Therefore, the safe use and fire prevention of distribution cabinets and boxes are particularly important. Therefore, more and more fireproof distribution cabinets are entering people's lives.

[0003] In the Chinese patent with publication number CN210443890U, a power distribution cabinet capable of automatic fire extinguishing is disclosed. The patent has the advantages of good heat dissipation effect, automatic isolation and positioning of the fire location, high fire extinguishing efficiency, and effective prevention of fire spread. However, when extinguishing a fire, the above-mentioned power distribution cabinet capable of automatic fire extinguishing uses a smoke detector and an infrared temperature detector to confirm the fire situation in the workroom where the fire occurs, and then it is necessary to drive the fire extinguishing parts to move through the guide rails. As a result, when extinguishing a fire, the fire extinguishing parts are slow to start and extinguish the fire, and it is difficult to actively extinguish the fire and give early warning before the electrical parts catch fire. Therefore, we propose an automatic fire extinguishing system for a power distribution cabinet. Utility Model Content

[0021] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0022] The utility model provides Figure 1 An automatic fire extinguishing system for a power distribution cabinet is shown, comprising:

[0023] The cabinet body 1 has a cabinet door 2 on one side thereof, the cabinet door 2 is provided with an observation window 3 for observing the cabinet body 1, and the cabinet door 2 is also provided with a signboard 4 for warning people, and the signboard 4 is provided with a plurality of exhaust holes.

[0024] As can be seen from the above, when in use, open the cabinet door 2, put the electrical components to be installed into the cabinet 1, observe the electrical components inside the cabinet 1 through the observation window 3, and release the heat generated inside the cabinet 1 through the ventilation holes on the signboard 4.

[0025] refer to Figure 1-Figure 3 As shown, the middle part of the cabinet 1 is recessed inward to form a cavity, and a fire extinguishing device is arranged inside the cavity. The fire extinguishing device includes a monitoring component, a fire extinguishing component and an information transmission component. The monitoring component includes a flame detector 5 arranged on the inner wall of the cavity and a plurality of temperature detectors 7 arranged on the inner wall of the cavity.

The flame detector 5 can detect the spark and flame information of the distribution cabinet in real time, and transmit the alarm information to the controller 9. The temperature detector 7 can detect the temperature inside the distribution cabinet in real time.

[0027] The fire extinguishing assembly includes two fire extinguishing boxes 10 arranged in the cavity. The two fire extinguishing boxes 10 are respectively arranged in the upper half of the cavity and the lower half of the cavity. The fire extinguishing boxes 10 are controlled by the controller 9. When the controller 9 sends out a fire extinguishing signal, the fire extinguishing box 10 releases the fire extinguishing agent to extinguish the fire.

[0029] By adopting the above technical solution:

[0030] When the temperature of an electrical component is too high, the temperature of the electrical equipment will have a heating process. After the temperature detector 7 calculates the temperature inside the cabinet and transmits it to the controller 9, the controller 9 can collect and calculate the heating rate and danger level inside the cabinet 1. By setting the alarm threshold, it can issue a warning before the distribution cabinet catches fire. When a fire occurs, there will be high temperature, smoke, sparks and other characteristics. The cabinet door 2 can quickly identify the fire site, and the fire extinguishing box 10 is used to extinguish the fire through the controller 9. At the same time, the fire extinguishing box 10 can also trigger the fire extinguishing agent to take effect through the temperature sensing start mode, and quickly produce a large amount of sub-nanometer solid phase particles and inert gas mixtures, which act on every corner of the fire in a high-concentration smoke-like three-dimensional full-flooding manner. Through physical cooling, chemical inhibition, and oxygen dilution, the fire can be quickly and efficiently extinguished. At the same time, the controller 9 can also transmit the collected data to the cloud platform through the 4G module, and multiple terminal devices can access and set the control system through the cloud platform software.
