摘要
实验室自主设计研发了电热混合场下变压器油产气特性装置,首次建立了电热混合场下测定变压器油产气特性的方法,并考察了温度、电场强度、基础油种类以及抗氧剂对变压器油产气特性的影响。研究结果表明:电场和温度场同时存在时,温度场对变压器油基础油产气特性的影响大于电场;变压器油中溶解气含量随电场强度的增加呈略增加趋势,随芳烃含量的增加而增加;不含芳烃的环烷基油与石蜡基油基础油产气特性相当;抗氧剂可使变压器油产气量大幅降低。
A lab device was built for testing gassing characteristics of transformer oil under condition of coexisting electric field and temperature, and the relative test method was established. The effect of temperature, electric field strength, base oil composition, and anti-oxidation additives on gassing characteristics was studied. The results show that temperature has a greater influence than electricity field under the coexisting conditions, the gas content increases with the increase of the electric field strength and the aromatic content of the oil tested. Gassing characteristics performance of naphthenic base transformer oil without aromatics was similar to paraffinic base transformer oil; antioxidant in transformer oil can reduce gas content significantly.
