Abstract
A gas insulated switchgear device includes a pair of main bus lines arranged in parallel; a pair of auxiliary bus lines arranged in parallel; three sets of circuit breakers each including at both ends thereof respective disconnecting switches, the three sets of circuit breakers being electrically connected in series between the pair of main bus lines via the pair of auxiliary bus lines; and a cable head provided at junction points between the disconnecting switches belonging to the respective adjacent circuit breakers. The pair of main bus lines and the pair of auxiliary bus lines are arranged in parallel with each other over a substantially horizontal plane near their installation plane, and the three sets of circuit breakers are vertical type circuit breakers and are disposed at one side of the pair of main bus lines and of the pair of auxiliary bus lines along their axial direction.
