Description

Technical Field

[0001] This utility model relates to the field of intelligent distribution boxes, and more specifically, to an intelligent distribution box and a power distribution system. Background Technology

[0002] The biggest difference between smart distribution boxes and traditional distribution boxes lies in their automation and intelligent monitoring capabilities. Traditional distribution boxes can only perform basic switching control functions and cannot monitor or remotely control the operating status of electrical equipment in real time. When data such as current and voltage exceed limits, they cannot issue timely warnings and take appropriate measures, leading to damage to electrical equipment and instability in the power system. Furthermore, ordinary distribution boxes lack real-time data collection and analysis of the power system, hindering effective energy conservation and optimization management. In contrast, smart distribution boxes possess powerful intelligent control functions in areas such as automated control, real-time power monitoring, remote control, and energy-saving optimization. Smart distribution boxes play a crucial role in home energy storage products, providing safe, intelligent, and efficient power supply for households and serving as key equipment for the stable operation and optimized management of home energy storage systems.

[0003] Currently, smart distribution boxes are divided into two types. One type does not have a fuel-electric input module. This type of smart distribution box can monitor and manage the power from the mains and the home energy storage system battery. However, if there is a grid interruption and the battery in the home energy storage system is low on power, household appliances will lose power. The other type has a fuel-electric input module, which is deeply integrated with the distribution box. This type of smart distribution box can monitor and manage the power from the mains, the home energy storage system battery, and the power generated by the generator. Since the generator generates electricity from fuel, it can cope with various sudden power outages. However, this type of smart distribution box is more expensive. The fuel-electric input module in this type of smart distribution box is redundant for users whose homes do not have a fuel engine. Users need to pay an extra fee for it. Therefore, this type of smart distribution box cannot well meet the different needs of users who need a fuel-electric input module and those who do not. Utility Model Content

[0004] In order to solve or improve the above-mentioned technical problem of poor expandability of the input module of the distribution box, one objective of this utility model is to provide an intelligent distribution box.

[0005] Another objective of this invention is to provide a power distribution system.

[0006] To achieve the above objectives, the first aspect of this utility model provides an intelligent power distribution box, comprising: a box body; a generator housing cavity disposed within the box body, the generator housing cavity being used to accommodate a generator-electric input module when the intelligent power distribution box expands its generator power generation function; a control board disposed within the box body, the control board having a first signal terminal, the first signal terminal being used to adapt to a second signal terminal of the generator-electric input module; and a main circuit disposed within the box body, the main circuit having a first conductive element, the first conductive element being used to adapt to a second conductive element of the generator-electric input module; wherein, the control board is used to monitor or control the generator-electric input module after the first conductive element and the second conductive element are connected and the first signal terminal is connected to the second signal terminal.

[0007] The intelligent power distribution box provided by this utility model has a pre-reserved expansion interface for generator input and a pre-reserved generator housing cavity before leaving the factory. If the user needs to increase generator input during the use of the intelligent power distribution box, the user can purchase a generator input module compatible with the intelligent power distribution box separately. By placing the generator input module into the pre-reserved generator housing cavity and connecting the relevant interfaces of the generator input module to the pre-reserved generator input expansion interface, the function of expanding the generator input of the intelligent power distribution box can be quickly completed. The intelligent power distribution box provided by this utility model utilizes the modular design of the generator input module, which allows for quick and convenient retrofitting of the generator input module, while also meeting the needs of different users for generator power generation.

[0008] Through modular design, it can flexibly meet the input requirements of both mains power and generator power. Specifically, the intelligent power distribution box includes a cabinet, a control board, a main circuit, and a generator power input module. The cabinet serves as the external structure of the intelligent power distribution box. By setting up a generator housing cavity inside the cabinet, it can accommodate the generator power input module when the power generation function of the intelligent power distribution box is expanded, i.e., when the generator power generation function is expanded. At the same time, the cabinet also provides a certain degree of protection for the internal structure. Especially when the intelligent power distribution box is placed outdoors, the cabinet can effectively prevent the external environment from affecting the internal electrical components, ensuring that the equipment can work normally under various conditions.

[0009] Furthermore, by installing the control board inside the enclosure, it is easy to connect and wire with other components, while also being protected by the enclosure. Since the control board is equipped with a first signal terminal, it is connected to the second signal terminal of the oil-electric input module through the first signal terminal, realizing signal transmission between the control board and the oil-electric input module. This enables the control board to control the oil-electric input module, ensuring that the control board can accurately obtain the status information of the oil-electric input module and issue control commands as needed to realize the functions of starting, stopping, and speed regulation of the generator.

[0010] The main circuit is installed inside the box. A first conductive component is installed on the main circuit to adapt to the second conductive component of the oil-electric input module. When the first and second conductive components are connected, the oil-electric input module is electrically connected to the main circuit, so that the electrical energy generated by the generator can be input into the distribution box.

[0011] The control board is used to control the oil-electric input module after the first conductive component and the second conductive component are connected and the first signal terminal is connected to the second signal terminal, and after the oil-electric input module is connected to the distribution box, the control board detects the connection status and confirms that the connection is normal, so that it can start, run and stop as needed.

[0012] In addition, the above-mentioned technical solution provided by this utility model may also have the following additional technical features:

[0013] In the above technical solution, the oil-electric input module is an optional accessory.

[0014] The hybrid power input module is an optional accessory, allowing users to choose whether to equip it according to their actual needs. This enables the distribution box to better meet the diverse needs of different users. In special scenarios, such as temporary power outages due to weather, or when the mains power supply was previously used and there is a need for generator power generation, the hybrid power input module can be installed in the distribution box to meet the corresponding requirements.

[0015] The above technical solution also includes: a generator cover plate, which is located inside the housing. The generator cover plate is detachably connected to the housing and is used to cover the generator housing cavity.

[0016] By incorporating a generator cover that can be detachably connected to the housing, the generator input module can be quickly installed or removed when needed, improving the system's flexibility and ease of maintenance.

[0017] When the oil-electric input module is not in use, the generator cover can effectively prevent dust, moisture and other external impurities from entering the generator housing cavity, protecting the internal components.

[0018] In the above technical solution, the oil-electric input module includes: an oil-electric base plate; a relay mounted on the oil-electric base plate; and a circuit breaker electrically connected to the relay, which is used to connect the oil-electric input cable.

[0019] In this technical solution, the hydraulic-electric input module includes a hydraulic base plate, relays, and circuit breakers. The hydraulic base plate, serving as the foundation plate, is connected to the enclosure and is located at the bottom of the module, providing support for other components. Furthermore, relays and circuit breakers are essential structures for the hydraulic-electric input module. Relays control the on / off state of the circuit, automatically switching it via control signals to ensure rapid response when needed, providing flexibility and safety for power input. Circuit breakers protect the circuit from overload or short circuits, automatically disconnecting the circuit when the current exceeds safe limits to prevent equipment damage and fires, ensuring the safety of the system and the user.

[0020] The oil-electric input cable can connect an external oil power source to the module, ensuring that power can be smoothly input into the module and realizing the effective use of the generator's power generation function.

[0021] The above technical solution also includes: a signal board, which is spaced apart from the base plate of the electric power plant, and a second signal terminal including the signal interface of the signal board.

[0022] In this technical solution, the oil-electric input module also includes a signal board, which is spaced apart from the oil-electric base plate to avoid mutual interference. The signal board measures current and energy for protection and control of the power system, and can also be used for fault diagnosis and fault recording. The signal interface is a connection port on the signal board used to connect to external devices or lines. The second signal terminal includes a signal interface, through which the oil-electric input module can communicate and transmit data with other devices, enabling monitoring, control, and management of the generator's operating status.

[0023] The above technical solution also includes: a current transformer, located at the connection between the relay and the circuit breaker, the current transformer being used to collect electrical parameters at the connection.

[0024] By setting up a current transformer, electrical parameters at the connection point between the relay and the circuit breaker can be effectively collected. Specifically, the electrical parameters include power, current, voltage, etc. The signal board can transmit the electrical parameters collected by the current transformer to the control board through signals, thereby realizing the monitoring of the electrical parameters and then realizing control based on the above parameters.

[0025] For example, by detecting abnormal currents (such as overload or short circuit) through current transformers, relays and circuit breakers can be triggered in a timely manner to ensure circuit safety.

[0026] In the above technical solution, the connection part includes: an input copper busbar, one end of which is electrically connected to the circuit breaker, and the other end of which is electrically connected to the input terminal of the relay. The input copper busbar passes through the current transformer.

[0027] A copper busbar is used to connect the circuit breaker and the relay. Specifically, the input copper busbar serves as the conductor for power transmission. The two ends of the input copper busbar are connected to the input terminals of the circuit breaker and the relay, respectively. By utilizing the conductivity of the copper busbar's own structure, energy loss during power transmission can be reduced, and a stable electrical connection can be provided, thereby enhancing the overall reliability of the system.

[0028] In addition, the input copper busbar passes through the current transformer, which can detect relevant electrical parameters based on the transformer principle, mainly detecting the magnitude of the current flowing between the circuit breaker and the relay.

[0029] In the above technical solution, the base plate of the oil-electric system is a metal part, and the input copper busbar, relay and current transformer are assembled into the first module. The oil-electric input module also includes an insulating column, which is set on the base plate of the oil-electric system, and one end of the insulating column is connected to the first module.

[0030] In this technical solution, the base plate is made of metal. The strength of metal can ensure the stability and durability of the entire module. The input copper busbar, relay and current transformer are pre-assembled to form a modular first module, which facilitates the subsequent assembly with other parts. In particular, the first module is suspended on the base plate by insulating pillars. The insulating pillars can isolate the first module from the base plate, thereby preventing short circuits or leakage caused by current passing through the metal base plate and improving the safety of the system.

[0031] In the above technical solution, the first conductive component includes a sub-copper busbar, which is disposed in the main circuit; the second conductive component includes an output copper busbar, one end of which is electrically connected to the output terminal of the relay, and the other end of which is electrically connected to the sub-copper busbar.

[0032] The first and second conductive components, which establish the electrical connection between the hybrid input module and the main circuit, are both copper busbars. These busbars have low resistance, enabling efficient current transmission and reducing energy loss. Furthermore, they provide a reliable connection for power transmission, ensuring the normal operation of the main circuit. The first conductive component is a sub-busbar, and the second conductive component is an output busbar. The sub-busbar, as part of the main circuit, transmits power, while the output busbar connects the relay output terminal to the sub-busbar of the main circuit, thus achieving the electrical connection between the hybrid input module and the main circuit, and smoothly transmitting the power generated by the hybrid input module to the main circuit.

[0033] Of course, since one end of the output copper busbar is electrically connected to the output terminal of the relay and the other end is electrically connected to the sub-copper busbar, this design allows the oil-electric input module to be easily connected and disconnected from the main circuit, improving the system's flexibility and maintainability.

[0034] When the sub-copper busbar of the first conductive element and the output copper busbar of the second conductive element are connected, the power generated by the oil-electric input module can be smoothly transmitted to the main circuit, providing power support for the intelligent distribution box and ensuring its normal operation.

[0035] In the above technical solution, the circuit breaker is located on the side of the first module away from the base plate of the oil and electricity system, and the output end of the circuit breaker is located close to the output copper busbar. The oil and electricity input module also includes a connecting copper busbar, which is located between the circuit breaker and the first module. One end of the connecting copper busbar is connected to the output end of the circuit breaker, and the other end of the connecting copper busbar is connected to the input copper busbar.

[0036] In this design, the circuit breaker is positioned on the side of the first module furthest from the base plate, with its output terminal close to the output copper busbar. This reduces the power transmission path and improves transmission efficiency. Furthermore, a connecting copper busbar connects the circuit breaker's output terminal to the input copper busbar. Specifically, one end of the connecting copper busbar is connected to the circuit breaker's output terminal, and the other end is connected to the input copper busbar.

[0037] For the first module, the output terminal of the circuit breaker and the input copper busbar are located at opposite ends. By setting up connecting copper busbars, the two are connected together, ensuring power transmission and making the power transmission path of the entire oil-electric input module more direct and efficient, thus improving the system's power transmission efficiency and reliability. At the same time, the modular design also simplifies the system's installation and maintenance process.

[0038] The above technical solution also includes: an input port, located on the periphery of the enclosure, through which part of the oil and electricity input cable passes and connects to the input terminal of the circuit breaker.

[0039] By setting inlet ports on the perimeter walls of the enclosure, a channel is provided for the oil and electricity input cables to enter the enclosure, reducing the impact of the external environment on the cables.

[0040] It is understandable that some of the oil and electricity input cables pass through the input port and are directly connected to the input terminal of the circuit breaker, which simplifies the connection process and improves the convenience of installation and maintenance.

[0041] The above technical solution also includes: a first connecting hole, provided on the base plate of the electric hydraulic system; and a second connecting hole, provided on the housing; wherein the connection between the base plate of the electric hydraulic system and the housing is realized through the first connecting hole and the second connecting hole.

[0042] In this technical solution, a first connecting hole and a second connecting hole are respectively provided on the base plate and the housing. The size and shape of the first connecting hole are designed according to the connection requirements and the specifications of the fasteners. The second connecting hole is provided on the housing and matches the shape and size of the first connecting hole to ensure that the fasteners can pass through smoothly and achieve connection.

[0043] The above technical solution includes: an AC power input module, which is connected to the main circuit and connected to an AC power input cable.

[0044] By installing the AC power input module inside the enclosure, which is connected to the main circuit, the AC power input is transmitted to the main circuit and then distributed to the load. Simultaneously, it is connected to the AC power input cable to enable AC power access. It can be understood that in this solution, the AC power input module inside the intelligent distribution box is a standard option for the entire intelligent distribution box, and a hybrid power input module can be optionally added.

[0045] Furthermore, the mains power input module is connected to the control board via signal, and the control board is used to monitor or control the mains power input module.

[0046] The control board can monitor and control the mains input module, such as monitoring parameters like voltage, current, and frequency of the mains power, and controlling the switching status of the mains input module. It can perform corresponding operations based on the mains power conditions. For example, when the mains power is normal, it controls the mains input module to conduct and supply power to the load; when the mains power is abnormal, it cuts off the mains input in time to avoid damage to the load.

[0047] The control panel enables automatic switching and control between mains power and generator power supply modes, improving the reliability and flexibility of power supply. In the event of a mains power failure, the generator can be quickly started to ensure continuous power supply to the load; after the mains power is restored, it can automatically switch back to mains power supply, achieving intelligent power management.

[0048] The second aspect of this utility model provides a power distribution system, including: any of the above-mentioned intelligent distribution boxes; a mains power input cable connected to the mains power input module of the intelligent distribution box; and a hydraulic power input cable connected to the hydraulic power input module of the intelligent distribution box.

[0049] According to the technical solution of the power distribution system of this utility model, the power distribution system includes an intelligent distribution box, a mains power input cable, and a fuel-powered input cable. The intelligent distribution box receives mains power and fuel-powered power input and distributes the power to various load devices. The mains power input cable is connected to the mains power input module of the intelligent distribution box, introducing mains power into the power distribution system to provide regular power supply to the load devices. The fuel-powered input cable is connected to the fuel-powered input module of the intelligent distribution box, and in the event of a mains power failure or the need for emergency power supply, it inputs the power generated by the generator into the power distribution system as a backup power source.

[0061] To better understand the above-mentioned objectives, features, and advantages of the embodiments of this utility model, the embodiments of this utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0062] Many specific details are set forth in the following description in order to provide a full understanding of this application. However, embodiments of the present invention may also be implemented in other ways different from those described herein. Therefore, the scope of protection of this application is not limited to the specific embodiments disclosed below.

[0063] One existing type of smart distribution box does not include a fuel-electric input module. This type of smart distribution box can monitor and manage the power from the mains and the home energy storage system's battery. However, if there is a grid interruption and the battery in the home energy storage system is low on power, household appliances will lose power. Another existing type includes a fuel-electric input module, which is deeply integrated with the distribution box. This type of smart distribution box can monitor and manage the power from the mains, the home energy storage system's battery, and the power generated by the generator. Since the generator generates electricity from fuel, it can cope with various sudden power outages. However, this type of smart distribution box is more expensive. The fuel-electric input module in this type of smart distribution box is redundant for users whose homes do not have a fuel-electric engine, requiring them to pay an additional fee. Therefore, this type of smart distribution box cannot well meet the different needs of users who require and do not require a fuel-electric input module.

[0064] The following reference Figures 1 to 7 This invention describes an intelligent distribution box and power distribution system provided according to some embodiments of the present invention.

[0065] In view of this, such as Figure 1 , Figure 2 and Figure 3 As shown, this utility model proposes a new intelligent power distribution box 100, including: a box body 101; a generator housing cavity 1012, disposed within the box body 101, the generator housing cavity 1012 is used to accommodate the generator input module 106 when the intelligent power distribution box 100 expands the generator power generation function; a control board 102, disposed within the box body 101, the control board 102 is provided with a first signal terminal, the first signal terminal is used to adapt to the second signal terminal 1104 of the generator input module 106; a main circuit 104, disposed within the box body 101, the main circuit 104 is provided with a first conductive element, the first conductive element is used to adapt to the second conductive element of the generator input module 106; wherein, the control board 102 is used to monitor or control the generator input module 106 after the first conductive element and the second conductive element are connected and the first signal terminal is connected to the second signal terminal 1104.

[0066] The intelligent power distribution box 100 provided by this utility model has a reserved expansion interface for generator input and a reserved generator housing cavity 1012 before leaving the factory. If the user needs to increase the input of generator power generation during the use of the intelligent power distribution box 100, the user can purchase a generator input module compatible with the intelligent power distribution box 100 separately. By placing the generator input module into the reserved generator housing cavity 1012 and connecting the relevant interface of the generator input module to the reserved generator input expansion interface, the function of expanding the generator input of the intelligent power distribution box 100 can be quickly completed. The intelligent power distribution box 100 provided by this utility model utilizes the modular design of the generator input module, which allows for quick and convenient retrofitting of the generator input module, while meeting the needs of different users for generator power generation.

[0067] Through modular design, it can flexibly meet the input requirements of mains power and generator. Specifically, the intelligent power distribution box 100 includes a box body 101, a control board 102, a main circuit 104, and a generator input module 106. The box body 101 serves as the external structure of the intelligent power distribution box 100. By setting a generator housing cavity 1012 inside the box body 101, the generator input module 106 can be accommodated when the power generation function of the intelligent power distribution box 100 is expanded, that is, when the generator power generation function is expanded. At the same time, the box body 101 also plays a certain role in protecting the internal structure. Especially when the intelligent power distribution box 100 is placed in an outdoor setting, the box body 101 can effectively prevent the influence of the external environment on the internal electrical components, ensuring that the equipment works normally under various conditions.

[0068] Furthermore, by installing the control board 102 inside the housing 101, it is easy to connect and wire with other components, while also being protected by the housing 101. Since the control board 102 is provided with a first signal terminal, it is connected to the second signal terminal 1104 of the oil-electric input module 106 through the first signal terminal, realizing signal transmission between the control board 102 and the oil-electric input module 106. This enables the control board 102 to control the oil-electric input module 106, ensuring that the control board 102 can accurately obtain the status information of the oil-electric input module 106 and issue control commands as needed to realize the functions of starting, stopping, and speed regulation of the generator.

[0069] A main circuit 104 is installed inside the housing 101. A first conductive element is installed on the main circuit 104 to adapt to the second conductive element of the oil-electric input module 106. When the first conductive element and the second conductive element are connected, the oil-electric input module 106 is electrically connected to the main circuit 104, so that the electrical energy generated by the generator can be input into the distribution box.

[0070] The control board 102 is used to control the oil-electric input module 106 after the first conductive element 1122 and the second conductive element 1124 are connected and the first signal terminal 1102 is connected to the second signal terminal 1104. After the oil-electric input module 106 is connected to the distribution box, the control board 102 detects the connection status and confirms that the connection is normal, so that it can start, run and stop as needed.

[0071] The system also includes a generator cover 108 that is detachably connected to the housing 101, which facilitates the quick installation or removal of the oil and electricity input module 106 when needed, thereby improving the system's flexibility and ease of maintenance.

[0072] When the oil-electric input module is not in use, the oil generator cover can effectively prevent dust, moisture and other external impurities from entering the oil generator housing 1012, protecting the internal components.

[0073] In one embodiment, the oil-electric input module 106 is an optional accessory, allowing users to choose whether to equip it according to their actual needs. This enables the distribution box to better meet the diverse needs of different users. In special scenarios, such as temporary power outages due to weather, or when the mains power supply was previously used and there is a need for generator power generation, the oil-electric input module 106 can be installed in the distribution box to meet the corresponding needs.

[0074] In a specific embodiment, Figure 7 As shown, the hydraulic power input module 106 includes a hydraulic power base plate 1062, a relay 1064, and a circuit breaker 1066. The hydraulic power base plate 1062 serves as a base plate, connected to the housing 101. Located at the bottom of the hydraulic power input module 106, the base plate 1062 provides support for other components of the module. Furthermore, the relay 1064 and circuit breaker 1066 are both essential structures of the hydraulic power input module 106. The relay 1064 controls the on / off state of the circuit, automatically switching the circuit via control signals to ensure rapid response when needed, providing flexibility and safety for power input. The circuit breaker 1066 protects the circuit from overload or short circuit. When the current exceeds safe limits, it automatically disconnects the circuit to prevent equipment damage and accidents such as fires, ensuring the safety of the system and the user.

[0075] The oil-electric input cable 204 can connect an external oil power source to the module, ensuring that power can be smoothly input into the module and realizing the effective use of the generator's power generation function.

[0076] In one embodiment, alternatively, such as Figure 7As shown, the oil-electric input module 106 also includes a signal board 1068, which is spaced apart from the oil-electric base plate 1062 to avoid mutual interference. The signal board 1068 is used to measure current and energy, for the protection and control of the power system, and can also be used for fault diagnosis and fault recording. The signal interface 1069 is a connection port on the signal board 1068 for connecting external devices or lines. The second signal terminal includes the signal interface 1069. Through the signal interface 1069, the oil-electric input module 106 can communicate and transmit data with other devices, enabling the monitoring, control, and management of the generator's operating status.

[0077] In one embodiment, optionally, a current transformer 1067 is provided, which can effectively collect electrical parameters at the connection between the relay and the circuit breaker. Specifically, the electrical parameters include power, current, voltage, etc. The signal board 1068 can transmit the electrical parameters collected by the current transformer 1067 to the control board 102 through a signal, thereby realizing the monitoring of the electrical parameters and then realizing control based on the above parameters.

[0078] For example, by detecting abnormal current (such as overload or short circuit) through current transformer 1067, relay 1064 and circuit breaker 1066 can be triggered in time to ensure circuit safety.

[0079] Optionally, in one embodiment, a connection portion exists between the circuit breaker 1066 and the relay 1064, and a current transformer is disposed on the connection portion. Specifically, the connection portion 122 is in the form of a copper busbar, that is, the connection portion 122 includes an input copper busbar 1076, which serves as a conductor for power transmission. The two ends of the input copper busbar 1076 are respectively connected to the input terminals of the circuit breaker 1066 and the relay 1064. By utilizing the conductivity of the copper busbar's own structure, energy loss during power transmission can be reduced, and a stable electrical connection can be provided, enhancing the overall reliability of the system.

[0080] In addition, by passing the input copper busbar 1076 through the current transformer 1067, the current transformer 1067 can detect relevant electrical parameters based on the transformer principle, mainly detecting the magnitude of the current flowing between the circuit breaker and the relay.

[0081] In one embodiment, alternatively, such as Figure 6 and Figure 7As shown, the base plate 1062 is made of metal. The strength of metal can ensure the stability and durability of the entire module. The input copper busbar 1076, relay 1064 and current transformer 1067 are pre-assembled to form a modular first module 120, which facilitates subsequent assembly with other parts. In particular, the first module 120 is suspended on the base plate 1062 by insulating pillars 116. Under the action of the insulating pillars 116, the first module 120 can be isolated from the base plate 1062, thereby preventing short circuits or leakage caused by current passing through the metal base plate and improving the safety of the system.

[0082] In one embodiment, optionally, both the first and second conductive components that realize the electrical connection between the power input module and the main circuit 104 are made of copper busbars, which have low resistance, can efficiently transmit current, and reduce energy loss. In addition, the copper busbars provide a reliable connection for power transmission, ensuring the normal operation of the main circuit 104. It can be understood that the first conductive component is a sub-copper busbar 1074, and the second conductive component is an output copper busbar 1078. The sub-copper busbar 1074 is part of the main circuit 104 and is used to transmit power. The output copper busbar 1078 is used to connect the output terminal of the relay 1064 and the sub-copper busbar 1074 of the main circuit 104, thereby realizing the electrical connection between the power input module 106 and the main circuit 104, and smoothly transmitting the power generated by the power input module 106 to the main circuit 104.

[0083] Of course, since one end of the output copper busbar 1078 is electrically connected to the output terminal of the relay 1064 and the other end is electrically connected to the sub-copper busbar 1074, this design allows the oil-electric input module 106 to be easily connected and disconnected from the main circuit 104, improving the system's flexibility and maintainability.

[0084] When the sub-copper busbar 1074 of the first conductive element and the output copper busbar 1078 of the second conductive element are connected, the power generated by the oil-electric input module 106 can be smoothly transmitted to the main circuit 104 to provide power support for the intelligent distribution box 100 and ensure its normal operation.

[0085] In one embodiment, optionally, the circuit breaker 1066 is located on the side of the first module away from the base plate, with its output terminal positioned close to the output copper busbar 1078, reducing the power transmission path and improving transmission efficiency. Based on this, by providing a connecting copper busbar 1075, the output terminal of the circuit breaker 1066 can be connected to the input copper busbar 1076. Specifically, one end of the connecting copper busbar 1075 is connected to the output terminal of the circuit breaker 1066, and the other end is connected to the input copper busbar 1076.

[0086] For the first module, the output terminal of the circuit breaker 1066 and the input copper busbar 1076 are located at opposite ends. By setting up the connecting copper busbar 1075, the two are connected together, ensuring power transmission and making the power transmission path of the entire oil-electric input module 106 more direct and efficient, thus improving the power transmission efficiency and reliability of the system. At the same time, the modular design also simplifies the system installation and maintenance process.

[0087] In one embodiment, an inlet 118 may be provided on the periphery of the enclosure 101 to provide a channel for the oil-electric input cable to enter the enclosure 101, thereby reducing the impact of the external environment on the cable.

[0088] It is understandable that some of the oil and electricity input cables pass through input port 118 and are directly connected to the input terminal of circuit breaker 1066, which simplifies the connection process and improves the convenience of installation and maintenance.

[0089] Copper busbars are metal strips made of conductive materials, usually copper, which has excellent electrical conductivity. By using copper busbars for connections, their good conductivity and heat dissipation properties can help reduce temperature under high loads, prevent overheating, and improve system safety and reliability.

[0090] In one embodiment, optionally, the mains input module 1042 is installed inside the enclosure 101. The mains input module 1042 is connected to the main circuit 104, transmitting the mains input power to the main circuit 104 for distribution to the load. Simultaneously, it is connected to the mains input cable to enable mains power access. It can be understood that in this solution, the mains input module 1042 inside the intelligent distribution box 100 can be a standard option for the entire intelligent distribution box 100, and a hybrid power input module can be optionally added on top of it.

[0091] Furthermore, the mains power input module 1042 is connected to the control board 102 via signal, and the control board 102 is used to monitor or control the mains power input module 1042.

[0092] The control board 102 can monitor and control the mains input module 1042, such as monitoring parameters like voltage, current, and frequency of the mains power, and controlling the switching state of the mains input module 1042. It can perform corresponding operations according to the mains power conditions. For example, when the mains power is normal, it controls the mains input module 1042 to conduct and supply power to the load; when the mains power is abnormal, it cuts off the mains input in time to avoid damage to the load.

[0093] The control board 102 enables automatic switching and control between mains power and generator power supply modes, improving the reliability and flexibility of power supply. In the event of a mains power failure, the generator can be started quickly to ensure continuous power supply to the load; after the mains power is restored, it can automatically switch back to mains power supply, realizing intelligent power management.

[0094] like Figure 4 As shown, a first connecting hole 1070 and a second connecting hole 1072 are respectively provided on the base plate 1062 and the housing 101. The size and shape of the first connecting hole 1070 are designed according to the connection requirements and the specifications of the fasteners. The second connecting hole 1072 is provided on the housing 101 and matches the shape and size of the first connecting hole 1070 to ensure that the fasteners can pass through smoothly and achieve connection.

[0095] The number of the first connecting hole 1070 and the second connecting hole 1072 can be reasonably distributed on the base plate 1062 according to the size and stress conditions of the base plate 1062 to ensure the stability of the connection.

[0096] Through the first connecting hole 1070 and the second connecting hole 1072, bolts, screws, and other fasteners can be used to connect the hydraulic power base plate 1062 to the second plate, making the connection between the hydraulic power base plate 1062 and the second plate detachable. This facilitates the installation and removal of the hydraulic power input module 106, and makes maintenance and replacement easier.

[0097] like Figure 5 As shown, this application provides an embodiment of a power distribution system 200. The power distribution system 200 includes an intelligent distribution box 100, a mains power input cable 202, and a fuel-powered input cable 204. The intelligent distribution box 100 receives mains power and fuel-powered input and distributes electrical energy to various load devices. The mains power input cable 202 is connected to the mains power input module 1042 of the intelligent distribution box 100, introducing mains power into the power distribution system 200 to provide regular power supply to the load devices. The fuel-powered input cable 204 is connected to the fuel-powered input module 106 of the intelligent distribution box 100, inputting electrical energy generated by a generator into the power distribution system 200 as a backup power source in the event of a mains power failure or when emergency power is required.

[0098] When the mains power is normal, the mains power input cable 202 transmits the mains power to the mains power input module 1042 of the intelligent distribution box 100. After control and distribution, it provides stable power to the load equipment.

[0099] When the mains power fails or is interrupted, the oil-electric input module 106 starts, and the oil-electric input cable 204 transmits the electrical energy generated by the generator to the intelligent distribution box 100. The intelligent distribution box 100 automatically switches to generator power supply mode to ensure the continuous operation of the load equipment.

[0100] The intelligent distribution box 100 can automatically switch between mains power and oil power to ensure the continuity and reliability of power supply.

[0101] A generator 206 is installed and connected to the power input cable 204 to transmit the generated electrical energy to the power input module 106 of the intelligent distribution box 100. In the event of a mains power failure or interruption, the generator 206 serves as a backup power source, providing power to the power distribution system 200 and ensuring the continuous operation of the load equipment. In remote areas or field work sites without mains power supply, the generator 206 can act as an independent power source, providing power to various devices.

[0102] Some portable generators 206 can be easily transported and used to provide temporary power support for outdoor activities, temporary construction sites, etc.

[0103] Understandably, depending on actual needs, different types of generators 206 can be selected, such as diesel generators, gasoline generators, wind turbines, etc.

[0104] In one specific embodiment, when installing the oil-electric input module, first remove the fixing screws and grounding copper busbar connecting screws on the generator cover plate in the enclosure to remove the generator cover plate and assemble the oil-electric input module, which includes a power connection copper busbar, a current transformer (CT), a CT metering module, a relay, an insulating column, and a support frame, etc. After installing the module into the enclosure, the signal line needs to be inserted into the signal interface to complete the communication access. Fix the first connection hole to the second connection hole of the enclosure, connect the connecting copper busbar to the sub-copper busbar to complete the power access, and the module assembly can be completed. Finally, lock the cover plate back into the enclosure and reconnect the fixing screws and grounding copper busbar connecting screws on the generator cover plate.
