power factor

功率因数

Power factor

在电气工程中,交流电力系统的功率因数定义为流向负载的有功功率与电路视在功率的比值,为-1到1之间的无量纲数。实功率为 用于在特定时间内执行工作的电路的容量。 视在功率是电路的电流和电压的乘积。 由于存储在负载中的能量并返回到源,或者由于使来自源的电流波形变形的非线性负载,视在功率将大于实际功率。 负载功率因数发生在通常负载的设备产生的功率然后流向通常被认为是发电机的设备。 在电力系统中,具有低功率因数的负载比具有高功率因数的负载在相同量的有用功率传递下吸引更多的电流。 较高的电流增加了配电系统中的能量损失,并且需要较大的电线和其他设备。 In electrical engineering, the power factor of an AC electrical power system is defined as the ratio of the real power flowing to the load, to the apparent power in the circuit, and is a dimensionless number between -1 and 1. Real power is the capacity of the circuit for performing work in a particular time. Apparent power is the product of the current and voltage of the circuit. Due to energy stored in the load and returned to the source, or due to a non-linear load that distorts the wave shape of the current drawn from the source, the apparent power will be greater than the real power. A negative power factor occurs when the device which is normally the load generates power which then flows back towards the device which is normally considered the generator. In an electric power system, a load with a low power factor draws more current than a load with a high power factor for the same amount of useful power transferred. The higher currents increase the energy lost in the distribution system, and require larger wires and other equipment.

在英语 词典里power factor的定义

字典中功率因数的定义是功耗与输入电压乘以乘积的乘积之比。

The definition of power factor in the dictionary is the ratio of the power dissipated to the product of the input volts times amps.
