摘　　要：针对高压架空线路状态监测传感器的电源瓶颈问题,利用温差发电技术收集线路接续金具热能是一种极具前景的供电方案。明确线路运行条件对温差发电性能的影响是保证传感器可靠供电的重要前提。设计了一种模拟接续金具不同操作条件的温差发电实验平台,在实验室环境下,分析不同因素对温差发电输出特性的影响,包括负荷电流、环境温度、日照强度、风速和风向等,并进行温差发电功率的回归分析。研究结果表明,温差发电功率与负荷电流呈正相关关系,与日照强度呈负相关关系,随风速和环境温度的增加呈现先增大后减小的趋势,而与风向之间无明显变化规律。该研究为基于温差发电技术的高压架空线路状态监测传感器电源设计提供了重要参考。Aiming at the power bottleneck problem of the state monitoring sensor of high-voltage overhead line,it is a promising power supply scheme to collect the thermal energy of the connection fittings in lines by using the thermoelectric power generation technology.It is an important prerequisite to clarify the influence of the line operating conditions on the thermoelectric power generation performance for ensuring the reliability of the sensor power supply.A thermoelectric power generation experimental platform was designed to simulate different operating conditions of the connecting fittings,and the influence of different factors on the output characteristics of the thermoelectric power generation was analyzed in the laboratory environment,including the load current,ambient temperature,solar intensity,wind speed and wind direction.The regression analysis of the thermoelectric power generation was carried out.The results show that the power of the thermoelectric power generation is positively correlated with the load current,and negatively correlated with the solar intensity.It first increases and then decreases with the increase of the wind speed and ambient temperature,but has no obvious change law with the wind direction.The study provides an important reference for the power supply design of the state monitoring sensor of high-voltage overhead lines based on the thermoelectric power generation technology.
