Step 1.5: associating the power failure meter box analyzed in the step 1.4 according to the equipment information in the user repair information, and if the power failure meter box is associated, generating a record of a fault work order; if the correlation is not available, no record is generated, and the fault location is finished.
6. The working method of the grid GIS visual emergency repair system according to claim 4, wherein in the emergency repair server, the fault location scheme matched with the ID number assigned to the power consumption information acquisition system is as follows:
step 2.1: associating each acquisition terminal device in the uploaded electric information acquisition system with a power failure device, and inquiring the type of the device from a device library, wherein if the device is a user electric energy meter device, the fault location is finished; if the equipment is distribution transformer equipment, entering step 2.2;
step 2.2: calling real-time voltage and current data of the transformer, and judging that the three phases are complete to be invalid faults if the current voltage exists; if no voltage current exists, the step 2.3 is carried out;
Step 2.3: step 2.2, judging a transformer without current voltage, deriving the line according to the topological connection of the line, associating the known power failure information accessed in the power distribution network fault positioning system with the line, and judging that the transformer is abnormal if the known power failure information is not associated with the line; if so, it is determined as a planned, temporary, or fault power outage and the process is terminated.
7. The working method of the grid GIS visual emergency repair system according to claim 4, characterized by further comprising: the 95598 system transmits the repair information of the user to an emergency repair server, and the emergency repair server obtains fault positioning information according to the repair information of the user.
8. the working method of the power grid GIS visual emergency repair system according to claim 4, wherein the on-site line patrol monitoring device transmits fault information of on-site line patrol detection to the emergency repair server, so as to obtain fault positioning information.
