The residual-magnetic-flux calculating unit recalculates the residual magnetic flux based on the transformer-voltage change rate and a predetermined threshold while the breaker is in an open state.

摘要： A switchgear control apparatus includes a zero point interval detecting circuit, an interruption time judgment circuit and a reclosing time decision circuit. The zero point interval detecting circuit detects time intervals between successive zero points of a main circuit current. The interruption time judgment circuit judges that interruption time of the main circuit current is time of a zero point immediately preceding a zero point at which a difference between the time interval between two successive zero points and half the period of a commercial AC voltage exceeds a specific value. Upon detecting the gradient of the main circuit current at the interruption time, the reclosing time decision circuit sets reclosing time at a point in phase where the AC voltage has a maximum negative value if the gradient is positive, and at a point in phase where the AC voltage has a maximum positive value if the gradient is negative.

摘要： A power switching apparatus includes a breaker unit, an operating unit, a measuring unit, and a controlling unit. The breaker unit is connected on a three-phase current line, and includes switches each corresponding to one of phases of the three-phase current line. The operating unit simultaneously turns on or off the switches. The measuring unit measures a current flowing in each phase, and determines a time point where current flowing in one of the phases becomes zero as a reference time point. The controlling unit controls, when interrupting load current, the operating unit to turn off the switches in a range from 20 degrees to 40 degrees of an electric angle from the reference time point.
