变压器固体绝缘的老化诊断

Aging diagnosis of transformer solid insulation

变压器固体绝缘的老化诊断应利用变压器油中的CO、CO_2含量诊断固体绝缘老化,包括利用CO、CO_2浓度及CO_2/CO比值诊断固体绝缘老化和利用m L(CO_2+CO)/g(纸)诊断变压器绝缘寿命。利用油中糠醛分析诊断变压器绝缘老化,包括油中糠醛含量测试方法和利用油中糠醛诊断变压器绝缘寿命。测量绝缘纸/板聚合度诊断变压器绝缘寿命包括绝缘纸的聚合度测量,绝缘纸聚合度判据的应用以及固体绝缘老化的综合诊断。

The aging diagnosis of transformer solid insulation should use the content of CO, CO2 in transformer oil,including the use of concentration of CO and CO2, CO2/CO ratio for diagnosing solid insulation aging and the use of m L（CO2＋CO）/g（paper） for diagnosis of transformer insulation life. Taking use of furfural in oil analyzes and diagnoses transformer insulation aging, including furfural test methods on diagnosis of transformer insulation life. Measuring the degree of polymerization of insulation paper/board for diagnosis of transformer insulation life includes measurement of the degree of polymerization of insulating paper, application of criterion and integrated diagnosis of solid insulation aging.
