[0030] In this document, relational terms such as "first" and "second" are used merely to distinguish one entity or operation from another, without necessarily requiring or implying any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. The present invention will now be further described in conjunction with the accompanying drawings and embodiments:

[0031] Please see Figure 1-7 A novel intelligent power distribution box includes a box body 1. The box body 1 is equipped with an incoming line unit 2, a metering unit 5, a feeder unit 7, a branch outgoing line unit 3, a street light unit 4, and an emergency power interface 8. The incoming line unit 2 is electrically connected to the input terminal of the feeder unit 7 through a power distribution busbar. The output terminal of the feeder unit 7 is electrically connected to the branch outgoing line unit 3 and the street light unit 4 respectively. The emergency power interface 8 is electrically connected to the input terminal of the power distribution busbar through a copper busbar.

[0032] The incoming line unit 2 connects to the feeder unit 7 via the distribution busbar, and then branches to the outgoing line unit 3 and street light unit 4, forming an orderly power supply link. This improves space utilization and facilitates maintenance. The emergency power interface 8 is directly connected to the distribution busbar via a copper busbar, allowing for rapid connection to emergency power in case of main power failure. This ensures efficient emergency response and prioritizes power supply to street light unit 4 and critical loads, minimizing the impact of power outages. Each unit operates independently yet collaboratively, preventing a single fault from affecting the entire system. This ensures high power supply reliability. The independent power supply to street light unit 4 ensures stable emergency lighting and stable lighting in evacuation routes, enhancing electrical safety.

[0033] In some embodiments, the incoming line unit 2 includes a disconnecting switch, which is fixed on the mounting plate on the right side of the enclosure 1. The disconnecting switch is electrically connected to the input terminal of the feeder unit through the power distribution busbar. An incoming line port 10 is provided on the lower front side of the right side panel of the enclosure 1. The low-voltage side of the transformer is connected to the disconnecting switch inside the enclosure 1 through an incoming line cable.

[0034] The isolating switch is fixed to the mounting plate on the right side of enclosure 1, resulting in a compact and stable layout that improves the reliability of circuit control.

The low-voltage side of the transformer is directly connected to the isolating switch via an incoming cable, improving power transmission efficiency. Simultaneously, in conjunction with the isolating switch's on / off control, power can be quickly cut off during maintenance, ensuring operational safety.

[0035] In some embodiments, the feeder unit 7 includes four circuit breakers. The input terminals of the circuit breakers are electrically connected to disconnect switches via distribution busbars, and the output terminals of the circuit breakers are electrically connected to branch line unit 3 and street light unit 4, respectively. Outgoing ports 11 are provided on the lower rear side of the right side panel and the lower side of the left side panel of the enclosure 1. The branch line unit 3 is connected to the load after exiting the enclosure 1 via an outgoing cable from the outgoing port 11.

[0036] By configuring four circuit breakers in feeder unit 7, independent power supply control for multiple circuits can be achieved, meeting the differentiated power needs of different loads. When a fault occurs in a certain load, the corresponding circuit breaker can quickly disconnect, avoiding impact on other circuits and significantly improving the reliability and fault tolerance of the power supply system. The circuit breaker input is connected to the disconnecting switch via the distribution busbar, and the output is connected to branch outgoing unit 3 and street light unit 4 respectively. This structure combining centralized power distribution and distributed output ensures efficient power distribution while simplifying the internal wiring layout and facilitating later maintenance and repair.

[0043] The intelligent gateway 6, electrically connected to key units such as incoming lines, metering, and feeders, establishes a comprehensive monitoring and control network. It can capture the operating parameters of each unit in real time, and through intelligent analysis, provide early warnings of abnormal states, proactively avoiding potential faults. This significantly improves system safety and maintainability, and reduces manual inspection costs. The intelligent gateway 6 can also track the status of the emergency power interface 8, reporting access status, switching records, and load data in real time. This allows the remote monitoring center to accurately grasp the dynamics of emergency power supply, providing data support for emergency command and shortening response decision-making time.

[0044] In some embodiments, a switching control unit is also included, which is connected to the emergency power interface 8 and the power distribution busbar respectively. The emergency power interface 8 is electrically connected to the power distribution busbar through the switching control unit.

[0045] Emergency power interface 8 is electrically connected to the emergency power supply.

The metering unit 5 is located in the front middle of the enclosure 1, allowing staff to easily view power data and operate related equipment without needing to enter the enclosure, improving work efficiency and reducing operational risks. The feeder unit 7 is located in the rear middle, shortening the connection path to the incoming line unit 2 and branch outgoing line unit 3, reducing power transmission loss, and avoiding excessive intersections with other unit lines, reducing signal interference and ensuring power supply stability. The street light unit 4 is independently located on the left, forming a dedicated power supply area, making its line management and maintenance more convenient and less susceptible to impacts from other unit failures.

[0051] In some embodiments, the smart gateway 6 is located at the front of the middle of the housing 1.

[0052] In some embodiments, the front of the box 1 is provided with three doors, corresponding to the street light unit 4, the metering unit 5 and the incoming line unit 2 respectively. The back of the box 1 is provided with three doors, corresponding to the incoming line unit 2, the feeder unit 7 and the street light unit 4 respectively. The metering unit 5 is separated from the street light unit 4, the feeder unit 7 and the incoming line unit 2 by a partition. The upper part of the door corresponding to the metering unit 5 is provided with an observation window.

[0053] The front three doors of enclosure 1 correspond to the streetlights, metering, and incoming line unit 2, while the rear three doors correspond to the incoming line, feeder line, and streetlight unit 4, forming a two-way operating channel. Workers can choose to operate from the front or back according to their needs, improving maintenance convenience and reducing operation time. Metering unit 5 is independently separated by a partition, preventing interference from other units' wiring and ensuring accurate metering data. The door corresponding to metering unit 5 is equipped with an observation window, allowing direct viewing of energy data without opening the door, reducing dust intrusion and the risk of electric shock, and facilitating daily inspections. The independent doors and partitions for each unit enable more precise fault diagnosis. In case of a single unit failure, only the corresponding door needs to be opened for inspection, avoiding complete exposure of internal wiring, reducing the risk of accidental electric shock, and minimizing the impact on the normal operation of other units.

[0054] In some embodiments, the housing 1 is made of stainless steel with an IP44 protection rating. Louvered ventilation holes 9 are provided on both sides of the housing 1. The louvered ventilation holes 9 are located at the lower edge of the top cover of the housing 1. The louvered ventilation holes 9 are welded with 20-mesh steel mesh. A cooling fan is provided at the top inside the housing 1.

[0055] The enclosure 1 is made of stainless steel, possessing excellent corrosion and oxidation resistance, enabling it to adapt to complex environments such as humidity and dust, thus extending its service life. Its IP44 protection rating effectively prevents dust intrusion and water splashes, providing reliable protection for internal electrical components and ensuring stable system operation in outdoor settings. The louvered ventilation holes 9 along the lower edge of the top cover on both sides of enclosure 1 utilize the principle of rising hot air to promote natural convection cooling, while their concealed location reduces the risk of rainwater directly entering. 20-mesh steel mesh is welded to the louvered ventilation holes 9, ensuring adequate ventilation while preventing insects and debris from entering enclosure 1, thus avoiding the risk of short circuits. The cooling fan at the top of enclosure 1 works in conjunction with natural ventilation to quickly dissipate accumulated heat, preventing component aging or performance degradation under high-temperature environments and ensuring efficient and stable equipment operation.

[0056] In some embodiments, the box body 1 is powder-coated sea gray B05, and the door of the box body 1 is silkscreened with a red "Danger: Electricity - Do Not Climb" sign.

[0057] The enclosure 1 is powder-coated in sea gray B05 color. The powder coating process enhances the surface's wear resistance and corrosion resistance. The red "Danger: Electricity - Do Not Climb" sign silkscreened on the enclosure door is bright and eye-catching, quickly attracting the attention of personnel, strengthening the safety warning effect, effectively preventing the risk of electric shock caused by non-professionals' misoperation or approach, and improving the level of on-site safety management.

[0058] In some embodiments, the cabinet door is equipped with a transformer pull rod lock and a stainless steel triple hinge.

[0059] The transformer box door is equipped with a pull rod lock, which ensures that the door closes tightly and securely, protecting the internal equipment from human damage or accidental contact.

[0063] The inlet port 10 is equipped with a 150mm diameter elbow, and the outlet port 11 is equipped with a 120mm diameter elbow. This can reduce stress damage when the cable is bent, avoid insulation layer cracking or conductor breakage caused by excessive bending, and extend the service life of the cable. The elbow design can also guide the cable route, making the internal wiring more organized and facilitating later maintenance.

[0064] In some embodiments, the opening of the bend is provided with a special plastic plug.

[0065] The bend in the pipe is equipped with a special plastic plug that can tightly fill the gaps, effectively preventing dust, moisture and small insects from entering, protecting the electrical connections at the interface from corrosion, and avoiding wear caused by cable shaking and friction, further enhancing the integrity of the enclosure's protection.
