132KW 电机,250米距离用多大电缆? 知乎 Zhihu 铜芯用70平方,铝芯用95平方,如果计划后期增加设备,建议加个大一个型号即可!专业销售国标保检电缆,全250千瓦需要3x300平方的铜电缆。 由功率公式P=1732UIcosφ 有I=P/ (1732Ucosφ),所以电流可如下计算: I=250/ (17性能特点
铜芯用70平方,铝芯用95平方,如果计划后期增加设备,建议加个大一个型号即可!专业销售国标保检电缆,全250千瓦需要3x300平方的铜电缆。 由功率公式P=1732UIcosφ 有I=P/ (1732Ucosφ),所以电流可如下计算: I=250/ (1732x038x085)=447A (用三相市电计算,功率因数取085) 由于电流值较大,建议选铜线。 下表是铝线截面和其安全载流量的对照表,故先把铜线对应的电流值447A250千瓦需要多大的电缆百度知道 Baidu
一、电机功率与配线直径计算 首先要计算100KW负荷的线电流。 对于三相平衡电路而言,三相电路功率的计算公式是:P=1732IUcosφ。Power rating up to 350HP (262kW) Pressure range up to 2800 bar Flow rates from 28 ltr/min to 323 ltr/min Durable Power End Superior quality ductile iron power frame 323 250 310 370 560 ** All flows are based on 100% volumetric efficiency BC TAECHANG INDUSTRIAL CORPORATION #6401, YoungjuDong, JungGu, Busan, Korea POWER RATING UP TO 350HP (262kW)
Sep 30, 2016· 250kw用多大电缆合适 如果是铜电缆,电缆沟敷设,敷设距离100米以内的话,选用2根120平方的电缆,如果选用单根需300平方,但300平方的敷设难度较大。 250千瓦需要3x300平方的铜电缆。 由功率公式P=1732UIcosφ 有I=P/ (1732Ucosφ),所以电流可如下计算: I=250/ (1732x0Jul 26, 2019· 4x185的铜芯电缆能带226~262KW的负荷。 查《电气工程》常用数据速查手册知185平方毫米铜芯电线能承受459A电流(单芯,空气中敷设),或 530A电流(单芯,埋地敷设)。 因此负荷功率可如下计算: P=1732UIcosφ=1732x038x459x075=226KW。 这里用标准三相市电电压计算185电缆能带300千瓦吗 185平方电缆能承受多少千瓦 领域开拓网
