摘要
通过介绍油纸电容式变压器套管的构造,分析其内绝缘常见的故障,进而提出了变压器套管及末屏tanδ测试的必要性,并提出了用tanδ值判断绝缘的标准,提出了合理的套管tanδ的测试方法和测试时应注意的事项。
Pass the introduction oil immersed paper electric capacity type transformer set the structure of the bushing,analyze it inside insulate familiar breakdown,explain to carry on the meaning of the tanδtest that a set of tube and end hold.Analyzed the tanδa test principle in brief,put forward the transformer set the tube and end to hold the necessity of the tanδtest thus,and standard put forward insulating with the tanδvalue judgment,put forward reasonable of the set take care of the test method and test of the tanδshould notice of item,summary's appearing a field should value the tanδto test this problem.
