AI Technical Summary
When the internal components of the existing high-voltage distribution cabinets are short-circuited and overheated or fired, they cannot effectively extinguish the fire, which may lead to greater losses.
A high-voltage distribution cabinet containing dry powder fire extinguishing agent packs and dry ice packs was designed to generate pressure through gasification and expansion of dry ice packs, and the dry powder sprayed from the dry powder fire extinguishing agent packs was extinguished to achieve internal fire, and through heat dissipation holes and shielding nets. The structure ensures safe heat dissipation and prevents water droplets from entering.
In the case of short-circuit fire, the fire is effectively extinguished, the loss is reduced, and the normal heat dissipation and safety inside the distribution box is ensured through the design of the heat dissipation hole and shielding net.
