ABSTRACT:
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.
