摘　　要：10kV配网类避雷器在我国配网过电压保护中起重要作用,长期以来基于GB/T 11032-2010(IEC 60099-4:2009 MOD)标准的要求,我国10 kV无间隙金属氧化物避雷器产品质量有了稳定的提高。近年来,随着国网、南网对重负载配电避雷器的成功研制和推广应用,以及IEC 60099-4:2014、新修订的GB/T 11032-2020标准的要求内容变化,对于10kV配网类无间隙金属氧化物避雷器的整体设计、电阻片选型、能量耐受要求等诸多方面提出了更高要求。笔者分析了当前常用的10 kV配网类无间隙金属氧化物避雷器的关键性能,针对新国标要求的变化,分析了今后避雷器产品检测中的侧重点和对避雷器性能的新要求。10kV distribution class arrester plays an important part in our nation overvoltage of distribution network protection. Based on the standard of GB/T 11032-2010( IEC 60099-4: 2009 MOD),the product quality of 10kV metal-oxide surge arresters without gaps in our nation has increased steadily from a long-term perspective. Recently,with the successful development and promotion of heavy duty distribution class arrester by state grid corporation of China and China southern power grid company kimited,as well as the revision of IEC 60099-4: 2014,GB/T 11032-2020 standards,there emerge higher requirements of 10 kV metal-oxide surge arresters without gaps in various aspects,such as the overall design,resistors choice,and withstand energy. In this paper,we evaluate the key performances of the current 10 kV metal-oxide surge arresters without gaps,and emphasize the focus of arrester product inspection and new requirement of the arrester according to the new contents of the standard.
