摘要： Respective contact terminals in respective arc-suppressing spaces of respective breakers are opened at a voltage zero point of any phase of three phases, simultaneously among the three phases. If current breaking is carried out for the three phases at the same time, when the breakers of the three phases are opened, the residual magnetic levels of the respective phases of a transformer can be controlled so that the residual magnetic flux level of the phase opened at the voltage zero point is maximum (for example, −2 K or +2 K) and the residual magnetic flux level of the other two phases are opposite in polarity to the residual magnetic flux level of the phase concerned and equal to substantially the same residual magnetic flux (for example, +K and +K or −K and −K) which is equal to about one half of the residual magnetic flux level of the phase concerned. Accordingly, by throwing the phase broken at the voltage zero point at a first time, the difference in residual magnetic flux between the second throwing phase and the third throwing phase just after the first phase is thrown can be substantially nullified.

摘要： A control portion 80 for a breaker 10 causes the breaker 10 to apply a current of a first apply phase (R phase) at a timing where a residual flux of R phase agrees with a steady magnetic flux. Thereafter, the control portion 80 determines whether or not the current measured by current measuring portions 40R, 40S, 40T exceeds a threshold value. When the measured current does not exceed the threshold value, the control portion 80 causes the breaker 10 to apply currents of the other two phases (S and T phases) at a timing where a voltage of R phase becomes zero. When the measured current exceeds the threshold value, the control portion 80 causes the breaker 10 to once shut off the current of R phase and to apply again the current of R phase.

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： An edge exposing apparatus includes a photo detector and a lighting time measuring circuit for detecting a decrease in performance of light source units. The lighting time measuring circuit detects a ready state ((stabilization of luminous intensity) of the light source units, for example by measuring a lighting time for a startup (switch-on) of the light source units. When the measuring circuit detects a preset lighting time, or when the photo detector detects a luminous intensity below a preset value, the light source units are determined to have lowered performance, and are switched off. When a decrease in performance of one unit is detected, a replacement light source unit is started while continuing edge exposure with one or more other light source unit(s). When a ready state is detected, the edge exposure with the one light source unit is terminated (switch-off), and edge exposure is performed with the replacement light source unit.
