不同材料的隧道电缆支架适用性对比研究

open access: yesGaoya dianqi
输电电缆线路运行电流较大,电缆支架涡流损耗和温升的问题被广泛关注,急需寻找一种损耗小、温升低、经济性能良好的支架材料。文中采用多物理场耦合的有限元分步仿真计算方法对220 kV电缆线路的钢、不锈钢和新型玄武岩复合材料支架的涡流损耗和温升进行计算。首先在频域下计算涡流损耗,之后再以涡流损耗作为热源,在瞬态下进行电磁场—温度场—流体场三场耦合计算,从而计算出支架温度分布。该方法在保证计算精度的前提下极大降低了计算的复杂度。计算结果表明:钢支架涡流损耗远大于不锈钢支架和玄武岩支架的涡流损耗。电缆电流为1 ...
