There is no clear design method and general requirements for the catenary at the air defense partition door in foreign countries. Some domestic projects adopt the design scheme of rigid suspension small anchor section or the scheme of disconnectable device. However, the design scheme of the small anchor section has the disadvantages of long disassembly and recovery time. When the civil air defense partition door is also used as the flood-proof door, it is difficult to meet the time requirements for quick disconnection and closing of the flood-proof door. The patent with the application number 201821099858.8 discloses a rigid catenary automatic disconnection and recovery device, which is composed of three parts: a sliding busbar joint, a movable busbar in the middle section, and an articulated busbar joint, wherein the sliding busbar joint and the hinged busbar are fixed respectively. On the fixed ends of the bus bars on both sides of the opening and closing track of the flood-proof door or the partition door, one end of the middle movable bus bar is fixed to the hinged bus bar joint through a hinge shaft. This disconnectable device scheme has a certain influence on the current quality of the pantograph due to the concentration of mass.
