摘要： A power conditioning, distribution and management system includes a switch circuit that enables coupling of an AC power supply to a load though an overcurrent device. A control circuit switches the switch circuit from a non-conductive state to a conductive state when a supply voltage signal is between first overvoltage and undervoltage thresholds. The control circuit records an overvoltage event and maintains the switch circuit in the conductive state when the supply voltage signal exceeds a second, higher overvoltage threshold and switches the switch circuit to a nonconductive state when the supply voltage signal exceeds a third, highest overvoltage threshold. The control circuit records an undervoltage event and maintains the switch circuit in the conductive state when the supply voltage signal falls below a second, lower under-voltage threshold and switches the switch circuit to the non-conductive state when the supply voltage signal falls below a third, lowest undervoltage threshold.

摘要： Apparatus and methods provide for the application of a mechanical impulse to the switch at a phase angle before a zero crossing of the current to disconnect a switching contact and mating contact to control electric arcing. According to one aspect, a next zero crossing of an alternating current is detected, and in response, a mechanical impulse with a phase angle of between 5° and 20° is applied before the next zero crossing of the alternating current. The mechanical impulse disconnects the switching contact from the mating contact of the switch.

摘要： A switching circuit, e.g. an RCD, comprises a pair of mechanical contacts (M) in an alternating current electricity supply (N, L) and circuit means (SCR) for opening the contacts to cut off the supply in response to a switching signal (S). The switching circuit includes further circuit means (Rs, Cs, D2, D3, Q1, Q2) for defining successive periods of time (“activation windows”) during which the magnitude of the supply voltage is not at a maximum and allowing the contacts to open in response to a switching signal only during such windows.

摘要： A residual-magnetic-flux calculating unit includes a voltage-change-rate detecting unit that detects a transformer-voltage change rate from a phase voltage between a breaker and a transformer, a residual-magnetic-flux detecting unit that detects a residual magnetic flux remaining on the transformer based on the phase voltage, and a breaker-switching-state identifying unit that detects a switching state of the breaker. 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 device for operating a relay to selectively provide power from a power supply to a load. The device determines an activation switching point for activating the relay such that inrush current resulting from the activation is minimal. The device also determines a deactivation switching point for deactivating the relay such that backrush current is minimal. The switching points are determined with respect to a voltage waveform of the supply power. The device varies the timing of the operation of the relay with respect to the voltage waveform and monitors the inrush or backrush current resulting from each timing until a minimum inrush or backrush current is found. The device stores these times in memory for subsequent operation of the relay. To further reduce inrush and backrush currents associated with inductive loads, the device activates and deactivate the relay on opposite half cycles.

摘要： A hybrid switch circuit includes a hybrid switch that couples an input conductor connected to an AC power supply to an output conductor connected to a load. The hybrid switch includes a power semiconductor in parallel with an electromagnetic relay. A control circuit turns on the hybrid switch by turning on the power semiconductor at a zero-voltage crossing of the AC voltage to provide a conductive path and then closing the relay to provide a conductive bypass path that bypasses the power semiconductor. The control circuit turns off the hybrid switch by opening the relay and subsequently turning off the power semiconductor at a zero crossing of the load current. The control circuit operates in response to at least one switch control signal that indicates whether an operating fault condition exists.

摘要： A switching controlgear of circuit breaker 100 outputs an opening command signal or closing command signal to the circuit breaker with the maximum being 1 cycle or less of wait time when the opening command signal or closing command signal is detected, and can cause the circuit breaker to open or to close at a desired phase of the main circuit current or power system voltage. The switching controlgear of circuit breaker 100 has switching control signal output time calculation means 10 and switching command signal output delay means 20. The switching control signal output time calculation means 10 calculates the switching control signal output time using the detection timing of the opening command signal or closing command signal as a reference so that the circuit breaker opens or closes at the desired phase after the total time of the switching control signal output time and the estimated opening operation time or estimated closing operation time of the circuit breaker 620 is elapsed. The switching command signal output delay means 20 outputs a delay-controlled opening command signal or a delay-controlled closing command signal to the circuit breaker after the switching control signal output time, which is the latest, is elapsed when an opening command signal or closing command signal is actually detected.

摘要： A method and a device for determining a switching time of an electric switching device. An electric switching device includes an interrupter link. A first line section and a second line section can be connected and disconnected by way of the interrupter link. In order to determine a switching time, the temporal progression of a driving voltage is determined in the first line section. In addition, a temporal course of an oscillator voltage appearing in the second line section is determined. Potential switching times are determined at the voltage zero crossings of a resulting voltage. The selection of the potential switching times ensues while evaluating the rises of the driving voltage and of the oscillator voltage or of the polarity of the oscillating current.
