摘　　要：本文介绍了采用“过滤式”带电度测试装置对国产变压器油的带电度及有关静电带电性能进行试验研究的结果，分析了变压器油流带电过程及静电放电特点。此外，初步试验研究苯并三唑（ＢＴＡ）对油中静电的抑制作用及其影响。在此基础上，探讨了检测变压器中油流静电的试验方法。Recent investigation in static electrification properties of transformer oil is presented in this paper. A preliminary study on the effect of benzotriazole (BTA) used as a charge suppressant additive on the properties of the oil is carried out. Furthemore, the mechanism of static electrification and subsequent partial discharges in transformer is discussed. Based on the above mentioned work and analysis, the authors propose a test method for evaluating the static charging tendency of transformer.
