摘要： A safety device for preventing overpressures in low pressure reservoirs receiving compressed gas through a feedline connected to a high pressure source is disclosed including a spherical stopcock in the feedline. A cylinder is provided in pressure communication with the low pressure reservoir with a spring-biased piston arranged within the cylinder. Connected to the piston and projecting from the cylinder is a toothed rack having teeth which intermesh with teeth of a rotatable, toothed segment connected to the stopcock. Motion of the piston, in response to pressure changes in the low pressure reservoir, causes the toothed rack to open or close the stopcock. A hole in the wall of the cylinder allows excess compressed air or gas to escape to the atmosphere in the event that the maximum allowable pressure within the low pressure reservoir is exceeded.

摘要： A gastight seal arrangement for an actuating rod that passes through a wall of a gas-filled enclosure is described. The actuating rod includes a pair of flanges that are spaced longitudinally of the rod and are positioned on opposite sides of the wall of the enclosure. Impact seals on the interior and exterior of the wall surround the actuating rod and are engaged by the respective flanges corresponding to the position of the rod. Additional seal members are provided in the interior of the wall to prevent leakage along the surface of the actuating rod.

摘要： A gastight dynamic seal sealing the pressurized enclosure of a compressed-gas circuit interrupter to a rotatable through control shaft. Radial partition walls of a sleeve surrounding the shaft define a plurality of liquid-filled gas-trap chambers separated by small throttle passageways causing the gas leaking through elastomer joints disposed in some of said chambers to be dissolved in the liquid in degressive concentration, going from the pressurized side of the seal towards the atmospheric side thereof.

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.
