简单介绍
江苏春晨电缆有限公司生产运用YFFB扁电缆口诀计算技巧，YFFBP扁电缆，YFFBPG扁电缆，YFFB扁电缆运用口诀计算技巧，（4）运用口诀计算技巧。用口诀计算常用380V电动机额定电流时，先用电动机配接电源电压0.38kV数去除0.76、商数2去乘容量（kW）数。YFFB扁电缆运用口诀计算技巧若遇容量较大的6kV电动机，容量kW数又恰是6kV数的倍数，则容量除以千伏数，商数乘以0.76系数YFFB扁电缆运用口诀计算技巧
YFFB扁电缆运用口诀计算技巧的详细介绍
江苏春晨电缆有限公司生产运用YFFB扁电缆口诀计算技巧，YFFBP扁电缆，YFFBPG扁电缆，YFFB扁电缆运用口诀计算技巧，（4）运用口诀计算技巧。用口诀计算常用380V电动机额定电流时，先用电动机配接电源电压0.38kV数去除0.76、商数2去乘容量（kW）数。YFFB扁电缆运用口诀计算技巧若遇容量较大的6kV电动机，容量kW数又恰是6kV数的倍数，则容量除以千伏数，商数乘以0.76系数YFFB扁电缆运用口诀计算技巧，误差。由口诀中系数0.76是取电动机功率因数为0.85、效率为0.9而算得，这样计算不同功率因数、效率的电动机额定电流就存在误差。由口诀c 推导出的5个专用口诀，容量（kW）与电流（A）的倍数，则是各电压等级（kV）数除去0.76系数的商。专用口诀简便易心算，但应注意其误差会增大。一般千瓦数较大的，算得的电流比铭牌上的略大些；而千瓦数较小的，算得的电流则比铭牌上的略小些。对此，在计算电流时，当电流达十多安或几十安时，则不必算到小数点以后。可以四舍而五不入，只取整数，这样既简单又不影响实用。对于较小的电流也只要算到一位小数即可。
Error. The 0.76 is the coefficient in the formula from the motor power factor is 0.85, the efficiency was 0.9 and as such, the motor rated current calculation of different power factor and efficiency of the existing error. By the 5 special formula derived by C formula, capacity (kW) and current (A) is a multiple of the voltage level (kV) number 0.76 removal coefficient taking. The special formula is simple and easy to do, but should pay attention to the error will increase. Generally, the number of kilowatts is larger, the calculated current is slightly larger than that on the nameplate; while the smaller number of kilowatts, the calculated current is slightly smaller than that on the nameplate. In this regard, in the calculation of current, when the current of up to more than 10 or a few ah, need not be considered after the decimal point. Four and five can not enter, only take the integer, this is both simple and not affect the practical. The smaller current can be counted as only a decimal.
