旋转机械状态监测无线磁耦合供电能效优化
Energy efficiency optimization of wireless magnetic coupling power supply for rotating machinery condition monitoring
摘要
Abstract
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.关键词
