This article deals with the study the negative lightning impulse breakdown voltage (LI-BDV) of MIDEL 1204 natural and MIDEL 7131 synthetic ester liquids when adding small amounts of specific nanoparticles (NPs); the considered NPs being magnetic (Fe3O4) and insulating (Al2O3 and SiO2) NPs. It is shown that these NPs enhance the LI-BDV of investigated esters. In addition, for a given type of NPs, there is an optimal concentration for which the U50% LI-BDV is the highest. This latter is enhanced by about 16.8% for natural ester with Al2O3 at a concentration of 0.05 g/L; and by about 25.6% for synthetic ester with Fe3O4 at a concentration of 0.05 g/L.

合成和天然酯液体基Fe 3 O 4,Al 2 O 3和SiO 2纳米流体的雷电冲击击穿电压

本文研究了当添加少量特定的纳米粒子(NPs)时MIDEL 1204天然和MIDEL 7131合成酯液体的负雷电冲击击穿电压(LI-BDV);认为NP是磁性(Fe 3 O 4)和绝缘(Al 2 O 3和SiO 2)NP。结果表明,这些NP增强了所研究酯的LI-BDV。另外,对于给定类型的NP,存在U 50% LI-BDV最高的最佳浓度。对于浓度为0.05 g / L的与Al 2 O 3的天然酯,后者的含量提高了约16.8%。含铁的合成酯约占25.6%3 O 4浓度为0.05 g / L。
