摘要
超高压输电公司已安装的油中溶解气体在线监测装置品种多样,所使用的技术及主要原理均有差别,本文通过配置低、中、高三种不同浓度的油样,对多个厂家的油中溶解气体在线监测装置与实验室离线设备数据进行比对测试,通过测量误差试验、测量重复性试验、最小检测周期三个项目的测试和评价,为选用油中溶解气体在线监测装置提供参考依据,并指出现有油中溶解气体在线监测装置普遍存在的问题,最后提出了相应建议以供参考。
A variety of transformer oil chromatographic online monitoring devices are installed in the Extra High Voltage Power Transmission Company,and designed with different technologies and principles.This paper discussed the data accuracy,consistency,and minimum detection period of these transformer oil chromatographic online monitoring devices,through the contrast experiments.The work can serve a quantitative reference for selecting the otransformer oil chromatographic online monitoring devices,and put forward the suggestions for online monitoring devices’problems according to the appraisal process and its result.
