AI Technical Summary
Existing fire extinguishing devices in distribution boxes rely on heat-sensing equipment. If the electronic equipment fails to function properly, the fire extinguisher switch may not be triggered, thus missing the best opportunity to extinguish the fire.
The sliding plate loses its traction force through the metal wire melting mechanism, and moves upward to press the movable contact, triggering the controller to open the solenoid valve and activate the fire extinguisher.
It enables automatic activation of the fire extinguisher when the temperature inside the distribution cabinet rises, avoiding missing the best time to extinguish the fire and protecting the equipment safety.
