摘要： To provide a high-voltage switch which can switch off in a very short time, namely in a half-period, rapid severing of the isolating screws (36) is utilized, and the high-voltage switch is designed so that the switch-off and switch-on device contains at least one isolating screw (36) by means of which a prestressed rod (28) connected to the movable contact of the high-voltage switch can be released. The half-period high-voltage switch according to the invention is used appropriately in switching systems where the half-period high-voltage switch is connected in series with at least one power circuit-breaker. The advantage is to be seen especially in the use of the high-voltage switch in switching systems where it permits a limited short-circuit cut-out capacity.

摘要： A high-voltage circuit-interrupter has a contact arrangement operating in compressed gas contained in a sealed vessel. The contact arrangement comprises a pair of spaced aligned tubular fixed contacts respectively connected to the terminals of the interrupter, and a pair of separable rooting electrodes mounted within the tubular fixed contacts and electrically connected respectively to them. A tubular bridging contact sleeve is slidably mounted on the tubular bridging contacts and is movable between a closed position bridging the spaced ends of the tubular contacts and an open position withdrawn from one of them to open a gap therebetween. The circuit-interrupter operating mechanism is arranged, for opening the interrupter, to withdraw the bridging contact sleeve from one of the fixed contacts and to initiate a gas blast through the gap so opened into the interiors of the fixed contacts and simultaneously or subsequently to withdraw one of the rooting electrodes from the other, so that the arc drawn between the bridging contact sleeve and one tubular fixed contact is transferred to the separated rooting electrodes and is then extinguished.

摘要： An electrical switch of the type which utilizes a pressurized gas such as SF6 working in a closed system for blasting the switch contacts with the gas in order to facilitate extinction of the arc includes high and low pressure gas tanks, the gas being stored in the high pressure tank and being delivered through a gas blast valve to a housing enclosing the switch contacts and which is located in the low-pressure tank. The gas after blasting the switch contacts flows from the switch contact housing into the low pressure tank. To facilitate servicing of the gas blast valve without loss of gas from either the high or low pressure tanks, the interior of the blast valve including the movable parts and seals is made accessible from the exterior of the tanks and provision is made for sealing off the two tanks from the interior of the blast valve.
