| 摘 要： | 在弱电机房防雷系统建设和工程验收过程中,需要一个全面、实用和直观的评判方法,来评价其防雷系统的防护能力是否达到设备安全的要求。以一个弱电机房防雷工程项目为例,分析并得出影响弱电机房防雷系统可靠性的关键参数是:空间屏蔽效能、传输线缆的屏蔽效能、终端最大脉冲电压设限、机房布线最大开口环的感应电压、均压和泄流能力等。在此基础上,以归纳描述或量化分析的方法,对这些关键参数进行了评估和计算,并得出弱电机房防雷设施效能判定参数表。

| Abstract: | It is necessary for the construction and acceptance of a lightning protection project for weak-current equipment rooms to have a comprehensive,practical and the applicable judgment method to decide whether the capability of a lightning protection system meets the requirements.Taking a lightning protection project for a weak-current equipment room as an example,the key parameters that influence the reliability of lighting protection for weak current equipment rooms are analyzed and obtained.The parameters include the spatial shield efficiency,transmission cable shield efficiency,terminal maximum pulse voltage limits,inductive voltage at the maximum split ring in equipment room cabling,pressure-balancing and discharging capability.The appraisal and computation are conducted on these key parameters,and a parameter list of lightning protection efficiency determination for weak current equipment rooms is presented. |
