摘要
针对某核电厂220 kV GIS的特点,结合现场解体过程,从装配工艺、现场安装、气体检漏、设备运输、工艺环境等环节,分析现场SF6气体泄漏检测值较出厂值偏高的根本原因,对设备安装和密封性检测提出了建议.
Abstract
Based on the characteristics of a nuclear power plant 220 kV GIS,and combined with the on-site dissolution process,this paper analyzes the basic causes of the higher quantity of SF6 gas leakage on-site than in factory in terms of assembly process,field installation,gas leak detection,equipment transportation,process environment,etc.Finally,some advices are proposed about equipment installation and leakage detection.
