Reflecting on the actual needs of current disaster prevention and reduction work for transmission lines, and based on the existing distribution maps of pollution areas, lightning areas, wind areas, ice areas, and galloping areas, using the spatial analysis tools of GIS, an automatic verification platform for disaster prevention capability of transmission lines is developed. This platform utilizes transmission line account data and online monitoring data to automatically verify whether the pollution prevention, lightning prevention, wind prevention, ice prevention, and galloping prevention capabilities of transmission lines are reasonable. It provides renovation suggestions for unreasonable towers, and the results are used in production practice to guide design, maintenance, and differentiated disaster prevention work.
