摘要
变压器过热故障是常见的多发性故障,变压器过热对变压器的安全运行和使用寿命带来严重威胁。因此,分析、判断和预防变压器过热故障已成为变压器运行和维护部门十分关注的问题。随着现代试验方式的不断发展,许多新的试验项目的出现,变压器的预防性试验已经越来越完善。分析了几种常用试验对变压器绕组发热故障检查的应用及效果。
Overheat is a familiar fault in transformer, it will bring serious threaten to safe operation and service life of transformer. Therefore how to analyze, judge and prevent overheat fault of transformer already become a problem that transformer operation and maintain department put attention to very much. Along with modem test manner develop continuously, the appearances of a lot of new test item, the transformer preventative test has been already completed more and more. The application and effect of using several normal tests to check transformer winding heat fault are studied emphatically.
