Abstract: A switchgear enclosure has a case with a front face that surrounds an opening in the case. A flange extends from the front face and has a first surface adjacent to the opening and a second, opposing surface. At least the second surface is disposed transversely with respect to the front face. A door has a door bracket. A gasket is coupled the door bracket and forms an endless loop sized larger than a size of the opening in the case. The gasket has a seal portion. When the door is closed, the seal portion compresses against the second surface of the flange to provide a seal around the opening, and in the event of an arc in the case causing pressure to be exerted on the door, the gasket moves with the door, with the seal portion sliding along the second surface, maintaining the seal around the opening.

Abstract translation: 开关柜具有壳体，其前表面围绕壳体中的开口。 凸缘从前表面延伸并且具有与开口相邻的第一表面和第二相对的表面。 至少第二表面相对于前表面横向设置。 门有一个门支架。 垫圈联接在门支架上，并形成一个大小大于箱体开口尺寸的无限循环。 垫圈具有密封部分。 当门关闭时，密封部分压靠凸缘的第二表面以提供围绕开口的密封，并且在引起压力施加在门上的电弧的情况下，垫圈与门一起移动 密封部分沿着第二表面滑动，保持围绕开口的密封。
