20070158310 - Gas exhaust for circuit breaker: The gas exhaust comprises a generally cylindrical shaped casing (26) closed by a bottom (18, 22) at one end and with openings (30) to allow gas to escape. A duct (16) is arranged in the casing (26) to delimit a central passage inside the duct, and an annular passage (42)... Agent: Thelen Reid Brown Raysman & Steiner LLP

20070158311 - Three-position ground switch: A high or medium voltage electrical switch, particularly a GIS type isolating switch with three switching positions and a grounding position, includes a switching element in a closed and sealed enclosure that can be filled with a dielectrically insulating gas, containing a mobile switching element free to move along an... Agent: Oblon, Spivak, Mcclelland, Maier & Neustadt, P.C.

20070151952 - High-voltage outdoor bushing arrangement: A high-voltage outdoor bushing configuration includes an electrically insulating casing and an electrically conductive housing. An isolating gap is located inside the electrically conductive housing. The isolating gap interrupts a phase conductor into first and second sections. A switching piece or an element of a multi-part switching piece can be... Agent: Lerner Greenberg Stemer LLP

20070151953 - Compressed-gas insulation switching device: A compressed-gas-insulated switching deviceincludes a grounded encapsulating housing formed of an electrically conductive material and an electrically insulated phase conductor disposed inside the encapsulating housing. First and second flanges are disposed on the grounded encapsulating housing. Insulating housings respectively containing a switch disconnector and an interrupter unit of a power...
