Abstract

This paper aims to analyze the effects of accelerated thermal aging on electrical, physical, and chemical properties of natural ester oil. The natural ester oil is made from palm oil. In this experiment, there are two types of aging temperature that are used which 120 and 85. At each temperature there are two types of insulation paper which are insulation paper with pretreatment (dried) and insulation paper without pre-treatment (nondried). The test is carried out for 1008 hours with sampling taken every 336 hours. The experiment results show that the longer aging duration and the higher aging temperature, characteristics such as the water content, the resistivity, the breakdown voltage, the viscosity, and the interfacial tension show decreased performance while the dissolved gas analysis indicates that CO and CO2 are major gases produced that shows paper decomposition. It can also be concluded that the initial water content of the paper also affects the speed of oil degradation.

加速热老化对天然酯油化学、电学和物理性质的影响

本文旨在分析加速热老化对天然酯油电学、物理和化学性能的影响。天然酯油是由棕榈油制成的。在本实验中，采用了120和85两种老化温度。在每个温度下，有两种类型的绝缘纸，即经过预处理的绝缘纸(干燥)和未经预处理的绝缘纸(未干燥)。试验进行1008小时，每336小时取样一次。实验结果表明，随着时效时间的延长和时效温度的升高，纸张的含水率、电阻率、击穿电压、粘度、界面张力等性能下降，溶解气体分析表明，CO和CO2是纸张分解产生的主要气体。还可以得出，纸张的初始含水量也会影响油的降解速度。
