摘　　要：导线表面电场强度取决于运行电压、子导线直径、分裂数、分裂间距、导线高度以及相间距离等。对±500kV直流线路导线表面电场强度进行计算，结果显示，导线表面电场强度受导线分裂根数、子导线直径的影响较大，导线高度和导线分裂间距影响较小。The surface field strength of a conductor depends on the running voltage, the diameter of sub-conductor, the number of bundled conductor, bundled wire pitch, The height of conductor, phase- to-phase distance, etc. The surface field strength of the conductor used in a ± 500kV HVDC Transmission Line is calculated. The result shows that the field strength is affected more by the number of bundled conductor and the diameter of sub-conductor and less by the height of the conductor and the bundled wire pitch.
