摘　　要：港口大型起重用电设备种类较多,如集装箱轨道式门机、多用途门机、卸船机、装船机等。港口供配电设计首要是计算港机设备的运行电流,作为选用配电开关、配电电缆规格的依据之一,但目前计算结果差别较大,究其原因是计算方法多种多样。结合几种常见的计算方法进行对比,分析总结港口大型设备的运行电流的计算思路,供同类项目参考。There are many kinds of large crane electrical equipment in ports,such as container rail gantry,multi-purpose gantry,ship unloader,and loading machine.The primary purpose of port power supply and distribution design is to calculate the running current of port crane equipment,which is one of the bases for selecting distribution switch and cable specifications.However,the calculation results are quite different at present,and the reason is that there are various calculation methods.This paper compares several common calculation methods,analyzes and summarizes the calculation ideas of port large equipment running current,for colleagues reference.
