带上室的阻抗式调压室是在常规的阻抗式调压室上部增设一扩大水池构成的调压室,兼有常规阻抗式调压室和水室式调压室的双重作用,所需的调压室高度比阻抗式小,结构又比双室式调压室简单。文章介绍了郑家湾水电站带上室的阻抗式调压室结构布置及涌波计算的方法。
The impedance surge chamber with the upper chamber is provided with a surge chamber formed by an enlarged pool in the upper part of the conventional surge chamber and has the dual functions of a conventional surge chamber and a surge chamber. The height of the surge chamber is smaller than the impedance and the structure is simpler than the two-chamber surge chamber. This paper introduces the structure of surge tank and the method of calculating the surge in the ballast chamber of Zhengjiawan Hydropower Station.
