摘要

为了研究不同海拔高度下导线起晕电压特性

应用小电晕笼

结合光纤传输技术

基于虚拟仪器技术

研制出一套光纤数字化高海拔电晕损失测量系统。在试验过程中

通过逐渐升高电压使试验导线起晕

应用该系统对其电晕损失进行测量。可以通过在不同的海拔点测量几种导线的电晕损失

作为不同海拔高度导线起晕电压的判断依据

进行导线起晕电压海拔修正方面的研究。试验结果表明

研制的小电晕笼电晕损失测量系统是准确可行的

同时由于中国交流特高压建设途经高海拔地区的特点

也可以考虑应用该系统进一步研究不同气压、温度、湿度等因素对导线电晕损失值的影响

为中国交流特高压输电线路电晕损失规律的进一步研究打下基础。
