The invention relates to a manufacturing method of a hot-line work technical training distributing line part 3D (three-dimensional) teaching video. The method includes: building scene, equipment, character, tool, management document material models, and building a management system which comprises model material library management software, dynamic control engine software, video recording software, video teaching editing software, a 3D animation management subsystem, a window interface GUI (graphical user interface) and a GUI interface generating tool; using the 3D animation technology to manufacture simulation animation courseware, using the 3D animation manufacturing technical and physical engine technology to manufacture an electric power animation material video, and using audio and video editing manners of the editing system to make standard operations, safety technical training and the like of an electric system into the 3D animation teaching video. The method has the advantages that the manufactured teaching video is visualized and vivid, long-term and sustainable, good in teaching effect and low in training cost.
