摘要

为了比较110 kV光滑铝护套电缆和波纹铝护套电缆的运行参数，采用等效热径分析法计算了两者的热阻、损耗系数和载流能力。结果表明:光滑铝护套电缆的热阻和损耗均小于波纹铝护套电缆，其承载能力为776.88 a，比波纹铝护套电缆的承载能力提高10.8%;这表明，与波纹铝护套电缆相比，光滑铝护套电缆具有更好的经济性和应用前景。

Comparison of the Current Carrying Capacity Between 110 kV Corrugated and Smooth Aluminum Sheathed Cables Based on Thermal Analysis

To compare the operating parameters of 110 kV smooth aluminum sheathed cables and corrugated aluminum sheathed cables, the thermal resistance, loss coefficient and current carrying capacity of the two are calculated by means of an equivalent thermal path analysis. The results show that the thermal resistance and losses of the smooth aluminum sheathed cable are less than those of the corrugated aluminum sheathed cable, which results in a load capacity of 776.88 A for the smooth aluminum sheathed cable, an increase of 10.8% compared to the load capacity of the corrugated aluminum sheathed cable. It is an indication that smooth aluminum sheathed cable has better economic and application prospects compared to corrugated aluminum sheathed cable.
