摘要
热电偶温度计是发电厂主汽管道上测量温度的常用装置，如果温度计套管本身或安装工艺存在问题，都会发生套管漏泄问题，影响安全经济发电。该文分析了温度计套管漏泄的常见原因，提出了改进方法和处理措施，并进行了理论上的计算和论证。
Abstract Thermocouples are often used in powerplant pipes for temperature measurements of fresh steam. If the temperature measuring sheathes per se or their mounting are at fault, leakage may occur, impacting the safely of power generation. The paper discusses often met cases of leakage of sheathes, suggests remedies and ways of improvement.
