22kw-75kw Autotransformer Start Cabinet

The working environment in mining operations is harsh, mostly located in remote areas with relatively poor power grid conditions. Moreover, the motor equipment is mostly high-power and heavy-load, which poses a great challenge to the performance and reliability of the starting equipment. This autotransformer reduced-voltage starting cabinet, compatible with 380V-660V voltage, has a power range of 22kw-75kw and can stably drive 17kw-60kw three-phase motors, providing an efficient and reliable motor starting solution for mining operations. ​ The motor equipment commonly used in mining, such as crushers, hoists and ventilators, have a huge starting current. If direct starting is adopted, it is very likely to cause the collapse of the mine power grid and affect the entire mining operation. This starting cabinet reduces the starting current to 42%-64% of the direct starting level through 65% and 80% voltage taps, effectively protecting the fragile power grid system of the mine, preventing…
