摘　　要：针对高压变电站中SF6气体离线人工采样检测的现状所存在气体浪费和检测实时性差等问题,设计了一种SF6气体在线自动采样监测系统。该系统以SF6气体分析仪和气体采样回路结构作为硬件平台,通过PLC程序和触摸屏进行程序控制,实现了SF6气体的在线采样监测,实现气体各项指标的自动检测及其监测过程的自动化。The SF6 for high-voltage substation in the status offline of the manual sampling detected the presence of gas waste and poor real-time detection of problems, this paper designed a SF6 gas online automatic sampling and monitoring system. Through the PLC program and touch screen program control, the system use analyzer and sampling loop of SF6 structure as the hardware platform, to achieve the SF6 online sampling and monitoring, to achieve the targets the automatic detection of the gas and its monitoring process automatmn.
