摘　　要：分析了现行消弧装置的优缺点,提出了一种自动补偿消弧线圈与故障相快速接地装置相配合使用的消弧方法,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,讨论了所使用的各部分装置的动作配合方案。该消弧方法兼有快速熄灭电弧和减小接地电流的优点,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 drawbacks of existing arc-suppression devices are analyzed. A new method of coordinated using automatic tracking compensation arc-suppression coil and fault-phase quick grounding device is proposed. The overall construction of an arc-suppression device based on the present arc-suppression method and operation principle of its various parts are elaborated. The movement coordination plan among its various parts installed is discussed. With the presented arc- suppression method, the arc can be extinguished quickly and the grounding current can also be reduced, enabling the problem of single-phase ground arcing faults in neutral point of non-effectively grounded systems to obtain a good solution. Further enhancing the security and the power supply quality of the electrical network is obtained.
