Autotransformer Starting Cabinet 380V-660V 90KW-400KW

In large steel mills, the power of equipment such as blast furnace fans and converter dust removal motors often reaches 90kw to 400kw, which places extremely high demands on the load-bearing capacity and stability of the starting equipment. This autotransformer reduced-voltage starting cabinet, which is compatible with 380V-660V voltage, is specially designed for such high-power scenarios. It can stably drive three-phase motors of the corresponding power range and is a key guarantee for steel production. ​ Its core advantage lies in its remarkable starting current control capability. By adjusting the 65% and 80% voltage taps, the starting current can be reduced to 42%-64% of the direct starting current. The power load in steel plants is dense. If the motor starts directly, the huge current can easily cause a sudden drop in the busbar voltage of the power grid, leading to faults in precision devices such as the temperature control system of the steelmaking furnace and the transmission e…
