中文摘要: 以200 kV 800 mm2截面YJLW02型XLPE为例,研究了对流换热系数对载流量的具体影响.最后通过经验公式,计算出了较为准确的对流换热系数值,从而确定了较为准确的载流量.

中文关键词: 电缆温度场载流量对流传热系数

Abstract:The 220 kV YJLW02 XLPE with 800 mm² section is taken as an example,the heat transfer coefficient of convection and its impact on the ampacity are studied. Finally,a more accurate heat transfer coefficient of convection is calculated to determine a more accurate ampacity by empirical formula.

keywords: cable temperature field ampacity heat transfer coefficient of convection
