摘要

椰子油已被认为是电力变压器液体绝缘的替代选择。本文介绍了老化方面的椰子油，比较变压器油。湿椰子油和干湿变压器油分别在120°C的密封和非密封条件下老化。在2周、4周和7周的不同老化期间，观察了颜色、界面张力、酸度、击穿电压和频率介电光谱的变化。在陈酿过程中，椰子油的酸度和导电性水平增加。然而，与变压器油相比，它的击穿强度相当高，显示出用作变压器液体绝缘的可能性。

Aging effect of coconut oil as transformer liquid insulation — Comparison with mineral oil

Coconut oil has been considered as an alternative choice for power transformer liquid insulation. This paper presents ageing aspects of coconut oil in comparison to that of transformer oil. Wet coconut oil and wet and dry transformer oil was aged in sealed and unsealed conditions at 120°C. Variation of color, interfacial tension, acidity, breakdown voltage and frequency dielectric spectroscopy was observed during different aging period of 2, 4, and 7 weeks. In the aging process, the acidity and conductivity levels of coconut oil increased. However, its breakdown strength was considerably high compared to transformer oil showing a possibility of using as a transformer liquid insulation.
