BLOWOUT PANEL FORCED OPENING SYSTEM
To prevent an overload of an electric motor upon moving a blowout panel.SOLUTION: A forced opening system 100 comprises: a blowout panel 16 that is installed in an opening 13 of a building (a nuclear reactor building 11); a shielding body (a shielding door 14) that moves along an outer wall 12 of the building; a forced opening mechanism 20 that causes the blowout panel to move to a more outer side retreat position than a closed position when closing the shielding body; a detection unit (a winding end limit switch 52b) that detects a movement of the blowout panel to an outward position rather than the closed position; and a control unit 50 that controls an operation of an electric motor (an electrically-driven winch 21) of the forced opening mechanism. The control unit is configured to cause the blowout panel to move to the retreat position in a state where a torque of the electric motor is controlled below an upper limit value load, while limiting an actuation time of the electric motor.SELECTED DRAWING: Figure 1
【課題】ブローアウトパネルを移動させる際に電動機が過負荷にならないようにする。【解決手段】強制開放システム１００は、建屋（原子炉建屋１１）の開口部１３に設置されたブローアウトパネル１６と、建屋の外壁１２に沿って移動する遮蔽体（遮蔽扉１４）と、遮蔽体の閉止時の閉止位置よりも外側の退避位置にブローアウトパネルを移動させる強制開放機構２０と、ブローアウトパネルが閉止位置よりも外部に移動したことを検出する検出部（巻取り端リミットスイッチ５２ｂ）と、強制開放機構の電動機（電動ウインチ２１）の動作を制御する制御部５０と、を備える。制御部は、電動機の作動時間を制限しながら、電動機のトルクを上限値荷重以下に制御した状態で、退避位置にブローアウトパネルを移動させる。【選択図】図１
