摘　　要：通过对各种防冰害技术进行综合比较分析,提出一种变电站设备除冰的适用技术,即热力带电除冰技术。针对包括热风除冰法、热水除冰法、辐射加热除冰法在内的3种热力除冰方法,建立工程计算模型。从理论上分析各种方法的除冰效率和能耗,并将理论计算结果与试验结果进行比较分析,同时对现场带电作业的安全性进行了理论分析和试验验证,得出的相关结论可为热力带电除冰技术的实际应用提供技术指导。Based on a comparative analysis of various conventional deicing methods, a new method, i.e., the thermal live deicing method, that is suitable for substation equipment, is developed. An engineering calculation model is established respectively for three thermal deicing methods, including the hot wind-based deicing method, the hot water-based deicing method and the radiation heat-based deicing method. The deicing efficiency and power consumption of the above-mentioned three methods are analyzed both in theory and test, and the security of living working in the field is verified through theoretical analysis and test validation. The obtained results can provide technical support for practical implementation of the proposed deicing method for living equipment.
