變壓器容量kVA與電機kW的關系JE電機引接線JE電機引出線JE電纜

The relationship between transformer capacity kVA and motor kW

變壓器容量為100-630kVA,電機功率為幾-幾百kW,kVA為視在功為,kW有功功率,kVAR為無功功率。 有功功率與無功功率平方之和等于視在功率。 他們的關系是: 有功功率=視在功率*功率因素 即P=S*cosΦ。 如一臺 ...

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...
