摘　　要：本文作者对一台63MVA/110kV的变压器成品试验中本体介质损耗超标问题的排查处理,发现是由于铁心柱中层压木圆撑棒本身质量状态引起的,而并非变压器器身干燥不彻底或器身受潮所致,为实际变压器生产中的介质损耗超标的分析和处理提供了一个新的思路和方向。In this paper,through the troubleshooting process of the excessive dielectric loss of the main body in the finished product test of a 63MVA/110kV transformer,the author finally confirms that it is caused by the quality status of the laminated wood round support rod in the middle layer of the iron core column,rather than incomplete drying or dampness of the transformer body.This provides a new idea and direction for the analysis and treatment of excessive dielectric loss in actual transformer production.

关 键 词：变压器 介损超标 层压木圆撑棒
