Geräte zur thermischen Abschaltung mit mechanischem Widerstand (DF SF-Serie 10 Ampere)

SF DF Series thermal cutoff assembly and equipment. The thermal cutoff assembly includes: a thermal cutoff connected to a DC circuit. The thermal cutoff is connected in parallel with a capacitor or a capacitor loop, which is formed by a plurality of capacitors connected in series. The capacitance of the capacitor or the total capacitance of the capacitor loop satisfies the following conditions: at the moment when the thermal cutoff is disconnected, the DC circuit charges a capacitor or a capacitor loop. Anschließend, die Spannung zwischen den Kontakten der thermischen Abschaltung und dem Gleichstromkreis steigt an, um sicherzustellen, dass der Gleichstromkreis getrennt wird. Durch die vorliegende Erfindung, Das Problem, dass die thermische Abschaltung im Gleichstromkreis den Stromkreis nicht effektiv unterbrechen kann, ist gelöst, und der Effekt der Verbesserung der Schaltungssicherheit wird erreicht.
