摘　　要：电晕的危害在于电能损耗的加大和电磁干扰。如果不对输电导线的电晕放电进行控制,所带来的资源浪费、经济损失和对通信的干扰影响较大,并且加大了电能传输过程中的碳排放。本文在高压输电导线等值电路的基础上,分析产生损耗的原因;在导线材料、导线型号、布置方式、导线分裂数和电压等级相关因素确定的前提下,工程实践对超高压输电导线电晕的控制主要就在于对导线表面粗糙度的控制;并提出了高海拔区域超高压输电导线电晕质量的控制原理和实现方法。The harm of corona lies in the increase of electrical energy loss and electromagnetic interference.If the corona discharge of the transmission line is not controlled,it will result in significant resource waste,economic losses,and interference with communication,and increase carbon emissions during the power transmission process.This article analyzes the causes of losses based on the equivalent circuit of high-voltage transmission lines.Under the premise of determining the factors related to wire material,wire model,arrangement method,wire splitting number,and voltage level,the control of corona on ultra-high voltage transmission wires in engineering practice mainly lies in the control of wire surface roughness.And the control principle and implementation method for the corona quality of ultra-high voltage transmission lines in high-altitude areas are proposed.
