Introduction and Advantage Analysis of Helicopter Inspection Separation Technology in UHV Transmission Line Inspection

As one of the new technologies applied in helicopter inspection of transmission lines, inspection separation technology has great advantages over traditional helicopter inspection methods in terms of operation efficiency, defect detection rate and achievement category. It is the development direction of helicopter inspection of transmission lines. This paper introduces the inspection separation technology, and analyzes the main advantages of the inspection separation technology through the comparative analysis of the operation technical indexes before and after the application of the inspection separation technology by the State Grid General Aviation. Combined with the inspection demand of the transmission line helicopter, the application prospect of the inspection separation technology is prospected.
