More Information
Summary:An electrical switching device is filled with a dielectric insulating medium comprising an organofluorine compound, in particular a fluoroether, a fluoroarnine, a fluoroketone or a fluoroolefin, and comprises at least an arcing contact arrangement with a first arcing contact and a mating second arcing contact. At least a first intermediate volume is provided downstream from the first arcing contact, and/or at least a second intermediate volume is provided downstream from the second arcing contact. The intermediate volumes are for intermediate pressure enhancement and exhaust gas jet formation for turbulent convective heat transfer to metal walls of the exhaust system. In embodiments, the first and/or second intermediate volume is delimited by at least one moveable wall arranged transversally to the longitudinal axis and shiftable parallel to it by an actuation device.
