Abstract
For studying the compatibility of vegetable insulating oil with insulating paper materials of transformer,9 different types of insulating paper materials commonly used in transformers are combined with vegetable insulating oil to study the performance variation of vegetable insulating oil and insulating paper after 164 h of aging.The perfor-mance difference of the insulation paper and insulating oil before and after the thermal aging experiment is observed,and the movement viscosity,moisture content,acidity value,dielectric loss factor,breakdown voltage of the oil paper combination as well as gas chromatographic analysis of the oil are tested.The results show that the movement viscosi-ty of the vegetable insulating oil has changed to some extent after aging,but the the structural integrity and functional stability remain good.Moreover,the vegetable-based insulating oil is highly compatible with 22HCC Dennison insula-tion paper.Compared to other test group,the compatibility of the electrical insulating paper and vegetable insulating oil is weak.After the thermal aging,the breakdown voltage of the metallized crepe paper,laminated paper board and the vegetable insulating oil is lower and the their compatibility is weak.These findings provide a basis for selecting in-sulation materials with good compatibility and optimizing insulation structures to ensure the safe and stable operation of vegetable-based insulating oil transformers.Furthermore,the study results help promote and apply vegetable insu-lating oil and promote the development of sustainable energy.关键词
