摘要

对GB/T 17623-1998气相色谱法测定绝缘油中溶解气体组分含量的测量不确定度进行了评定。分析了样品脱气、气体转移、标准气浓度、测量重复性等因素对绝缘油中溶解气体组分含量测量不确定度的影响。计算得到该方法测量结果的相对标准扩展不确定度为4.4%。

Abstract

The uncertainty of measuring dissolved gas component content in insulating oil by using gas chromatograph method which was stipulated in GB/T 17623-1998 has been assessed.the influence factors upon the uncertainty of measuring the dissolved gas companent content in insulating oil being analysed

including sample degassification

gas transition

the concentration of standard gas

and repeatability of measured results etc..The relative standard expanded uncertainty of measured results by using said method was 4.4%.
