Technology Research Of Helicopter In Patrol Of Transmission Lines

This dissertation is research in the power grid operation and maintenance technique of helicopter. Analyze the key problems of inspection method, water resistance, washing method and hotline maintenance technology respectively. Enhance the power line service level by inventing the brand new technique of power grid operation and maintenance, such as helicopter inspection, helicopter hotline washing and helicopter hotline maintenance. Helicopter hotline maintenance is based on helicopter inspection and helicopter washing technique, and it's developed as a new electric transmission line maintenance and maintenance method according to the equal potential principle. The helicopter sends linemen to the work place directly or by using the suspension cable indirectly. The key points are including the selection of helicopter, the research of maintenance method and the exploitation of tools. Compare with the traditional method of maintenance, the application of helicopter is not only enhances the working efficiency, but also conquers the limit of topography. It will improve the maintenance and operational level of EHV/UHV power transmission line by using the helicopter.
