The invention discloses a line fault positioning system for a 10kV power distribution network, and relates to the technical field of power grid fault detection. The line fault positioning system for the 10kV power distribution network comprises a thunder and lightning detection subsystem, a fault early warning module and a line fault positioning subsystem, and by introducing the thunder and lightning detection subsystem, the fault early warning module and the line fault positioning subsystem, the system can detect thunder and lightning current, give out fault early warning and position fault points through computational logic. The method is advantaged in that improvement of fault positioning accuracy is facilitated, maintenance personnel can rapidly and accurately find problems, a logic for determining the faults caused by lightning strike and a method for calculating the strike distance are introduced, the faults caused by lightning strike can be accurately positioned, maintenance cost is reduced, and mainte
