Patent number: 11574777Abstract: A switching apparatus for an electric grid includes first and second electric terminals, each having first and second electric branches having a plurality of switching devices. The first electric branch includes a first switching device switchable between open and closed states, which is driven by a current flowing along said first switching device and without receiving an external control signal or an external power supply, said first switching device switching from said closed state to said open state, when the current flowing along said switching apparatus exceeds a corresponding predefined threshold value or when the changing rate of the current flowing along said switching apparatus exceeds a corresponding predefined threshold value or upon a combination of these two conditions. A second switching device is connected in series with the first switching device and is switchable between closed and open states upon receiving a corresponding input control signal.Type: GrantFiled: December 13, 2021Date of Patent: February 7, 2023Assignee: ABB Schweiz AGInventors: Thorsten Strassel, Antonello Antoniazzi, Markus Abplanalp, Thierry Delachaux

DC current switching apparatus, electronic device, and method for switching an associated DC circuit
Patent number: 9484168Abstract: Exemplary embodiments are directed to a direct current switching apparatus including at least a first mechanical switching device which is suitable to be positioned along an operating path of an associated DC circuit and includes a fixed contact and a corresponding movable contact which can be actuated between a closed position and an open position along the operating path, wherein an electric arc can ignite between the contacts under separation. The switching apparatus includes an electronic circuit having a semiconductor device which is suitable to be positioned along a secondary path and connected in parallel with the first mechanical switching device. The electronic circuit can be configured to commute the flow of current from the operating path to the secondary path and extinguish an electric arc ignited when the movable contact separates from the fixed contact when the first mechanical switching device fails to extinguish the same.Type: GrantFiled: May 6, 2014Date of Patent: November 1, 2016Assignee: ABB S.P.A.Inventors: Davide Pessina, Romeo Bianchetti, Rudolf Gati, Thorsten Strassel -
