提高变压器油色谱分析检测精度的几个问题

Some Problems on Improvement of Accuracy of Chromatograghy Analysis of Transformer Oil

气相色谱法检测变压器油工作中,取样、测试诊断过程、载气、进样垫的使用、进样与注射器等是常见的问题,正确解决上述问题,采取相应的对策及措施,在严格操作技术上使色谱分析的精确度和诊断变压器故障能力得到进一步提高.

In gas chromatograghy analysis of transformer oil, one usually meets some promblems in sampling and testing process, such as how to handle carrier gas, insert gasket, sample inserting and injector etc. These promblems can be solved by taking suitable measures accordingly and careful operations to perform the analysis. The accuracy and capability of diagnosis of potential transformer fault can be further improved thereby.
