摘　　要：由于边缘数据中心与传统变电站的防雷设计和耐受能力差异,在运行过程中可能出现因共用接地网带来的雷电过电压问题。分析了现阶段独立数据机房的三级防雷保护措施,提出了多站融合场景下边缘数据中心的共地系统雷电过电压监测方法,采用PSpice软件验证了所设计电路的功能响应。搭建了应用于多站融合场景下边缘数据中心共地系统雷电过电压监测装置,实现了边缘数据中心共地系统的电压监测和数据记录存储,为多站融合变电站的过电压防护提供了工程参考意义。The problem of lightning overvoltage might emerge in operation because data centers and conventional transmission centers share the grounding grid.Differences in lightning protection design and the endurance capacity caused this situation.This paper analyzed the three-level lightning protection measures of the independent data room.In addition,it proposed a lightning overvoltage monitoring method of the common grounding system of the edge data center in the multi-station integration.Moreover,it employed the PSpice software to verify the functional response of the designed circuit.This research constructed a lightning overvoltage monitoring device to realize the voltage monitoring and the data recording and storage.It provides a reference for overvoltage protection of multi-station integrated substations.
