摘要
根据IEC相关标准,对低压电动机在额定运行工况与启动工况下分别进行了计算举例,并给出电动机电缆选择的详细步骤。通过电缆截面的计算可以使工程项目更准确地选择低压电缆。
According to the IEC standard,examples of calculations are given for low-voltage motors under rated operating conditions and starting conditions,and detailed steps are given for the selection of motor cables.In fact,the calculation of cable cross-section should be coordinated with the relay protection of the distribution circuit,which is not considered in this paper for the time being.
