摘　　要：基于浙北—福州1000 kV特高压交流线路现场测试结果,研究了特高压交流线路金具的常见电晕问题。借鉴中国1000 kV特高压交流输电线路金具设计、制造、建设及运行经验,根据1000 kV特高压交流线路技术参数开展了悬垂串、耐张串和跳线串均压屏蔽环金具结构的优化设计工作,通过悬垂串的真型电晕及噪声测试进一步验证了金具的优化效果。The common corona problems of fittings for ultra high voltage alternating current transmission lines are analyzed based on the field test results of the Zhebei-Fuzhou 1000 kV UHV AC transmission line.According to the technical parameters of 1000 kV UHV AC transmission lines,structure design optimization is carried out for fittings such as suspension string,tension string,the grading and shielding ring of rigid jumper string based on the design,manufacture,construction and operation experience of 1000 kV UHV AC transmission line fittings in China.The optimization effect of the fittings is further verified through the full scale test of corona and noise of the suspension strings.
