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.

A protection system (10) is proposed which comprises a storage container (1), a transport unit (2), an activation unit (3), an ejection unit (4), a monitoring/control unit (5) and a user unit/interface (6), as well as at least one effect body (7). This system (10) is integrated at the front in a flying carrier (11), and a modular system (10), with the object of positioning spoof measures in a defined manner, in this case by means of the effect body (7). The various effect bodies (7) are preferably activated and initiated in a controlled manner without any physical contact, in the same way as pneumatic or mechanical ejection of these effect bodies (7). The effect bodies (7) are packets without any munitions, and are responsible for the actual effect of the system (10) outside the carrier (11).

A drive configuration includes a common drive device and driver elements. The driver elements interact with drive elements in order to transmit a drive movement generated by the drive device to movable contact pieces of switching poles or switchgears of an electric switching device. At least one of the switching poles or switchgears has a first driver element and a second driver element, in which the first driver element serves for the generation of a switching-on movement, and the second driver element serves for the generation of a switching-off movement.

摘要:
A method determines a switching time of an electric switching device containing an interrupter path disposed between a first line section subjected to a driving voltage and a second line section that forms an oscillating circuit after the switching device undergoes a shut-off step. The method is used for determining the best possible switching time for an electrical switching device to minimize transient voltage surges. It is proposed that either—a temporal progression of a voltage that develops along the interrupter path is determined during a scanning period; or that—a temporal progression of a voltage that develops along the interrupter path is determined during the scanning time.
摘要:
An electrical switching device with potential control has at least one interrupter unit. The interrupter unit has an electrical switching point and an electrical capacitance with respect to the electrical grounding. Conventionally, electrical switching devices, such as circuit breakers for high-voltage installations, for example, with so-called control capacitors, which are connected in parallel with the switching point, are used for making the voltage uniform across a plurality of interrupter units of an electrical switching device. As a result, a virtually uniform voltage load on all the interrupter units of the electrical switching device is ensured. The idea here is to use resistive and/or inductive components for making the voltage uniform across the electrical switching device instead of or in addition to the control capacitors used.
