摘要
介绍了特高压直流系统避雷器的配置方案,研究了直流避雷器产生电弧的原因,并由此提出了一种直流避雷器灭弧新方案,分析了该方案的理论依据,在现有避雷器在线监测系统的基础上设计了了避雷器灭弧系统,对一步改善避雷器在线监测系统性能提供了一种思路。
The paper presents the configuration plan of the arrester of the extra-high voltage DC system and studies the reasons of producting arc of the DC arrester,and puts forward a new arc-extinguishing plan of the DC arrester.The theoretical basis of the plan has been analyzed.On the basis of the on-line monitoring system of the existing arrester,the arrester arc-extinguishing system is designed.It presents thinking to improve the on-line monitoring system performance of the arrester.
