چکیده
|
In order to evaluate the reliability of using repulped cellulose in transformers, the aging process was applied on standard and repulped cellulose in a laboratory accelerated model by increasing of temperature to 150 ° c and their behavior was monitored by measuring the amount of 2-furfural released in oil by hplc (high performance liquid chromatography) in the consecutive aging periods and the results was compared. the results were fitted to estimate the aging behaviors according to the content of 2 - furfural that released in oil. the obtained results showed that behavior of two types of cellulose is almost the same. therefore, it can be concluded that the moulded insulating parts made of repulped cellulose can be used in the insulation system of power transformers with a good and acceptable reliability.
