自1895年瑞士西尔水电站采用调压室以来,到目前为止,调压室是公认的减小水道中水击压力最为可靠的一种特殊建筑物。它之所以可靠,就在于在水电站运行过程中,它不需要任何人为的控制,而自动地应付着水轮机引用流量的变化。但是,它的结构复杂,施工条件较差,且造价较高,有时还会影响整个工程 Since the adoption of the surge chamber at the Swiss Cyr hydropower station in 1895, the surge chamber has so far been recognized as the most reliable type of special structure for reducing the water hammer pressure in a watercourse. The reason it is reliable is that it does not require any human control during the operation of a hydropower station, and it automatically copes with changes in turbine flow rates. However, its complex structure, poor construction conditions, and high cost sometimes affect the entire project
