在交流、直流及交流叠加直流电场下，进行不同烃组成变压器油析气性研究，同时考察添加剂对油析气性影响情况。研究结果表明，油中芳烃含量是决定变压器油析出气体还是吸收气体的关键因数；相同温度和电场强度下，纯交流电场下油的析气或吸气最大，交直流叠加电场次之，纯直流电场下最小；在规定的使用量下，添加剂对油的析气性没有明显影响。

Gassing tendency of transformer oil with different hydrocarbon compositions in AC,DC electrical field or AC?DC mixed electrical field are investigated according to the standard at home and abroad.The influence of additives on gassing tendency of transformer oils was observed at the same time.The results show that the aromatics content is the key factor,which decide gassing or absorbing gas of transformer oil.At the same temperature and electric field strength,the tendency of gassing or absorbing gas of oils in AC electric field is the largest,the AC and DC mixed electric field takes the sec-ond,and the smallest value of gassing or absorbing gas is in the DC electric field.The use of additives has no obvious effect on gassing tendency of oils in specified dosage range.
