城市地铁交通防雷装置检测技术规范要点解读

Interpretation of the Key Points in Technical Specification of Detection of Lightning Protection Device for Subway Traffic

贵州属于喀斯特地貌,雷电高发区。目前在贵州规划修建的地铁线路地形差异大,线路落差大,对防雷装置设计、施工及检测要求高。为及时检查发现地铁存在的防雷隐患,2020年11月贵州省市场监督管理局批准发布贵州省地方标准《城市地铁交通防雷装置检测技术规范》,为地铁防雷装置检测提供技术支撑。本文对编制《城市地铁交通防雷装置检测技术规范》的背景进行了分析,介绍了该规范的主要内容,重点对规范的技术要点进行了解析。

Guizhou featuring karst landform is an area with highly frequent lightning.At present,the subway lines planned and constructed in Guizhou have great difference in terrain and big drop gap,which have high requirements on the design,construction and detection of lightning protection devices.In order to timely inspect and find out hidden troubles of lightning protection in subway,The Market Regulation Administration of Guizhou Province approved and issued the Provincial Standard"Technical specification for the inspection of lightning protection system in urban subway traffic"in November 2020,providing technical support for the detection of lightning protection devices in subway.This paper analyzes the background of compiling the standard,introduces the main content of the standard,and analyzes the technical points of the standard.
