Shutters 5 are installed on both sides and the front of the air inlet box 4. A cooling fan 6 is installed on the top of the air inlet box 4. A grille plate 7 is installed near the bottom of the cabinet 1. A fire extinguishing agent bottle 9 is installed on the top of the heat dissipation box 8, and an electromagnetic control valve 10 is installed at one end of the fire extinguishing agent bottle 9. A conduit 11 is installed at the bottom of the electromagnetic control valve 10 and passes through the interior of the cabinet 1 near the top. A screw 12 is movably installed on one side of the interior of the cabinet 1 near the front end. A motor 13 is installed at the top of the screw 12 and located on the top of the heat sink 8. A lifting block 14 is movably installed on the periphery of the screw 12. A spray head 15 is installed on one side of the lifting block 14. A connecting pipe 16 is connected between the spray head 15 and the conduit 11. The interior of the cabinet 1 is used to install electrical components and smoke sensors, and the smoke sensors are used to monitor whether the electrical components inside the cabinet 1 are abnormal.

[0022] In this embodiment, the interior of the cabinet 1 and the air inlet box 4 are interconnected, and a heat dissipation groove is opened between the cabinet 1 and the heat dissipation box 8. External air enters the interior of the air inlet box 4 through the shutter 5 and is blown into the cabinet 1 through the heat dissipation fan 6 for heat dissipation.

[0023] In this embodiment, the spraying direction of the spray head 15 is tilted backward, and the lifting block 14 is sleeved on the outer periphery of the screw 12 and is threadedly connected. The spray head 15 is located at different heights by lifting and lowering the lifting block 14, and dry powder is sprayed on electrical components at different positions to extinguish the fire.
