汽轮机调速系统负荷骤甩的分析研究

Cause Analysis of the Sudden Load Fling off of the Steam Turbine'a Governing Systems

针对调速系统负荷骤甩的故障现象,通过试验的方法,分析出了由于微分器滑阀卡涩,导致调速系统误动作的原因,找出了处理问题的方法,并在检修过程中实施,取得了良好的效果。

By taking into consideration the sudden load fling off of the governing system and through a series of tests, the authors found that it was the blocking of the differential speed sensor＇s sliding valve that resulted in the misoperation of the governing system. Then the solution was decided and used in the process of maintenance, and the results were rather good.
