Abstract

The invention discloses a medium-voltage distribution network fault quick positioning device in the field of power equipment. The medium-voltage distribution network fault quick positioning device comprises a monitoring front end, a monitoring background and a power supply module. The monitoring front end includes a data acquisition module, a data processing module and a data transmission module.The monitoring background includes a server and a computer system. The output end of the data acquisition module is connected to the data transmission module via the data processing module. The data transmission module is connected to the monitoring background. The power supply module supplies power to the monitoring front end and the monitoring background. The medium-voltage distribution networkfault quick positioning device solves a problem that a traditional distribution network fault location method is low in accuracy, low in reliability and complex, and inefficient in time, and can be used for distribution network monitoring.

Description

technical field [0001] The invention relates to a distribution network fault location technology, in particular to a distribution network fault fast location device and location method. Background technique [0002] The distribution network directly operates in a complex natural environment, and various faults cannot be avoided. When a fault occurs in the distribution network, in order to improve the safety and reliability of the distribution network and minimize the damage to the power system, it is necessary to eliminate the fault in time to reduce the scope of power outages, and the rapid and accurate location of the fault point is the key to timely troubleshooting premise. [0003] The distribution network topology is complex and has many branches, and its fault location has always been a difficult point. In the past, the manual line troubleshooting method had a large workload and took a long time, which could easily lead to failure to restore power supply in a short p...
