摘要： A high tension circuit breaker containing a dielectric gas under pressure, the circuit breaker being of the type comprising at least one interrupting chamber comprising an insulating envelope filled with said gas and containing a fixed assembly including a fixed main contact (2) and a fixed arcing contact (4), and a moving assembly including a moving main contact (7) and a moving arcing contact (5), the interrupting chamber also containing a pair of secondary contacts and a blast cylinder opening out into a blast nozzle. The circuit breaker further includes first means (37, 38,104) for limiting the maximum separation distance between the secondary contacts to a value which is less than the maximum separation distance between the arcing contacts, and second means (60, 101) for preventing any arcs being struck during closure.

摘要： A gas-blast circuit breaker has two switching elements disposed in a casing filled with arc-extinguishing gas and capable of being brought into or out of engagement with each other along one axis. One of these two switching elements defines an arc-extinguishing jet nozzle and can be guided during switching-off through a heating chamber. The heating chamber stores which is formed by heating up arc-extinguishing gas pressurized gas by means of a switching arc. When low currents are switched, a comparatively high pressure is built up in the heating chamber. On the other hand, a relatively low pressure develops during switching of large currents. This results from the inclusion in the second switching element of an insulation capping which extends around the outer surface and reaches to the front end face thereof, an arcing contact on its outer surface which receives the switching arc during the heating up phase of the switching process and also an arc-extinguishing contact which is separated from the arcing contact by the capping. The root point of the switching arc is commuted, shortly before the current to be switched off passes through zero, to the arc-extinguishing contact.

摘要： A circuit breaker switch for periodic current has a stationary contact connected to a first current terminal; a movable contact connected to a second terminal and having a closed position in which it engages the stationary contact and an open position in which it is separated from the stationary contact, an actuating device for moving the movable contact; a locking device having an operative position in which it immobilizes the movable contact in its closed position and an inoperative position in which it is clear of the movable contact; and a current intensity-responsive device connected to the locking device for moving the locking device from its inoperative position to its locking position when the intensity of current flowing through the circuit breaker switch exceeds a first predetermined value and for moving the locking device from its locking position into its inoperative position when the intensity reaches a second predetermined value.

摘要： An improved method for quenching an arc in an AC circuit breaker having an arc chamber in which the arc rotates in a quenching medium between open electrodes having ends close together in which the arc is caused to generate during its rotation, through a heating of the quenching medium, an over-pressure which is maintained beyond the zero crossing of the AC current with the gas flow produced by the over-pressure use for blasting the arc in the nozzle. Various embodiments for use in medium and high voltage switching installations which permit the switching of large currents with a simple and inexpensive arrangement are illustrated.
