变压器容量kVA与电机kW的关系JE电机引接线JE电机引出线JE电缆
The relationship between transformer capacity kVA and motor kW
变压器容量为100-630kVA，电机功率为几-几百kW，kVA为视在功为，kW有功功率，kVAR为无功功率。 有功功率与无功功率平方之和等于视在功率。 他们的关系是: 有功功率=视在功率*功率因素 即P=S*cosΦ。 如一台 ...
The capacity of the transformer is 100-630kVA, the power of the motor is several - hundreds of kW, the kVA is viewed as the work, the kW has the power of active power, and the kVAR is the reactive power. The sum of the active power and the square of the reactive power is equal to the apparent power. Their relationship is that the active power = the power * power factor is P=S*cos =. for example, a...
