化工企业低压电动机配电电缆截面选择及校验

Selection and calibration of low voltage motor distribution cable section in chemical enterprise

以某化工企业工程为例,总结了选择低压电动机动力电缆和两种控制回路的截面选择,并以项目中以距离配电室最远电机为例,对电缆截面选择进行计算并校验,为电气设计人员在以后项目中的选择截面提供参考。

Taking an engineering project of a chemical enterprise as an example,this paper summarizes the selection of power cable of Low-voltage motor and the selection of cable section of two control loops. Taking the motor that the farthest from the distribution room as an example, cable section is calculated and verified to provide reference for electrical designers in the selection of cable section in the future projects.
