兰州地区复合绝缘子应用分析

The Integrated Application Analysis of Composite Insulator in Lanzhou Area

由于兰州特殊的地理环境,需要同时考虑恶劣天气和重度环境污染对外绝缘设备的双重影响。本文在线路塔材改造投入最低的情况下,分析耐污闪性能和有效爬电距离之间的关系,并在连接方式固定的情况下,分析芯棒直径与机械性能的关系,以满足兰州地区外绝缘设备的综合要求。

Because of the special environment in Lanzhou area,it needs to consider the double effection of the heavy weather and the environmental pollution to the external insulation equipments.The paper analyzes the relationship of the anti-pollution characteristic and the valid creepage distance.Also,it analyzes the relationship of the mandril diameter and the mechanical characteristic to meet the requirements of the external insulation equipments.
