摘　　要：分析了现行消弧装置的优缺点,提出了一种使用自动补偿消弧线圈与故障相快速接地装置相配合使用的新型的消弧方法,阐述了基于该消弧方法的消弧装置的整体结构以及各部分的工作方式,讨论了所使用各部分装置的动作配合方案。该消弧方法能够兼顾快速熄灭电弧和减小接地电流,使小电流接地系统单相弧光接地问题得到很好的解决,能够进一步提高电网的安全性和供电质量。The merits and demerits of present arc-suppression devices were analyzed. A new method that coordinately used automatic tracking compensation arc-suppression coil and grounding phase quick-ground device was proposed. The overall construction of arc-suppression device based on this arc-suppression method and working of various parts were elaborated. The movement coordination plan of various parts installed was discussed. This arc-suppression method could extinguish arc quickly and compensate earth current. Enabled the problem of single-phase ground arcing faults in neutral point non-effectively grounded systems to obtain a good solution, could further enhance the security and quality of electrical network.
