摘　　要：针对芭蕉河电厂单活塞制动器在使用过程中存在的问题和缺陷,提出了改造为双活塞的解决方案。双活塞风闸制动器具有角度自调式功能,可确保制动力的有效传递;增大制动器的缸径及活塞尺寸,提高了制动力及系统的整体可靠性;采用液压系统及气系统分开设计,使制动响应更为迅速,可确保安全性和稳定性。制动器的改造解决了机组在停机完成后制动器长期复归不到位,信号反馈不准确及机组不能再次自动开机等一系列安全隐患,为安全生产和经济效益提供了有力保障。Considering the problems and defects in the usage of the single-piston air brake in Bajiaohe Hydropower Plant,a renovation scheme is proposed to change it to a double-piston type.The double-piston air brake has an angle self-adjusting ability,which ensures the effective transmission of the braking force.The cylinder diameter and piston size of the brake are increased to enhance the braking force and improve the overall reliability of the system.The separate design of the hydraulic system and the pneumatic system makes the braking response faster and ensures the safety and stability.With the renovation of the brake,a series of safety hazards of the units are successfully solved,such as the brake not returning to its proper position for a long time after the unit shutdown,inaccurate signal feedback,and the inability of the units to automatically start-up again,which provides strong guarantees for the safe production and economic benefits.
