摘要

气体是SF

电气设备内部存在局部放电和异常发热时的主要特征分解产物，对于设备潜伏性缺陷的诊断具有重要意义。由于超特高压电气设备气室大且装有吸附剂，设备潜伏性缺陷产生的分解产物体积分数通常低于现场检测仪器的最低检出限，因此现阶段缺少能够有效检测微量SO

检测装置，低温富集将被测气体中的大部分SF

Abstract

is the main characteristic decomposition product of SF

-insulated electrical equipment under internal partial discharge and abnormal heating

which is of great significance for the diagnosis of latent defects in such equipment.Due to the large gas compartment and the installation of adsorbents in extra-high voltage (EHV) and ultra-high voltage (UHV) electrical equipment

the concentration of decomposition products generated by latent defects is usually lower than the minimum detection limit of field instruments. Therefore

there is a lack of effective detection devices and technical means for trace SO

at present. In this paper

a trace SO

detection device based on lowtemperature enrichment and ultraviolet fluorescence method is developed.Low-temperature enrichment liquefies most of the SF

in the measured gas

elevating the SO

concentration and thus improving the detection sensitivity. The ultraviolet fluorescence method for SO

detection features small sample consumption and non-destructive measurement

making it suitable for combination with the low-temperature enrichment unit to realize the detection and analysis of SO

at the 10

-9

level.Experimental results show that the SO

enrichment factor is approximately 10 times at an intake volume of 25 L

and about 20 times at 50 L. The device can detect SO

at a concentration of 50×10
