摘要

为推动我国变压器油流动带电度测量技术的标准化

在实验室建立了一套微静电测量系统

制定了详细的测量规程

并对影响测量结果的关键因素(温度、流速、滤纸和油流次数)进行了试验研究和讨论.研究结果表明:变压器油流动带电度的测量值随温度(10～50 ℃)的升高显著增加

据此推导出带电度随温度变化的校正公式; 新油的带电度基本不受流速的影响

老化油的带电度随流速增长下降明显; 滤纸和油流次数同样是影响测量结果的重要因素.该研究对于推动我国变压器油流动带电度测量技术的标准化工作具有积极意义.

Abstract

To promote the standardization of streaming electrification measuring of transformer oil

a mini-static tester is developed in the laboratory

detailed measuring procedures are scheduled

and some key factors such as temperature

flow rate

filter paper and number of oil flow

which would influence the measurement results are discussed as well. The results indicate that electrostatic charging tendency(ECT)increases significantly with temperature(10～50 ℃)

then an emendation formula for ECT changing with temperature is obtained.The ECT of new oil is not influenced by flow rate while ECT of aged oil decreases obviously with the increasing flow rate

and the filter paper and number of oil flow also affect the measuring results.
