This product is applicable to power supply voltage 6kv~10kv, motor power 200~5000kw ac motor speed control. The eight-stage starting resistor, thyristor dynamic
braking, and the secondary hydraulic braking with mechanical coordination are used to realize the acceleration, uniform speed, and all control of the parking.
The control of operation mode of lifting movement, overhaul and low speed crawling is shown.
The speed control system is controlled according to the speed of the stroke.
Perfect protection function, such as overwinding, deceleration device, constant speed, 2 m fixed point, etc.
Protection function: the parking of the brake and the secondary brake are stopped immediately.
PLC (high voltage) electric control equipment for mine hoist
