The invention relates to a method for testing operating parameters in breakage of a copper wire of electric transmission and transformation equipment. The method includes steps of sampling from practical burnout equipment, selection of an intact wire of identical specification and preparation into a high-temperature simulation sample, Gleeble tensile experiment at different temperatures, metallographic analysis on fractures of a practical broken wire and a broken wire pulled by GLEEBLE, SEM analysis on the fractures of the practical broken wire and the broken wire pulled by GLEEBLE, TEM analysis on the fractures of the practical broken wire and the broken wire pulled by GLEEBLE, and the like. High cost of destructive tests of practical power transmission and transformation equipment underseries parameters is avoided, most approximate operating parameters in breakage instantaneity in operation can be obtained, and accordingly effective criterions can be provided for accident analysis. 本发明涉及种输变电设备铜导线断裂时运行参数的测试方
