Patent number: 9450394Abstract: A high voltage DC circuit breaker includes a semiconductor switching assembly in series with a mechanical switch. When the semiconductor switching assembly is switched off due to a current fault, a residual current flowing through arresters of the semiconductor switching assembly is switched off by the mechanical switch. A capacitor arranged parallel to the mechanical switch leads to passive resonance effects, which in turn induce current zero crossings in its arc. The current zero crossings allow for reliable extinguishing of the arc. The mechanical switch can be an AC circuit breaker.Type: GrantFiled: June 24, 2013Date of Patent: September 20, 2016Assignee: ABB Technology AGInventors: Daniel Ohlsson, Emmanouil Panousis, Jürgen Häfner, Markus Bujotzek, Per Skarby

Publication number: 20140005053Abstract: To limit current rise in a high voltage DC system, the current can be led through a current rise limiter. An exemplary current rise limiter can have an inductance that increases with the current I through the current rise limiter and/or with a time-derivative dI/dt of the current I. In such a system, the current rise limiter can have minor influence on normal operation, but can limit the rise rate of the current in the event of a fault to, for example, provide more time to switch off the current.Type: ApplicationFiled: September 4, 2013Publication date: January 2, 2014Applicant: ABB Technology AGInventors: Christian Schacherer, Markus Abplanalp, Markus Bujotzek, Emmanouil Panousis

Publication number: 20130265693Abstract: A medium or high-voltage circuit breaker is provided. An arc-extinguishing fluid is stored in a pressure chamber, which is made up by an arcing chamber of the circuit breaker where an electrical arc is extinguished. No tubings or other conduction devices for pressurized fluids are necessary during current interruption. This speeds up contact separation and arc extinguishing. In a first, closed position of the circuit breaker, the pressure chamber is delimited by a sealing wall which is fixed to a movable first arcing contact. The sealing wall acts as a valve and as a piston at the same time, because it opens the outflow of pressurized arc extinguishing fluid and it concurrently actuates arcing contact separation. The arcing chamber enables the stored pressurized arc extinguishing fluid to perform fast contact separation within a few milliseconds and extinguishing a gaseous arc on the same timescale.Type: ApplicationFiled: April 5, 2013Publication date: October 10, 2013Applicant: ABB Technology AGInventors: Emmanouil PANOUSIS, Marcelo BUFFONI, Markus BUJOTZEK, Bernardo GALLETTI
