Abstract 10kV distribution network in small current ground systematically feed line single-phase grounding fault isolation and location solution is nearly 30 years the focus of domestic and international industry experts to study, especially the grounding system single-phase grounding fault isolation and location solution is always the focus of the research at home and abroad arc suppression coil extinction. Combined with the characteristics of domestic 10kV distribution network construction, put forward a based on DC injection method of a new type of small current grounding fault isolation and location of online solutions and scheme research results show that the scheme can automatic isolation and locate the fault point, can reliably solve 10kV complete feed line in small current grounding fault isolation and location problem, can improve the distribution network earthing fault processing reliability, fast healing, is also able to meet the practical requirements of the distribution network construction of our country.
