【摘要】 晋东南-南阳-荆门1000 kV特高压交流试验示范工程已于2009-01-06成功投运,至今系统运行平稳,设备状态良好。电科院东芝避雷器有限公司为该工程提供了GIS型和瓷套型避雷器产品。基于此,较详细地介绍了GIS型和瓷套型避雷器的研发过程和实绩。大容量电阻片、GIS型避雷器和瓷套型避雷器的研发工作都是在株式会社东芝相关关键技术的基础上进行的。大容量电阻片完全满足1000 kV特高压交流GIS型避雷器和瓷套型避雷器要求,具有足够安全裕度,并早已实际应用于500 kV和750 kV瓷套型避雷器。GIS型避雷器电位分布的解析结果和实测结果相当一致,满足标书和技术协议要求。瓷套型避雷器属国际首创产品,应用了4项株式会社东芝具有实际运行业绩的关键技术,特别是减震技术(装置)大幅度减小了瓷套根部应力,从而满足抗地震要求。同时在介绍研发过程和成果的基础上,进行研发工作小结,以便积累经验提高认识,将来更好地为其它特高压交流工程服务。

【Abstract】 On January 6,2009,Jindongnan-Nanyang-Jingmen 1000 kV UHV AC pilot demonstration project was successfully put into operation,so far the system is running smoothly and equipment is in good condition.EPRI Toshiba Arrester Co.,Ltd.provides GIS and porcelain housed surge arresters.The research and development process and performance of GIS and porcelain housed surge arresters are reviewed detailedly.Research and development work,including high energy capacity ZnO elements,GIS and porcelain housed surge arresters,is based on the key technologies of Toshiba.High energy capacity ZnO element,which has sufficient safety margin,meets the requirements of 1000 kV GIS and porcelain housed surge arresters fully,and has actually applied to 500 kV and 750 kV porcelain housed surge arresters.Potential distribution of GIS surge arresters analytical results and measured results are consistent,and meet the requirements of bid documents and technology agreements.Porcelain housed surge arresters are an international ground-breaking products,which apply four key technologies with the actual operation performance of Toshiba.Especially the damping technology(device) significantly reduces the root stress of porcelain bushing to meet anti-earthquake requirements.On the basis of introducing the development process and results,we summarize research and design work,in order to accumulate experience and raise awareness,and better serve for other UHV AC projects.
