基于非均匀排布的双回电缆线路温度分布特性研究
Research on Temperature Distribution Based on Nonuniform Arrangement of Double-circuit Cable
摘要
Abstract
The temperature distribution has a significant effect on the comprehensive life of power cables.This paper studies the temperature distribution characteristics of YJLW03-64/110kV-400mm2 and YJLW03-64/110 kV-630 mm2 cable schemes.Firstly,the coupling model of electromagnetic field and temperature field of cable is established by ANSYS;and the temperature distribution law of equal-spacing equal-section cable is analyzed.Furthermore,the distribution law of cable temperature distribution with equal spacing and unequal spacing under unequal load and different cross-section conditions is analyzed and compared.The results show that the maximum temperature rise of the cable is obviously lower than that of the uniform arrangement when the cable is unevenly distributed.In this example,the maximum temperature of the cable is reduced from 55.6℃ to 54.3℃;the reduction ratio is 4.2%.Nonuniform arrangement of the cable temperature distribution under the optimization of the design and selection of cable lines has a certain significance.关键词
