Description

technical field [0001] The invention relates to the technical field of line inspection of a low-voltage distribution network, in particular to a line inspection device for a low-voltage distribution network. Background technique [0002] The low-voltage distribution network is an important part of the power grid, and it is also a part closely connected with the user side. As the current smart grid continues to improve and various parts become more and more intelligent, the development of the low-voltage distribution network needs to be optimized, especially When a disconnection fault occurs in the low-voltage distribution network, most of the time, the line inspectors manually inspect the entire line, which is time-consuming and laborious. This not only causes unnecessary waste of human resources, but also delays the time for troubleshooting. Huge losses have been caused to the power grid and the people. Aiming at the aspect of intelligent identification of power grid fault...

[0002] The low-voltage distribution network is an important part of the power grid, and it is also a part that is closely connected with the user side. As the smart grid continues to improve and various parts become more and more intelligent, the development of the low-voltage distribution network needs to be optimized, especially When a disconnection fault occurs in the low-voltage distribution network, most of the time, the line inspectors manually inspect the entire line, which is time-consuming and laborious. This not only causes unnecessary waste of human resources, but also delays the time for troubleshooting. Huge losses have been caused to the power grid and the people

Aiming at the intelligent identification of power grid faults, people continue to conduct research. The Chinese patent application number 2015100111691 discloses an automatic fault detection system for power lines. The system uses a groove hole composed of an upper groove and a lower groove to pass through The power line is fixed on the power line. The disadvantage is that when the power line breaks, the system will fall to the ground due to gravity, causing a certain loss, and the system cannot detect the zero line break fault. analyze
