摘要： The gas-blast circuit breaker, which is preferably provided for switching medium-high voltages, has two arcing and two rated-current contacts each of which are located in a housing filled with insulating gas and operate in conjunction with each other. For purposes of a compact construction, electric connections, are carried into the interior of the housing transversely to the direction of movement of one moving contact of the two arcing contacts. The driving energy required for a switching process is intended to be kept as low as possible while retaining the compact construction. This is achieved by the fact that the moving rated-current contact is rotatably supported and that a drive, acting on the moving arcing and the moving rated-current contact has two rods which are pivoted at a driving crank, one of which rods is pivoted at the moving arcing contact and the other one of which is pivoted at the moving rated-current contact. In this arrangement, the two insulating rods are pivoted at the driving crank in such a manner that, during the disconnecting process, a thrust crank formed by the driving crank, one rod of insulating material and the moving arcing contact passes through a dead-center position before the disconnected condition has been reached.
摘要翻译：优选地设置用于切换中高电压的气体断路器具有两个电弧和两个额定电流触点，每个触点和两个额定电流触点都位于装有绝缘气体的壳体中并且彼此结合操作。为了紧凑的结构，电连接件横向于两个电弧触点的一个移动触点的移动方向被承载到壳体的内部。切换过程所需的驱动能量尽可能地保持在尽可能低的同时保持紧凑的结构。这是通过以下事实实现的：移动额定电流触点可旋转地支撑，并且作用在移动电弧和移动额定电流触点上的驱动器具有两个在驱动曲柄上枢转的杆，其中一个杆枢转在移动的电弧触点处，另一个在移动的额定电流触点处枢转。在这种布置中，两个绝缘杆在驱动曲柄处以这样的方式枢转，即在断开过程期间，由驱动曲柄，一根绝缘材料棒和移动的电弧触点形成的推力曲柄通过死角达到断开连接状态前的位置。

摘要： An improved insulating material is provided. The insulating material is a mixture of an insulating fluid and solid insulative bodies. The insulating material exhibits desirable insulating, conformal coating, surface adhesion, and low-viscosity characteristics. For example, when the insulating material is used to fill the cavity of a hollow insulator, the insulating material prevents any moisture that enters the insulator from adhering to the walls that define the cavity; thus maintaining the insulating qualities of the insulator. In the event that some of the fluid is lost through leakage, the insulating material also aids in preserving the insulating qualities of the insulator.

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.

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.
