为交流电动机作为降压启动的电抗器，称为启动电抗器。启动电抗器的工作制属于短时工作制，负载运行时间通常不大于2min。

客户应提供交流电动机的额定电压，以便确定启动电抗器的绝缘水平。必须给出启动容量和启动电流两个参数。

为了方便客户使用，启动电抗器线圈有一个抽头，抽头电抗值为额定电抗XQ的85%，或按照客户要求抽头。

Ac motors for the buck started as a reactor,known as activated reactor,Reactor start of the work is short-term work system,load running time is not more than 2 min.

Customers should provide the rated voltage AC motors.In order to determine the start Reactor insulation level.Must bear launch capacity and starting current two parameters.

For the convenience of customers,activated reactor coil there is a tap,tap,anti-ralue of the XQ-85%,or in accordance with customer requirements tap.
