More Information
Summary:The present invention relates to a fire protection damper of a transformer room which is installed on an upper side of a transformer room to open/close an opening. The fire protection damper comprises: a pair of guide rails installed in parallel in a longitudinal direction along the opening at positions spaced apart from each other and having guide grooves formed in the longitudinal direction; and a foldable door unit made of a plurality of opening/closing panels associated and rotated by being connected through a hinge unit as a medium and disposed between the pair of guide rails, wherein the opening/closing panels move backward while being bent around the hinge unit to open the opening or the opening/closing panels move frontward while being unfolded around the hinge unit to close the opening. The plurality of opening/closing panels are connected to each other to prevent separation and dropping of the opening/closing panels due to damage. 본 발명은 변압기실의 방화용 댐퍼에 관한 것으로, 변압기실의 상측에 설치되어 개구부를 개폐하도록 설치되는 변압기실의 방화용 댐퍼에 있어서, 서로 일정간격 이격되는 위치에 개구부를 따라 길이방향으로 나란하게 설치되며 길이방향으로 형성된 가이드홈을 구비하는 한쌍의 가이드레일, 서로 힌지부를 매개로 연결되어 연동하여 회전하는 복수 개의 개폐패널로 구성되어 한쌍의 가이드레일 사이에 배치되며 개폐패널이 힌지부를 기준으로 접히면서 후방으로 이동하여 개구부를 개방하거나 개폐패널이 힌지부를 기준으로 펴지면서 전방으로 이동하여 개구부를 폐쇄하는 접이식 도어유닛을 포함하여 복수개의 개폐패널이 서로 연결되어 파손으로 인한 개폐패널의 탈락 및 추락을 방지한다.
