摘　　要：针对目前直流系统电缆截面选择存在依赖人工手段、调整参数之后需反复核对、计算繁琐等问题,笔者结合电缆截面选择原则,采用编程软件开发直流系统智能设计工具,通过直流负荷配置、电缆参数设置及选择、电缆电压降校验实现自动计算,并以树状图的形式展现直流系统电缆截面选择和电压降分配结果,提高了计算效率和准确度,可为直流电缆选择提供借鉴。In response to the curent problems of relying on manual methods,requiring repeated verification after adjusting parameters,and cumbersome calculations in the selection of cable sections in DC systems,the authors combine the principle of cable section selection and use programming software to develop an intelligent design tool for DC systems.Through DC load configuration,cable parameter setting and selection,and cable voltage drop verification,automatic calculation is achieved.The results of cable section selection and voltage drop distribution in DC systems are presented in the form of a tree diagram,which improves calculation efficiency and accuracy,and can provide reference for DC cable selection.
