Abstract
The traditional arc suppression method by grounding neutral point through arc suppression coil cannot meet the requirement of safe and stable operation for the power distribution network with solid insulated cables.In this paper,a technology for eliminating the arc grounding fault (arc-suppression,for short)based on fast switch is proposed,and the advantages of this technology are introduced.The principle of arc suppression and the corresponding fault identification,fault phase selection and fault line selection are discussed,and the action process of the arc-suppression device is described.Simulation verifies the feasibility of the arc suppression principleand the rationality of the action flow of the device.It is concluded that this arc suppression technology based on fast switch can quickly eliminate the arc grounding fault in theory and help improve the reliability of the distribution network.关键词
