随着水电站单机容量越来越大,水轮发电机组的安全稳定运行显得越来越重要,机组运行温度是水轮发电机组安全运行的一项重要指标,因此监测运行温度非常必要。就监测水轮发电机组运行温度的元件RTD,从两个方面进行探讨,一是从RTD使用技术条件进行分析和总结,提出了技术要求和建议；二是对国内几大水电站RTD在使用过程中出现的故障进行分析和归类,剖析其故障原因,提出了相应的处理措施和预防手段。综合两方面的分析和总结,对RTD的使用和技术发展提出建议。
隨著水電站單機容量越來越大,水輪髮電機組的安全穩定運行顯得越來越重要,機組運行溫度是水輪髮電機組安全運行的一項重要指標,因此鑑測運行溫度非常必要。就鑑測水輪髮電機組運行溫度的元件RTD,從兩箇方麵進行探討,一是從RTD使用技術條件進行分析和總結,提齣瞭技術要求和建議；二是對國內幾大水電站RTD在使用過程中齣現的故障進行分析和歸類,剖析其故障原因,提齣瞭相應的處理措施和預防手段。綜閤兩方麵的分析和總結,對RTD的使用和技術髮展提齣建議。

The safe and stable operation of the hydro-generating units becomes more and more important with the larger ca-pacity unit of hydropower stations are applied. It is necessary to monitor the operating temperature that is an important indicator of hydro-generating units. In this paper, application of RTD in temperature measuring of generating units is discussed in two as-pects. The technical requirements of RTD are analyzed and summarized to propose technical specifications and recommendations;the failures of RTD in several large hydropower stations are analyzed and classified to discover the causes of failure, and then the rational preventive measures are put forward. The suggestions on technical requirements and development of RTD are given on the basis of the above analysis and conclusion.
