基站与高压电力塔共站的防护分析

随着5G通信技术的发展,5G基站对站点数量的需求越来越大,将电力塔与通信基站结合,是5G基站建设的趋势.但是,基站与高压电力塔共站时需要做好高压电力线对基站的危险影响防护,尤其要关注高压电力线故障时地电位反击对基站及附近居民的影响.从高压电力线对基站的容性耦合、感性耦合和阻性耦合做了分析,并分别从电气安全隔距、导线布置...

Analysis on Protection of Base Station and High Voltage Power Tower Co-site

With the development of 5G,the demand of 5G base stations for the number of sites is increasing.The combination of power tower and communication base station is the trend of 5G base station construction.However,when the base station and the high-voltage power tower are co-site,it is necessary to protect the dangerous impact of high-voltage power line on the base station,especially pay attention to the impact of earth potential counterattack on the base stations and nearby residents when the high-voltage power line fails.It analyzes the capacitive coupling,inductive coupling and resistive coupling of high-voltage power lines.and gives suggestions from the aspects of electrical distance,conductor layout,setting of equalizing voltage ground network,protection of low-voltage power supply network,etc.,which reduces the risk factors and provides an implementable scheme for the co-construction of base station and high-voltage power tower.
