摘　　要：零地电压问题一直是数据中心运行课题讨论不可或缺的论题,有论点认为零地电压对数据中心IT设备运行影响很大,甚至会影响IT设备的安全运行,还有论点认为零地电压本身就是数据中心的一种谬论,本文结合设计规范及实际运行经验,分析设计规范对数据中心零地电压的定义,并阐述了零地电压产生的原因及对计算机设备正常运行的影响,提出采用智能配电列头柜、高频UPS、增加隔离变压器、调整接地方案、改变材质、增加高频谐波滤波器等多种解决方案,来降低IT配电系统中的零地电压,消除可能出现的安全隐患。The issue of zero ground voltage has always been an indispensable topic in the discussion of data center operation.Some argue that zero ground voltage has a significant impact on the operation of IT equipment in data centers,and even affects the safe operation of IT equipment.Others argue that zero ground voltage itself is a fallacy in the data center.This article combines design specifications and practical operating experience to analyze the definition of zero ground voltage in data centers in design specifications,and explains the reasons for the generation of zero ground voltage and its impact on the normal operation of computer equipment.It proposes various solutions such as intelligent distribution cabinets,high-frequency UPS,adding isolation transformers,adjusting grounding schemes,changing materials,and adding high-frequency harmonic filters to reduce zero ground voltage in IT distribution systems and eliminate potential safety hazards.
