摘　　要：换流站内冷水系统电导率仪投运后未校验,无法及时掌握表计及水质真实情况,现场进行比对试验,但测量数据误差较大,分析认为空气是影响比对试验数据的主要因素。通过改进比对试验,即使水样通过一密闭检测池,在流动状态下测量密闭检测池中的内冷水水样,减少空气对试验结果的影响,准确测量内冷水水质,确保了换流站换流阀安全稳定运行。The conductivity meter of the water cooling system in a convertor station was not verified after being put into operation,so the real condition of the meter and the cooling water quality cannot be known well. And the field comparison test has a bigger measurement error. The analysis on the field comparison test concludes that the atmosphere is an important factor influencing the test data. And that an improvement on the comparison test was made that reduces the effect of the atmosphere to the test result by measuring the cooling water sample flowing through a closed test pool and then accurately measuring the cooling water quality.
