摘要
介绍了超高压强制循环式变压器所用变压器油的油流带静电现况。主要研究变压器油烃组成对油流带静电倾向的影响,考察了不同芳烃含量的环烷基变压器油油流带静电倾向,相同芳烃含量不同原油类型变压器油的油流带静电倾向,变压器油的硫、氮化合物对变压器油的油流带静电倾向的影响。同时,研究了不同环数的稠环芳烃对变压器油油流带静电倾向的影响。从研究结果中发现,高稠环芳烃含量会增加变压器油油流带静电倾向。
The results of studies on the electrostatic charging tendency（ECT） of flowing transformer oils for OF-or OD-cooled super high voltage transformers were summarized.The influence of hydrocarbon compositions of transformer oils on the ECT was studied in detail,in which the ECT of naphthenic transformer oils with different aromatic hydrocarbons content,and the ECT of different crude oil style transformer oils with the same aromatic hydrocarbons content were mostly investigated.The influences of the sulphide compounds,the nitride compounds,as well as poly-aromatics content on the ECT were also studied.It was found that high poly-aromatics content in transformer oils should increase the ECT of transformer oils.
