TECHNICAL FIELD
[0001] The utility model relates to the field of intelligent distribution box, specifically, an intelligent distribution box. BACKGROUND
[0002] Traditional distribution box, usually only realize basic switch control function, cannot carry out real time monitoring and remote control to the running state of power equipment. Since the distribution box needs to connect multiple power equipment, generally, the power equipment connected to the distribution box all exist grounding demand, and the grounding is relatively independent, so that the wiring inside the distribution box is relatively disorderly. SUMMARY
[0003] In order to solve or improve the technical problem of the above-mentioned line connection disorder of the power load connected to the distribution box, one purpose of the utility model is to provide an intelligent distribution box.
[0004] In order to achieve the above-mentioned purpose, the utility model provides an intelligent distribution box in the first aspect, including: box, the control cavity and the connecting cavity along the first direction are arranged in the box, the connecting cavity includes the input cavity and the load cavity along the first direction, at least one input module is arranged in the input cavity;Load metering board, set in the load cavity, the load metering board includes a plurality of controllable load circuits, the controllable load circuit includes at least one circuit breaker, and the circuit breaker is used for connecting the power line of load equipment;Fire line copper bar, set in the load cavity, one end of the fire line copper bar is connected to the circuit breaker, and the fire line copper bar is used for connecting at least one fire line in the power line;Ground wire copper bar, set in the input cavity, the ground wire copper bar is connected with the wall surface of the box, and the ground wire copper bar is used for connecting the ground wire in the power line;Zero line copper bar, set in the connecting cavity, the zero line copper bar is spaced apart from the load metering board, and the zero line copper bar is used for connecting the zero line in the power line;Control panel, set in the input cavity, the control panel is used for monitoring or controlling a plurality of controllable load circuits, and the control panel is used for monitoring or controlling load equipment after the power line of load equipment is connected with at least one circuit breaker;Wherein, the ground wire copper bar is connected with the zero line copper bar or the ground wire copper bar and the zero line copper bar are insulated.
[0005] According to the intelligent distribution box provided in the application, the box body is used as the shell, and two cavities, a control cavity and a connection cavity, are arranged in the box body along the first direction, which effectively isolates the electrical components in the box body in space and avoids cross interference. The control cavity is used for arranging the control board. The control cavity is isolated from the connection cavity to ensure that the electrical signal will not be disturbed. The cavity is used to monitor and control the load circuit, and remote operation, power data acquisition, fault detection and other functions can be realized through the intelligent control board. This design provides higher intelligent management capability. The connection cavity includes an input cavity and a load cavity arranged along the first direction. The input cavity is provided with an input module to facilitate the connection of power supply equipment, such as mains, photovoltaic power generation or oil engine power generation equipment. The load cavity is provided with a load metering board to facilitate the monitoring of the controllable load circuit. In addition, the connection cavity can realize the connection of the power circuit, including the wiring of the load metering board, the controllable load circuit, the fire line, the zero line and the like. The load metering board is used to carry a plurality of controllable load circuits, and each circuit is connected with the power line of the load equipment through a circuit breaker. Through these circuits, the distribution box can monitor the power consumption, fault state and load current in real time.
[0006] The controllable load circuit can be used in cooperation with the circuit breaker to independently turn on and off the load equipment of each circuit. After the power line of the load equipment is connected with the circuit breaker, the control board can monitor or remotely control the load circuit in real time. The circuit breaker can automatically disconnect the current flow to prevent overload, short circuit or electrical fault from damaging the load equipment.
[0007] It should be emphasized that in the present scheme, the power elements for connecting the fire line, the zero line and the ground line are arranged in the form of copper bars in the box body, so that when multiple loads are connected, the cable layout in the entire box body is more clear. Specifically, the fire line copper bar is located in the load cavity and is responsible for connecting multiple power circuits, specifically connecting the fire line in the power line to the fire line copper bar through the circuit breaker. The copper bar has good conductivity and can carry a large current without overheating. The ground line copper bar connects the shell of the equipment and the grounding system of the electrical system together, and is mainly used for connecting the ground line in the power line. The ground line copper bar is connected to the wall surface of the box body through a wire to ensure good grounding of the electrical equipment and avoid safety problems such as electric shock. The role of the zero line copper bar in the intelligent distribution box is to realize the centralized connection of the zero line, which is arranged in the load cavity and spaced apart from the load metering board, so as to provide a return channel for the current loop when the zero line in the power line is connected, ensuring that the current can return to the distribution box and the power supply system smoothly under normal circumstances.
[0008] It should be noted that the arrangement of the zero line copper bar and the fire line copper bar should be kept isolated as much as possible to avoid short circuit between the two.
[0009] The control board is responsible for monitoring, managing and remotely controlling multiple controllable load circuits. The control board receives data such as current and voltage from the load metering board, and through processing and analysis of these data, the control board can implement intelligent management such as real-time monitoring of load status, fault alarm, automatic adjustment of current distribution, etc. Through the control board, users can remotely monitor or adjust the running status of power equipment through the network, improving the safety and flexibility of the power distribution system.
[0010] In addition, by allowing the ground copper bar to be selectively connected with the zero copper bar in the design, i.e. the ground copper bar can be connected with the zero copper bar, or the ground copper bar and the zero copper bar are insulated, this design can improve flexibility and ensure that the ground and zero configuration of the electrical system can meet safety standards under different operating requirements. For example, in some cases, it may be necessary to separate the ground and zero lines to avoid interference caused by current return, while in other cases, connecting the ground and zero lines can achieve a safer current return path.
[0011] In some technical solutions, optionally, the number of zero copper bars is two, and the two zero copper bars are respectively arranged on the two sides of the load metering board.
[0012] The number of zero copper bars is two, which helps to distribute the zero line of the load circuit to two different channels. This arrangement can effectively share the current load, reduce the risk of overload, and reduce the risk of overload.
[0013] When the load of the power system is high, the two zero copper bars can evenly share the current, ensuring the stability and reliability of the zero line return, and reducing the occurrence of electrical faults.
[0014] By arranging the two zero copper bars on the two sides of the load metering board, different load circuits can be connected to different zero copper bars according to actual needs, and the zero line circuit of each circuit can be more clearly separated to avoid interference between current return paths. Of course, the distribution box can more flexibly manage the current return of multiple load circuits, and in the event of a fault, it is easier to track which circuit has a problem.
[0015] In addition, when troubleshooting electrical faults, maintenance personnel can more easily check the zero line connection of each circuit. When a fault or anomaly occurs, it can quickly locate the zero line problem of which circuit, reducing maintenance time.
[0016] It can be understood that in the design of the intelligent distribution box, the number of zero copper bars is related to the carrying capacity of each copper bar. By setting two copper bars, each copper bar only needs to carry part of the current load, so that even if multiple load circuits are working at the same time, the copper bar will not overheat or be damaged due to current overload.
[0017] By configuring two zero-line copper bars, the distribution box can adapt to higher load demand, especially in industrial environments where multiple devices need to be powered simultaneously. Each copper bar can carry a larger current, preventing system instability or failure due to excessive load, allowing the intelligent distribution box to run smoothly when facing multiple device, high-power load demands, improving the scalability and adaptability of the power system.
[0018] In some technical solutions, optionally, at least part of the zero-line copper bars extend along a first direction, and the two zero-line copper bars are respectively arranged on both sides of the load metering plate in a second direction; wherein the first direction and the second direction are perpendicular.
[0019] The control cavity and the connection cavity are arranged in the box along the first direction, and reasonable functional division is made in the limited box space. Arranging two functionally different cavities along the same direction, and at least part of the zero-line copper bars extending along the first direction, adapts to the layout direction of the cavities, making the wiring of the zero-line copper bars in the box more orderly, and fully utilizing the space of the box in the first direction to avoid line crossing and confusion.
[0020] The control cavity and the connection cavity arranged along the first direction and the zero-line copper bars extending in the same direction help to reduce electromagnetic interference. The control board and other elements in the control cavity are more sensitive to the electromagnetic environment, and the power lines in the connection cavity may produce electromagnetic radiation during current transmission. Through reasonable layout, the electromagnetic interaction between the two can be minimized.
[0021] During load operation, balanced current distribution helps to reduce local overheating. If the zero-line copper bar layout is unreasonable, it may cause excessive current density in some areas, causing the copper bar to overheat, and this layout can effectively avoid such a situation, improving the reliability and safety of the entire distribution box.
[0022] In the event of a fault, such as a fault in the zero line of a load circuit, since the two zero-line copper bars are located on both sides of the load metering plate, the scope of the fault is more easily limited to one side. This helps to quickly locate the fault point and reduce the time and difficulty of troubleshooting.
[0023] For maintenance operations, technicians can more conveniently check, repair or replace the zero-line copper bars on both sides of the load metering plate. This layout makes each part relatively independent and easy to handle individually, without significantly affecting the normal operation of the other side due to operations on one side.
[0024] In some technical solutions, optionally, it includes: a first connection copper bar, one end of the first connection copper bar is connected to one zero-line copper bar, and the other end of the first connection copper bar is connected to another zero-line copper bar.
[0025] In the intelligent distribution box, two zero-line copper bars are located on both sides of the load metering panel, and a first connecting copper bar connects the two zero-line copper bars, forming a closed zero-line loop network. When the currents of different load circuits flow back through their respective connecting zero-line copper bars, the first connecting copper bar can balance the currents.
[0026] Due to the different load characteristics of different load circuits, the current distribution on each zero-line copper bar is uneven. The first connecting copper bar can redistribute the current between the two zero-line copper bars, ensuring that the current load on each zero-line copper bar is more balanced, avoiding problems such as overheating and excessive voltage drop caused by excessive current on a certain zero-line copper bar.
[0027] In some technical solutions, optionally, a second connecting copper bar is included, one end of the second connecting copper bar is connected to the zero-line copper bar or the first connecting copper bar, and the other end of the second connecting copper bar is connected to the ground copper bar.
[0028] Connecting the zero-line system and the ground copper bar achieves a certain degree of equipotential bonding. During normal operation, it helps to maintain the potential balance between different parts of the distribution box, reducing the risk of electrical accidents caused by potential differences.
[0029] By providing a fast conduction path for fault currents, the risk of electric shock is greatly reduced. In the case of personnel contacting the distribution box or its connected equipment, even if there is a leakage, the fault current will safely flow into the ground through the second connecting copper bar, rather than through the human body.
[0030] The implementation of equipotential bonding helps to reduce electrical interference and improve the overall electrical stability of the distribution box. Especially in complex electrical environments, this stability is very important for protecting sensitive equipment and ensuring the normal operation of the power system.
[0031] In some special electrical system or equipment configurations, it may be necessary to flexibly adjust the relationship between the zero-line and the ground. The presence of the second connecting copper bar allows the distribution box to meet different grounding requirements by connecting or disconnecting it according to actual needs.
[0032] In addition, for the grounding system of the entire building or industrial facility, the second connecting copper bar helps to better connect the electrical system inside the distribution box with the external grounding system. This allows the distribution box to better integrate into the grounding system of the entire electrical facility.
[0033] In some technical solutions, optionally, at least part of the live copper bars extend in a first direction, and in a second direction, the zero-line copper bars are arranged on both sides of the live copper bars.
[0034] At least part of the live copper bars extend in the first direction, consistent with the layout direction of the control cavity and the connection cavity, which helps to arrange the live line in the box in an orderly manner along the first direction. At the same time, the neutral copper bars are arranged on both sides of the live copper bars in the second direction. This layout can make full use of the space in the second direction of the box, making the wiring of live and neutral lines more compact and reasonable.
[0035] By arranging the neutral copper bars on both sides of the live copper bars, the wiring of live and neutral lines in the box can be avoided. It can be understood that the crossing of lines may cause an increase in electromagnetic interference, installation and maintenance difficulties, and other problems, and this layout effectively reduces these potential risks.
[0036] In addition, by arranging the neutral copper bars on both sides of the live copper bars in the second direction, this layout increases the electrical gap between the live and neutral lines. Sufficient electrical gap can prevent electrical breakdown between live and neutral lines in high voltage, humid or other harsh environments, ensuring the safe operation of the distribution box.
[0037] In some technical solutions, optionally, the number of power lines is three, including a first live line, a second live line, and a ground line; the first live line and the second live line are electrically connected with the circuit breakers corresponding to the two controllable load circuits, respectively, and the ground line is electrically connected with the ground copper bar.
[0038] When applied to a three-phase power system, the first live line and the second live line serve as two phases in the three-phase power, and they are electrically connected with the circuit breakers corresponding to different controllable load circuits, respectively, which can provide three-phase power supply for different load devices. By connecting the first live line and the second live line to different controllable load circuits, balanced distribution of loads among the three phases can be achieved, which helps to reduce three-phase imbalance, improve the efficiency of the power system, and reduce line loss.
[0039] The ground line is electrically connected with the ground copper bar, ensuring the grounding protection function of the entire system.
[0040] Balanced distribution of loads reduces additional line loss caused by three-phase imbalance. When the three-phase loads are balanced, the sum of the three-phase currents is close to zero, reducing the current of the neutral line and thus reducing the power loss on the line and improving the energy utilization rate of the entire power system.
[0041] In addition, even in a single-phase power system, the first live line and the second live line can be regarded as two independent single-phase power lines. This arrangement can be used to provide dual power supply for specific load devices, for example, for some important devices that cannot be interrupted, power can be obtained from two different single-phase circuits, increasing the reliability of power supply.
[0042] The first and second live wires are connected to the circuit breakers corresponding to different controllable load circuits, so that different load devices or load groups can be independently controlled. Each circuit breaker can be individually switched off or on according to the needs of the load, facilitating the management and protection of each load.
[0043] In some embodiments, the number of power lines is two, including a live wire and a ground wire; the live wire is electrically connected to the circuit breaker of a controllable load circuit, and the ground wire is electrically connected to the ground copper bar.
[0044] By connecting a live wire to a controllable load circuit and a ground wire to a ground copper bar, basic power requirements can be met while ensuring safety and controllability.
[0045] The live wire is the main line that provides power to the load device. By electrically connecting to the circuit breaker of a controllable load circuit, the power input control of the load device is achieved. After connecting to the circuit breaker, the power-on and power-off of the load device can be controlled by opening and closing the circuit breaker as needed, achieving flexible management of the load.
[0046] In some embodiments, the number of power lines is two, including a live wire and a ground wire; the live wire is electrically connected to the circuit breaker of a controllable load circuit, and the ground wire is electrically connected to the ground copper bar.
[0047] The multiple first connection holes on the live copper bar provide a clear connection point for the circuit breaker. Similarly, the multiple second connection holes on the zero copper bar and the multiple third connection holes on the ground copper bar provide convenience for connecting the corresponding lines. With the connection holes, the appropriate connection position can be selected when connecting the circuit breaker, zero line, and ground line according to actual needs.
[0048] The installer can directly insert the wiring terminals of the circuit breaker into the first connection holes of the live copper bar, and connect the zero line and the ground line to the second connection holes of the zero copper bar and the third connection holes of the ground copper bar, respectively, without the need for complex wiring operations, greatly improving the installation efficiency.
[0049] In some embodiments, the box body includes a grounding plate, and the ground copper bar is electrically connected to the grounding plate.
[0050] The grounding plate provides a dedicated grounding connection point for the distribution box. The ground copper bar is electrically connected to the grounding plate, which can ensure that the grounding system of the distribution box has good conductivity. In an electrical system, reliable grounding is a key factor in ensuring the safety of equipment and personnel. When a fault such as a leakage occurs in the distribution box, the current can be quickly conducted to the grounding plate through the ground copper bar, and then flow into the ground.
[0051] The presence of the grounding plate provides a centralized grounding path for all parts in the distribution box that need to be grounded (connected through the ground copper bar).
[0052] Once an electrical fault occurs and the device shell is electrified, the grounding system can guide the current into the ground, so that the device shell is kept at the same potential as the ground, thereby preventing people from being electrocuted. This reliable grounding connection greatly reduces the risk of electric shock for people working around the distribution box or contacting the distribution box connected device.
[0053] The additional aspects and advantages of the technical solutions of the present application will become apparent in the following description, or can be understood through practice of the present application. BRIEF DESCRIPTION OF DRAWINGS

DETAILED DESCRIPTION
[0060] In order to more clearly understand the above-mentioned purposes, features and advantages of the embodiments of the present application, the embodiments of the present application will be further described in detail below in combination with the drawings and specific embodiments. 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.
[0061] Many specific details are set forth in the following description in order to provide a thorough understanding of the present application. However, embodiments of the application can be practiced according to other embodiments that are not specifically described in the following description and exemplary implementations.
[0062] Reference will now be made to Figures 1 to 4 describing an intelligent power distribution box according to some embodiments of the present application.
[0063] As shown in Figure 1 , Figure 2 and Figure 3 , the present embodiment provides an intelligent power distribution box 100, which includes a box body 102, a load metering board 104, a live copper bar 106, a ground copper bar 108, a neutral copper bar 110, and a control board 112. Specifically, the box body 102 serves as a shell, and the interior of the box body 102 is provided with two cavities, a control cavity 1022 and a connection cavity 1024, along a first direction, which effectively isolates the electrical components located in the box body 102 in space, avoiding cross interference. The control cavity 1022 is used to accommodate the control board 112. The control cavity 1022 is isolated from the connection cavity 1024 to ensure that the electrical signals will not be disturbed. The function of this cavity is to realize the monitoring and control of the load circuit, and remote operation, power data acquisition, fault detection, etc. functions can be achieved through the intelligent control board 112. This design provides higher intelligent management capability. The connection cavity 1024 includes an input cavity 1032 and a load cavity 1034, which are also arranged along the first direction. The input cavity 1032 is provided with an input module 1033 to facilitate the connection of power supply equipment, such as mains, photovoltaic power generation or oil engine power generation, etc. The load cavity 1034 is provided with a load metering board to facilitate the monitoring of the controllable load circuit 1041 as shown in Figure 4 In addition, under the action of the connection cavity, the connection of the power circuit can be realized, including the wiring of the load metering board 104, the controllable load circuit 1041, the live line, the neutral line, etc. The load metering board 104 is used to carry a plurality of controllable load circuits 1041, and each circuit is connected to the power line of the load device through a circuit breaker 1042. Through these circuits, the power distribution box can monitor the power consumption, fault status, and load current in real time.
[0064] The controllable load circuit 1041 can independently turn on and off the load device of each circuit by cooperating with the circuit breaker 1042. After the power line of the load device is connected to the circuit breaker 1042, the control board 112 can monitor or remotely control the load circuit in real time. The circuit breaker 1042 can automatically disconnect the current flow to prevent overload, short circuit or electrical failure from damaging the load device, protect the load device and power line, and realize intelligent control functions (such as remote switching, fault detection, etc.).
[0065] It is emphasized that in the present scheme, the power elements for connecting the live wire, neutral wire, and ground wire are arranged in the form of copper bars in the box 102, so that when connecting multiple loads, the cable layout within the entire box 102 is more clear. Specifically, the live wire copper bar 106 is located in the load cavity 1034 and is responsible for connecting multiple power circuits, specifically connecting the live wire in the power line to the live wire copper bar through the circuit breaker 1042. The copper bar has good conductivity and can carry a large current without easily overheating. The ground wire copper bar 108 connects the shell of the device and the grounding system of the electrical system together, mainly used for connecting the ground wire in the power line. The ground wire copper bar 108 is connected to the wall of the box 102 through a wire, ensuring good grounding of the electrical equipment, thereby avoiding safety problems such as electric shock. The role of the neutral wire copper bar 110 in the intelligent power distribution box 100 is to realize the centralized connection of the neutral wire, which is arranged in the load cavity 1034 and is spaced apart from the load metering board, thereby providing a return channel for the current loop when the neutral wire in the power line is connected, ensuring that the current can return to the power distribution box and the power supply system smoothly under normal circumstances.
[0066] It should be noted that the arrangement of the neutral wire copper bar 110 and the live wire copper bar 106 should be kept isolated as much as possible to avoid short circuiting.
[0067] The control board 112 is responsible for monitoring, managing, and remotely controlling multiple controllable load circuits. The control board 112 receives current, voltage, and other data from the load metering board 104, and through processing and analyzing these data, the control board 112 can implement intelligent management, such as real-time monitoring of load status, fault alarm, automatic adjustment of current distribution, etc. Through the control board 112, users can remotely monitor or adjust the running status of the power equipment through the network, improving the safety and flexibility of the power distribution system.
[0068] In addition, by allowing the ground wire copper bar 108 and the neutral wire copper bar 110 to be selectively connected in the design, i.e., the ground wire copper bar can be connected to the neutral wire copper bar, or the ground wire copper bar and the neutral wire copper bar are insulated, this design can improve flexibility and ensure that the grounding and neutral wire configuration of the electrical system can meet safety standards under different operating requirements. For example, in some cases, it may be necessary to separate the ground wire and the neutral wire to avoid interference caused by current return, while in other cases, connecting the ground wire and the neutral wire can achieve a safer current return path.
[0069] In some embodiments, optionally, the number of neutral wire copper bars 110 is two, which helps to distribute the neutral wires of the load circuits to two different channels. This arrangement can effectively share the current load, reduce the risk of overload by a single copper bar carrying too much current.
[0070] When the power system load is high, the two zero-line copper bars 110 can evenly share the current, ensuring the stability and reliability of the zero-line return, and reducing the occurrence of electrical faults.
[0071] By arranging the two zero-line copper bars 110 on both sides of the load metering board 104, different load circuits can be connected to different zero-line copper bars 110 as needed, and the zero-line circuits of each circuit can be more clearly separated to avoid mutual interference of current return paths. Of course, the distribution box can more flexibly manage the current return of multiple load circuits, and it is easier to track which circuit has a problem in the event of a fault.
[0072] In addition, when troubleshooting electrical faults, maintenance personnel can more easily check the zero-line connection of each circuit. When a fault or anomaly occurs, the specific zero-line problem of the circuit can be quickly located, reducing maintenance time.
[0073] It can be understood that in the design of the intelligent distribution box 100, the number of zero-line copper bars 110 is related to the carrying capacity of each copper bar. By providing two copper bars, each copper bar only needs to carry part of the current load, so that even if multiple load circuits are working simultaneously, the copper bar will not overheat or be damaged due to excessive current.
[0074] By configuring two zero-line copper bars 110, the distribution box can adapt to higher load demands, especially in industrial environments where multiple devices need to be powered simultaneously. Each copper bar can carry more current to prevent system instability or failure due to excessive load, allowing the intelligent distribution box 100 to run smoothly when facing multiple device, high-power load demands, improving the scalability and adaptability of the power system.
[0075] In some embodiments, the control cavity 1022 and the connection cavity 1024 are arranged in the first direction within the box 102, and reasonable functional zoning is performed in the limited space of the box 102. Arranging two functionally different cavities in the same direction, and at least part of the zero-line copper bars 110 extending in the first direction, adapts to the layout direction of the cavities, making the wiring of the zero-line copper bars 110 within the box 102 more orderly, and fully utilizing the space of the box 102 in the first direction, avoiding line crossing and confusion.
[0076] The control cavity 1022 and the connection cavity 1024 arranged in the first direction and the zero-line copper bars 110 extending in the same direction help to reduce electromagnetic interference. The control board 112 and other elements in the control cavity 1022 are more sensitive to the electromagnetic environment, while the power lines in the connection cavity 1024 may generate electromagnetic radiation during current transmission. Through reasonable layout, the electromagnetic interaction between the two can be minimized.
[0077] Two neutral copper bars 110 are placed on both sides of the load metering board 104 in the second direction, balancing the current return path on both sides of the load metering board 104. Different load circuits are connected to the load metering board 104, and the current generated by these load circuits needs to return through the neutral copper bars 110. By distributing the neutral copper bars 110 on both sides, the current can be more evenly distributed around the load metering board 104.
[0078] During the operation of the load, balanced current distribution helps to reduce local overheating. If the layout of the neutral copper bars 110 is unreasonable, it may cause excessive current density in some areas, causing the copper bars to heat up, and this layout can effectively avoid this situation, improving the reliability and safety of the entire distribution box.
[0079] In the event of a fault, such as a fault in the neutral line of a certain load circuit, since the two neutral copper bars 110 are located on both sides of the load metering board 104, the impact of the fault is more easily limited to one side. This helps to quickly locate the fault point and reduces the time and difficulty of troubleshooting.
[0080] For maintenance operations, technicians can more conveniently inspect, repair, or replace the neutral copper bars 110 on both sides of the load metering board 104. This layout makes each part relatively independent and easy to handle individually, without significantly affecting the normal operation of the other side due to operations on one side.
[0081] In some embodiments, optionally, the two neutral copper bars 110 are located on both sides of the load metering board 104, and the first connecting copper bar 1142 connects the two neutral copper bars 110, forming a closed neutral line return circuit network. When the current of different load circuits returns through the neutral copper bars 110 connected to them, the first connecting copper bar 1142 can balance the current.
[0082] Since the load characteristics of different load circuits may be different, the current distribution on each neutral copper bar 110 may be uneven. The first connecting copper bar 1142 can redistribute the current between the two neutral copper bars 110, ensuring that the current load on each neutral copper bar 110 is more balanced, avoiding problems such as overheating and excessive voltage drop that may occur due to excessive current on a certain neutral copper bar 110.
[0083] In addition, if one of the neutral copper bars 110 or the neutral line of the load circuit connected to it fails (such as open circuit, poor contact, etc.), the first connecting copper bar 1142 can provide a backup current return path. Current can flow from the normal neutral copper bar 110 to the neutral line of the load circuit connected to the faulty neutral copper bar 110 through the first connecting copper bar 1142.
[0084] The first connecting copper bar 1142 connects two originally independent zero-line copper bars 110, from the perspective of the electrical system, it perfects the entire zero-line connection system. It ensures that the zero-line system can work effectively as a whole under various load operating conditions.
[0085] In some embodiments, optionally, in the distribution box, if an electrical fault occurs (such as a leakage situation), the second connecting copper bar 1144 provides a path for the fault current to flow from the zero-line system (zero-line copper bar 110 or first connecting copper bar 1142) to the ground copper bar 108. This helps to quickly introduce the fault current into the ground, thereby protecting personnel from the risk of electric shock.
[0086] Connecting the zero-line system and the ground copper bar 108 achieves a certain degree of equipotential bonding. In normal operation, it helps to maintain the potential balance between different parts of the distribution box, reducing the risk of electrical accidents that may be caused by potential differences.
[0087] By providing a quick conduction path for fault current, the risk of electric shock is greatly reduced. In the case of personnel contacting the distribution box or its connected equipment, even if a leakage occurs, the fault current will safely flow into the ground through the second connecting copper bar 1144, rather than through the human body.
[0088] The implementation of equipotential bonding helps to reduce electrical interference and improve the overall electrical stability of the distribution box. Especially in complex electrical environments, this stability is very important for protecting sensitive equipment and ensuring the normal operation of the power system.
[0089] In some special electrical system or equipment configurations, it may be necessary to flexibly adjust the relationship between the zero-line and the ground. The presence of the second connecting copper bar 1144 allows the distribution box to meet different grounding requirements by connecting or disconnecting it according to actual needs.
[0090] In addition, for the grounding system of the entire building or industrial facility, the second connecting copper bar 1144 helps to better connect the electrical system inside the distribution box with the external grounding system. This allows the distribution box to better integrate into the grounding system of the entire electrical facility.
[0091] In some embodiments, optionally, at least part of the live copper bar 106 extends in the first direction, consistent with the layout direction of the control cavity 1022 and the connection cavity 1024, which helps to orderly arrange the live line in the first direction within the box 102. At the same time, the zero-line copper bar 110 is arranged on both sides of the live copper bar 106 in the second direction. This layout can make full use of the space in the second direction of the box 102, making the wiring of live and zero lines more compact and reasonable.
[0092] By placing the neutral copper bars 110 on both sides of the hot copper bars 106, the wiring of the hot and neutral lines within the enclosure 102 can be avoided from crossing each other. It can be appreciated that line crossing can cause increased electromagnetic interference, installation and maintenance difficulties, and other issues, and this layout effectively reduces these potential risks.
[0093] The compact wiring layout allows more electrical lines to be accommodated within the limited space of the enclosure 102, making the internal structure of the distribution panel more compact, which helps to reduce the overall volume of the distribution panel or leave more space for other electrical components under the same volume.
[0094] In a distribution panel, the hot line is the current-carrying line, and a magnetic field is generated when current flows through it. By placing the neutral copper bars 110 on both sides of the hot copper bars 106, the magnetic field generated by the hot line can be shielded and offset to some extent by the neutral copper bars 110. This helps to reduce the interference of electromagnetic radiation on surrounding electrical components (such as control panels 112 and other components sensitive to the electromagnetic environment).
[0095] In addition, by placing the neutral copper bars 110 on both sides of the hot copper bars 106 in the second direction, this layout increases the electrical gap between the hot and neutral lines. Adequate electrical clearance can prevent electrical breakdown between the hot and neutral lines in high-voltage, humid or other harsh environments, ensuring the safe operation of the distribution panel.
[0096] In some embodiments, optionally, when applied to a three-phase power system, the first hot line and the second hot line serve as two phases in the three-phase power, and they are respectively electrically connected to the circuit breakers 1042 corresponding to different controllable load circuits, which can provide three-phase power supply for different load devices. By connecting the first hot line and the second hot line to different controllable load circuits, balanced distribution of loads among the three phases can be achieved, which helps to reduce three-phase imbalance, improve the efficiency of the power system, and reduce line losses.
[0097] The ground wire is electrically connected to the ground copper bar 108, ensuring the grounding protection function of the entire system.
[0098] Balanced load distribution reduces additional line losses caused by three-phase imbalance. When the three-phase load is balanced, the sum of the three-phase currents is close to zero, reducing the current of the neutral line and thus reducing the power loss on the line, improving the energy utilization rate of the entire power system.
[0099] In some embodiments, optionally, in a single-phase power system, the first hot line and the second hot line can also be regarded as two independent single-phase power lines. This arrangement can be used to provide dual power supply for specific load devices, for example, for some important devices that cannot be interrupted, power can be obtained from two different single-phase circuits, increasing the reliability of power supply.
[0100] The first and second live wires are connected to the circuit breakers 1042 corresponding to different controllable load circuits, so that different load devices or load groups can be independently controlled. Each circuit breaker 1042 can be individually turned off or turned on according to the needs of the load, facilitating the management and protection of each load.
[0101] In some embodiments, by connecting one live wire to one controllable load circuit and connecting the ground wire to the ground copper bar 108, the basic power demand can be met while ensuring safety and controllability.
[0102] The live wire is the main line that provides power to the load device. By being electrically connected to the circuit breaker 1042 of a controllable load circuit, the power input control of the load device is achieved. After being connected to the circuit breaker 1042, the power-on and power-off of the load device can be controlled by opening and closing the circuit breaker 1042 as needed, realizing flexible management of the load.
[0103] The main function of the ground wire is to connect the shell of the device and the part that may leak electricity to the ground, ensuring that when the device has a leakage fault, the current can quickly flow into the ground through the ground wire, rather than through the human body or other conductive objects, thereby ensuring personnel safety.
[0104] In some embodiments, as shown in Figure 2 and Figure 4 , a plurality of first connection holes 1062 are provided on the live copper bar 106, providing clear connection points for the circuit breakers 1042. Similarly, a plurality of second connection holes 1082 on the neutral copper bar 110 and a plurality of third connection holes 1102 on the ground copper bar 108 provide convenience for the connection of the corresponding lines. Under the action of the connection holes, when connecting the circuit breakers 1042, the neutral wire and the ground wire, the appropriate connection position can be selected according to the actual needs.
[0105] The installer can directly insert the wiring terminals of the circuit breakers 1042 into the first connection holes 1062 of the live copper bar 106, and connect the neutral wire and the ground wire to the second connection holes 1082 of the neutral copper bar 110 and the third connection holes 1102 of the ground copper bar 108, respectively, without the need for complex wiring operations, greatly improving the installation efficiency.
[0106] If it is necessary to adjust or maintain the lines in the distribution box, such as replacing the circuit breakers 1042 or rewiring, the design of multiple connection holes makes these operations more convenient. Different connection holes can be selected according to the actual situation without the need for large-scale modification of the entire copper bar.
[0107] The provision of multiple standardized connection holes helps to make the design of the distribution box comply with relevant electrical standards and specifications, and enables reliable operation in different application scenarios.
[0108] In some embodiments, as shown in Figure 3 The ground plate 116 provides a dedicated grounding connection point for the distribution box. The ground copper bar 108 is electrically connected to the ground plate 116, which ensures that the grounding system of the distribution box has good conductivity. In an electrical system, reliable grounding is a key factor in ensuring the safety of equipment and personnel. When a fault such as a leakage occurs in the distribution box, the current can be quickly conducted to the ground plate 116 through the ground copper bar 108, and then flow into the ground.
[0109] The presence of the ground plate 116 provides a centralized grounding path for all parts of the distribution box that need to be grounded (connected through the ground copper bar 108).
[0110] Once an electrical fault causes the equipment shell to be electrified, the grounding system can conduct the current into the ground, keeping the equipment shell at the same potential as the ground, thereby preventing personnel from being electrocuted. This reliable grounding connection greatly reduces the risk of personnel working around the distribution box or touching the distribution box connection equipment being electrocuted.
[0111] The connection of the ground copper bar 108 and the ground plate 116 helps to conduct electromagnetic interference signals generated in the distribution box into the ground. During the operation of electrical equipment, various electromagnetic radiation will be generated. By bypassing these interference signals to the ground through the grounding system, the electromagnetic interference on other sensitive elements (such as the control panel 112, etc.) in the distribution box can be reduced.
[0112] After the ground plate 116 is connected to the ground copper bar 108, a relatively stable electromagnetic environment can be formed inside the box body 102, which helps to improve the electromagnetic compatibility of the electrical equipment, allowing the equipment to operate stably in a normal electromagnetic environment and reducing problems such as misoperation or performance degradation caused by electromagnetic interference.
[0113] According to the intelligent distribution box provided by the utility model, in the case of connecting multiple load devices, the cable layout inside the box is more clear, and at the same time under different operation requirements, by allowing the ground copper bar and the zero copper bar to be selectively connected, the grounding and zero line configuration of the electrical system can meet the safety standards.
