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

The motor power of crude oil transfer pumps, catalytic cracking circulation pumps and other equipment in large-scale oil refineries often reaches 90kw to 400kw. The operating status of these devices directly affects the efficiency and safety of oil refining production, and the power adaptability and oil and corrosion resistance of the starting equipment are required to be extremely high. This 380V-660V voltage autotransformer reduced-voltage starting cabinet is specially designed for high-power motors in oil refineries, ensuring a stable and efficient production process. ​ Its core advantage lies in the precise control of the starting current and torque. Through the regulation of 65% and 80% voltage taps, the starting current is reduced to 42%-64% of the direct starting current, avoiding the impact on the power grid of the oil refinery during startup and preventing the failure of precision equipment such as the temperature control system of the hydrogenation reactor and the online chr…
