    摘要: A switchgear or control gear includes at least one first compartment; a plurality of removable modules; a plurality of main switchgear or control gear components; and a plurality of auxiliary switchgear or control gear components. The plurality of main switchgear or control gear components includes at least one main busbar system, at least one three position linear or rotational movement disconnector, at least one circuit breaker, and at least one cable connection. The plurality of auxiliary switchgear or control gear components includes at least one disconnector drive and at least one circuit breaker drive. The plurality of removable modules are configured to be mounted horizontally within the at least one first compartment at a plurality of horizontal locations. Movement of a removable module from its horizontal location, the movement including a vertical movement, is configured to move the one or more auxiliary components housed in or associated with that module.

    摘要: An improved piston-type fluid-blast circuit interrupter is provided having a stationary operating cylinder, within which reciprocates a movable piston assembly carrying the movable contact assembly of the interrupter. Electromagnet means including three accelerating coils, one movable with the piston assembly, another located in the closed end of the operating cylinder, and a third coil movable with a driver unit, are all connected in series during the opening operation of the interrupter. The driver unit is mechanically connected through the closed end of the operating cylinder with the movable piston assembly. The magnetic attraction between the piston coil and the coil at the closed end of the operating cylinder, and the magnetic repulsion forces between the coil at the closed end of the operating cylinder and the coil carried by the driver unit, all contribute to magnetically assisting the fluid-driving motion of the piston assembly and so effecting interruption. The movable contact structure comprises a main movable contact and an inner movable arcing probe movable together and insulated from each other with the three accelerating coils connected between the main movable contact and the movable arcing probe in the closed position of the interrupter.

    摘要: An apparatus includes a housing having a gas-insulated compartment and a non-gas-insulated receptacle therein. The receptacle is disposed adjacent to the gas-insulated compartment and configured for removable insertion of a circuit interrupter assembly therein. A bus is disposed in the gas-insulated compartment, and a contact is disposed in the receptacle, electrically coupled to the bus in the gas-insulated compartment and configured to mate with a terminal of the circuit interrupter assembly when the circuit interrupter assembly is installed in the receptacle. The receptacle may be configured for insertion of an insulation-encapsulated circuit interrupter pole unit and the apparatus may include at least one flexible insulation member attached to a side wall of the receptacle and configured to engage a sidewall of the pole unit.
