摘要： Gas insulated substation system fully adaptable for orderly expansion for increasing the interrupting rating of an installation. A plurality of basic modular units are readily connected in series relationship in a manner to promote an efficient utilization of space and in which arrangement the servicing of each individual unit does not require any additional space over that which is required by a single unit. The operation of the interrupting contacts and blast valve for all units of a single phase of the system is accomplished by means of a single operator. The arrangement provides the required spacing between external bushings of the interrupter units in the system and between the bushings of the individual units.

摘要： A non-restricting conductor filtering system is provided in the high-pressure barriered area of a high-voltage compressed-gas circuit interrupter to prevent damage to the barrier in the event of blast-valve failure, and a consequent differential-pressure drop across the barrier. The filtering system not only permits a ready equalization of the pressure across the barrier, in the event of blast-valve failure, but the filtering prevents any small metallic particles from the contact region from entering into the annular highpressure space between the high-voltage conductor and the surrounding barrier member during subsequent repressurization of the high-voltage, high-pressure area portion of the circuitbreaker.

摘要： A high-voltage compressed-gas circuit interrupter is provided including a tank structure, and a terminal bushing extending therein supporting an arc-extinguishing unit. A high-pressure gas-reservoir chamber is disposed adjacent the inner end of the terminal bushing for close proximity to the separable contact structure of the arc-extinguishing unit. Additional features include a blast-valve means, disposed in close proximity to the stationary contact structure, and the partial storage of high-pressure gas within the hollow stud of the terminal bushing to prevent liquefaction of a liquefiable gas under low-ambient temperature conditions. Another feature of the invention includes a rotating operating rod for low inertia, and the pilot-valve operation of the blastvalve mechanism by a cam interconnection between the pilot-rod linkage and the rotating operating tube.

摘要： Electrical switchgear apparatus using a pressurized arcquenching and insulating gaseous medium particularly SF6 wherein the gas is maintained at high pressure in a switching chamber and is transferred to an adjacent low-pressure chamber during a switching operation, and wherein the gas is supplied to the switching chamber from a storage container via a high-pressure supply line, then returned via a low-pressure return line from the low-pressure chamber to a compressor for re-compression and feed back via a feed line into the storage container. To prevent condensation of gas in its high-pressure state which may become trapped in the gas supply line between the storage container and the switching chamber, and also similarly trapped in the gas feedback line between the compressor and the storage container, vent lines are provided. A first vent line including a flow restrictor and non-return valve interconnects the gas supply line and the low-pressure return line, and a second vent line including a flow restrictor interconnects the gas feedback line with the low-pressure return line.

摘要： The arc-extinguishing gas of a compressed-gas circuit interrupter is prevented from liquefying by effecting the circulation of the high-pressure gas by a forced flow through a nozzle causing the gas to circulate through a heating element. The gas, for example, may comprise sulfur-hexafluoride (SF6) gas, or other suitable arc-extinguishing gases, subject to the hazard of liquefaction.

摘要： Discloses an airblast circuit breaker comprising interrupter tanks at high voltage filled with high-pressure air and provided with terminal bushings filled with a dielectric gas other than air. The tanks are mounted on hollow insulating columns through which air lines of insulating material extend to supply highpressure air to the tanks. A current transformer adjacent the columns has an insulating housing that is pneumatically interconnected with the bushings in the high-voltage region and is filled with dielectric gas of the same type as the bushings to serve as a reservoir for supplying the bushings with dielectric gas. Also discloses special means for mounting and sealing the high-pressure air line with respect to its column and tank.

摘要： 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.
