摘要

人们对在电力变压器中使用天然酯作为绝缘液体的兴趣越来越大，但目前使用这些液体的经验不足以满足成本效益和可靠的现场应用。为了缩小这一差距，我们进行了一项研究，测量了市售的天然酯基绝缘液的性能，并将其老化性能与传统矿物油基绝缘液进行了比较。此外，还比较了天然酯和矿物油中纤维纤维板保温材料的老化性能。本研究模拟了矿物油和天然酯填充变压器在不同条件下的FDS响应，包括换油、固体绝缘干燥、用新的天然酯基绝缘液替代老化矿物油。

Comparative study to understand behaviour of natural ester as transformer insulating liquid

There is a growing interest to use natural esters as insulating liquids in power transformers, yet current experience in use of these liquids is inadequate for cost effective and reliable field applications. To reduce this gap a study has been done to measure the properties of a commercially available natural ester based insulating liquid and compared its ageing performances with conventional mineral oil based insulation. Moreover, ageing behavior of cellulosic pressboard insulation in the natural ester is also compared to that of in mineral oil. This study simulate the FDS response of both mineral and natural ester filled transformer under different conditions including, oil replacement, drying out of solid insulation and replacement of aged mineral oil with new natural ester based insulating liquids.
