| 摘 要： | 我国第一条750 kV输电线路经过地区海拔高度基本在2 000 m以上，与国外已经运行的750 kV输电工程的运行环境有较大差异。在其线路设计中，导线的电晕特性对导线的选型有重大意义。用分裂导线控制导线表面的电场强度，可以避免大量的电晕损失。通过导线起晕电压试验，研究了导线表面场强计算，获得了高海拔地区750 kV输电工程设计基本参数，其研究成果推动和支撑了西北750 kV输变电工程建设。

| Abstract: | The altitude of the area where the first 750 kV transmission line in china crosses though is above 2 000 m. The operational condition of this project is difference from the condition of 750 kV power systems abroad. In the designing of this transmission line, the corona characteristics have a great effect on selecting of conductors. The using of bundles of conductors can reduce the strength of electric field on the surface of conductors and the power loss of corona. We researched on the experiments on discharge inception voltage, the figure of electric field on the surface of conductors, and acquire basic designing parameter of 750 kV power systems in high altitude localities. The achievements advanced the project of 750 kV power systems in northwest. |
