[0002] The integrated primary and secondary ring main unit (RMU) is an intelligent complete set of equipment that integrates primary and secondary equipment, primarily used in power supply systems. By combining the primary equipment (such as the ring main unit itself and high-precision sensors) with the secondary equipment (such as centralized DTUs), it achieves the goals of "reliability, miniaturization, platformization, versatility, and economy." The integrated primary and secondary ring main unit is widely used in power supply systems, especially in distribution networks requiring high reliability and intelligence. It can collect data such as active power, reactive power, power factor, and frequency, and has functions such as line loss metering, energy metering, and voltage over-limit alarms. It supports the transmission of short-circuit / ground fault events, meeting the needs of distribution network automation.
[0003] However, when the electrical components inside the existing integrated primary and secondary ring main units catch fire, the fire source inside the ring main unit cannot be extinguished quickly, resulting in severe damage to the inside of the ring main unit. At the same time, because the power department's maintenance personnel and firefighters cannot arrive at the scene in time to implement fire extinguishing and assistance measures, they cannot extinguish the fire inside the ring main unit from the outside.

[0028] like Figure 1 , Figure 2 and Figure 5As shown, an embodiment of the present invention provides a primary and secondary integrated ring network box, comprising a box body 1 and a fire extinguishing device. The box body 1 includes an installation frame 2 for placing primary and secondary equipment and two expansion frames 3. The two expansion frames 3 are detachably connected to both sides of the installation frame 2. A drying mechanism 4 is snapped onto the top of the installation frame 2, and a sealing structure 5 is provided between the bottom of the expansion frame 3 and the inner wall of the box body 1. The fire extinguishing device includes a fire extinguishing component 6 and a fixing frame 7 fixed inside the installation frame 2. A fire detector 8 is provided on the fixing frame 7. The fire extinguishing component 6 includes a control valve 61 electrically connected to the fire detector 8. The fire detector 8 has a smoke hole facing the inside of the installation frame 2.
[0029] The aforementioned integrated primary and secondary ring mesh enclosure, equipped with a drying mechanism 4, provides a dry environment inside the enclosure 1, preventing moisture from damaging the primary and secondary equipment inside the enclosure 1 and effectively avoiding electrical faults or even fire hazards. The sealing structure 5 effectively prevents moisture and humidity from entering the enclosure 1, preventing damage to the primary and secondary equipment from dampness, and also prevents insects and other small particles from entering the enclosure 1, keeping the interior clean. The fire detector 8 is installed to detect fires in their early stages and activate the control valve 61 to start the fire extinguishing assembly 6 for timely fire suppression. The fire detector 8 is sensitive to smoke particles; when smoke is generated in the early stages of a fire, it can penetrate through the smoke hole to the internal components of the fire detector 8 for detection.
[0030] In addition, fire detector 8 can also monitor characteristic quantities such as temperature, smoke, gas, and radiation intensity in the internal environment of enclosure 1, and convert these physical quantities into electrical signals to send alarm signals. This is existing technology and will not be elaborated further.
[0031] like Figure 2 As shown, in one embodiment, the mounting frame 2 and the expansion frame 3 are fixed together by bolts. Each side frame of the mounting frame 2 has a protruding snap-fit block 21, and the side wall of the expansion frame 3 has a snap-fit groove 31 for the snap-fit block 21 to be inserted into. This increases the stability of the connection between the mounting frame 2 and the expansion frame 3.
[0032] like Figure 2 As shown, in one embodiment, the interior of the mounting frame 2 is interconnected with the interior of the expansion frame 3. Both the mounting frame 2 and the expansion frame 3 are equipped with a placement rack 9, which has multiple threaded holes. This facilitates the assembly and disassembly of the primary and secondary equipment.
[0033] like Figure 1 and Figure 2As shown, in one embodiment, the mounting frame 2 has a fitting groove 22 at its top; the drying mechanism 4 includes a fitting platform 41, a housing 42, and a drying fan 43. The fitting platform 41 is snapped into the fitting groove 22, and the housing 42 is fixedly installed on the fitting platform 41. An air outlet 421 is provided at the top of the housing 42, and the drying fan 43 is installed inside the housing 42 and connected to the bottom of the air outlet 421. The fitting platform 41 facilitates the installation and positioning of the drying mechanism 4 and also makes it easier for maintenance personnel to disassemble and repair the drying mechanism 4.
[0034] In one embodiment, the fitting platform 41 has a communication port, and the interior of the housing 42 is connected to the interior of the mounting frame 2 through the communication port. The air suction direction of the drying fan 43 is towards the communication port.
[0035] like Figure 2 and Figure 4 As shown, in one embodiment, the drying fan 43 includes a front impeller 431 and a rear impeller 432. Blades 433 are welded between the surfaces of the front impeller 431 and the rear impeller 432. Liners 434 are provided on the blades 433 and at the welded joints between the blades 433 and the front impeller 431 and the rear impeller 432. The air outlet 421 is connected to the front impeller 431 by an arc transition. The blades 433 are welded between the surfaces of the front impeller 431 and the rear impeller 432 to improve airflow stability and reduce material adhesion to the blades 433. Liners 434 are provided on the blades 433 and at the welded joints between the blades 433 and the front impeller 431 and the rear impeller 432. The liners 434 are fixed to the blades 433 by countersunk screws for easy periodic replacement.
[0036] Specifically, the front impeller 431 is trumpet-shaped, which helps to increase the airflow pressure at the outlet 421.
[0037] like Figure 2 and Figure 3 As shown, in one embodiment, the bottom of the expansion frame 3 has a protruding hook portion 32, and a water collection chamber is formed between the hook portion 32 and the inner wall of the housing 1. The contact area between the hook portion 32 and the inner wall of the housing 1 is filled with a sealing structure 5, which is a sealing strip. This can prevent moisture and humidity from entering the interior of the housing 1 and simultaneously isolate moisture and humidity in the water collection chamber, effectively preventing primary and secondary equipment from being damaged by moisture.
[0038] like Figure 5 As shown, in one embodiment, the fixing frame 7 is sequentially threaded with a first disassembly seat 71 and a second disassembly seat 72. The second disassembly seat 72 is provided with a limiting ring 73, and a limiting space is formed between the limiting ring 73 and the second disassembly seat 72.
[0039] like Figure 2 and Figure 5As shown, in one embodiment, the fire extinguishing assembly 6 includes a connecting pipe 62, a nozzle 63, and a cylinder 64 inserted into a limiting space. A control valve 61 is disposed between one end of the connecting pipe 62 and the cylinder 64. The connecting pipe 62 is mounted on one side of the fixing frame 7, and the nozzle 63 is installed on the other end of the connecting pipe 62. The nozzle 63 has multiple spray holes 631. Thus, the cylinder 64 facilitates the storage of the extinguishing agent; the spray holes 631 allow for precise control of the extinguishing agent's spray range. By adjusting the size and distribution of the spray holes 631, the extinguishing agent is ensured to be evenly sprayed onto the fire source, thereby improving the accuracy of fire extinguishing and avoiding waste. Furthermore, the design of the spray holes 631 helps to evenly disperse the extinguishing agent over a larger area, rapidly reducing the temperature around the fire source, significantly improving fire extinguishing efficiency. The extinguishing agent forms a finer mist during spraying, increasing the contact area with the flame and accelerating flame extinguishing.
[0040] like Figure 5 and Figure 6 As shown, in one embodiment, the fire detector 8 includes a housing 81, a control module 82, and a smoke sensor 83. The housing 81 is detachably fixed to a first mounting base 71. The control module 82 and the smoke sensor 83 are both installed inside the housing 81. One end of the control module 82 is communicatively connected to the smoke sensor 83, and the other end of the control module 82 is electrically connected to a control valve 61. The smoke sensor 83 is located at the smoke vent. When smoke is generated in the early stage of a fire and detected by the smoke sensor 83, the control module 82 receives the information and converts it into an electrical signal to control the opening and closing state of the control valve 61, thereby extinguishing the fire source inside the housing 1.
[0041] Preferably, the smoke sensor 83 can be of model MQ-2.
[0042] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
[0043] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
