摘要
对大型自耦变压器热油循环过程中开展低频辅助加热进行了专门研究,计算了常用接线方式下的辅助加热功率及功率在绕组上的分布,给出了现场用建议接线方式,并利用开发的低频加热装置在现场开展热油循环的辅助加热工作,完成现场绝缘受潮变压器的绝缘处理,质量检测达到良好效果。
The hot oil circulation of transformer has the deficiency of low efficiency,long treatment duration.Especially under the low temperature in winter,hot oil circulation can not reached expected temperature for the restriction of equipment and technology.Taking 330kV autotransformer as study subject,in the treatment of hot oil circulation in winter,short-circuit method is used to conduct low frequency auxiliary heating,which has improved heat efficiency,shortened the treatment duration and reached the expected effect.
