通常来说，消费者在选择电抗器时都希望购买到牌子好的电抗器。
电抗器的主要作用
1、进行无功补偿和谐波治理
2、提高变频器的功率因数
3、阻止电网的波动

4、减少整理单元对电网的污染(电抗器)

      我们知道变频器的原理把交流转换为直流再变交流的过程是产生谐波的圆头，会对我们的电网造成很大污染。

因为在变频器的接线中会有配件供我们选择以减少这种污染，但这种不是必须的。
变频器的操作手册标准的接线都会提示我们进行电抗器和滤波器的外围选配件的使用，那实际当中为减少成本我们很少用这些配件的都是直接接电源线和电机线。

      

       We know that the principle of the frequency converter converts AC to DC and then to AC is a round head that produces harmonics, which will cause great pollution to our power grid.

       Because there are accessories for us to choose in the wiring of the inverter to reduce this pollution, but this is not necessary.
The standard wiring of the inverter operation manual will prompt us to use the peripheral options of the reactor and filter. In practice, we rarely use these accessories to directly connect the power line and the motor line to reduce costs.(电抗器)
