摘　　要：为了保证特高压换流变压器油纸选型工作的顺利开展,结合国内外文献以及本课题组相关研究成果,从影响油纸老化的因素、油纸复合绝缘在不同电压作用下的绝缘强度以及空间电荷对油纸复合绝缘老化和绝缘性能的影响3方面阐述油纸选型应着重考虑的因素,分析目前市场所售绝缘油纸的基础性能,为特高压换流变压器油纸选型工作的开展奠定理论基础。In order to ensure the material selection work of UHV converter transformer, this paper overviews the overseas and domestic research literatures combined with the studies of our group, the factors to be mainly considered in oil and paper selection are preserted from analyzing the influence aging factors of oil-paper insulation, the insulation strength of oil-paper composite insulation under different voltage and the influence of space charge to the aging of oil-paper and insulation The basic properties of the current market insulation material is analyzed to supply theory basis for the material selection work for UHV converter transformer.
