摘要： An apparatus for use in a power delivery system, the apparatus comprising: a DC circuit breaker having first and second terminals and configured to automatically switch from a closed state to an open state during an overcurrent condition; a disconnector switch in series with the DC circuit breaker, the disconnector switch having a first terminal for connecting to a first polarity terminal of a DC power supply, a second terminal for connecting to a second polarity terminal of the DC power supply and a common terminal connected to the first terminal of the DC circuit breaker, the disconnector switch having at least a first position in which the first terminal is connected to the common terminal and a second position in which the second terminal is connected to the common terminal; and an interlock mechanism coupled to the DC circuit breaker and the disconnector switch, the interlock mechanism configured to disable the DC circuit breaker from automatically switching from the closed state to the open state during the overcurrent condition when the disconnector switch is in the second position.

摘要： The invention relates to an overvoltage protection arrangement comprising a horn spark gap located in an insulating housing, with a deionization chamber for arc quenching, wherein the deionization chamber has a plurality of spaced quench plates and a trigger electrode is located in the ignition region of the horn spark gap, wherein a disconnecting device comprises a fusible link that is located in the region of the deionization chamber and is exposed there to a loading of a power follow-on current, wherein the fusible link holds a disconnecting element, preferably supported by spring force, in a first position, and on melting releases this disconnecting element in such a way that the disconnecting element adopts a second position wherein, on reaching the second position, an electrical connection to the trigger electrode is interrupted and the trigger electrode is thereby disconnected.
