摘要:
 为研究温度对叠加电场作用下油纸绝缘油流带电特性的影响,在实验室搭建了平板电极结构的典型换流变压器油纸绝缘模型,利用密闭油循环系统进行了叠加电场下油流带电的试验研究,并建立了油纸绝缘油流带电模型对试验结果进行理论分析。试验结果表明: 温度对油纸绝缘冲流电流有较大的影响,随温度的升高冲流电流呈先增大后减小的趋势。理论分析表明: 在较低温度下冲流电流与纸中负离子迁移速度有关; 在较高温度下冲流电流大小不仅取决于纸中负离子迁移速度,同时还与接地电极处正离子泄放速度有关。温度通过影响绝缘纸电导率、变压器油电导率以及变压器油粘度而影响油流带电特性。
Abstract:
 In order to study the influence of temperature on flow electrification characteristics of oil-paperinsulation under the AC superimposed DC electric field,
an oil-paper tube model with the typical plane e-lectrode geometry was built in laboratory. Experiment on flow electrification under AC superimposed DCelectric field was carried out with the closed oil circulating system,and the oil flow electrification modelof oil-paper insulation was built in order to analyze the experiment results. The experiment results showthat the temperature has a great effect on oil flow electrification of oil-paper insulation,and the current in-creases and then decreases with the increase of temperature. The theoretical analysis demonstrates thatthe streaming current depends on migration rate of the negative ion in paper at low temperature. Howev-er,t high temperature,it not only depends on the migration rate of the negative ion in paper,but also isrelated to the positive ion leakage rate at the grounding electrode. The temperature influences the flow e-lectrification characteristics by affecting the conductivity of insulation paper,the conductivity of transform-er oil,and the viscosity of transformer oil.
