Abstract

Abstract: To better understand the process of fire caused by energized wires, combining the basic theory of wire ignition with experimental research, analyzed from three aspects: (1) Experimental research and mechanism analysis of wire ignition and flame spread under the condition of external radiation source heating; (2) The influence of external environmental conditions such as the influence of pressure, oxygen concentration, and gravity on the combustion behavior of the wire; (3) In-depth discussions on the numerical simulation research of energized conductors, analysis of the challenges and problems faced by current conductor fire research, and the basic development direction of future overcurrent conductor combustion research. The results can give references for research and design of fire-resistant wire.
