Abstract
The mode of laying power cable in pipes was designed to allow additional cable circuits to meet the future load increase.For different positions of original and additional cables,the temperature field and ampacity are different.It is,therefore,necessary to optimize the positions of original cables and additional ones.A finite element model is built in this paper by taking the 3 ×4 pipes for laying distribution cables as an example,and the validity of the model is verified by comparing the results of temperature-rise experiments and that of simulation.Based on the model,the positions of the original 6-circuit and 1 additional circuit are optimized based on the lowest conductor temperature of the most serious heating cable under the condition of same ampactiy for all circuits.The simulation result shows that the more scattered the cables are,the more uniform the temperature field is,and the lower the conductor temperature of the most serious heating cable.The optimal position of the additional cable is related to the position of original cables.Therefore,it is suggested that the future additional cables should be taking into account when optimizing the original position of cables.关键词
