Low-voltage fault discrimination system

The utility model discloses a low-voltage fault discrimination system, which comprises an acquisition module, a plurality of collection modules and a judgment module, wherein the acquisition module isused for detecting short circuit and grounding fault information of a low-voltage line and sending the fault information; the collection module is used for checking and processing the received faultinformation and then repackaging and transmitting the fault information to the judgment module; and the judgment module judges the position of the fault point and the fault state of the line accordingto the topological structure of the power distribution network in combination with a logic algorithm of the judgment module. According to the low-voltage fault discrimination system provided by the utility model, the fault information is judged after fault detection and collection when the low-voltage line of the distribution network breaks down, so that the fault point can be positioned more accurately, and maintenance pe
