摘　　要：气垫式调压室是用于控制水电站水力过渡过程的新型调压室，具有布置灵活、适应水位变幅大和电站负荷变化后调压室水位波动小的优点，国外已应用于控制水电站引水系统和火电站供水系统水力过渡过程。本文介绍了气垫式调压室的工作原理、参数选择及涌波计算方法。Air cushion surge chamber is a new type surge chamber which has been used to control hydraulic transient in hydropower station. It is characterized by easy arrangement,large amplitude of fluetuation for water level and small undulation of water level in surge chamber after load changes in hydropower station. The air cushion surge chamber has been used to control hydraulic transient in a diversion system of hydropower station and a water supply system of thermal power plant. The operation principle,parameter choice and surge calculation method for air cushion surge chamber are presented in this paper.
