<P>PROBLEM TO BE SOLVED: To realize a miniaturization and cost reduction in a vacuum switchgear system. <P>SOLUTION: The vacuum switchgear system comprises two or more vacuum switchgears which have a vacuum housing for accommodating two or more switches chosen from a disconnector or a load switch, a grounding switch, and a vacuum breaker. The above vacuum switchgears have contact terminals, and the vacuum switchgears constitute different types of vacuum switchgears. The vacuum switchgears are divided into a power receiving side and a power distribution side, and the vacuum switchgears are connected with the elements chosen from an adjoining vacuum switchgear, a lightning arrester and PCT via the insulation joint conductor, which has contact terminals at both ends and can be attached to and detached from the terminals of the vacuum switchgears. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
