Abstract
The utility model mainly provides a high voltage switch cabinet arc-resistant lift door device, and aims at solving the technical problem that a short cut suddenly happens when a reinforced screw door is unraveled and a middle door is not opened, then the middle door is rushed to be opened by arcing residual air pressure flow brought about by the short cut, and thus operation staffs are hurt by the rushed middle door. Mechanical component design of the high voltage switch cabinet arc-resistant lift door device ensures that the high voltage switch cabinet arc-resistant lift door device has enough mechanical strength. A door of a middle cabinet opens and closes freely so that the staffs do not worry being hurt by the door body rushed to be opened by air flow due to the fact that bolts are not tightened up. Therefore, troubles of accidents that hurt the staffs are thoroughly solved and thus an objective of protecting safety of the operation staffs is achieved.
Description
Technical field
