摘要： An arc-extinguishing unit is provided in a high-pressure gaseous environment having a pair of separable contacts, which when closed provide a primary blast valve, which prevents an exhausting flow of high-pressure gas through the interior of the contacts. Pneumatically connected with the interior of at least one of the separable contacts is a secondary blast valve, which is open in the closed-circuit position of the interrupting device. During the opening operation, upon separation of the separable contacts, the secondary blast valve begins to close, so that in the fully open-circuit position of the interrupter, the contacts will be separated, and the one or more secondary blast valves will be closed to prevent continued exhausting flow through the contacts from the high-pressure region externally of the contacts. The one or more secondary blast valves are mechanically latched in their open position, and a blast-valve activator, moving with the moving contact structure, compresses spring means tending to close the secondary blast valve, and additionally releases the latches at a predetermined point of time in the opening operation to thereby permit a delayed closing action of the secondary blast valve.

摘要： A separable contact structure is provided for a high-voltage compressed-gas circuit interrupter involving at least one of the contacts being tubular to provide a gas flow therethrough, and having a liner component therein. To facilitate movement of the terminal end of the arc, a relatively thin tubular member is inserted interiorly of the hollow contact, and, by electrically connecting the same to the inner anterior end of the hollow contact, the magnetic field situation is such that the terminal end of the arc is encouraged to move axially along the relatively thin tubular liner member to thereby effect considerable elongation of the established arc, and thereby to effect the extinction of the same by a more effective gas flow condition. As a further extension of this same concept, a cooperable tubular contact structure may be provided, through which gas also exhausts, and a similar relatively thin tubular liner member may also be associated therewith to act in a similar manner.
