摘　　要：在电力物联网蓬勃发展的当下,如何持续且长时间地供能成为了数以万计的传感器所要面临的技术难题。摩擦纳米发电机(triboelectric nanogenerator,TENG)作为新崛起的高效供能技术,在传感器的自供电领域有着非常广阔的应用前景。文中基于摩擦电工作原理,利用多层弹性体结构的垂直接触分离TENG,设计出一种面向输电线路微风振动的多层弹性体TENG能量采集装置。通过振动能量采集器输出性能测试平台模拟输电线路微风振动状态,对不同频率和振幅下能量采集器的基本电气特性进行测试,结合电能管理策略,构建面向输电线路微风振动的振动能量采集自供电系统,实现宽频带振动能量的高效采集与转换,完成对商用传感器的供能。最后,通过输电线路振动缩比模型验证文中所设计振动能量采集装置的有效性与可行性。文中设计的振动能量采集自供电系统能够有效地将输电线路宽频振动能量转换为电能,具有结构简易、经济性好的特点,解决了电力物联网传感器不能持久绿色供电的问题。At present,with the vigorous development of power Internet of Things,how to sustain and supply energy for a long time has become a technical problem that tens of thousands of sensors need to face.Triboelectric nanogenerator(TENG),as a new high efficiency energy supply technology,has a very broad application prospect in the field of sensor self-power supply.In this paper,based on the working principle of triboelectricity,a multi-layer elastic TENG energy harvesting device for transmission line breeze vibration is designed by using the vertical contact of the multi-layer elastic structure to separate the TENG,and the transmission line breeze vibration state is simulated by the output performance test platform of the vibration energy collector.The basic electrical characteristics of energy collectors at different frequencies and amplitudes are tested,and combined with power management strategies,a self-power supply system for vibration energy acquisition for transmission line breeze vibration is constructed,which realized efficient acquisition and conversion of wide-band vibration energy and completed energy supply for commercial sensors.Finally,the validity and feasibility of the vibration energy collection device designed in this paper are verified by the vibration reduction model of the transmission line.The vibration energy acquisition self-power supply system designed in this paper can effectively convert the broadband vibration energy of the transmission line into electric energy,and has the characteristics of simple structure and good economy,which can provide a new solution to solve the power supply problem of sensors for power Internet of Things.
