摘　　要：文章整理和分析了中国电力科学研究院与云南电力试验研究所有关换流站阀厅内典型屏蔽环和母线的可见电晕试验数据,讨论了不同海拔高度下起始电晕电压的校正方法(如不同海拔高度直流设备起晕电压校正方法和高海拔直流设备屏蔽环及母线起晕电压的海拔校正方法),认为目前低海拔换流站阀厅使用的电气设备的电晕性能可以满足海拔2000m使用的要求。The paper analyzed the visible corona test data owned by China Electric Power Research Institute and Yunnan Electric Power Testing and Research Institute about the typical shielded ring and bus in valve hall in converter station, discussed the correction methods of initial corona voltage in different altitude above sea level (such as the correction methods of initial corona voltage in different altitude above sea level for DC equipment and the correction method of initial corona voltage of high elevation for shielded ring and bus of high elevation DC equipment). The conclusion is that the corona characteristics of the electrical equipment used in valve hall in converter station in lower elevation now can satisfy the requirements of the use in 2000 m altitude above sea level.
