90千瓦电机正常运行时的电流和启动时的电流分别是多少 May 23, 2020· 90千瓦电机的工作电流和启动电流的大小 对于三相异步电动机它的工作电流一般与电机的极对数的多少有关系，比如拿90千瓦的电机来说如果是两极的电机它的额定工作电流大约是160A左右；如果是四极的电机，它的工作May 23性能特点
May 23, 2020· 90千瓦电机的工作电流和启动电流的大小 对于三相异步电动机它的工作电流一般与电机的极对数的多少有关系，比如拿90千瓦的电机来说如果是两极的电机它的额定工作电流大约是160A左右；如果是四极的电机，它的工作May 23, 2020· 90千瓦电机的工作电流和启动电流的大小 对于三相异步电动机它的工作电流一般与电机的极对数的多少有关系，比如拿90千瓦的电机来说如果是两极的电机它的额定工作电流大约是160A左右；如果是四极的电机，它的工作额定电流在164A左右；若是6极的电机，其90千瓦电机正常运行时的电流和启动时的电流分别是多少
Jun 05, 2020· 90千瓦电机正常运行时的电流和启动时的电流分别是多少,三相异步电动机的星三角降压启动控制方式一般在电机功率大于75千瓦以上时使用。对于90千瓦这样大功率的电机其考虑的配线导线主要是主电路中的导线，下面我Jun 29, 2010· 很多人算电流用的是电机功率p=1732*u*i*cosφ,这样少乘了一个电动机的效率，算出来的电流比额定电流要小，选择电缆时要注意。 用1kw，2a估算电流，小功率时偏小，大功三相异步电动机电压是380v，功率是90kw，电流怎么计算
Feb 25, 2020· 90千瓦的三相电机，星三角启动，要配置多大的导线和漏电开关 九十千瓦的三相电机，星三角启动，按照经验公式其工作电流应该是电机功率加倍，也就是说是180安。 我们根据三相电机计算公式实际算一下。 这里我们可May 20, 2019· 连接一台90kv千瓦的电机需要多大的电缆？90kw换算成载流量就是178A，根据电缆载流量表可以查出需要95平方电缆；下面就来介绍下如何计算电缆载流量及选用电缆型号，一台90kw电机，需用多大电缆？选用什么电缆型号规格？
Jun 25, 2011· 90千瓦电机的额定电流约170安要用70平方铜线。 P=1732X380XIX09 (其中P电动机功率，1732为常用值，380三相电压，I电流，09功率因数）； 或者另一种方法：25加Apr 15, 2018· 90KW电动机需要多大空气开关或断路器 1，经验值计算选择。 （1）380V电压，每千瓦2A电流。 （2）3KW以上电机，每千瓦2A电流。 计算如下：I=90×2=180个电流。90KW电动机需要多大空气开关或断路器电动机电工之家
当电机角接时： 线电流＝根号3相电流； 线电压＝相电压。绕组是直接接380的，导线的电流是两个绕组电流的矢量之和 功率计算公式p=根号三UI乘功率因数是对的 用一个钳式电流表卡May 23, 2022· 15千瓦的电机多少槽 ： 这个还真不好回答,电机极对数不同电磁设计不同定转子槽配合不同槽数也不一样,2极15KW有30槽的还有36槽的4极15KW的有36槽也有48槽国外产15千瓦6极电机多少槽 wxkyn
