Abstract

The basic electrical characteristics of a natural ester oil are experimentally investigated and compared to gas-to-liquid transformer oil with emphasis given to the endurance against surge events. An accelerated degradation test is conducted using a sequence of current impulses generated through a combination wave generator. This test is employed to investigate changes in the electrical conductivity of the oil, serving as a crucial performance indicator for assessing its surge current withstand capability. Experimental results on the surge degradation of the natural ester oil are compared to those of gas-to-liquid oil, which is commonly used in power transformers. A discussion is made on the possible use of natural ester oils as a liquid matrix for environmentally friendly surge-proof nanofluids to substitute transformer oils, which are commonly employed as insulating liquids and coolants in the power industry.

天然酯油的浪涌电流承受能力：与气变液变压器油的比较

对天然酯油的基本电气特性进行了实验研究，并与气液变压器油进行了比较，重点是对浪涌事件的耐受性。使用组合波发生器产生的一连串电流脉冲进行了加速降解试验。该试验用于研究油导电性的变化，是评估其浪涌电流耐受能力的重要性能指标。有关天然酯油浪涌降解的实验结果与通常用于电力变压器的气液油进行了比较。讨论了将天然酯油用作环保型防浪涌纳米流体的液体基质的可能性，以替代电力行业中通常用作绝缘液体和冷却剂的变压器油。
