Abstract EN
The torque of the main drive system is one of the most important force and energy parameters of the rolling mill, and the strain type torque online telemetry system is a practical method for measuring torque parameters.
The strain gauges and transmitters on the rotating shaft are driven by a high-frequency induction power system.
Their installation, debugging, and maintenance are cumbersome, and their very low power transmission efficiency (PTE) has become a challenging problem for online telemetry systems.
In this paper, a magnetic coupling resonant wireless power supply method is utilized to replace the high-frequency induction power supply.
Through theoretical and experimental research, it is concluded that the magnetically coupled resonant wireless power supply method can realize long-distance power supply, overcoming many shortcomings of the high-frequency induction power supply system.
In the laboratory, a maximum PTE of 83.7% is obtained for a transmission distance of 50 mm.
Under the influence of environmental factors common for the transmission shaft of a rolling mill, the PTE decreases by 34%, but normal operation of the system can be achieved by adjusting the compensation capacitance.
The proposed system provides a guarantee for a long-term stable power supply on the measured axis of a rolling mill torque online telemetry system.
