中文摘要:

用于对振动、温湿度、倾斜、风偏等参数进行实时监测的输电线路传感器节点,是保障输电线路安全运行的重要组成部分。然而,当前供能方式(如化学电池和太阳能)存在寿命短、环境适应性差等不足,难以满足持续稳定的供电需求。提出了一种结合摩擦电、压电和电磁技术的复合振动取能器件,通过悬臂梁结构和阵列配置优化,实现对特定微风振动频率的高效捕获和转化,为传感节点提供稳定、持久的供电。实验结果表明,所提复合式能量采集器能够在自然微风振动环境下稳定供电,输出平均功率为3.7 mW,每日发电量约25.26 mA?h,足够供给每日功耗10.39 mA?h 的自组装传感节点组工作。这一成果为输电线路在线监测系统提供了可靠的供能方案,对保障输电线路的安全运行和稳定供电具有重要意义。

英文摘要:

The sensor nodes on power transmission lines are essential for real-time monitoring of parameters such as vibration, temperature, humidity, tilt, and wind deflection, playing a critical role in ensuring the safe operation of transmission lines. However, current power supply methods, such as chemical batteries and solar energy, suffer from limitations like short lifespan and poor environmental adaptability, making it difficult to provide consistent and stable power. This study proposes a hybrid vibration energy harvester that integrates triboelectric, piezoelectric, and electromagnetic technologies. By optimizing a cantilever beam structure and array configuration, the device efficiently captures and converts specific micro-wind vibration frequencies into stable and enduring power for sensor nodes. Experimental results demonstrate that the hybrid energy harvester can stably generate power under natural micro-wind vibration conditions, achieving an average output power of 3.7 mW and a daily energy yield of approximately 25.26 mA?h, sufficient to power a self-assembled sensor node group with a daily energy consumption of 10. 39 mA?h. This innovation provides a reliable energy solution for online monitoring systems of power transmission lines, significantly contributing to their safe operation and stable power supply.
