查询词典 wicket

From this formula we can explain the tendency that the hydrovibration frequency increased with decreasing wicket gate opening of Francis turbines.

此式可以解释水力振动频率随混流式水轮机导叶开度减小而增高的趋势，并用两个压力梯度方程初步阐述了压力脉动振幅随工况而变化的现象。

The governor is designed with model structure. Closed-loop start-up strategy is applied during running and it realizes three adjust mode-frequency, wicket gate and power.

调速器采用模块结构进行设计，在调节过程中实现了闭环开机控制策略，并可在频率调节、开度调节、功率调节三种调节模式之间自动或手动无扰动切换。

By the accident analysis,it is known there shall be a corresponding on-cam relationship between wicket gate opening limitation and requirement of spring force.

通过事故分析，提出对导叶开度限制及弹簧力要求并相应协联关系、主令控制器、监控控制都要设置得当，相应配合，否则易突发事故影响机组正常运行。

At present, most hydropower plants close the wicket gate by using the closing law with two or three slopes. In fact, as the unit capacity goes up and the turbine working range of water head be even wider than before, so that the fixed closing law with two or three slopes can't control the unit stability effectively when the big fluctuation transient comes op.

目前，普遍采用导叶两段或三段关闭规律，实践表明，随着水轮发电机组容量的增大和水轮机工作水头范围的增大，这种固定的两段或三段导叶关闭方式不能有效地控制机组在大波动水力过渡过程中的稳定性。
