大功率离心式风机采用全压直接启动时,过大的启动电流导致供电系统电压大幅度下降,缩短了电动机的使用寿命。通过对离心式风机启动线路的改造,在一定程度上解决了启动时电压下降对供电网络的冲击,减轻了对电动机及所带动的设备造成机械损伤,也降低了能耗。中央储备粮临沂直属库 When the high-power centrifugal fan is started directly with full pressure, an over-large starting current causes the voltage of the power supply system to drop drastically and the service life of the motor is shortened. Through the transformation of the start-up circuit of the centrifugal fan, to a certain extent, the impact of voltage drop on the power supply network at startup is solved, the mechanical damage to the motor and the driven equipment is reduced, and the energy consumption is also reduced.
