一个75千瓦的电机启动电流是多大？正常使用的电流又是

Jul 23, 2016 380V情况下75kw 额定电流约为15A，启动电流是额定电流的47倍，正常使用时空载电流约为额定电流的3050%。空载电流约为额定电流的30～50%。在工程实 Jun 1, 2020 电机启动电流到底有多大？电机的启动电流是额定电流的多少倍说法不一，很多都是根据具体情况来说的。如说十几倍的、6~8倍的、5~8倍的、5~7倍的等。一种是电机启动电流到底有多大?6~8倍、5~8倍、5~7倍？知乎

实测75KW电机启动电流90A，配20A电闸，为什么不会跳

Mar 20, 2022 ④ 75KW电机启动电流是90A，在启动电流范围之内，所以是正常的结束语： 75KW电机额定电流是15A，空开的额定电流是20A，15A小于20A所以送电以后不会跳大概有两种方法： 1：经验法，30千瓦的三相异步电动机 (380V)额定电流是30 (电机功率)*2=60A电流。 2：理论计算法，I=P/ (1732xUxcosφxn)，I=P/ (1732xUxcosφxn) , 即三相异步电动机的的额定电流如何计算知乎知乎专栏

起动电流百度百科

电动机的起动电流是指电动机接通额定电压从零速开始起动时输入的线电流。电动机起动电流一般为其额定电流的5～7倍。电动机起动电流过大，对电气设备及电网影响较大。对 Electrical Engineering Question # A 75 HP 230 volt three phase motor takes a line current of 184 A when operating at rated output at an efficiency of 88% Calculate the indications on wattmeters when these are inserted to measure power (a) by two wattmeter method, (b) by the artificial neutral method and (c) by the T methodAnswer in Electrical Engineering for jim #
