摘　　要：载流量是电力电缆运行的重要指标,其计算模型的准确性对电缆精益化管理和电网安全稳定运行具有重要意义。文章在某电缆敷设通道局部发生变化后,按照实际敷设条件,对电缆不同排列间距进行载流量计算分析,得出限制电缆载流量的主要因数,提出相应的注意事项,避免设计失误。The current carrying capacity is an important indicator for the operation of power cables,and the accuracy of its calculation model is of great significance for the lean management of cables and the safe and stable operation of the power grid.After a local change occurred in a certain cable laying channel,the article analyzed and calculated the current carrying capacity of cables with different arrangement spacing based on actual laying conditions,identified the main factors limiting the current carrying capacity of cables,and proposed corresponding precautions to avoid design errors.
