Problems solved by technology

[0003] Due to the poor air circulation in the room, in the high temperature weather in summer, the external temperature plus the heat generated by the electronic components in the power distribution cabinet will cause the temperature in the power distribution cabinet to rise sharply, and it is easy to occur in the power distribution cabinet. Fire, and when a fire occurs due to poor air circulation, the combustibles in the power distribution cabinet will not be fully combusted, and a large amount of carbon monoxide will be generated. At this time, the carbon monoxide in the power distribution cabinet will erupt instantly, which will cause the staff to inhale a large amount of carbon monoxide, which will endanger the health of the staff.

Embodiment 1

[0022]ReferenceFigure 1-3, A self-extinguishing indoor power distribution cabinet in the event of a fire, including a cabinet body 1, a plurality of heat dissipation holes 2 are opened on the inner wall of the cabinet body 1, a circular slot 3 is opened on the top of the cabinet body 1, and a fan is fixedly connected to the inner wall of the circular slot 3 4. The lower end of the cabinet 1 is provided with a reaction chamber 5, and the inner wall of the reaction chamber 5 is fixedly connected with a reaction plate 6. The reaction plate 6 is made of ferric oxide material. It should be noted that the reaction plate 6 will react with carbon monoxide at high temperatures , The reaction equation is: 3CO+Fe2O3=2Fe+3CO2(High temperature), the inner wall of the circular groove 3 is connected with the inner wall of the reaction chamber 5 through the air inlet pipe 7, and the top of the reaction chamber 5 is provided with an air outlet 8;

[0023]The inner wall of the cabinet 1 is symmetrically...

Embodiment 2

[0029]ReferenceFigure 4 The difference from the first embodiment is that a permanent magnet block 18 is fixedly connected to the top of the circular groove 3, and a lead frame 19 is inserted into the side wall of the permanent magnet block 18. An impeller in the fan 4 is made of magnetic material, and the lead frame 19 It is coupled to the battery 13.

[0030]In this embodiment, when the fan 4 rotates, the impeller made of magnetic material continuously sweeps the permanent magnet block 18, and the lead frame 19 continuously cuts the magnetic induction line between the permanent magnet block 18 and the impeller, and the lead frame 19 generates The current is induced to supply power to the storage battery 13, so that the power in the storage battery 13 is kept sufficient, the number of replacements of the storage battery 13 is reduced, and its service life is prolonged.

Abstract

The invention discloses a self-extinguishing indoor power distribution cabinet in case of fire, which comprises a cabinet body, a plurality of heat dissipation holes are formed in the inner wall of the cabinet body, a circular groove is formed in the top in the cabinet body, a fan is fixedly connected to the inner wall of the circular groove, a reaction cavity is formed in the lower end of the cabinet body, and a reaction plate is fixedly connected to the inner wall of the reaction cavity. The reaction plate is made of an iron trioxide material, the inner wall of the circular groove is connected with the inner wall of the reaction cavity through an air inlet pipe, an air outlet is formed in the top in the reaction cavity, and sliding plates are symmetrically connected to the inner wall ofthe cabinet body in a sliding mode. A large amount of carbon monoxide in the cabinet body can be guided into the reaction cavity through rotation of the fan, so that the reaction plate reacts with thecarbon monoxide at high temperature to generate iron and carbon dioxide, and the carbon dioxide flows out through the air outlet, so that the concentration of the carbon dioxide in the cabinet body is increased, and fire in the cabinet body is inhibited; and meanwhile, the harm to the body health of workers due to over-high carbon monoxide concentration in the cabinet body is avoided.

Description

Technical field[0001]The invention relates to the technical field of electrical equipment, in particular to a self-extinguishing indoor power distribution cabinet when a fire occurs.Background technique[0002]The indoor power distribution cabinet is used for power distribution and control in the indoor power supply system. Power distribution equipment for metering and connecting cables.[0003]Due to the poor indoor air circulation, in the high temperature weather in summer, the temperature of the outside and the heat generated by the electronic components in the power distribution cabinet will cause the temperature in the power distribution cabinet to rise sharply, and it is easy to occur in the power distribution cabinet. Fire, and in the event of a fire, due to poor air circulation, the combustion in the power distribution cabinet is not fully burned, and a large amount of carbon monoxide will be generated. When the staff is warned to extinguish the cabinet, open the cabinet door At...
