摘要
国内500 kV同塔四回输电线路将是国际上首次应用。介绍了几种塔型结构、相序布置在不同系统运行方式下的线路工频过电压、潜供电流和恢复电压的研究情况,分析了塔型和相序变化对工频过电压和潜供电流的影响,并提出了结论和建议。
The 500 kV four-circuit lines on the same power to be built in China is the first one in the world. The power frequency over-voltage, the secondary arc current, and the recovery voltage of the lines with different tower types and various phase order arrangement are studied under different system operational modes. The influences of tower types and phase orders on the power frequency over-voltage and the secondary arc current axe analyzed, and conclusions and suggestions are proposed.
