摘要
高压输电系统发生接地短路时,故障电流可达几十kV,地电位升高会造成通信设备损坏,并对工作人员人身安全造成不利影响。根据工程实例,从数据中心与高压变电站共站建设中出现的问题入手,分析了两者共站可能出现的工频电磁场对人身和通信设备的危险影响,从地电位升、接地情况、电磁场环境等几个方面探讨高压变电站对数据中心的电磁干扰,并提出解决方案。
When short circuit fault occurs in HV transmission system,the fault current can reach tens of one thousand ampere,ground potential rise will cause the damage of communication equipments,and affect personal safety. According to the engineering example,when Internet data center is co-sited with high-voltage substation,it analyses the possible danger to people and communication equipment. The electromagnetic interference of HV substation to data center is discussed from several aspects,such as ground potential rise,grounding and electromagnetic environment,and put forward the solution.
