摘　　要：绝缘油色谱检测对于发现变压器内部潜伏性故障有着至关重要的作用。在变压器故障中,氢气含量的变化较为敏感。变压器受潮、局部放电,火花放电、电弧放电时,氢气含量都会增长,另外绝缘材料、金属材料中析出氢气,绝缘漆、绝缘油种类等都会影响氢气含量变化。The insulating oil chromatographic detection plays a crucial role in finding the internal latent faults of the transformer.In many transformer faults,the change of hydrogen content is sensitive.Transformer damp,partial discharge fault,spark discharge,arc discharge fault,hydrogen content will change and increase,in addition,the separation of hydrogen in insulating materials,metal materials,insulating paint,insulating oil,etc.,will affect the change of hydrogen content.
