色谱分析在变压器维护上的应用和分析方法

摘要

With high sensitivity and unaffected by environmental conditions chromatogra-phy is an effective method for monitoring the function of a transformer without the need of power cut off. Chromatography has already been widely applied in transformer substations at Jinan Steel. Causes of gas forming inside transformer, the principle of chromatography and judgment method for related troubles are introduced and briefly analyzed.%　　色谱分析是监测运行变压器性能的一项有效措施，它在监测时不需要将设备强制停电，而且灵敏度又高，而且不受外界环境及因素的制约。色谱分析在济钢各个变电站得到了广泛的应用。针对变压器内部的产气原因及色谱分析的原理及方法以及相应故障的类别判定方法，进行了分析与介绍。
