Patent ID: 7425687

Claim:
A vacuum insulated switchgear comprising a plurality of single phase vacuum insulated switchgear modules, each of the single phase vacuum insulated switchgear modules comprising: a vacuum container; a vacuum insulated switch, accommodated in the vacuum container, having a movable contact connected to a movable electrode and a fixed contact connected to a fixed electrode for interrupting and closing current; an operating rod connected to the movable electrode and connected to a magnetic drive mechanism; and a connecting mechanism comprising a vertical connecting means and a lateral connecting means for connecting the operating rod together with the operating rods of other single phase vacuum insulated switchgear modules and for connecting together the connecting mechanisms of the vacuum insulated switchgear modules; characterized in that: the magnetic drive mechanism and the connecting mechanism are aligned on a vertical straight line of the vertical connecting means, each of the magnetic drive mechanisms has a rectangular parallelepiped shape when viewed from the top, and each of the single phase vacuum insulated switchgear modules is operable separately via the magnetic drive mechanism thereof before assembling the single phase vacuum insulated switchgear modules into the vacuum insulated switchgear by connecting together the lateral connecting means.
