AI Technical Summary
⚠Technical Problem
In circuit breaking devices, the generation of electric arcs makes it impossible to quickly cut off the circuit, and existing technologies are unable to quickly extinguish the arc.
⚗Method used
The structure includes a first emitter and a second emitter. The first emitter receives energy from the igniter to cut off the cut-off portion from the conductor sheet. The second emitter presses the cut-off portion into the cooling component of the arc-extinguishing area, and the cooling component is used to quickly extinguish the arc.
🎯Benefits of technology
It enables rapid arc extinguishing, ensuring that the circuit can be quickly cut off and avoiding the continued impact of the arc.
