云数据中心（IDC）与高压变电站共站建设时,变电站的工频磁场会对共站址建设云数据中心的信息存储设备产生不良影响。为了确定云数据中心合理的工频磁场限值、确保云数据中心信息设备的电磁安全,比较分析了云数据中心工频磁场的测量结果、计算结果及公众全天工频磁场限值;并对根据工频磁场抗扰度严酷要求研制的用于云数据中心信息存储的服务器进行了工频磁场抗扰度测试。结果表明,当控制云数据中心与变电站强工频磁场源的距离〉10 m时,通信云数据中心的稳定持续工频磁场抗扰度和短时工频磁场抗扰度的磁场强度分别取100A/m和1 000 A/m;此外,通过改善信息存储设备耐受工频磁场的特性,可以取消云数据中心建筑物的工频磁场屏蔽措施,节省巨额屏蔽费用。所研制的服务器能够耐受与变电站共站的云数据中心可能出现的最为严酷的工频磁场环境。

英文摘要：

When the internet data center （IDC） co-sites with high voltage substation, the power frequency magnetic field produced by substations may generate hazard influence on information storage servers in co-sited IDCs. In order to de- termine the suitable power frequency magnetic field limit of IDC and to ensure the electromagnetic safety of information equipment in IDC, we analyzed and compared the measured and calculated results of power frequency magnetic field and the whole-day limit of the general public on power frequency magnetic field. The power frequency magnetic field im- munity of the information storage servers which were developed according to the most severe requirements on the power frequency magnetic field immunity was tested. The results show that the steady continuous power frequency magnetic field immunity and the short-time power frequency magnetic field immunity will be equal to 100 A/m and 1 000 A/m, re- spectively, by properly controlling the distance between IDC and the strong magnetic sources in substations above 10 m. By improving the power frequency magnetic field withstand characteristics of information storage servers, we can revoke the power frequency magnetic field shielding measure of IDC buildings and save huge shielding cost. Moreover, the de- veloped information storage servers can withstand the most severe environment of power frequency magnetic field, which is possible to appear in IDC co-sited with substation.
