[0035] See Figure 1 , Figure 1 A schematic cross-sectional view of a power distribution box according to an embodiment of the present application is shown. The power distribution box provided in one embodiment of the present application includes a housing 100, a connecting mechanism 200, a socket mechanism 300, and an acquisition mechanism 400. The housing 100 is provided with a housing 100A and an opening, the opening communicating with the housing 100A. The housing 100 includes an outer door 120 and an inner door 110. The outer door 120 is movably connected to the housing 100 and can open or close the opening. The inner door 110 is movably disposed within the housing 100A. The housing 100A is divided into a first cavity 100B and a second cavity 100C by the inner door 110. The connecting mechanism 200 is mounted within the first cavity 100B and is configured to electrically connect to an external power source. The connecting mechanism 200 is configured to distribute electrical energy and detect current, voltage, and power data before and after distribution. The socket mechanism 300 is installed on the inner door 110 and is electrically connected to the connection mechanism 200 via a secondary line. The acquisition mechanism 400 is connected to the connection mechanism 200 and is used to acquire current, voltage and power data and transmit them to the host computer.
[0036] The power distribution box described in the embodiment of the present application is divided into a first chamber 100B and a second chamber 100C by an inner door 110 within the housing 100. A connecting mechanism 200 is installed in the first chamber 100B, connecting an external power source to the first chamber 100B and connecting to the connecting mechanism 200. The connecting mechanism 200 is electrically connected to the socket mechanism 300 via a secondary line. The socket mechanism 300 is installed on the inner door 110. Therefore, the inner door 110 seals the first chamber 100B, preventing internal wiring from being exposed and reducing electrical risks. Electrical equipment can obtain power through the socket mechanism 300 in the second chamber 100C. The connecting mechanism 200 can reasonably distribute the electrical energy and detect the parameters of the circuit power before and after distribution.
[0037] The power distribution box described in the embodiment of the present application, by setting a connecting mechanism 200 to connect the socket mechanism 300, thereby reasonably distributing and opening or closing the power supply, and monitoring the input and output power supply, can avoid the output of non-standard power supply causing damage to electrical equipment, ensure standardized electricity use, and protect electricity safety. It has the advantages of good standardization and high safety performance.
[0038] Combine Figure 2 As shown, Figure 2 A schematic diagram of the structure of the first chamber 100B of a power distribution box in one embodiment of the present application is shown. In some embodiments, the connection mechanism 200 includes a first intelligent circuit breaker 210 and a second intelligent circuit breaker 220. The first intelligent circuit breaker 210 and the second intelligent circuit breaker 220 are installed in the first chamber 100B. The first intelligent circuit breaker 210 is electrically connected to an external three-phase power supply, and the second intelligent circuit breaker 220 is electrically connected to an external single-phase power supply. Because electrical equipment has different power specifications, by providing the first intelligent circuit breaker 210 and the second intelligent circuit breaker 220, the first intelligent circuit breaker 210 can control the output of a three-phase high current, while the second intelligent circuit breaker 220 can control the output of a single-phase low current. Electrical equipment can choose to connect to the first intelligent circuit breaker 210 or the second intelligent circuit breaker 220 according to its power demand, thereby providing standardized power supply to the electrical equipment, avoiding equipment shutdown or damage, and improving power safety. In an illustrative example, the first intelligent circuit breaker 210 is a three-phase 250A intelligent circuit breaker, and the second intelligent circuit breaker 220 is a single-phase 30mA intelligent circuit breaker. The first intelligent circuit breaker 210 and the second intelligent circuit breaker 220 can manage the three-phase imbalance in the substation, specifically including a phase-changing controller and a phase-changing switch. The phase-changing controller can automatically balance the load of the distribution network without power outages. The intelligent phase-changing switch has the function of receiving control strategies from the upper computer and can correctly execute the phase-changing tasks according to the strategies.
[0039] like Figure 3 As shown, Figure 3A schematic diagram of the structure within the second cavity 100C of a power distribution box in one embodiment of the present application is shown. In an optional embodiment, the socket mechanism 300 includes a first socket 310, a second socket 320, a plug, and an extension cable. The first socket 310 and the second socket 320 are both mounted on the inner door 110. The first socket 310 is electrically connected to the first intelligent circuit breaker 210 via a secondary line, and the second socket 320 is electrically connected to the second intelligent circuit breaker 220 via a secondary line. The plug is connected to the extension cable and is detachably inserted into the second socket 320. Specifically, the first socket 310 is a three-phase, five-hole, 63A industrial socket, and the second socket 320 is a single-phase, five-hole, 16A industrial socket. By setting the first socket 310 to be connected to the first intelligent circuit breaker 210, the first socket 310 matches the output power of the first intelligent circuit breaker 210, and the second socket 320 to be connected to the second intelligent circuit breaker 220, the second socket 320 matches the output power of the second intelligent circuit breaker 220, so that electrical equipment can choose to be connected to the first socket 310 or the second socket 320 according to different needs, thereby achieving the purpose of standardized electricity use and ensuring electricity safety.
[0040] Furthermore, if the electrical equipment is far away from the power distribution box, the plug connected to the extension cable can be inserted into the first socket 310 or the second socket 320. The extension cable can expand the power supply range and provide power to electrical equipment in more distant places, making it easier for staff to operate. It has the advantages of multiple application scenarios and easy use.
[0041] In one exemplary embodiment, both first and second sockets 310 and 320 are variable rear sockets. These variable rear sockets can quickly, safely, and efficiently connect to various low-voltage devices by changing the rear connection method. The plugs are round, self-locking plugs. These round, self-locking plugs, combined with the variable rear sockets, allow for safe and reliable docking, ensuring electrical safety. Furthermore, an extension cable can be mounted on a removable pulley reel, which conveniently stores the extension cable, extending its reach and adapting to various emergency scenarios.
[0042] In an optional embodiment, the connection mechanism 200 further includes an insulating wire harness slot, which is mounted in the first cavity 100B and into which the secondary wires are mounted. The provision of the insulating wire harness slot allows the secondary wires used for wiring within the first cavity 100B to be routed through the insulating wire harness slot, facilitating wire organization within the power distribution box, standardizing secondary wire routing, and reducing dangerous situations such as short circuits between wires, thereby improving the safety of the power distribution box.
[0043] In an optional embodiment, if Figure 1 and Figure 2As shown, the acquisition mechanism 400 includes an intelligent gateway 410 and a switch. The intelligent gateway 410 is provided with an input communication interface and an output communication interface. The input communication interface is electrically connected to the first intelligent circuit breaker 210 and the second intelligent circuit breaker 220, and the output communication interface is electrically connected to the switch. The switch is used to connect to a host computer. By setting up the intelligent gateway 410, various data of the first intelligent circuit breaker 210 and the second intelligent circuit breaker 220 can be obtained and transmitted to the host computer through the switch. The host computer can analyze and monitor various data of the power distribution box and issue control instructions to control the first intelligent circuit breaker 210 and the second intelligent circuit breaker 220 to reasonably distribute electrical energy, thereby achieving the purpose of regulating electricity use and avoiding safety accidents.
[0044] In an optional embodiment, if Figure 2 As shown, the power distribution box also includes a dehumidification mechanism 500, which is installed in the first cavity 100B and is used to dehumidify the accommodating chamber 100A. By installing the dehumidification mechanism 500 in the first cavity 100B, the humidity in the first cavity 100B is controlled to be low, thereby protecting the insulation performance of the electrical equipment, reducing the occurrence of electrical faults, and reducing the risk of short circuits and leakage, thereby helping to improve the stability and reliability of the power distribution box.
[0045] In an optional embodiment, if Figure 4 As shown, the connection mechanism 200 also includes a wire adapter, which electrically connects the connection mechanism 200 to external power sources of different wire diameters. The top of the housing 100 is provided with a wire inlet and outlet hole 100D, through which the connection mechanism 200 connects to the external power source. By providing the wire adapter, the external power source is introduced into the first cavity 100B through the wire inlet and outlet hole 100D and connected to the wire adapter, allowing cables of different specifications to be easily connected to the connection mechanism 200, providing the advantage of ease of use.
[0046] In an optional embodiment, if Figure 1 As shown, the housing 100 further includes a mounting plate 130, which is mounted on the inner wall of the first cavity 100B. The first intelligent circuit breaker 210, the second intelligent circuit breaker 220, and the intelligent gateway 410 are all mounted on the mounting plate 130. By providing the mounting plate 130, the first intelligent circuit breaker 210, the second intelligent circuit breaker 220, and the intelligent gateway 410 are all mounted on the mounting plate 130. The mounting plate 130 is made of insulating material, which can reduce the risk of electrical leakage in electrical equipment and improve safety.
[0047] In an optional embodiment, if Figure 3As shown, the mounting plate 130 is further provided with an indicator light 230, which includes three indicator lights 230, each of which is electrically connected to a single-phase circuit. By providing the indicator lights 230, the status of each phase connected to the external power supply can be easily understood, making it convenient for staff to check the situation.
[0048] In an optional embodiment, the housing 100 is made of 304 non-magnetic stainless steel, which can improve the load-bearing capacity and corrosion resistance of the housing 100. In addition to the first cavity 100B and the second cavity 100C, the housing 100 can also be equipped with a feeder chamber, a metering chamber, an incoming line chamber, etc. as needed, thereby achieving a modular internal structure, a compact structure, and rapid installation.
[0049] In an optional embodiment, the box body 100 is further provided with a seal, which is disposed between the outer door 120 and the box body 100. Specifically, the seal is a high-mechanical-strength sealing rubber waterproof groove with multiple layers of interlocking folded edges, which can ensure ventilation and heat dissipation while having strong waterproof, dustproof, and sandproof capabilities, and has the advantage of good protective performance.
[0050] Furthermore, the housing 100 includes a roof, which is located on top of the housing 100. The roof protects the housing 100 from rain damage. Specifically, the roof is made of a non-metallic SMC insulating composite material based on a carbon-silicon combination, which effectively resists damage from water, gasoline, electric shock salts, acetic acid, and sodium-potassium compounds. It maintains excellent physical and mechanical properties over a long period of time after being corroded by various acidic and alkaline soils and acid rain, and can be used in highly polluted outdoor locations, demonstrating its excellent stability.
[0051] Furthermore, the outer door 120 and the inner door 110 are connected to the box body 100 via concealed hinges, and the outer door 120 is equipped with a passive electronic lock. The concealed hinges make the connection between the outer door 120 and the inner door 110 more secure, and the passive electronic lock on the outer door 120 improves the safety performance of the power distribution box.
[0052] The power distribution box described in the embodiment of the present application has the following beneficial effects:

By setting the connection mechanism 200 to connect the socket mechanism 300, the power supply can be reasonably distributed and opened or closed, and the output power can be monitored, so as to avoid the output of non-standard power supply causing damage to electrical equipment, ensure standardized electricity use, and protect electricity safety. It has the advantages of good standardization and high safety performance.

By setting up the intelligent gateway 410, various data of the first intelligent circuit breaker 210 and the second intelligent circuit breaker 220 can be obtained and transmitted to the host computer through the switch. The host computer can analyze and monitor the various data of the power distribution box and issue control instructions to control the first intelligent circuit breaker 210 and the second intelligent circuit breaker 220 to reasonably distribute electric energy, thereby achieving the purpose of regulating electricity use and avoiding safety accidents.
