摘　　要：为了研究超特高压输电线路的交流电晕特性及其电磁环境,有必要获得不同型式多分裂导线的电晕特性参数。笔者介绍了基于特高压电晕笼的电晕效应试验方法和原理,深入分析和处理相关数据得到导线的可听噪声功率密度和无线电干扰激发函数,经过与已有的国外电晕特性经验公式曲线进行比较,证明了试验数据的有效性,并通过大量导线在不同天气、不同子导线半径、不同分裂间距下交流电晕特性数据,分析了导线交流电晕特性在不同因素影响下的特性,进而保证超特高压输电工程的经济性、节能性、环保性。In order to study AC line corona characteristics and electromagnetic environment of ultra-high voltage （UHV） transmission lines, it is necessary to obtain the corona characteristic parameters of different types of multi-split wire. The authors introduced the test methods and principles of corona effects based on ultra-high-voltage cage, analyzed and processed the relative data to get wire＇s audible noise power density and radio interference excitation function, and compared the data with the existing foreign from corona characteristics empirical formula to prove the validity of the test data. Moreover, the AC corona characteristics were analyzed with different influencing factors such as different weather, different sub-wire radius, different spacing distance, etc. to ensure the economy, energy saving, and environmental protection for uhra-high voltage transmission engineering.
