[0002] An electrical cabinet is an enclosed box used to install and manage electrical equipment. It plays an important role in power systems and industrial automation. It distributes power to different circuits and devices. It contains various switches, circuit breakers, relays, and controllers required to control the circuits. The electrical cabinet is equipped with protective devices such as fuses, overload protectors, and leakage protectors to prevent electrical faults and short circuits.

[0003] There are many electrical equipment and wires inside the electrical cabinet, and high temperatures are likely to occur inside during use. When a traditional automatic fire extinguishing device is triggered, the fire extinguishing material it sprays will be discharged through the heat dissipation holes on the electrical cabinet. The contact between the heat dissipation holes and the outside world will affect the fire extinguishing effect of the fire extinguishing equipment.

[0004] Therefore, those skilled in the art have proposed an automatic fire extinguishing device for an electrical cabinet to solve the problems raised in the background art.

[0005] The above information disclosed in this background technology is only used to increase the understanding of the background technology of the present invention.
