摘要
针对汽轮机组TSI系统超速保护信号异常波动问题,通过整合机组检修项目经验,进行转速异常现象分析。根据超速保护模块的逻辑构成,进行故障原因排查,确认由超速保护卡件发出报警信号,并采取重新插接通信线、优化卡件通信参数配置等技术措施,消除超速保护信号异常现象,为同类设备检修提供重要参考。
Aiming at the problem of abnormal fluctuation of overspeed protection signal of TSI system of steam turbine unit,the analysis of abnormal rotational speed is carried out by integrating the experience of unit overhaul project.According to the logical composition of the overspeed protection module,the cause of the fault is investigated,the alarm signal is confirmed to be issued by the overspeed protection card,and technical measures such as re-plugging the communication line and optimising the configuration of communication parameters of the card are taken to eliminate the anomalous phenomenon of the overspeed protection signal,which provides an important reference for the overhaul of the same kind of equipment.
