摘　　要：避雷器配置是变电站设计的重要工作之一,变电站通用设计中的避雷器配置并非任何情况下都合理。采用雷电侵入波过电压仿真计算,确定避雷器到被保护电气设备间的最大电气距离,可有效调整完善电气设备的布置方案。本文以某500kV变电站为例,对初期接线方式和不同规模分别计算,提出500kV配电装置布置型式或接线方式的改变会导致避雷器配置方案发生变化的结论,研究结论可供变电站设计人员借鉴。MOA installation scheme is one of the important tasks in substation design,and in the general design of substations,the scheme is not reasonable in all cases.The maximum electrical distance between MOA and the protected electrical equipment can be determined by simulation calculations of lightning overvoltage.According to this,the designer complete the layout.This paper takes the project of 500 kV substations as a case to study different wiring modes and different construction scales,the corresponding MOA installation scheme arc obtained,it is concluded that changes in the arrangement type or electrical circuit connection mode of 500 kV electrical switchgear will lead to changes in the installation scheme of MOA.The conclusion is of reference to substation designers.
