  • Patent number: 7589289
    Abstract: Disclosed are a solid-insulated disconnection switch and a solid-insulated switchgear using the same. The solid-insulated switchgear using the solid-insulated disconnection switch according to the present invention can have an eco-friendly characteristic and a small size by solid-insulating each unit, a disconnection switches and earth switch constituting each unit. In the solid-insulated switchgear according to the present invention, each unit and each part constituting each unit are standardized so as to be interchangeable to each other, thereby implementing a simple manufacture. Furthermore, the solid-insulated switchgear can be manufactured according to an installation environment and a user's various demands, and can have an enhanced maintenance/repair characteristic.
    Type: Grant

  • Patent number: 7189933
    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.
