| 中文摘要 | 为了研究复合绝缘子沿面电晕放电状况,以110kV复合绝缘子为试验对象,利用一种基于光电倍增管的紫外电晕检测装置来测量绝缘子电晕产生的紫外光,探讨复合绝缘子沿面电晕放电发展和分布特征。通过逐步升高施加电压的试验方法,检测得到复合绝缘子在不同表面条件下(干燥、清洁、潮湿、染污)沿面电晕放电发展和分布状况的脉冲量化特征数据。测量结果表明:当电压升高时,表面干燥条件下的复合绝缘子电晕放电沿串长发展和分布,而表面潮湿条件下的复合绝缘子电晕放电随机性较大。电晕紫外光脉冲个数以及脉冲平均峰值可以用作检测电晕放电的特征参数,以判定复合绝缘子电晕放电状态。; A novel ultraviolet corona discharge detection system using photomultiplier to measure ultraviolet light was applied to study the corona discharge performance along the surface of 110 kV composite insulators.When voltage applied on composite insulator was increased gradually,development status of composite insulators' surface corona discharge under different conditions(dry,clean,wet,polluted) was measured,and the corona discharge characteristics data,number and mean peak values of ultraviolet corona pulses under different applied voltages and surface conditions,were obtained.The results show that corona discharge on the dry surface of composite insulator develops along insulator from high voltage end to the ground,but the corona discharge developing status is random along insulator when the surface is under polluted and wet conditions,and that number and mean peak values of ultraviolet corona pulses can be used to quantify the detection of corona discharge and learn about the corona discharge status of composite insulators.; 国家自然科学基金(90210030)~~ |
