Arc-suppression Method for Coordinated Using of Arc-extinguish Coil with Grounded-Fault Transfer Device

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.
