| 摘 要： | 在线监测SO2的含量及其趋势变化，对SF6电气设备的故障预警和故障分析具有极其重要的意义。基于紫外荧光法的SO2在线监测装置，设计了SO2紫外荧光检测光路系统、检测电路及软件、在线无损气体采样系统。其中，在线无损气体采样系统不仅能自动采样，还能回收气体，避免待测气体的损耗、泄漏和污染，并支持多种分解气体的同时在线检测。实验测试及现场运行结果表明，该装置完全满足电力设备中SO2的在线监测需求。

| Abstract: | Online monitoring for SO2 and its trend has important significance for fault pre-warning and analysis of SF6 electrical equipment. Based on ultraviolet fluorescence method, an online monitoring device is designed including SO2 UV fluorescence optical path system, detection circuit, software and online lossless gas sampling system. The online lossless gas sampling system has many merits including automatic sampling, gas recovery, gas wastage, leakage and pollution prevention and multiple decomposition gases detection. Experimental test results and field operation show that proposed device can satisfy needs of online SO2 monitoring of power equipment. |
