摘要：
In order to analysis the influence of copper ion on aging rate of oil-paper insulation, accelerate thermal aging experiments have been designed and performed on oil-paper insulation at two aging temperatures. A number of characteristic parameters such as dissolved gases, degree of polymerization, furfural content, water content and Acid number of oil have been tested periodically. The experiments results indicate that copper ion has a great influence on insulation paper and oil during the aging process; it delayed the degradation rate of insulation paper, which reduced the ratio of CO2/CO by about 11% at 80 degrees C and more than 50% at 130 degrees C. In addition, copper promotes the oxidation of the oil and accelerates the aging rate.
