<p>An ice-melting device for bundle conductor transmission line and thereof method. The tensile resistance section in the transmission line uses multi-bundle conductors, multi sub-conductors (3, 4, 5) of the bundle conductor are insulated with each other, so as to form multi independent current loops. The ice-melting device includes current transfer switches (7) which are provided on the two ends of the tensile resistance section and guiding current plates (6) among the sub-conductors (3, 4, 5). When the tensile resistance section is ice coating, the current transfer switches (7) which are provided on the two ends of the tensile resistance are turned off, and the connecting relation of the sub-conductors (3, 4, 5) is changed from parallel into series via the guiding current plates (6), and then the current in each sub-conductor increases up to the sum of the original current in all the sub-conductors, so as to realize ice-melting or line protecting for the conductor of the ice coating tensile resistance section in the transmission line.</p> |
