摘要
分析超级电容火灾发生机理,进行模拟实验,探究超级电容在高温和过充条件下的安全特性。设计实验系统,调节加热器的电功率为2kW,使温度保持在200℃左右进行加热实验;设置充电电流为10A进行过充实验。分析实验过程中烟颗粒、可燃气体、温度、电压随时间的变化,通过监控这些特征参量可以为判断超级电容是否处于安全状态提供依据。
The mechanism of super capacitor fires was analyzed and simulated experiments were carried out to explore the super capacitor＇s security features under the condition of high temperature and overcharge. The experiment system was designed and the high temperature experiments were carried out at about 200 ℃ with electric power of 2 kW by heater. The overcharge experiments were carried out with 10 A of charge current. The changes of smoke, combustible gas, temperature and voltage with time during the experiments were analyzed. By monitoring the characteristic parameters, it provides reliable information to determine whether super capacitor is in a safe state.
