摘　　要：分析民用10kV变配电系统中的过电压保护,对无间隙氧化锌避雷器的保护原理、设置原则、参数选择进行阐述。以10kV小电阻接地系统与经消弧线圈接地系统的避雷器选择为例,阐述避雷器参数的选型。The overvohage protection of 10 kV transformation and distribution system used in civil buildings is analyzed and the protection fundamentals, setting principles and parameter selection of the zinc-oxide arresters without gaps are presented. Additionally, based on the selection of lightning arresters for 10 kV low resistance grounding system and grounding system with arc-suppression coil, the parameter selection of lightning an＇esters are intro-duced.
