摘　　要：在施加和撤去不同强度的直流电场下,研究了不同类型变压器油所构成的油纸绝缘体系空间电荷的积聚和消散特性。结果表明:与石蜡基变压器油相比,环烷基变压器油具有更高的环烷烃含量和适宜的芳烃含量,以及更高的电荷迁移速率,由它们构成的油纸绝缘体系在施加和撤去高压直流电场后,油纸之间电荷积聚量更小且更容易消散,从而有利于换流变压器中油纸绝缘材料中电荷的消散。The space charge accumulation and dissipation characteristics of the oil-paper insulation systems composed of different types of transformer oils were studied under the conditions of applying and removing different intensity of DC electric field.The results show that compared with paraffin-based transformer oil,the naphthenic transformer oils have higher naphthenic hydrocarbon content,more suitable aromatic hydrocarbon content,and higher charge transfer rate,and the oil-paper insulation systems composed by them has less charge accumulation and the charges dissipates more easily after applying and removing the high voltage DC electric field,which is beneficial to the dissipation of charge in oil-paper insulation for converter transformer.
