ABSTRACT:
Provided is a solid insulated disconnection switch including a base frame to which outside electrical equipment is electrically connected, a driving assembly generating rotating power, a shaft of which an outside surface has a screw thread and which is rotated by the rotating power generated by the driving assembly, a stator having a fixed contact point which is electrically connected to a main bus, a mover which is electrically connected to the external connection outlet of the base frame and moves back and forth in a straight line between the fixed contact point of the stator and a position which is separately disconnected from the fixed contact point of the stator by rotating the shaft, a spacer which is provided between the base frame and the stator, and a power transfer assembly which is provided between the driving assembly and the shaft to transfer the rotating power generated from the driving assembly to the shaft. The present invention makes it possible to reduce a size of the disconnection switch by using insulating solid material barriers between components of the disconnection switch instead of the insulating gas.
