地下电力电缆群敷设水冷管道模型的研究
Research on Water-cooled Pipe Model of Underground Power Cable Groups
摘要
Abstract
With the increasing of power load in the city,it is important to take appropriate measures to improve the carrying capacity of cable group.In this paper,we mainly explore this method of cable water-cooled pipe laying for capacity increasing.For water-cooled model,the heat generated by power cable groups is taken away by the convective heat transfer in water-cooled pipe,so that the environment temperature of cable groups decreases,therefore,it is a feasible and effective method to exploring cable transmission capacity of cable group.The theoretical models of underground power cable groups with water-cooled pipe is established,then the flow factors of aqueous fluid in watercooled pipe analyzed by using FEM,and ampacity for cable groups are calculated,thus the accuracy of the models is verified through experiments and the comparison with previous research results.These result of calculation on cable groups ampacity by Ansys indicate that water temperature and velocity have a great impact on cooling effect,and it can improves the heat dissipation effect of the cable groups,thus the total ampacity of cable groups is significantly improved to almost 28% for aqueous fluid in water-cooled pipe.关键词
