Abstract
Fault of DC loop network is common in 35 kV substations. The potential hazards of faults are discussed, the faults are classified and their mechanism is analyzed, and the methods of their troubleshooting are described in detail. Research shows that fault of DC loop network restricts the normal operation of the substation or even the power grid; co-polar operation and misconduct of change in secondary circuit are the two common causes of such failures; combined with mechanism comparison and analysis before and after the transformation of the power grid, and the use of devices such as portable grounding fault locator of DC system, are powerful tools for the troubleshooting of the fault. These conclusions lay the theoretical foundation for the resolution of faults of DC loop network in 35 kV substations.关键词
