摘　　要：介绍了一种基于C-GIS的35 kV插拔式避雷器的结构、特点,对避雷器的电位进行了模拟计算,并验证了一套设计方案。通过ANSYS软件施加激励电场,分析发现若不采取均压措施改善电位分布,在长期运行中高压端的氧化锌电阻片会因受到过电压而加速老化,电阻片电位分布不均匀,电阻性能被破坏,从而导致其他电阻片承担电压值增大,最终造成整支避雷器的损坏,使避雷器预期运行寿命缩短。研究结果对插拔式避雷器的设计和参数选取具有重要参考价值。This paper introduces the structure and calculation of a set of 35 kV lightning arrester based on C-GIS.Through the analysis of exciting electric field applied by ANSYS software,it is found that if voltage equalizing measures are not taken to improve the potential distribution,the zinc oxide resistor at the high-voltage end will get aged quickly due to overvoltage in long-term operation.This will cause the uneven potential distribution of the resistor,and the damage of the resistance performance,resulting in the increase of the voltage value borne by other resistors,and eventually leading to unexpected shortening of service life.The results of this paper have important reference value for the design and parameter selection of plug-in arrester.
