Web24 jan. 2024 · Of the three types, off-gas detectors displayed the highest sensitivity and accuracy. They averaged less than 10 seconds’ response time after off-gassing started and 6 minutes 11 seconds before thermal runaway commenced. Neither the LEL nor voltage sensors activated until after thermal runaway had initiated. Some electronic components develop lower resistances or lower triggering voltages (for nonlinear resistances) as their internal temperature increases. If circuit conditions cause markedly increased current flow in these situations, increased power dissipation may raise the temperature further by Joule heating. A vicious circle or positive feedback effect of thermal runaway can cause failure, sometimes in a spectacular fashion (e.g. electrical explosion or fire). To prevent these hazards, …
