Both UHV(ultra-high voltage)AC power transformers and UHV DC converter transformers are of hign capacity and withstand voltage levels.The internal distribution of electric field is very complex,it represents the highest level of oil-paper composite insulation structue and leads system.The UHV DC converter transformers,with high AC and DC composite voltage,are extremly complicated.Based on the practice of the UHV AC experiment and demonstration project and UHV DC demonstration project,the insulation structures of UHV AC transformers and DC converter transformers were introduced in this paper.The layout characteristics of leads and bushings of two kinds of UHV DC converter transformer were analyzed in details.The design requirements and types of main and longitudinal insulation used in UHV AC transformers and UHV DC converter transformers were introduced.After these,the paper puts forward the localization solution of the leads and busings used in valve side of UHV power transformers.
