    摘要: A DC current path (4) for DC power transmission comprises a switchable element (1). An inductance (2) is connected in series to the switchable element (1). When an interrupt scenario is detected, a resonance circuit (3) is connected in parallel to the series connection of the switchable element (1) and the inductance (2) for charging a capacitance (32) of the resonance circuit (3). An open state of the switchable element (1) is effected and the resonance circuit (3) is connected in parallel to the switchable element (1). By means of such arrangement and method, very favourable fast interrupt times can be achieved.

    摘要: In one aspect, an apparatus, such as an electrical system (100), is provided. The electrical system can include a pair of conductors (110) across which an arc (122) is sporadically supported, the arc including load current from a load circuit (114). The electrical system can also include an energy source (128) that is separate from the load circuit and configured to selectively charge an electrode assembly (126). The conductors and electrode assembly can be configured such that the arc, when present, will be lengthened or constricted due to the charge on the electrode assembly.

    摘要: In one aspect, the present invention provides an electromagnetic circuit interrupter 100 for use in a high voltage direct current (DC) aircraft power distribution system. The electromagnetic circuit interrupter 100 comprises a contact mechanism 102 operable to separate first and second electrical contacts 120, 130 by a first predetermined distance d 1 for a predetermined time τ so as to sustain an arc 150 when the contact mechanism 102 is opened. The contact mechanism 102 is further operable to separate the first and second electrical contacts 120, 130 by a second predetermined distance d 2 after the predetermined time τ so as to extinguish the arc 150. The first predetermined distance d 1 is less than said second predetermined distance d 2 . By deliberately sustaining the arc 150 for a relatively long period of time, this aspect of the present invention is particularly useful for extending the operational lifetime of the contacts 120, 130 and thereby of the electromagnetic circuit interrupter 100 itself.

    摘要: The invention relates to an electric direct current network (1) for surface and submarine vessels and for offshore units, having at least one direct current source (2), in particular a battery and/or fuel cell installation, at least one electric consumer (3), e.g. an electric drive motor or a border network, and at least one shut-off device (4) for shutting off a direct current flowing into the direct current network (1). The shut-off device (4) comprises a vacuum switch (5) that is switched in the network and a commutation device (8 or 9), through which a produced electric arc can be turned off when the switch (5) is opened. The shut-off security can be increased such that the vacuum switch (5) comprises a first switch pole (5a) and a second switch pole (5b). The first switch pole (5a) is switched in a current branch (6) from a plus pole of the direct current source (2) to the consumer (3) and the second switch pole (5b) is switched in a current branch (7) from a minus pole of the direct current source (2) to the consumer (3). Both of the switch poles (5a, 5b) are mechanically coupled together and the shut-off device (4) for at least one of the two switch poles (5a, 5b) comprises a commutation device (8 or 9) for turning off an electric arc produced in said switch pole (5a or 5b).

    摘要: Eine Lasttrenner-Anordnung (1) zum Zu- und Abschalten eines DC-Stromes eines DC-Stromkreises in einer Photovoltaikanlage mit einem Halbleiter-Schaltelement (4) zur Vermeidung eines Schaltlichtbogens, soll derart verbessert werden, dass einerseits ein DC-Strom in einer Photovoltaikanlage sicher abzuschalten ist, und zwar nicht nur manuell sondern auch automatisch, und andererseits eine galvanische Trennung in mindestens einer der zwei stromführenden Leitungen des DC-Stromkreises erzielt wird. Dies wird dadurch erreicht, dass eine elektronische Steuereinheit (5) vorhanden ist, die derart ausgeführt ist, dass ein oder mehrere Steuersignale an die Lasttrenner-Anordnung (1) weitergegeben werden, dass ein Zu- oder Abschalten des DC-Stromkreises durch die Steuersignale automatisch bei mindestens einem bestimmten Ereignis, insbesondere bei einem Fehlerfall, erfolgt und dass die Lasttrenner-Anordnung (1) so ausgeführt ist, dass in mindestens einer stromführenden Leitung des DC-Stromkreises im abgeschalteten Zustand eine galvanische Trennung durch einen automatisch durch die Steuereinheit (5) steuerbaren Schaltkontakt besteht.
