摘　　要：直流融冰装置是架空导线覆冰最有效的除冰设备,能有效提高电网抵御冰冻灾害的能力。对直流融冰装置理论和应用的若干问题进行了探讨,包括其控制功能、保护功能、带线路融冰模式、开路试验模式、零功率试验模式、有功与无功消耗特性、交直流侧谐波特性、线路谐振过电压等,为直流融冰装置在实际电网的推广应用提供参考。The DC de-icer is an effective device to melt ice on overhead lines and can well improve the ability of power grid resisting frozen disaster. This paper does investigation on several issues in theory and application of the DC de-icer, including its control and protection functions, de-icing mode with AC lines, open line test mode, zero power test mode, active and reactive power characteristics, harmonic characteristics, and AC line resonance over-voltage as to provide reference for the DC de-icer applying to actual grids.
