提高600MW发电机组轴系温度保护的可靠性

To improve the reliability of shaft temperature protection for 600MW generator

轴系温度保护系统作为汽轮发电机组最重要的保护之一,其稳定性、准确性直接影响整个汽轮发电机组的安全稳定运行。但由于现场存在各种干扰因素,严重影响了轴系温度保护系统的正常运行。如何保证轴系温度保护系统的稳定、准确运行,是我们热控检修人员必须解决的问题。本文着重从抗干扰方面来降低轴系温度保护系统的故障概率进行分析讨论。

The shaft temperature protection system as one of the most important protection of turbine-generator unit, its stability, accuracy directly affect the turbine-generator unit safe and stable operation. However, the existence of various interfering factors, the site has seriously affected the shaft temperature protection systems. How to ensure the shaft temperature protection system to function stable and accurate, is a promblome than maintainers must resolve. This article focuses on how to reduce the failure probability of the shaft temperature protection system from anti-disturbance.
