Abstract (en)
[origin: US2003210508A1] The apparatus is intended for disconnection of a live electrical conductor and has an enclosure (3) and two power connections (1, 2) which are passed out of the enclosure (3). A conductor section (7) which connects the two power connections (1, 2) to one another and a propellant means are arranged in the enclosure interior (4). The propellant means is used to produce an amount of compressed gas which is sufficient to disconnect the conductor section (7) when a fault current occurs. The propellant means is kept free of combustible substances and is chosen such that the amount of compressed gas which is required for disconnection can be thermally released from the propellant means by the electrical work produced by the fault current. Since explosive substances are avoided in the apparatus, the apparatus can be produced, transported, installed and maintained completely safely. After being commissioned, the apparatus is distinguished by high operational reliability.
