摘要
阐述了 GIS用避雷器设计中应考虑的主要问题 ;介绍了内部电场的布置形式及大面积电场、小面积电场的场强计算公式 ,并对电极形状与表面粗糙度之间的关系进行了说明 ;详细介绍了电位分布的要求、均压罩形状与电位分布之间的关系及罐体压力设计时应考虑的因素 ;论述了 GIS用避雷器热稳定性的依存关系、几种情况下的放热特性及材料性能对产品性能的影响。
Main aspects in design of GIS type MOA is dealt with.Configuration of inner electric field,stress calculation formula of large scare field and small field are presented.The correlation between electrode and surface roughness is given.A detailed description of requirements of field distribution,correlation between shield electrode shape and field distribution as well as aspects of consideration at pressure of tank are presented.The dependence of thermal stability of GIS MOA,thermal dissipation is some cases and effect of material on apparat behaviour are discussed.At last, the requirements for assembly environment are given.
