In modern power networks

distribution lines are widely distributed and complex

often crossing mountains

forests

rivers and other terrain. Traditional manual inspection is not only inefficient and long-cycled

but also difficult to detect hidden faults

making it more difficult to carry out work in extreme weather. With the characteristics of flexibility and efficiency

UAV technology brings new solutions for distribution line patrol and fault handling. This paper focuses on the research of the patrol and fault handling of distribution lines based on UAV technology

analyzes the technical advantages of UAVs in the patrol of distribution lines

and discusses the operation process

fault detection and identification methods and fault handling strategies

aiming to improve the efficiency and fault handling ability of distribution line patrol and ensure the safe and stable operation of the power system.
