Description

technical field [0001] The invention relates to the technical field of partial discharge electrification detection of electric power equipment, in particular to a partial discharge detection device based on unmanned aerial vehicle inspection. Background technique [0002] Partial discharge refers to the phenomenon that the discharge occurs in the local area of ​​the insulating medium without breakdown due to the uneven electric field or the concentration of the electric field, that is, the phenomenon that the discharge does not penetrate between the conductors to which the voltage is applied. Partial discharge may occur inside the insulating medium, on the interface of the insulating medium, and on the surface of the insulating medium. Carrying out partial discharge detection on equipment and discovering the discharge source early and accurately can prevent accidents and ensure the safe and reliable operation of the power system. [0003] At present, the partial discharge a...

Problems solved by technology

However, due to the topography and environment of our country, the overhead lines and base towers are mostly in the mountainous areas with complex environments and the wilderness environment is relatively harsh, and the overhead lines and base towers are prone to failure due to the adverse weather of the natural environment. Partial discharge detection of overhead lines and base towers is still vacant, and it is impossible to effectively and timely discover potential safety hazards in overhead lines and base towers, which poses a great threat to the safety and reliability of power system operation

[0004] At present, the traditional inspection of overhead lines and base towers mainly relies on human inspection methods, and manual inspection needs to consume a lot of financial, material and energy resources

Moreover, due to the overhead line and the geographical location of the base tower during manual inspections, it is impossible to accurately find the defects of the equipment, and it also poses a great threat to the personal safety of the staff during the inspection.

Therefore, the traditional inspection poses a huge threat to the safe operation of the power grid and the personal safety of the staff.
