变压器是一种众所周知的电力系统设备,与纸张和压板等固体绝缘体结合使用,以及矿物油等液体绝缘材料,石油基液体。尽管矿物油有明显的缺点,例如后代的有限资源及其非生态友好性质,它的用法仍然无处不在。在环境影响和性能方面,探索超越矿物油的替代流体的必要性日益增加。在全球向绿色能源转变的过程中,这项研究的重点是植物种子油,如玉米油,大豆油,芥子油,和米糠油作为潜在的替代品。该研究评估这些油的基础上的关键变压器的性能,包括击穿电压,含水量,界面张力,粘度,酸度,闪点,和火点。有趣的是,米糠油和大豆油表现出有希望的特性,表明它们可以有效地替代变压器中的石油基流体。此外,该研究扩展到将矿物油与植物种子油以各种成分混合,加入天然和合成的抗氧化剂添加剂范围从0到1%。具有和不具有添加剂的样品之间的比较分析表明,包含1%没食子酸丙酯产生显著的性能改进。例如,包含25毫升矿物油和25毫升大豆油的混合物,补充1%没食子酸丙酯,与测试的其他共混物和添加剂相比,显示出90%更高的有效性。此外,研究采用统计回归分析来建立不同参数变量之间的关系,更深入地了解这些混合油在变压器应用中的性能和相容性。这项全面的调查强调了植物种子油作为矿物油的可行替代品的潜力,为电力系统中环保解决方案的发展做出贡献。
Transformer is a well-known power system apparatus utilized in conjunction with solid insulations such as paper and press board, as well as liquid insulations like mineral oil, a petroleum-based fluid. Despite the notable drawbacks associated with mineral oil, such as limited resources for future generations and its non-eco-friendly nature, its usage remains ubiquitous. There is a growing imperative to explore alternative fluids that surpass mineral oil in terms of environmental impact and performance. Amidst the global shift towards green energy, this study focuses on vegetable seed oils such as corn oil, soybean oil, mustard oil, and rice bran oil as potential substitutes. The research evaluates these oils based on key transformer properties including breakdown voltage, water content, interfacial tension, viscosity, acidity, flash point, and fire point. Interestingly, rice bran oil and soybean oil exhibit promising characteristics that suggest they could effectively replace petroleum-based fluids in transformers. Furthermore, the study extends to blending mineral oil with vegetable seed oils in various compositions, incorporating natural and synthetic antioxidant additives ranging from 0 to 1%. Comparative analyses between samples with and without additives reveal that the inclusion of 1% propyl gallate yields outstanding performance improvements. For instance, a blend comprising 25 ml of mineral oil and 25 ml of soybean oil, supplemented with 1% propyl gallate, demonstrates 90% higher effectiveness compared to other blends and additives tested. Moreover, the research employs statistical regression analysis to establish relationships between different parameter variables, providing deeper insights into the performance and compatibility of these blended oils in transformer applications. This comprehensive investigation underscores the potential of vegetable seed oils as viable alternatives to mineral oil, contributing to the advancement of eco-friendly solutions in power systems.
