摘要
简要介绍了国际电工委员会(IEC)于1995年颁布的“电力电缆尺寸的经济最佳化”计算方法,并以发电厂厂用电缆为例,对电缆截面进行了初步的分析计算,提出了做好电力电缆截面选择工作的对策和建议.
The computing method of ＂the Economical Optimization of the Size of Power Cables＂ promulgated by ＂the International Electrotechnical Commission＂ in 1995 is briefly introduced ; and examplified by the power cables used in the power plant, the cross section of the power cables are analyzed and computed. Finally, some counter-measures and suggestions on the selection of cross section of power cables are put forward.
