Wind energy is the most common clean energy in the power system. The use of triboelectricity to collect environmental wind energy in the power system, and based on this development of self-driven sensors for electrical equipment, has important research significance for the development of intelligent electrical equipment. In this paper, based on the principle of rotating triboelectric nanogenerator working in independent layer mode, a shape memory alloy based wind energy collection type triboelectric nanogenerator is designed and manufactured, which can realize the collection of wind energy in electric power equipment environment such as transformers and transmission lines, and can achieve the self-powered sensing effect of physical quantities such as wind speed and wind temperature. Firstly, a theoretical model of the device is built based on Maxwell equations, and the charge transfer law during the operation of the device is analyzed, and the working principle is verified by finite element simulation and experimental test. Secondly, through the experimental test, the factors affecting the output of the device are analyzed, including wind speed, friction material, and the law affecting the output is analyzed theoretically. The results show that the device can be used as a wind speed sensor with good linearity, sensitive response to wind temperature, and as a power source with adjustable internal resistance under different wind speeds.
