摘要： A switching apparatus wherein the life and the reliability of an electric contact are improved by fundamentally suppressing formation of black powder and activation of the surface of the contact by a chemical reaction. Microcapsules in which organic acid or organic acid precursor from which organic acid is produced as time passes is enclosed are placed into the internal space of an enclosed case so that organic compounds produced on and in the proximity of contact surfaces is oxidized with organic acid which escapes from the microcapsules and vaporized in the enclosed case without forming a film on the surfaces of the contacts to suppress activation of the surfaces of the contacts.

摘要： An isolating switch of a metalclad installation having an earthed metal enclosure is filled with a high dielectric strength gas. The isolation gap "d" separating the stationary contact from the movable sliding pin is surrounded by an annular electrode fitted between this isolation gap "d" and the enclosure. The annular electrode extends over the whole length of the isolation gap "d" and is electrically connected to the stationary contact to prevent any migration of the arc drawn between the contacts towards the earthed enclosure. The metal enclosure is advantageously spherical in shape, the contacts being disposed appreciably in the center of the sphere.

摘要： A contact arrangement is disclosed for a high voltage power circuit breaker wherein compressed gas is blown through the arc developed when the breaker is switched. The contact arrangement includes at least two contact pieces having respective hollow interiors for accommodating the discharge of the gas blown through the arc. Arcing electrodes between which the arc is drawn when the breaker is switched to the open position are electrically and mechanically joined to the contact pieces respectively. Each arcing electrode and the corresponding contact piece conjointly define an interface whereat the arc electrode is joined to the electrode piece. An electrically conductive supplement is contained in the electrodes in the region thereof next to the interface. The supplement comprises at least one metal and the arcing electrodes are made of carbon bodies and have a nozzle-like configuration. With the contact arrangement of the invention, increased mechanical strength is imparted to the graphite electrode and large differences in conductivity at the interface are obviated.
