INRUSH CURRENT SUPPRESSING DEVICE |
摘要 |
An inrush current suppressing device includes a residual-magnetic-flux calculating unit configured to retain an interruption characteristic of a breaker and an attenuation characteristic of a magnetic flux that are estimated by measurement, analysis, or the like beforehand, and apply the attenuation characteristic to a magnetic flux value at the time of current interruption obtained based on the interruption characteristic of the breaker to calculate a residual magnetic flux value. The breaker is turned on in a power supply voltage phase in which the calculated residual magnetic flux value and a theoretical value of a steady magnetic flux match.
