变压器油质量的主要影响因素及改进探讨

Discussion on Main Influence Factors and Improvement of Transformer Oil Quality

评价变压器油电气性能的指标主要是介质损耗因素(90℃)、击穿电压。而变压器油介质损耗因素、击穿电压的影响因素主要是杂质和水分。润滑油茂名分公司通过改造抽真空过滤系统,增强脱水效果,有效降低介质损耗因素和含水量,提高击穿电压,确保变压器油的质量。

Evaluation indices of transformer oil electrical performance are mainly medium loss factor（90 ℃） and breakdown voltage.And main influence factors for dielectric loss factor and breakdown voltage of transformer oil are impurities and moisture.Through transforming vacuum filtering system,dehydration effect was improved,dielectric loss factors and moisture were effectively reduced,breakdown voltage was increased,and quality of transformer oil was ensured.
