Abstract: An electrical switching device (1) comprises: a longitudinal axis (z), a contact arrangement with a first contact (3) and a second contact (4), an insulating element (8a) enclosing at least partly the first contact (3), and a first auxiliary insulating element (8b) enclosing at least partly the second contact (4). An arcing volume (5) is defined between the first contact (3) and the second contact (4) and delimited by inner walls of the insulating element (8a) and of the first auxiliary insulating element (8b) and is connected to a pressurized gas volume (6) via a first channel (7), in such a way that an insulating fluid can travel between both volumes (5, 6) through the first channel (7). The first channel (7) has a first section (7a) opening out in the arcing volume (5) and a second section (7b) opening out in the pressurized gas volume (6), the first section (7a) being delimited by a front face (9b) of the first auxiliary insulating element (8b) and at least by a front face (9a) of the insulating element (8a). In the first auxiliary insulating element (8b) at least a first bypass channel (2) is provided, which opens up on one side in the second section (7b) of the first channel (7) and opens up on the other side in a first transitional area (11) between the front face (9b) of the first auxiliary insulating element (8b) and an inner wall (9c) of the first auxiliary insulating element (8b).

Abstract: An improved medium- or high-voltage circuit breaker (100) is disclosed which is capable of faster contact separation and arc extinguishing performances while the setup of the circuit breaker is simplified. This is achieved by means of an arc-extinguishing fluid (10) stored in a pressure chamber (4), which is at least in part made up by an arcing chamber (3) of the circuit breaker (100) where an electrical arc is extinguished. No tubings or other conduction means 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 (100) the pressure chamber (4) is delimited by a sealing wall (30) which is fixed to a movable first arcing contact (1). The sealing wall (30) acts as a valve and as a piston at the same time, because it opens the outflow of pressurized arc extinguishing fluid (10) and it concurrently actuates arcing contact separation. Proper design and dimensioning of the arcing chamber (4) enables the stored pressurized arc extinguishing fluid (10) to perform very fast contact separation within few ms as well as extinguishing a gaseous arc (11) on the same timescale.
