摘要
析气性是特殊变压器油关键性能之一,文章研究了烷基苯、合成酯、A和B四种物质及其用量对石蜡基变压器油析气性改进效果的影响。结果表明:相同加量下B的改进效果最优,其次是A、烷基苯和合成酯。0.3%B和10%烷基苯复合使用时不仅显著改善石蜡基变压器油的析气性能,且其他性能完全满足GB 2536-2011的指标要求。
Gassing property is one of key properties of special transformer oils.The modifying effects of alkylbenzene,synthetic ester,A,B and their dosage on gassing properties of paraffinic transformer oils were studied.The results show that under the same dosage,B has the best modifying effect,and the next is A,alkylbenzene and synthetic ester in order.The combination of 0.3% B and 10%alkylbenzene not only modifies remarkably the gassing properties of paraffinic transformer oils,but also satisfies the requirements of GB 2536-2011 specification.
