Latest Patents

Kinoshita's latest patents include an inrush current suppressing device that features a residual-magnetic-flux calculating unit. This unit retains the interruption characteristic of a breaker and the attenuation characteristic of a magnetic flux, which are estimated through measurement and analysis. The device calculates a residual magnetic flux value by applying the attenuation characteristic to a magnetic flux value at the time of current interruption. This innovation allows the breaker to be turned on in a power supply voltage phase where the calculated residual magnetic flux value aligns with a theoretical steady magnetic flux value. Another notable patent is an inrush-current suppressing device and method that calculates a residual magnetic flux in a reference phase of a three-phase transformer. This device operates based on a measurement result from a transformer-voltage measuring unit and actuates a switch of the three-phase circuit breaker at the optimal timing.
