摘要： Examples relate to power supply system comprising a primary power supply to deliver a first power to a load and a secondary power supply that, in response to a failure in the primary power supply, is to deliver a second power to the load. The system further comprises a primary energy storage component coupled to the primary power supply that, in response to the failure in the primary power supply, is to deliver a third power to the load while the secondary power supply transitions from a lesser output power level to a greater output power level. The third power is at the same full-rated power level than the first power.

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 supply circuit interrupts power to a load in response to a short-circuit or an open-circuit condition and automatically restores power after a momentary short-circuit. A short-circuit detector monitors the current flowing through the load and generates a short-circuit signal if the current exceeds a predetermined level. An open-circuit detector monitors the load voltage and generates an open-circuit signal if the voltage exceeds a predetermined level. A latch converts the short-circuit signal to a latch signal. A logic unit combines the latch signal with the open-circuit signal and a pulse signal from a pulse generator to generate a drive signal. A driver uses the drive signal to control a switch which is connected between the power source and the load to interrupt power to the load. During a short-circuit, a timer generates a periodic pulse signal that toggles the latch signal and intermittently restarts the power to the load. If the short-circuit was of short duration, power is restored to the load. If the short-circuit persists, the power supply circuit continues to intermittently restore power to the load until the short-circuit is removed. The logic unit also generates a fault signal in response to the latch signal and the open-circuit signal. A display unit generates a visual alarm in response to the fault signal to indicate an abnormal state.
