配网带间隙避雷器在线检测装置的研制

open access: yesDianci bileiqi
作为配电线路雷电过电压防护的最有效设备之一,带串联间隙避雷器大量应用于配网架空线路。部分避雷器在运行过程中发生故障后,一旦遭受雷击容易发生压力释放,并造成线路跳闸或绝缘子及导线损坏。本文对串联间隙避雷器的本体在密封性能劣化后的变化进行了分析,选取了绝缘电阻值作为评判其健康状态的依据;提出了配网带间隙避雷器在线检测装置的技术要求;研制出一种配网带间隙避雷器在线检测装置,能够在线检测配网带间隙避雷器的健康状态,提前发现密封劣化的避雷器,方便运维人员及时更换,减少因避雷器损坏造成的线路跳闸或其他运行事故。
