摘要: A device for limiting short-circuit current in a consumer network having at least one supply line with a respective current feed point includes a disconnection point disposed in the at least one supply line so as to provide a first partial line and a second partial line in an event of a short-circuit fault. Each of the first and second partial lines has a respective associated current detector and at least one of the first and second partial lines has at least one current feed aggregate. The device includes a multiphase high-speed short circuiter having a current carrying capacity for short-circuit current intensities in the at least one supply line and a respective power circuit breaker connected in series with the high-speed short circuiter. The respective associated current detector is configured, upon detection of a short circuit in one of the first and second partial lines, to transmit a triggering signal so as to effect a short-circuit switching operation.

摘要: A device for limiting a short-circuit current in an alternating-current low-voltage installation includes one or more supply lines having power-supply points with power-supply aggregates protected by feeder switches. The supply lines are separated at an isolating point into two line sections in response to a short circuit fault. One or more polyphase high-speed short-circuiting devices are coupled to the isolating point, having a current carrying capacity sufficient for short-circuit current intensities occurring on the supply line. The high-speed short-circuiting device performs a short-circuit switching operation at the isolating point in response to a trip signal. Two power circuit breakers are each connected in series between each of the line sections and the high-speed short circuiting device. A current-sensing device is coupled to each line section. The current-sensing device detects the short circuit fault, and transmits the trip signal to the high-speed short circuiting device.
