1.In calefactive phase, the electro thermal model of hot bridge wire was established, the calefactive time of invariable current fire case and capacitance discharge fire case were both studied.
在温阶段建热温模型,分别求解恒定流温时间和容放温时间。
2.Thermal ignition temperature was defined,the thermal ignition process of electric hot wire initiating devices was divided as calefactive phase and explosion phase.
