该恒功率调节器是根据采煤机的电动机的电流来自自动调节牵引速度的装置.它使采煤机运行在一定的电流范围内,即保持输出功率基本上恒定,电机负荷处于额定功率的±10%范围内.
The constant power regulator is a device that automatically adjusts the traction speed based on the motor current of the shearer and allows the shearer to operate within a range of currents that maintain the output power substantially constant and the motor load at ± 10% range.
