Described vacuum interrupter is horizontally disposed with, and upper outlet and described vacuum interrupter be arranged in parallel.
Rotation connection structure is be opened in the hinge hole that the axis in described upper outlet extends along the longitudinal direction.
Pole also comprises the lower outlet of the vertical setting be connected with described vacuum interrupter, and packaging body comprises the diameter being from the bottom to top located at described lower outlet periphery and becomes large taper positioning sleeve gradually.
Isolating switch also comprises the grounding contact being arranged at described packaging body upper end.
The left tank wall of described gas tank, right tank wall are connected with horizontally disposed main bus bar by entrance bushing, left tank wall or right tank wall are provided with static contact seat, described fixed contact is arranged on described static contact seat, and fixed contact connects row by bus and is connected with described main bus bar.
In the utility model, the technical scheme of pole is:
Pole, comprises packaging body and the vacuum interrupter that is fixedly arranged in packaging body and upper outlet, and upper outlet is provided with the exposed rotation connection structure for being hinged and connected with the movable touch knife of corresponding isolating switch.
Upper outlet and described vacuum interrupter be arranged in parallel.
Rotation connection structure is be opened in the hinge hole in described upper outlet.
The beneficial effects of the utility model are: in the utility model, the upper outlet of pole is provided with exposed rotation connection structure, movable touch knife can directly be articulated with on the rotation connection structure of outlet, go up outlet like this and constitute contact knife seat, achieve the Integrated design of contact knife seat and vacuum interrupter, middle contact knife seat, arc control device connect row and the scattered setting of vacuum interrupter compared to existing technology, substantially increase the compact conformation of product.
Further, horizontally disposed vacuum interrupter and upper outlet will more be conducive to the whole height reducing product.
Further, on the left tank wall that static contact seat is arranged at gas tank or right tank wall, static contact seat connects row by bus and is connected with main bus bar, and such movable touch knife can not to be delivered on main bus bar the active force of fixed contact but to be born by casing, ensures that main bus bar can not be out of shape.
