45kw8极电机空载多少A

45千瓦电机空载电流？百度知道 Baidu

Jun 11, 2020· 45千瓦电机空载电流？ 45KW电机的额定电流约为80~90安培（极数愈大、额定电流约大，如45KW2极的额定电流约为82A，而45KW8极的额定电流约为94A），而空载电流约为额定电流的的20~50%，所以，你说的这种情况属于正常。你对这个回答的评价是？May 26, 2013· 45KW电机工作电流90A左右，一般选电流的两倍，180A的空开不多，就选200A，如果是启动时间较长的（比如风机）选250A的。空气开关又名空气断路器是断路器的一种，只要电路中电流超过额定电流就会自动断开的开关。空气开关是低压配电网络和电力拖动系统45kw电机用多大空开百度知道 Baidu

一台45KW加两台20KW的设备需要多大空开？知乎 Zhihu

May 19, 2019· 2、一台45kW+一台20kW（一台20kW备用）需要同时运行，计算电流大约是130A，断路器可以选用160A； 3、当一台45kW运行时，两台20kW不运行，计算电流大约是85A，断路器可以选用100A。二、假设三台设备都是电热设备： 1、一台45kW+两台20kW需要同时运行，计算电流因为效率的高度非线性汽车低速爬行的油耗可能高于高速行驶就是低负载高油耗超低效率, 的关系体现没有能量不守恒气泵通常为三次方的效率曲线, 也就是说在额定转速点以下, 效率以为何电动机空载的电流比有“负载”的高？知乎 Zhihu
