摘要：
A main circuit portions are arranged in the order of a breaking section fixed-side conductor, a breaking section movable-side conductor, a disconnecting section movable-side conductor, and a disconnecting section fixed-side conductor, and first and second grounding conductors are respectively provided for grounding the breaking section fixed-side conductor and the disconnecting section fixed-side conductor at both end portions of the apparatus. The arrangement of operating devices is set in the order of a first grounding-section operating device, a breaking-section operating device, a disconnecting-section operating device, and a second grounding-section operating device. In addition, a breaking section is supported by a single supporting insulator to reduce the number of creepage insulation portions.
