    摘要: A high tension circuit breaker includes a gastight cylindrical insulating case filled with SF.sub.6 gas or the like and defining for each phase at least one current interrupting chamber. A fixed main contact and a fixed arcing contact are fixedly mounted within the chamber. Moving equipment of the circuit breaker includes moving main and arcing contacts and a member for moving the moving main and arcing contacts towards and away from the fixed main contact and the fixed arcing contact. A cylinder is fixedly mounted in said chamber and supports internally a movable blast piston and terminates in a blast nozzle facing the fixed contacts. A capacitor is disposed inside the circuit interrupting chamber optionally with a parallel connected varistor. A mechanism in the form of a switch including a fixed and a movable contact operates to insert the capacitor and the parallel connected varistor temporarily during both closing and opening of the circuit breaker contacts. The capacitor is constituted by a stack of capacitor components disposed in a fixed insulating tube mounted within the chamber. A first end of the stack is electrically connected to a first current terminal of the circuit breaker, and a second end of the stack is electrically connected to an electrode fixed to a piece of the moving equipment and electrically connected to a second current terminal of the circuit breaker. The electrode may be a tube coaxial with the case and internally of the case.

    摘要: An insulating stay comprises: a central core (1) having high electrical resistance and high tensile strength; a sheath (2) of high electrical resistivity and comprising fins (3) to offer a maximum resistance path to possible surface current losses; and end fittings (4). The central core is made of resin reinforced with long, continuous fibers, and advantageously of epoxy resin reinforced with glass fibers. The sheath (2) is made of a natural or synthetic polymer, and advantageously of EPDM elastomer. The stay is manufactured by coating the central core (1) with a high viscosity glue (8) having high longitudinal resistivity, then wrapping said glue-covered core in a hollow tube (5) of raw elastomer and placing the assembly in a mold (5) where said fins (3) are formed in the sheath (2) and where the raw elastomer (5) is polymerized by vulcanization or reticulation. The stay is intended for bracing electrical installations that need to be insolated and placed at some distance from the ground.
