Abstract
Description
technical field
[0001] The invention relates to the fields of magnetic heating materials and safe operation of power grids, in particular to a ferrite-based anti-icing composite coil for transmission line conductors and a preparation method thereof. Background technique
[0002] Due to the hazards of winter ice and snow on power transmission lines, it is easy to cause serious disconnection, tower collapse, large-scale power outages, power cuts and other accidents. It not only poses a serious threat to the safe operation of my country's power system, but also has always been a difficult problem to be solved urgently in the research of power system. At present, dozens of anti-icing and anti-icing methods have been researched and applied at home and abroad. Among them, the anti-icing technology of magnetic materials with low Curie point temperature is used, because it has the characteristics of automatic anti-icing with temperature changes, which has attracted great attention. ...
