摘　　要：针对目前多根单相电缆流过大电流造成电缆支架发热问题,通过有限元静态磁场建模仿真,对不同排列方式下电缆磁场强度值进行一阶拟合分析,并提出单相电缆敷设时应根据不同类型的电缆支架选择敷设方式,指导项目施工现场完成单相电缆敷设,解决电缆支架的发热问题。With regard to the current problem of heating of cable supports caused by high currents flowing through multiple single-phase cables,finite element static magnetic field modeling and simulation are applied to perform first-order fitting analysis on the magnetic field strength values of cables under different layout.And it is proposed that the mode of layout for single-phase cables shall be selected in accordance with the different types of cable brackets for laying of single-phase cables.It is necessary to provide instructions on accomplishing of single-phase cable laying at site and solve the problem of heating of cable brackets.
