Description

Technical Field

[0001] The present invention relates to the field of intelligent distribution boxes, and in particular to an intelligent distribution box and a power distribution system. Background Art

[0002] The biggest difference between smart distribution boxes and traditional distribution boxes is whether they have the ability of automation and intelligent monitoring. Traditional distribution boxes can only realize basic switch control functions and cannot monitor and remotely control the operating status of power equipment in real time. When data such as current and voltage exceed the standard, it is impossible to issue warnings and take measures in time, resulting in damage to power equipment and instability of the power system. At the same time, ordinary distribution boxes lack real-time collection and analysis of power system data and cannot effectively save energy and optimize management. In contrast, smart distribution boxes have powerful intelligent control functions in terms of automation control, real-time power monitoring, remote control, energy-saving optimization, etc. Smart distribution boxes play a vital role in home energy storage products. They provide families with safe, intelligent and efficient electricity guarantees and are key equipment for achieving stable operation and optimized management of home energy storage systems.

[0003] Currently, there are two types of smart distribution boxes. One type does not have an oil-electric input module. This type of smart distribution box can monitor and manage the electricity of the city power and the battery of the home energy storage system. However, if the power grid is interrupted and the battery of the home energy storage system is low on power, the home electrical appliances will be powered off. The other type is with an oil-electric input module. The distribution box and the oil-electric input module are deeply integrated into one. This type of smart distribution box can monitor and manage the electricity of the city power, the battery of the home energy storage system and the electricity generated by the diesel engine. Since the diesel engine generates electricity through fuel, it can cope with a variety of sudden power outages. However, the cost of this type of smart distribution box is relatively high. The oil-electric input module of this smart distribution box is a redundant module for users whose homes are not equipped with fuel engines. Users need to pay an additional fee for this. Therefore, this type of smart distribution box cannot meet the different needs of users who do not need the oil-electric input module. Summary of the invention

[0004] In order to solve or improve the above-mentioned technical problem of poor expansibility of the input module of the distribution box, an object of the present invention is to provide an intelligent distribution box.

[0005] Another object of the present invention is to provide a power distribution system.

[0006] To achieve the above-mentioned purpose, the first aspect of the present invention provides an intelligent distribution box, comprising: a box body; an oil engine accommodating chamber, which is arranged in the box body, and the oil engine accommodating chamber is used to accommodate an oil-electric input module when the intelligent distribution box expands the oil engine power generation function; a control board, which is arranged in the box body, and a first signal terminal is provided on the control board, and the first signal terminal is used to adapt to the second signal terminal of the oil-electric input module; a main circuit, which is arranged in the box body, and the main circuit is provided with a first conductive member, and the first conductive member is used to adapt to the second conductive member of the oil-electric input module; wherein the control board is used to monitor or control the oil-electric input module after the first conductive member and the second conductive member are connected and the first signal terminal and the second signal terminal are connected.

[0007] According to the intelligent distribution box provided by the present invention, an expansion interface for oil engine input and a reserved oil engine accommodating cavity are reserved before leaving the factory. When the user uses the intelligent distribution box, if the input demand for oil engine power generation is increased, the user can purchase an oil-electric input module compatible with the intelligent distribution box. By placing the oil-electric input module into the reserved oil engine accommodating cavity and connecting the relevant interface of the oil-electric input module with the reserved oil engine input expansion interface, the function of expanding the oil engine input of the intelligent distribution box can be quickly completed. The intelligent distribution box provided by the present invention utilizes the modular design of the oil-electric input module, which can quickly and conveniently realize the intelligent distribution box with the oil-electric input module installed later, and at the same time can meet the needs of different users for the oil engine power generation demand.

[0008] Through modular design, it can flexibly respond to the input needs of mains electricity and oil generators. Specifically, the intelligent distribution box includes a box body, a control panel, a main circuit and an oil-electric input module. The box body is the external structure of the intelligent distribution box. By setting an oil generator accommodating cavity inside the box body, the oil-electric input module can be accommodated when the power generation function of the intelligent distribution box is expanded, that is, when the power generation function of the oil generator is expanded. At the same time, the box body also plays a certain protective role on the internal structure, especially when the intelligent distribution box is placed in outdoor scenes. Under the action of the box body, it can effectively prevent the external environment from affecting the internal electrical components, ensuring the normal operation of the equipment under various conditions.

[0009] In addition, by installing the control board in the box, it is convenient to connect and wire with other components, and it is also protected by the box. Since the first signal terminal is set on the control board, it is connected to the second signal terminal of the oil-electric input module through the first signal terminal to realize signal transmission between the control board and the oil-electric input module, so that the control board can 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 instructions as needed to realize the start, stop, speed regulation and other functions of the oil generator.

[0010] A main circuit is arranged in the box, and a first conductive member is arranged on the main circuit to adapt to a second conductive member of the oil-electric input module. When the first conductive member and the second conductive member are connected, the electrical connection between the oil-electric input module and the main circuit is realized, so that the electric energy generated by the oil engine can be input into the distribution box.

[0011] The control board is used to control the oil-electric input module by detecting the connection status after the first conductive member and the second conductive member 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 confirms that the connection is normal, so that it can start, run and stop as needed.

[0012] In addition, the above technical solution provided by the present invention may also have the following additional technical features:

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

[0014] As an optional accessory, the oil-electric input module allows users to choose whether to equip the module according to their actual needs, so that the distribution box can 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 is used before and there is a need for oil generator power generation later, the oil-electric input module can be installed in the distribution box to meet the corresponding needs.

[0015] The above technical solution also includes: an engine cover plate, which is arranged in the box body, and the engine cover plate is detachably connected to the box body, and the engine cover plate is used to cover the engine accommodating cavity.

[0016] By providing a diesel engine cover that is detachably connected to the box, it is convenient to quickly install or remove the oil-electric input module when needed, thereby improving the flexibility and maintenance convenience of the system.

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

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

[0019] In this technical solution, the oil-electric input module includes an oil-electric base plate, a relay and a circuit breaker. The oil-electric base plate is connected to the box as a base plate. The oil-electric base plate is located at the bottom of the oil-electric input module to provide support for other components of the module. In addition, relays and circuit breakers are necessary structures of the oil-electric input module. The relay is used to control the on and off of the circuit, and the automatic switching of the circuit is achieved through the control signal to ensure a quick response when needed, providing flexibility and safety of power input. The circuit breaker is used to protect the circuit from overload or short circuit. When the current exceeds the safety limit, it automatically cuts off the circuit to prevent equipment damage and fire and other accidents, and ensure the safety of the system and users.

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

[0021] In the above technical solution, it also includes: a signal board, which is spaced apart from the oil-electric base plate, and the second signal terminal includes a 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 function of the signal board is to measure current and electric energy, to protect and control the power system, and can also be used for fault diagnosis and fault recording. Among them, the signal interface is a connection port set on the signal board for connecting 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 to realize the monitoring, control and management of the oil engine operating status.

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

[0024] By setting up a current transformer, the electrical parameters at the connection part 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 further realizing control according to the above parameters.

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

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

[0027] The circuit breaker and the relay are connected through a copper busbar. Specifically, the input copper busbar serves as a conductor for power transmission. The two ends of the input copper busbar are respectively connected to the input ends of the circuit breaker and the relay. The conductive properties of the copper busbar's own structure can reduce energy loss during power transmission, provide a stable electrical connection, and enhance 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 current flowing through the circuit breaker and the relay.

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

[0030] In this technical solution, the oil-electric baseplate is selected as a metal part. The strength of the metal can ensure the stability and durability of the entire module. The input copper bus, relay and current transformer are pre-assembled to form a modular first module to facilitate subsequent assembly with other parts. In particular, the first module is suspended on the oil-electric baseplate through insulating columns, that is, the first module can be isolated from the oil-electric baseplate under the action of the insulating columns, thereby preventing current from passing through the metal baseplate to cause short circuit or leakage, thereby improving the safety of the system.

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

[0032] The first conductive member and the second conductive member for realizing the electrical connection between the oil-electric input module and the main circuit are both in the form of copper bars, which have low resistance, can efficiently transmit current, and reduce energy loss. In addition, the copper bar provides a reliable connection for power transmission to ensure the normal operation of the main circuit. It can be understood that the first conductive member is a sub-copper bar, and the second conductive member is an output copper bar, wherein the sub-copper bar is used to transmit power as part of the main circuit, and the output copper bar is used to connect the output end of the relay and the sub-copper bar of the main circuit, thereby realizing the power connection between the oil-electric input module and the main circuit, and smoothly transmitting the power generated by the oil-electric input module to the main circuit.

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

[0034] When the sub-copper busbar of the first conductive part and the output copper busbar of the second conductive part are connected, the electricity 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 arranged on a side of the first module away from the oil-electric base plate, and the output end of the circuit breaker is arranged close to the output copper busbar. The oil-electric input module also includes: a connecting copper busbar, which is arranged 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 solution, the circuit breaker is set on the side of the first module away from the oil-electric base plate, and the output end is set close to the output copper bar, which reduces the power transmission path and improves the transmission efficiency. On this basis, by setting a connecting copper bar, the output end of the circuit breaker can be connected to the input copper bar. Specifically, one end of the connecting copper bar is connected to the output end of the circuit breaker, and the other end is connected to the input copper bar.

[0037] For the first module, the output end of the circuit breaker and the input copper bar are at opposite ends. By setting a connecting copper bar, the two are connected together to ensure power transmission, and make the power transmission path of the entire oil-electric input module more direct and efficient, thereby improving the power transmission efficiency and reliability of the system. At the same time, the modular design also simplifies the installation and maintenance process of the system.

[0038] In the above technical solution, it also includes: an input port, which is arranged on the peripheral wall of the box body, and part of the oil and electricity input cables pass through the opening and are connected to the input end of the circuit breaker.

[0039] An input port is provided on the peripheral wall of the box body to provide a passage for the oil and electricity input cables to enter the box body, thereby reducing the impact of the external environment on the cables.

[0040] It can be understood that part of the oil-electric input cables are directly connected to the input end of the circuit breaker through the input port, which simplifies the connection process and improves the convenience of installation and maintenance.

[0041] The above technical solution also includes: a first connection hole, which is arranged on the oil-electric base plate; and a second connection hole, which is arranged on the box body; wherein the connection between the oil-electric base plate and the box body is realized through the first connection hole and the second connection hole.

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

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

[0044] By installing the mains input module in the box, the mains input module is connected to the main circuit, and the power input from the mains is transmitted to the main circuit, and then distributed to the load. At the same time, it is connected to the mains input cable to achieve the access to the mains. It can be understood that in this solution, the mains input module in the intelligent distribution box can be used as a standard option for the entire intelligent distribution box, and the oil-electric input module can be optionally added on this basis.

[0045] Furthermore, the mains input module is signal-connected to the control panel, and the control panel is used to monitor or control the mains input module.

[0046] Among them, the control board can monitor and control the AC power input module, such as monitoring the voltage, current, frequency and other parameters of the AC power, and controlling the switching state of the AC power input module. It can perform corresponding operations according to the AC power situation. For example, when the AC power is normal, the AC power input module is controlled to be turned on to supply power to the load; when the AC power is abnormal, the AC power input is cut off in time to avoid damage to the load.

[0047] The control panel can realize the automatic switching and control of the two power supply modes of mains power and diesel generator, which improves the reliability and flexibility of power supply. In case of mains power failure, the diesel generator can be started quickly to ensure the continuous power supply of the load; after the mains power is restored, it can automatically switch back to the mains power supply, realizing intelligent power management.

[0048] The second aspect of the present invention provides a power distribution system, comprising: any one of the above-mentioned intelligent distribution boxes; a mains input cable connected to the mains input module of the intelligent distribution box; and an oil-to-electricity input cable connected to the oil-to-electricity input module of the intelligent distribution box.

[0049] According to the technical solution of the power distribution system of the present invention, the power distribution system includes an intelligent distribution box, a mains input cable and an oil-electric input cable. The intelligent distribution box is used to receive the mains input and the oil-electric input, and distribute the electric energy to each load device. The mains input cable is connected to the mains input module of the intelligent distribution box, and the mains is introduced into the power distribution system to provide a conventional power supply for the load device. The oil-electric input cable is connected to the oil-electric input module of the intelligent distribution box. When the mains fails or emergency power supply is required, the electric energy generated by the oil generator is input into the power distribution system as a backup power supply.

[0050] Additional aspects and advantages of the technical solutions of the present invention will become apparent in the following description or will be understood through the practice of the present invention. BRIEF DESCRIPTION OF THE DRAWINGS

[0061] In order to more clearly understand the above-mentioned purposes, features and advantages of the embodiments of the present invention, the embodiments of the present invention are further described in detail below in conjunction with the accompanying drawings and specific implementation methods. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

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

[0063] An existing intelligent distribution box does not have an oil-electric input module. This intelligent distribution box can monitor and manage the electricity of the city power and the battery of the home energy storage system. However, if the power grid is interrupted and the battery of the home energy storage system is low on power, the home electrical appliances will be powered off. Another existing type is with an oil-electric input module. The distribution box and the oil-electric input module are deeply integrated into one. This intelligent distribution box can monitor and manage the electricity of the city power, the battery of the home energy storage system and the electricity generated by the oil engine. Since the oil engine generates electricity through fuel, it can cope with a variety of sudden power outages. However, the cost of this intelligent distribution box is relatively high. The oil-electric input module of this intelligent distribution box is a redundant module for users whose homes are not equipped with fuel engines. Users need to pay an additional fee for this. Therefore, this intelligent distribution box cannot meet the different needs of various users who do not need the oil-electric input module.

[0064] Refer to the following Figures 1 to 7 An intelligent distribution box and a power distribution system provided according to some embodiments of the present invention are described.

[0065] In view of this, if Figure 1 , Figure 2 and Figure 3 As shown, the present invention proposes a new intelligent distribution box 100, including: a box body 101; an oil engine accommodating chamber 1012, which is arranged in the box body 101, and the oil engine accommodating chamber 1012 is used to accommodate an oil-electric input module 106 when the intelligent distribution box 100 expands the oil engine power generation function; a control board 102, which is arranged in the box body 101, and a first signal terminal is provided on the control board 102, and the first signal terminal is used to adapt to the second signal terminal 1104 of the oil-electric input module 106; a main circuit 104, which is arranged in the box body 101, and the main circuit 104 is provided with a first conductive member, and the first conductive member is used to adapt to the second conductive member of the oil-electric input module 106; wherein the control board 102 is used to monitor or control the oil-electric input module 106 after the first conductive member and the second conductive member are connected and the first signal terminal and the second signal terminal 1104 are connected.

[0066] The intelligent distribution box 100 provided by the present invention has a reserved expansion interface for oil engine input and a reserved oil engine accommodating cavity 1012 before leaving the factory. When the user uses the intelligent distribution box 100, if the input demand for oil engine power generation is increased, the user can purchase an oil-electric input module compatible with the intelligent distribution box 100. By placing the oil-electric input module into the reserved oil engine accommodating cavity 1012 and connecting the relevant interface of the oil-electric input module with the reserved oil engine input expansion interface, the function of expanding the oil engine input of the intelligent distribution box 100 can be quickly completed. The intelligent distribution box 100 provided by the present invention utilizes the modular design of the oil-electric input module, which can quickly and conveniently realize the intelligent distribution box 100 after-installing the oil-electric input module, and at the same time can meet the needs of different users for oil engine power generation.

[0067] Through modular design, it can flexibly respond to the input requirements of the mains and the oil generator. Specifically, the intelligent distribution box 100 includes a box body 101, a control board 102, a main circuit 104 and an oil-electric input module 106. The box body 101 is the external structure of the intelligent distribution box 100. By setting an oil generator accommodating chamber 1012 inside the box body 101, the oil-electric input module 106 can be accommodated when the power generation function of the intelligent distribution box 100 is expanded, that is, when the power generation function of the oil generator is expanded. At the same time, the box body 101 also plays a certain protective role on the internal structure, especially when the intelligent distribution box 100 is placed in an outdoor scene, the box body 101 can effectively prevent the external environment from affecting the internal electrical components, ensuring that the equipment works normally under various conditions.

[0068] In addition, by installing the control board 102 in the box body 101, it is convenient to connect and wire with other components, and it is also protected by the box body 101. Since the first signal terminal is set on the control board 102, it is connected to the second signal terminal 1104 of the oil-electric input module 106 through the first signal terminal to realize signal transmission between the control board 102 and the oil-electric input module 106, so that the control board 102 can 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 instructions as needed to realize the start, stop, speed regulation and other functions of the oil engine power generation.

[0069] A main circuit 104 is arranged in the box body 101. A first conductive member is arranged on the main circuit 104 to adapt to a second conductive member of the oil-electric input module 106. When the first conductive member and the second conductive member are connected, the electrical connection between the oil-electric input module 106 and the main circuit 104 is achieved, so that the electric energy generated by the oil engine can be input into the distribution box.

[0070] The control board 102 is used to control the oil-electric input module 106 by detecting the connection status after the first conductive member 1122 and the second conductive member 1124 are connected and the first signal terminal 1102 is connected to the second signal terminal 1104, and when the oil-electric input module 106 is connected to the distribution box, so that the oil-electric input module 106 can be started, run and stopped as needed after confirming that the connection is normal.

[0071] Therein, an oil engine cover plate 108 detachably connected to the box body 101 is also provided, so as to facilitate the rapid installation or removal of the oil-electric input module 106 when necessary, thereby improving the flexibility and maintenance convenience of the system.

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

[0073] In one embodiment, the oil-electric input module 106 is an optional component, so that the user can choose whether to equip the oil-electric input module 106 according to their actual needs, so that the distribution box can 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 is previously used and there is a need for oil generator power generation later, 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 oil-electric input module 106 includes an oil-electric base plate 1062, a relay 1064 and a circuit breaker 1066. The oil-electric base plate 1062 is connected to the box 101 as a base plate. The oil-electric base plate 1062 is located at the bottom of the oil-electric input module 106 to provide support for other components of the module. In addition, the relay 1064 and the circuit breaker 1066 are both necessary structures of the oil-electric input module 106, wherein the relay 1064 is used to control the on and off of the circuit, and realizes automatic switching of the circuit through the control signal to ensure rapid response when needed, providing flexibility and safety of power input. The circuit breaker 1066 is used to protect the circuit from overload or short circuit. When the current exceeds the safety limit, the circuit is automatically cut off to prevent equipment damage and accidents such as fire, and to ensure the safety of the system and users.

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

[0076] In one embodiment, optionally, 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 function of the signal board 1068 is to measure current and electric energy, to protect and control the power system, and can also be used for fault diagnosis and fault recording. Among them, the signal interface 1069 is a connection port set on the signal board 1068, which is used to connect external devices or lines. The second signal terminal includes the signal interface 1069, through which the oil-electric input module 106 can communicate and transmit data with other devices to realize the monitoring, control and management of the oil engine operation status.

[0077] In one embodiment, a current transformer 1067 is optionally provided to effectively collect electrical parameters at the connection portion 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 signals, thereby monitoring the electrical parameters and further realizing control according to the above parameters.

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

[0079] In one embodiment, optionally, there is a connection portion between the circuit breaker 1066 and the relay 1064, and the current transformer is arranged 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, and the input copper busbar 1076 serves as a conductor for power transmission. The two ends of the input copper busbar 1076 are respectively connected to the input ends of the circuit breaker 1066 and the relay 1064. By utilizing the conductive properties of the copper busbar's own structure, the energy loss in the power transmission process can be reduced, and a stable electrical connection can be provided to enhance the overall reliability of the system.

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

[0081] In one embodiment, optionally, Figure 6 and Figure 7As shown, the oil-electric base plate 1062 is selected as a metal part. The strength of the metal can ensure the stability and durability of the entire module. The input copper bus 1076, the relay 1064 and the current transformer 1067 are pre-assembled to form a modular first module 120, which is convenient for subsequent assembly with other parts. In particular, the first module 120 is suspended on the oil-electric base plate 1062 through the insulating column 116, that is, the first module 120 can be isolated from the oil-electric base plate 1062 under the action of the insulating column 116, thereby preventing the current from passing through the metal base plate to cause a short circuit or leakage, thereby improving the safety of the system.

[0082] In one embodiment, optionally, the first conductive member and the second conductive member for realizing the electrical connection between the oil-electric input module and the main circuit 104 are both in the form of copper bars, which have low resistance, can efficiently transmit current, and reduce energy loss. In addition, the copper bar provides a reliable connection for power transmission to ensure the normal operation of the main circuit 104. It can be understood that the first conductive member is a sub-copper bar 1074, and the second conductive member is an output copper bar 1078, wherein the sub-copper bar 1074 is used to transmit power as part of the main circuit 104, and the output copper bar 1078 is used to connect the output end of the relay 1064 and the sub-copper bar 1074 of the main circuit 104, thereby realizing the power connection between the oil-electric input module 106 and the main circuit 104, and smoothly transmitting the power generated by the oil-electric input module 106 to the main circuit 104.

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

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

[0085] In one embodiment, optionally, the circuit breaker 1066 is arranged on a side of the first module away from the oil-electric base plate, and the output end is arranged close to the output copper bar 1078, thereby reducing the power transmission path and improving the transmission efficiency. On this basis, by setting the connecting copper bar 1075, the output end of the circuit breaker 1066 can be connected to the input copper bar 1076. Specifically, one end of the connecting copper bar 1075 is connected to the output end of the circuit breaker 1066, and the other end is connected to the input copper bar 1076.

[0086] For the first module, the output end of the circuit breaker 1066 and the input copper bar 1076 are at opposite ends. The connecting copper bar 1075 is provided to connect the two together to ensure power transmission, and make the power transmission path of the entire oil-electric input module 106 more direct and efficient, thereby improving the power transmission efficiency and reliability of the system. At the same time, the modular design also simplifies the installation and maintenance process of the system.

[0087] In one embodiment, optionally, an input port 118 is provided on the peripheral wall of the box 101 to provide a passage for the oil and electricity input cables to enter the box 101 and reduce the impact of the external environment on the cables.

[0088] It can be understood that part of the oil-electric input cables pass through the input port 118 and are directly connected to the input end of the 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, with good electrical conductivity. By using copper busbars for connection, the good electrical conductivity and heat dissipation properties of copper busbars can be used to help reduce the temperature under high load conditions, prevent overheating, and improve the safety and reliability of the system.

[0090] In one embodiment, optionally, a mains input module 1042 is installed in the box 101, and the mains input module 1042 is connected to the main circuit 104, and the electric energy inputted from the mains is transmitted to the main circuit 104, and then distributed to the load for use. At the same time, it is connected to the mains input cable to achieve access to the mains. It can be understood that in this solution, the mains input module 1042 in the intelligent distribution box 100 can be used as a standard option for the entire intelligent distribution box 100, and an oil-electric input module can be optionally added on this basis.

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

[0092] Among them, the control board 102 can monitor and control the AC power input module 1042, such as monitoring the voltage, current, frequency and other parameters of the AC power, and controlling the switching state of the AC power input module 1042, and can perform corresponding operations according to the situation of the AC power. For example, when the AC power is normal, the AC power input module 1042 is controlled to be turned on to supply power to the load; when the AC power is abnormal, the AC power input is cut off in time to avoid damage to the load.

[0093] Under the control of the control panel 102, the automatic switching and control of the two power supply modes of mains power and diesel generator can be realized, thereby improving the reliability and flexibility of power supply. When the mains power fails, the diesel 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 the mains power supply, thus realizing intelligent power management.

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

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

[0096] Through the first connection hole 1070 and the second connection hole 1072, the oil-electric base plate 1062 can be connected to the second plate body by bolts, screws or other fixings, so that the connection between the oil-electric base plate 1062 and the second plate body is detachable. This facilitates the installation and removal of the oil-electric input module 106, and is convenient for maintenance and replacement.

[0097] like Figure 5 As shown, the present application provides an embodiment of a power distribution system 200, which includes an intelligent distribution box 100, a mains input cable 202, and an oil-electric input cable 204. The intelligent distribution box 100 is used to receive mains input and oil-electric input, and distribute electric energy to various load devices. The mains input cable 202 is connected to the mains input module 1042 of the intelligent distribution box 100, and the mains power is introduced into the power distribution system 200 to provide a conventional power supply for the load devices. The oil-electric input cable 204 is connected to the oil-electric input module 106 of the intelligent distribution box 100. When the mains power fails or emergency power supply is required, the electric energy generated by the oil generator is input into the power distribution system 200 as a backup power supply.

[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, and after control and distribution, provides stable power for the load equipment.

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

[0100] The intelligent distribution box 100 can realize automatic switching between mains power and oil power, ensuring the continuity and reliability of power supply.

[0101] A generator 206 is provided, and the generator 206 is connected to the oil-electric input cable 204, and the generated electric energy is transmitted to the oil-electric input module 106 of the intelligent distribution box 100. When the mains fails or is interrupted, the generator 206 serves as a backup power source to provide electric energy for the power distribution system 200 to ensure the continuous operation of the load equipment. In remote areas or field work sites without mains supply, the generator 206 can be used as an independent power source to provide power for various equipment.

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

[0103] It is understandable that different types of generators 206 can be selected according to actual needs, such as a diesel generator, a gasoline generator, a wind generator, etc.

[0104] In a specific embodiment, when installing the oil-electric input module, first remove the fixing screws on the oil engine cover plate in the box and the connecting screws of the ground copper busbar, then remove the oil engine cover plate, and assemble the oil-electric input module, which includes a copper busbar for connecting power, a current transformer (CT), a CT metering module, a relay, an insulating column, and a support frame, etc.; after the module is installed into the chassis, it is necessary to insert the signal line into the signal interface to complete the communication access, fix the first connecting hole on the second connecting hole of the chassis, connect the connecting copper busbar to the sub-copper busbar, complete the power access, and realize the assembly of the module. Finally, lock the cover plate back to the chassis, and reconnect the fixing screws on the oil engine cover plate and the connecting screws of the ground copper busbar.

[0105] The intelligent distribution box and the power distribution system provided by the present invention can flexibly respond to the input requirements of the mains electricity and the diesel generator through modular design.
