GIL/GIS在线监测-SF6气体泄露报警在线监测系统

 

系统概述

 

    随着电力系统的不断发展,SF6电气设备应用越来越广泛,特别是GIS组合电器由于其大大缩小了电气设备的占地面积与空间体积,安装方便、运行安全可靠、维修方便等优点而光泛应用。
 

    纯净的SF6气体无色无味无毒,且不燃,比重是空气的5倍。当装有SF6设备的配电装置室如GIS发生泄漏后,SF6气体在低层空间积聚到一定浓度后,如果工作人员进入室内,会发生大脑缺氧,甚至快速窒息等严重人身安全事故。另外,在电弧以及局部放电、高温等因素影响下,SF6气体会产生如SF4、S2F2、SOF2等高毒分解物,某些分解物遇水产生腐蚀性电解质,这些不仅对人身安全构成严重威胁,而且危害电气设备的正常运行。《电业安全工作规程》(发电厂和变电站部分)特别规定,装有SF6设备的配电装置室必须保证SF6浓度小于1000ppm,除须装设强力通风装置外,还必须安装能报警的氧量仪和SF6气体浓度检测报警仪等监测装置。
