[0002] Currently, Chinese utility model patent CN212392559U discloses a shockproof power distribution cabinet, relating to the field of power distribution cabinet technology. This shockproof power distribution cabinet includes a power distribution cabinet fixed to a support assembly. The support assembly is equipped with a shock-absorbing component and a ventilation component. The support assembly provides support for the power distribution cabinet, resulting in excellent stability. The shock-absorbing component provides excellent vibration damping. The ventilation component on the support plate provides ventilation and heat dissipation inside the power distribution cabinet, as well as removing dust, making it highly practical.

[0003] While existing distribution cabinets can improve ventilation by adding heat dissipation components, other problems still exist during use. For example, they lack flame extinguishing alarm functions. In cases of leakage, short circuits, overload, or excessive contact resistance, fires may occur. Due to the tight enclosure, it is difficult for personnel to detect and handle the fire in its initial stages, allowing it to spread and compromise safety. Furthermore, they lack wire harness clamping to prevent detachment. After installation, each module requires external wiring connected in series, resulting in unstable connections. Pulling on the external wires can easily cause them to detach or become loose, increasing the maintenance burden. To address these issues, we propose a distribution cabinet with flame extinguishing functionality. Utility Model Content

When a fire breaks out in the wiring or module inside the cabinet due to leakage, overload, or short circuit, the flame will affect and transmit to the flame extinguishing layer. Under the influence of the flame, the flame extinguishing layer will actively release flame extinguishing microcapsules to extinguish the fire. The smoke generated by the flame will be transmitted to the smoke sensor as it rises. After receiving the information, the smoke sensor will feed back to the internal controller and activate the audible and visual alarm. This allows the flame extinguishing alarm function to extinguish the internal flame in its nascent stage and can also prompt personnel to perform timely maintenance and repair, ensuring high safety.
