A two-way wireless communication power distribution fault detection system

technical field

The utility model discloses a two-way wireless communication power distribution fault detection system, which belongs to the technical field of distribution network fault detection.

Background technique

The distribution network is directly connected to the users, and its reliable power supply capacity and power supply quality directly affect the lives of users. Therefore, the automation of the distribution network has become an extremely urgent task, and it has attracted more and more attention. Complex, if there is a fault in the line, it will take a lot of manpower, material resources and time to find out the specific location of the fault; there are more and more researches on fault location, and there are also molded products to provide, but most of them are not highly intelligent and still Manual search is required; at present, there is also a system that sends information back to the background through GSM, combined with GIS for accurate fault location. But this kind of fault location system is one-way, always when a fault occurs, the fault indicator turns over and then sends data to the receiving front end, and then the background process, but the actual situation of the fault indicator can not always be well grasped, it is easy It will not be able to locate accurately because of the failure of the fault indicator or insufficient power supply.

Utility model content
