In mines, in systems where the power input voltage is an AC frequency of , the characteristics of AC electric products are controlled by changing the frequency to start smoothly, reducing mechanical impact, and playing a very good protective role in mechanical devices such as belt motor reducers. It extends its service life and provides a variety of operating modes. Users can choose the most appropriate operating mode according to different industrial and mining operations. There is mechanical locking to ensure the safety and reliability of the control device. The starting current is small and the impact on the power grid is reduced. Short-circuit protection, phase failure protection, overload protection, over-voltage protection and under-voltage protection
℃, allowing times of rated current overload in seconds, leakage lockout and leakage protection are provided by the superior switch

Speaking of coal mine safety, what is safety? When there is no danger, there is safety; when there is no shortage, there is completeness. This is safety. The security of the country is the security of Cathay Pacific people and the safety of the people. Security is like a colorful thread that connects our beautiful wishes to form a stable, peaceful and colorful world. But once we violate the coal mine safety operating regulations, it immediately turns into a vicious tiger, opening its bloody mouth and devouring our limbs mercilessly. In mild cases, the skin and flesh may suffer, in severe cases, muscles and bones may be broken, or even death may result.
