2018年10月1日 · It is known that natural ester insulating (NEI) oils are promising substitutes for mineral insulating (MI) oils because these oils reduce aging of insulating papers in high-voltage oil-immersed power transformers.

In this study, response surface methodology (RSM) technique is used to determine the optimum concentration of mixed antioxidants which will enhance the oxidative stability of NEI oil. The dielectric strength of the NEI oil is evaluated based on the AC breakdown voltage (BdV).

2022年8月19日 · 因此，本研究的目的是研究将 MI 油与天然酯绝缘 (NEI) 油混合的潜力，以减少变压器应用对 MI 油的高度依赖。 MI 和 NEI 油以不同的混合比例混合。 根据 ASTM D1816 标准对 MI-NEI 混合油进行交流击穿电压测试。 结果发现，以下混合比例（30% MI 油 + 70% NEI 油、20% MI 油 + 80% NEI 油）相比，交流击穿电压显着提高。 未使用的 MI 油。 还检查了混合油的闪点和腐蚀性水平。

Recently, natural ester insulation (NEI) oils are found to be the best candidates to replace mineral-based insulation oils for oil-immersed transformer applications. However, NEI oils are prone to oxidation due to their poor oxidative stability which can be …

2018年10月1日 · A concise review on the methods used to improve the suitability of NEI oils for oil-immersed power transformers is presented in this paper. NEI oils are favorable candidates to replace MI oils because they are biodegradable, less flammable, non-corrosive and more importantly, the dielectric strength of these oils is comparable to that for MI oils.
