摘　　要：淮安二站作为南水北调第二梯级主力泵站,针对其原有机组测温系统运行中出现的温度无显示、实时温度不更新、读取测温偏差大等问题,经过研究分析,对其测温系统进行更新改造。通过更换新款设施设备并选取隔爆型热电阻,增加检测端安全型隔离栅,提高机组运行时温度监测的可靠性、稳定性、准确性,保障了工程运行安全,充分发挥了设计效益。As the main pumping station of the second cascade of the South to North Water Diversion Project,the original unit temperature measurement system of Huai’an Second Station often malfunctioned,resulting in three types of problems during operation:no temperature display,no real-time temperature update,and large reading temperature deviation.the temperature measurement system was updated and transformed.According to replacing new facilities and equipment,selecting explosion-proof thermal resistors,and adding safety isolation barriers at the detection end,the reliability,stability,and accuracy of temperature monitoring during unit operation have been improved,which ensured the safety of engineering operation and fully exerted design benefits.
