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

The power of the rotary kiln drive motors and raw material grinding machines in large cement plants is generally between 90kw and 400kw. These devices are the core production facilities of cement plants. Once they fail to start, it will cause the entire production process to come to a standstill. This autotransformer reduced-voltage starting cabinet, which is compatible with 380V-660V voltage, is specially designed for high-power and heavy-load motors in cement plants to ensure stable production operation. ​ In terms of starting performance, this starting cabinet reduces the starting current of the rotary kiln drive motor to 42%-64% of the direct starting current through 65% and 80% voltage taps, avoiding the impact on the cement plant's power grid during starting and preventing the shutdown of auxiliary equipment such as the preheater fan and cooler due to voltage fluctuations. The rotary kiln drive motor is a heavy-load starting device. The starting torque is synchronously reduced t…
