Energy efficiency optimization of wireless magnetic coupling power supply for rotating machinery condition monitoring
针对狭小空间及元件动态运转约束条件下,传统外置电源的传感系统无法适用于旋转设备内部元件状态监测的问题,提出了一种采用拱形耦合线圈的无线传感系统磁耦合供电结构.通过建立耦合线圈的电磁和电路模型,推导出无线供电系统的效率表达式,系统地揭示了耦合线圈结构及位置参数对系统供电能效的影响规律.研究结果表明:增大定子线圈弧心角度及线圈高度、减小耦合线圈空气间隙可有效提升耦合线圈的效率.基于系统的仿真计算对线圈结构参数进行实验优选,当线圈弧心角度为120°、线圈高度为80 mm、耦合线圈空气间隙为2 mm时,系统效率可达到0.571.该研究为面向旋转机械设备状态监测的无线传感系统设计及优化提供了理论支撑.
Aiming at the problem that the traditional external power supply sensing system cannot be applied to the state monitoring of the internal components of rotating equipment under the constraints of narrow space and dynamic operation of the components,a magnetically coupled power supply structure of a wireless sensing system using an arch-shaped coupling coil is proposed.By establishing the electromagnetic and circuit model of the coupling coil,the expression of the limit efficiency of the wireless power supply system is deduced,and the influence of the structure and position parameters of the coupling coil on the energy efficiency of the power supply system is systematically revealed.The results show that increasing the stator coil arc center angle and coil height and reducing the coupling coil air gap can effectively improve the ultimate efficiency of the coupling coil.Based on the simulation calculation of the system and the optimization of the coil structure parameters,the ultimate efficiency of the system can reach 0.571 when the coil arc angle is 120°,the coil height is 80 mm,and the air gap of the coupling coil is 2 mm,which provides theoretical support for the design and optimization of the wireless sensing system for the condition monitoring of rotating machinery and equipment.
