Networking ring main unit fault indication system based on redundancy technology

Abstract

The invention discloses a networking ring main unit fault indication system based on a redundancy technology. The networking ring main unit fault indication system comprises a front end and a background which are in communication connection. The background comprises a command center, a mobile patrol module and a data storage server which are in communication connection with one another; the front end comprises a plurality of ring main unit fault indication modules, the ring main unit fault indication modules receive information of adjacent ring main unit fault indication modules, and the ring main unit fault indication modules send the received information and information of the ring main unit fault indication modules to the background together; each ring main unit fault indication module comprises a plurality of interval fault indication modules, and any node interval is detected by two interval fault indication modules. According to the invention, by utilizing multiple designs of a redundancy technology, two different ring main unit fault indication systems are adopted for simultaneous detection for the same interval node, so that fault information false alarm and error alarm caused by self fault reasons of the ring main unit are reduced, and manpower and time are saved.

Description

technical field

[0001] The invention relates to the field of faults of ring network cabinets, in particular to a fault indication system of networked ring network cabinets based on redundancy technology. Background technique

[0002] With the development of society, power users have higher and higher requirements for power supply reliability. Due to external damage, equipment aging and other reasons, power equipment failures still occur from time to time. It is an urgent need for people to restore power supply as soon as possible after a failure. When a cable fault occurs, the main means of auxiliary fault finding is that personnel go to the site to check the fault indicator signal on the ring network cabinet, analyze and judge multiple signals, lock the fault range, and conduct a key inspection of the range until the fault point is found Carry out emergency repair work at the location. Due to the fact that the fault indicator signal cannot be sent far away, the fault loca...
