Mining explosion-proof AC vacuum soft starter The device adopts MX2 intelligent drive box, the latest technology developed by the United States BENSHAW, as the core. It can make the motor start in a controlled and smooth way, which is a good solution to the impact to the the grid and mechanical equipment when the motor starts, and extends the service life of the device. The device with the functions of perfect protection and intelligent communication, can be widely used in the coal mine industry to control the tape conveyor, fans, pumps and other motors. With simple operation, intuitive parameter settings, Our Mining AC Vacuum Soft Starter is mainly used in underground coal mines, where there are mixed explosive gases, such as methane. This Reversible Soft Starter is used to control and protect the motors frequently started in the power system, which is 3-phase neutral point ungrounded, with rated voltage 6kV, rated frequency 50hz and rated current up to 300A. If you are interested in our High Voltage Vacuum Soft Starter, please call us at any time.
1. Reduce the starting current, reduce power supply peak current, reduce the cost of distribution equipment. Reduce the abrasionmotor, improve the service life of mechanical equipment. 2. Optional starting parameters are convenient in one soft starter starting different motors. 3. Soft starter inspects motor feedback voltage to realize closed loop control, ensure the motor start-up success in different conditions and different loads. 4. A variety of starting ways: voltage ramp starting way can get the maximum output torque; Current limiting can realize biggest limitations of the soft start starting current. 5. Reliable quality assurance: using computer simulation design; SMT production process; Excellent electromagnetic compatibility performance, High temperature aging, vibration test of the machine before delivery.
