摘　　要：某地区投入运行了一条330 kV输电线路,是该地区首次尝试在载波机上复用传输继电保护信号,应用长距离电力线载波传输信号,但是投运后通道干扰太大。文章通过对这条高频通道投入使用前后情况的研究、测试和分析,进一步加深了对高频通道传输质量影响因素的了解,认识到架空导线的施工是影响通道传输质量的重要环节,将为以后输电线路施工提供一定的借鉴。This paper makes a study on the transmission of relay protection signal via power line carrier,and analyses the reasons of big noise caused by power line and other factors afffecting the transmission quality of high frequency channels.It points out that the construction of the over head lines is very important for the transmission quality.It has reference value for the construction of future power transmission lines.
