Zusammenfassung:Against external force damage of transmission line has been a security problem need to be solved urgently. The paper analyzes the relationship between key characteristic quantity of line and the distribution regularities of spatial magnetic field by simulation, establishes dynamic mathematical model of the distance between vehicle manipulator and the high voltage wire, develops warning system against external forces of transmission line based on magnetic field measurement. Field test shows that through real-time measurement of the dynamic distance between vehicle manipulator and the high voltage wire, we can warn the external force damage accurately and timely, it provides an effective and reliable method to solve the trouble from external force damage of transmission line.
