YT型调速器是小型水电站常用的一种调速设备,它有3种运行方式:机械手动、油压手动和油压自动。它们三者之间可以相互切换,因此,使用起来非常方便灵活。 并网运行的一些小型水电站,在采用“油压自动”运行方式时,调速器经常处于一种不合理的状态,即“开限红针”与“开度黑针”重合在一起,“转速调整指针”在+5％至+7％。 YT-type governor is a commonly used speed control equipment for small hydropower stations, it has three kinds of operation: mechanical manual, hydraulic manual and hydraulic automatic. They can switch between the three, so it is very convenient and flexible to use. Some small-scale hydropower stations running on the grid, in the “hydraulic automatic” mode of operation, the governor is often in an unreasonable state, that is, “Red Limit Red” and “open black needle” coincide with the “ Speed ​​Adjustment Pointer ”at + 5% to + 7%.
