摘要： The gas insulated switchgear includes a gas insulated double main bus, bus sectioning and bus tieing gas insulated switchgear units, a main bus potential transformer and a main bus work use earthing switch for respective main buses. The bus sectioning and bus tieing gas insulated switchgear units are respectively constituted by a vertical type circuit breaker, and the main bus potential transformer and the main bus work earthing switch provided for one of two main buses. When the vertically disposed circuit breaker is used for the bus sectioning and the bus tieing gas insulated switchgear units, the entire device is decreased in size in the horizontal direction.

摘要： A gas insulated switchgear device of a double bus type which is accommodated in a metal container filled with SF.sub.6 gas includes first and second gas insulated main buses disposed horizontally and substantially in parallel with each other. Bus sectioning units section each of the first and second main buses into first and second sections. The bus sectioning units include auxiliary buses disposed outside of said first and second main buses. A branching bus connects one end of the first main bus with one end of one of the auxiliary buses via a circuit breaker. Another branching bus connects the other end of the first main bus with the other end of the one of the auxiliary buses. Still another branching bus connects one end of the second main bus with one end of another auxiliary bus. A further branching bus connects the other end of the second main bus with the other end of the other auxiliary bus. Potential transformers are provided along the branching buses.

摘要： A three-phase common tank type gas circuit breaker has a grounded tank filled with an insulating gas and accommodating three interrupter assemblies for three phases of the electric power. Each assembly includes a parallel electrical connection of an interrupter having stationary and movable contacts, a capacitor and a closing resistor. The interrupters for the three phases are disposed in spaced relationship circumferentially of the tank and have axes extending axially of the tank. The closing resistor for each phase is disposed on one side of the associated interrupter adjacent an adjacent interrupter for a different phase, while the capacitor for each phase is disposed on the inner or outer side of the associated interrupter, whereby the radial and axial dimensions of the grounded tank can be reduced.
