two transformers is detected by using a voltage transformer. [Reference numerals] (24) Transformer A; (25) Transformer B; (32) Load 1; (33) Load 2 |
