中文摘要	为深入研究高海拔地区导线电晕无线电干扰问题,以满足我国高海拔输电线路工程需要,利用可移动式电晕笼在4个不同海拔地区开展了多种导线交流电晕无线电干扰试验研究,并对试验结果进行了细致分析,得到了导线表面场强对无线电干扰海拔修正的影响和海拔高度对无线电干扰的影响特性。如果按线性关系修正,所得到的无线电干扰海拔修正系数为3.13dB/1000m,与国外海拔修正系数3.3dB/1000m比较一致。然而,经分析发现,海拔高度和导线交流电晕无线电干扰之间不呈线性关系,海拔越高,海拔高度的变化对无线电干扰的影响越小。通过分析测试结果提出了粗略的海拔修正量与海拔高度的非线性修正关系,并给出了不同海拔高度对应的无线电干扰海拔修正量。最后,推荐了一种适于海拔>3000m地区的高海拔输电线路无线电干扰海拔修正方法,以供我国高海拔实际工程借鉴。; As an important index of electromagnetic environment, radio interference due to corona is much higher in high altitude area than on ground. For proper conductor selection, it is necessary to study the corona effect of conductor in high altitude area. Thereby, a mobile corona test cage was applied to research the influence of altitude changes on AC corona radio interference of conductor. The effects of conductor surface gradients and altitude on radio interference were analyzed in detail. Based on linear correction relation, a correction coefficient of 3.13 dB/1000 m was obtained which was well in agreement with the foreign coefficient 3.3 dB/1000 m. The test results show that AC corona radio interference of conductor is nonlinearly varied with altitude. The higher the altitude is, the smaller the effect of altitude changes on AC corona radio interference will be. An emprical expression between altitude correction coefficients with the altitudes is presented. Finally, an altitude correction method of RI is put forward.; 国家“十一五”科技支撑计划(2006BAA02A19;2006BAA02A20;2006BAA02A04); 国家自然科学基金(50777035)~~
