90KW-400KW Autotransformer Start Cabinet

The motor power of container quay cranes, portal cranes and other loading and unloading equipment in large ports is generally between 90kw and 400kw. These devices need to be frequently started and stopped, and the port environment is often salt spray and humid, which imposes strict requirements on the weather resistance and frequent start-up capacity of the starting equipment. This 380V-660V voltage autotransformer reduced-voltage starting cabinet can be perfectly matched with high-power loading and unloading equipment in ports, ensuring the efficient operation of port logistics. ​ Port loading and unloading equipment can start and stop more than 50 times a day. Excessive starting current can easily cause voltage fluctuations in the port power grid, affecting the normal operation of other loading and unloading equipment and the dispatching system. This starting cabinet is regulated by 65% and 80% voltage taps. Each start-up can reduce the current to 42%-64% of the direct start-up leve…
