摘要： The present disclosure provides controllers for power distribution network circuit interrupting devices and provides electronic control circuits for inclusion in such controllers. The electronic control circuit has a boost circuit, a capacitor storage unit and a pulse width modulator control circuit. The boost circuit boosts an input voltage to a value to supply sufficient energy to a protective relay solenoid to energize the solenoid. The capacitor storage unit stores the boosted voltage from the boost circuit. The pulse width modulator control circuit is responsive to a control and enable circuit to selectively enable energy from the capacitor to energize the one or more protective relays in power distribution system circuit interrupting device.

摘要： A gas-blast switch has a housing which encloses an arcing chamber, an accumulator space and an expansion space. Two relatively moveable contact members are arranged in the housing. One of the contact members moves through a nozzle. The nozzle is formed of and defined by two moveable nozzle parts, the relative position of which determines the size of a discharge cross-section in the nozzle. During a switching-off operation, the moveable contact member moves out of the arcing chamber and quenching gas flows from the accumulator space into the expansion space, through the arcing chamber, i.e. the nozzle. The size of discharge cross-section of the nozzle varies through movement of the nozzle parts which respond to pressure created in the switch, without the assistance of elaborate compression springs. To this end, the nozzle parts are freely mounted to move in response to pressures generated in the switch and they are disposed in the gas path between the arcing chamber and the accumulator space.

摘要： A disconnect switch and grounding apparatus therefor particularly adapted for use in gas insulated substations. The disconnect switch comprises a chamber having a pair of electrical conductors entering the chamber. Supporting the conductors and insulating them from contact with the chamber itself are insulators, which may be sealingly placed so as to prohibit the escape of the gas. A fixed contact member electrically attached to the first of the pair of conductors and a movable contact member is electrically attached to the second pair of conductors. A movement mechanism to move the movable contact members so as to make and break contact with the fixed contact member. A grounding strip electrically attached to the movable contact member, positioned so as to come in contact with the chamber wall immediately after the breaking of contact between the fixed and the movable contact members. The movement mechanism comprises a linkage having two links, the first link attached at one end to the movable contact member and the other end connected to the second link, the other end of the second link being connected to a shaft member. The shaft member sealingly extends through the wall of the chamber having attached to it on the outside of the chamber a handle for causing the shaft to rotate. The shaft upon rotation engages the linkage causing the movable contact member to make or break contact with the fixed contact member and respectively the ground strip to move away from or come in contact with the wall of the chamber.

摘要： A structural component such as nozzle-forming member to be utilized in conjunction with the arc quenching chamber of an electrical circuit breaker operating with a pressurized gaseous fluid such as SF.sub.6 and made from a polytetrafluoroethylene composition that is gas-emissive under influence of heat generated by the arc in the vicinity of the nozzle is provided with a system of gas-conducting passageways to permit such gas to escape from sub-surface cavities formed by deterioration of the composition rather than accumulate therein which leads ultimately to undersirable chipping off of pieces of the surface. These passageways may be constituted by a system of blind holes or by a system of grooves.
