摘　　要：对变电所两台120000kVA变压器绝缘油介损的增大进行了理论分析，并得出变压器绝缘油浸入溶胶杂质或微生物感染是介损增大的原因、用真空滤油机或压力滤油机进行处理不会使介损降低、处理绝缘油的设备所用的管路不能用橡胶管而应采用硬塑管或尼龙管。In accordance with authors increase of tgδ in two 12 000kVA transformers the authors give the analysis. It shows that tgδ will increase when the colloidal impurity is im-mersed into transformer oil or microorganism infects the oi1. It cannot reduce tgδ using vacum oil filter machine or pressure oil filter machine. Rubber tube can not be used in the oil trcatment equipment and plastic or nylon tube should be used instead.
