    Abstract: A compressed-gas circuit interrupter has a generally U-shape with interrupting elements, or terminal-bushing structures, disposed in the upstanding legs of the ''''U,'''' depending upon the rating requirements; and a grounded high-pressure chamber constitutes the lower bend of the U-shaped circuit interrupter. The compressed-gas circuit interrupter is of the dual-pressure type in which the one or more pairs of contacts are separated in a high-pressure gaseous environment, and the high-pressure gas exhausts through one or both of the separable contacts themselves. Downstream blast valves control the continued exhaust of gas through the separable contact structure, and in the fully open-circuit position of the interrupter, the contact space contains high-pressure gas, resulting in reduced separation distance between the separated contacts. For the lower ratings, a terminal bushing, preferably of the gaseous type, constitutes one of the legs of the ''''U'''' and the interrupting elements are disposed along the other leg of the U. For the higher ratings, both legs of the U may comprise one or more serially related interrupting elements to provide, where desired, a number of serially related arc-extinguishing units. The movable contact structure is preferably actuated pneumatically by a piston structure disposed at the upper end of the arc-extinguishing side of the interrupter, which is controlled by a three-way tripping control valve initiated by an insulating operating rod extending down to ground potential, and mechanically connected to the other phase units of the circuit interrupter, a common valve actuator employed. The legs of the U comprise an outer weatherproof insulating shell and an inner insulating tube, which may be under tension, surrounding the serially related arc-extinguishing units. As stated, the inner insulating tube contains high-pressure gas immediately surrounding the separable contact structure, so that high-pressure gas is immediately available at the contacts for the interrupting operation upon their separation.

    Abstract: 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.

    Abstract: 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.
