High Voltage Interlocking device Shutter Mechanism For 800mm Width Switchgear

The shutter mechanism is an important part of high-voltage distribution switchgear. At present, the shutter mechanism of domestic production mainly adopts the spring mechanism to operate the upper and lower movable doors. When the movable part is pushed forward so that the movable contact is drawn into the static contact, the spring linkage mechanism of the valve is driven by the linkage as the movable part hits the valve, and under the action of external force, the upper and lower valve plates move up and down respectively and open, so that the valve forms a synchronous counter-opening structure; conversely, when the movable part is pulled out, under the action of the spring, the linkage drives the valve plate to reset and cover the static contact completely.
