Description

Technical Field

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

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

[0003] Currently, smart distribution boxes are divided into two types. One type does not include a generator. This type of smart distribution box can monitor and manage the power from the mains and the home energy storage system's batteries. However, if there is a grid interruption and the home energy storage system's batteries are low on power, household appliances will lose power. The other type includes a generator, with the distribution box and generator deeply integrated into one unit. This type of smart distribution box can monitor and manage the power from the mains, the home energy storage system's batteries, and the power generated by the generator. Since the generator generates electricity from fuel, it can cope with various sudden power outages. However, this type of smart distribution box is more expensive. For users whose homes do not have a fuel engine, the generator is a redundant module, requiring users to pay an additional fee. Therefore, this type of smart distribution box cannot well meet the different needs of users who require and do not require a generator. Utility Model Content

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

[0005] Another objective of this utility model is to provide a distribution box.

[0006] To achieve the above objectives, the first aspect of this utility model provides a generator device as an optional accessory for a power distribution box. The power distribution box includes a main circuit and a control board. The generator device includes: a power distribution base plate; a relay disposed on the power distribution base plate, one end of which is used to connect to the main circuit of the power distribution box; and a signal board disposed on the power distribution base plate, the signal board having a signal interface for communication connection with the control board.

[0007] The generator device provided by this utility model is mainly used to expand the function of a power distribution box. The generator device includes a base plate, relays, and a signal board. The base plate, as the foundation plate, is located at the bottom of the generator device and provides support for other components of the module. Furthermore, the relays are used to control the on / off state of the circuit, achieving automatic switching of the circuit through control signals to ensure rapid response when needed, providing flexibility and safety for power input. The signal board is mainly used for communication, exchanging acquired information with the power distribution box, specifically including fault diagnosis and fault recording. The signal interface is a connection port on the signal board used to connect external devices or lines.

[0008] It is important to emphasize that the generator unit is an optional accessory for the distribution box in this solution, allowing users to choose whether to equip it with the generator unit according to their actual needs. This enables the distribution box to better meet the diverse needs of different users. In special scenarios, such as temporary power outages due to weather, or when the power supply was previously mains power and there is a need for generator power generation, the generator unit can be installed in the distribution box to meet the corresponding needs.

[0009] Furthermore, signal boards can be spaced out on the hydraulic base plate to avoid mutual interference.

[0010] The input cable can be directly connected to the relay, or it can be indirectly connected to the relay through other electronic components.

[0011] In addition, the above-mentioned technical solution provided by this utility model may also have the following additional technical features:

[0012] The above technical solution also includes: a circuit breaker, which is electrically connected to a relay, with the other end of the relay connected to the circuit breaker, and one end of the circuit breaker used to connect the oil-electric input cable.

[0013] In this solution, circuit breakers are primarily used to protect the circuit from overload or short circuits. When the current exceeds safe limits, the circuit is automatically disconnected to prevent equipment damage and fires, ensuring the safety of the system and users. It should be noted that the circuit breaker is electrically connected to the relay, and the power input cable is directly connected to the circuit breaker. Power is then transferred through the electrical connection between the circuit breaker and the relay.

[0014] The above technical solution also includes: a current transformer, located at the connection between the relay and the circuit breaker, the current transformer being used to collect electrical parameters at the connection.

[0015] By setting up a current transformer, electrical parameters at the connection point between the relay and the circuit breaker can be effectively collected. Specifically, the electrical parameters include power, current, voltage, etc. The signal board can transmit the electrical parameters collected by the current transformer to the control board through signals, thereby realizing the monitoring of the electrical parameters and then realizing control based on the above parameters.

[0016] For example, by detecting abnormal currents (such as overload or short circuit) through current transformers, relays and circuit breakers can be triggered in a timely manner to ensure circuit safety.

[0017] In the above technical solution, the connection part includes: an input copper busbar, one end of which is electrically connected to the output terminal of the circuit breaker, and the other end of which is electrically connected to the input terminal of the relay. The input copper busbar passes through the current transformer.

[0018] A copper busbar is used to connect the circuit breaker and the relay. Specifically, the input copper busbar serves as the conductor for power transmission. The two ends of the input copper busbar are connected to the output terminal of the circuit breaker and the input terminal of the relay, respectively. By utilizing the conductivity of the copper busbar's structure, energy loss during power transmission can be reduced, and a stable electrical connection can be provided, thereby enhancing the overall reliability of the system.

[0019] In addition, the input copper busbar passes through the current transformer, which can detect relevant electrical parameters based on the transformer principle, mainly detecting the magnitude of the current flowing between the circuit breaker and the relay.

[0020] In the above technical solution, the base plate of the oil-electric system is a metal part, and the input copper busbar, relay and current transformer are assembled into the first module. The oil generator device also includes an insulating column, which is set on the base plate of the oil-electric system, and one end of the insulating column is connected to the first module.

[0021] In this technical solution, the base plate is made of metal. The strength of metal can ensure the stability and durability of the entire module. The input copper busbar, relay and current transformer are pre-assembled to form a modular first module, which facilitates the subsequent assembly with other parts. In particular, the first module is suspended on the base plate by insulating pillars. The insulating pillars can isolate the first module from the base plate, thereby preventing short circuits or leakage caused by current passing through the metal base plate and improving the safety of the system.

[0022] The above technical solution includes: an output copper busbar, one end of which is electrically connected to the output terminal of the relay, and the other end of which is electrically connected to the sub-copper busbar of the main circuit.

[0023] The electrical connection between the generator and the main circuit is achieved using copper busbars, which have low resistance, enabling efficient current transmission and reducing energy loss. Furthermore, the copper busbars provide a reliable connection for power transmission, ensuring the normal operation of the main circuit. The sub-copper busbars, as part of the main circuit, are used to transmit power, while the output copper busbars connect the relay output terminals to the sub-copper busbars of the main circuit, thus realizing the electrical connection between the generator and the main circuit and smoothly transmitting the power generated by the generator to the main circuit.

[0024] Of course, since one end of the output copper busbar is electrically connected to the output terminal of the relay and the other end is electrically connected to the sub-copper busbar, this design allows the generator to be easily connected and disconnected from the main circuit, improving the system's flexibility and maintainability.

[0025] When the sub-copper busbar of the first conductive element and the output copper busbar of the second conductive element are connected, the power generated by the generator can be smoothly transmitted to the main circuit, providing power support to the distribution box and ensuring its normal operation.

[0026] In the above technical solution, the circuit breaker is located on the side of the first module away from the base plate of the oil and electricity system, and the output end of the circuit breaker is located close to the output copper busbar. The generator also includes a connecting copper busbar, located between the circuit breaker and the first module, with one end of the connecting copper busbar connected to the output end of the circuit breaker and the other end of the connecting copper busbar connected to the input copper busbar.

[0027] In this design, the circuit breaker is positioned on the side of the first module furthest from the base plate, with its output terminal close to the output copper busbar. This reduces the power transmission path and improves transmission efficiency. Furthermore, a connecting copper busbar connects the circuit breaker's output terminal to the input copper busbar. Specifically, one end of the connecting copper busbar is connected to the circuit breaker's output terminal, and the other end is connected to the input copper busbar.

[0028] For the first module, the output terminal of the circuit breaker and the input copper busbar are located at opposite ends. By setting up connecting copper busbars, the two are connected together, ensuring power transmission and making the power transmission path of the entire generator unit more direct and efficient, thus improving the system's power transmission efficiency and reliability. At the same time, the modular design also simplifies the system's installation and maintenance process.

[0029] The above technical solution also includes: a first connection hole, provided on the base plate of the electric power supply, the first connection hole being used to adapt to the second connection hole of the distribution box; wherein, the connection between the base plate of the electric power supply and the distribution box is realized through the first connection hole and the second connection hole.

[0030] In this technical solution, a first connecting hole and a second connecting hole are respectively provided at the relative positions of the base plate and the distribution box. The size and shape of the first connecting hole are designed according to the connection requirements and the specifications of the fasteners. The second connecting hole can be set on the distribution box body as needed, matching the shape and size of the first connecting hole to ensure that the fasteners can pass through smoothly and achieve connection.

[0031] The second aspect of this utility model provides a power distribution box, comprising: a box body, wherein a control board and a main circuit are provided inside the box body; a generator housing cavity, disposed inside the box body, wherein the generator housing cavity is used to accommodate a generator device as described above when the power distribution box expands its generator power generation function; wherein the control board is used to monitor or control the generator device after the main circuit and the relay are electrically connected and the signal board is communicatively connected to the control board.

[0032] According to the technical solution of the distribution box of this utility model, an expansion interface for generator input and a reserved generator housing cavity can be reserved before leaving the factory. If the user needs to increase the input of generator power generation during the use of the distribution box, the user can purchase a generator device compatible with the distribution box separately. By placing the generator device into the reserved generator housing cavity and connecting the relevant interfaces of the generator device to the reserved generator input expansion interface, the function of expanding the generator input of the distribution box can be quickly completed. The distribution box provided by this utility model utilizes the modular design of the generator device, which allows for quick and convenient installation of a generator device after the distribution box is installed, and at the same time, it can meet the needs of different users for generator power generation.

[0033] The enclosure serves as the external structure of the distribution box. By setting up a generator housing cavity inside the enclosure, it can accommodate the generator device when the power generation function of the distribution box is expanded, i.e., when the generator generation function is expanded. At the same time, the enclosure also plays a certain role in protecting the internal structure. Especially when the distribution box is placed outdoors, the enclosure can effectively prevent the external environment from affecting the internal electrical components, ensuring that the equipment works normally under various conditions.

[0034] Furthermore, by installing the control board inside the enclosure, it is easy to connect and wire to other components, while also being protected by the enclosure. The control board communicates with the generator unit to enable signal transmission, allowing the control board to control the generator unit. This ensures that the control board can accurately obtain the status information of the generator unit and issue control commands as needed to realize functions such as starting, stopping, and speed regulation of the generator.

[0035] The main circuit is installed inside the box, and the electrical energy generated by the generator can be input into the distribution box by realizing the electrical connection between the generator and the main circuit.

[0036] The control board is used to control the generator unit after it is connected to the distribution box by detecting the connection status and confirming that the connection is normal, so that it can start, run and stop as needed.

[0037] The above technical solution also includes: an input port, located on the periphery of the housing, through which part of the oil and electricity input cable is connected to the oil generator.

[0038] By setting inlet ports on the perimeter walls of the enclosure, a channel is provided for the oil and electricity input cables to enter the enclosure, reducing the impact of the external environment on the cables.

[0039] It is understandable that some of the oil and electricity input cables pass through the input port and are directly connected to the input terminal of the circuit breaker, which simplifies the connection process and improves the convenience of installation and maintenance.

[0040] Additional aspects and advantages of the present invention will become apparent in the following description or may be learned by practice of the present invention. Attached Figure Description

Detailed Implementation

[0049] To better understand the above-mentioned objectives, features, and advantages of the embodiments of this utility model, the embodiments of this utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0050] Many specific details are set forth in the following description in order to provide a full understanding of this application. However, embodiments of the present invention may also be implemented in other ways different from those described herein. Therefore, the scope of protection of this application is not limited to the specific embodiments disclosed below.

[0051] One existing type of smart distribution box does not include a generator. This type of smart distribution box can monitor and manage the power from the mains and the home energy storage system's batteries. However, if there is a grid interruption and the home energy storage system's batteries are low on power, the household appliances will lose power. Another existing type includes a generator, where the distribution box and generator are deeply integrated into one unit. This type of smart distribution box can monitor and manage the power from the mains, the home energy storage system's batteries, and the power generated by the generator. Since the generator generates electricity from fuel, it can cope with various sudden power outages. However, this type of smart distribution box is more expensive. The generator unit in this smart distribution box is a redundant module for users whose homes do not have a fuel engine, requiring them to pay an additional fee. Therefore, this type of smart distribution box cannot well meet the different needs of users who require and do not require a generator.

[0052] The following reference Figures 1 to 6 This invention describes a generator device and a power distribution box provided according to some embodiments of the present invention.

[0053] In view of this, such as Figure 1 , Figure 2 and Figure 3As shown, this utility model proposes a generator device 106, which can be used as an optional accessory for the distribution box. This allows users to choose whether to equip the distribution box with the generator device 106 according to their actual needs, thereby enabling the distribution box to better meet the diverse needs of different users. In special scenarios, such as temporary power outages due to weather, or when the distribution box previously used mains power and now requires generator power generation, the generator device 106 can be installed in the distribution box to meet the corresponding needs.

[0054] Specifically, such as Figure 4 As shown, the generator unit 106 includes a base plate 1062, a relay 1064, and a signal board 1068. The base plate 1062 serves as the foundation plate, located at the bottom of the generator unit 106, providing support for other components of the module. Furthermore, the relay 1064 controls the on / off state of the circuit, achieving automatic switching of the circuit through control signals to ensure rapid response when needed, providing flexibility and safety in power input. The signal board 1068 is mainly used for communication, exchanging acquired information with the distribution box 100, specifically including fault diagnosis and fault recording. The signal interface 1069 is a connection port on the signal board 1068, used to connect external devices or lines.

[0055] It should be emphasized that the generator unit 106 in this solution is an optional accessory of the distribution box 100, allowing users to choose whether to equip it with the generator unit 106 according to their actual needs. This enables the distribution box 100 to better meet the diverse needs of different users. In special scenarios, such as temporary power outages due to weather, or when the mains power supply was previously used and there is a need for generator power generation, the generator unit 106 can be installed in the distribution box 100 to meet the corresponding needs.

[0056] Furthermore, the signal board 1068 can be spaced apart on the hydraulic base plate 1062 to avoid mutual interference.

[0057] The input cable can be directly connected to the relay, or it can be indirectly connected to the relay through other electronic components.

[0058] In one embodiment, optionally, a circuit breaker 1066 is provided, primarily for circuit protection against overload or short circuit. When the current exceeds a safe limit, it automatically disconnects the circuit to prevent equipment damage and fires, ensuring the safety of the system and users. It should be noted that the circuit breaker 1066 is electrically connected to the relay 1064, and the power input cable is directly connected to the circuit breaker 1066. Power is then transferred through the electrical connection between the circuit breaker 1066 and the relay 1064.

[0059] The oil-electric input cable connects an external oil power source to the module, ensuring that power can be smoothly input into the module and effectively utilizing the generator's power generation function.

[0060] In one embodiment, optionally, a current transformer 1067 is provided, which can effectively collect electrical parameters at the connection between the relay and the circuit breaker. Specifically, the electrical parameters include power, current, voltage, etc. The signal board 1068 can transmit the electrical parameters collected by the current transformer 1067 to the control board 102 through a signal, thereby realizing the monitoring of the electrical parameters and then realizing control based on the above parameters.

[0061] For example, by detecting abnormal current (such as overload or short circuit) through current transformer 1067, relay 1064 and circuit breaker 1066 can be triggered in time to ensure circuit safety.

[0062] Optionally, in one embodiment, a connection portion exists between the circuit breaker 1066 and the relay 1064, and a current transformer is disposed on the connection portion. Specifically, the connection portion 122 is in the form of a copper busbar, that is, the connection portion 122 includes an input copper busbar 1076, which serves as a conductor for power transmission. The two ends of the input copper busbar 1076 are respectively connected to the output terminal of the circuit breaker 1066 and the input terminal of the relay 1064. By utilizing the conductivity of the copper busbar's own structure, energy loss during power transmission can be reduced, and a stable electrical connection can be provided, enhancing the overall reliability of the system.

[0063] In addition, by passing the input copper busbar 1076 through the current transformer 1067, the current transformer 1067 can detect relevant electrical parameters based on the transformer principle, mainly detecting the magnitude of the current flowing between the circuit breaker and the relay.

[0064] In one embodiment, alternatively, such as Figure 3 and Figure 4 As shown, the base plate 1062 is made of metal. The strength of metal can ensure the stability and durability of the entire module. The input copper busbar 1076, relay 1064 and current transformer 1067 are pre-assembled to form a modular first module 120, which facilitates subsequent assembly with other parts. In particular, the first module 120 is suspended on the base plate 1062 by insulating pillars 116. Under the action of the insulating pillars 116, the first module 120 can be isolated from the base plate 1062, thereby preventing short circuits or leakage caused by current passing through the metal base plate and improving the safety of the system.

[0065] In one embodiment, optionally, both the first and second conductive components that realize the electrical connection between the generator and the main circuit 104 are made of copper busbars, which have low resistance, can efficiently transmit current, and reduce energy loss. Furthermore, the copper busbars provide a reliable connection for power transmission, ensuring the normal operation of the main circuit 104. It can be understood that the first conductive component is a sub-copper busbar 1074, and the second conductive component is an output copper busbar 1078. The sub-copper busbar 1074, as part of the main circuit 104, is used to transmit power, and the output copper busbar 1078 is used to connect the output terminal of the relay 1064 and the sub-copper busbar 1074 of the main circuit 104, thereby realizing the electrical connection between the generator 106 and the main circuit 104, and smoothly transmitting the power generated by the generator 106 to the main circuit 104.

[0066] Of course, since one end of the output copper busbar 1078 is electrically connected to the output terminal of the relay 1064 and the other end is electrically connected to the sub-copper busbar 1074, this design allows the generator device 106 to be easily connected and disconnected from the main circuit 104, improving the system's flexibility and maintainability.

[0067] When the sub-copper busbar 1074 of the first conductive element and the output copper busbar 1078 of the second conductive element are connected, the power generated by the generator 106 can be smoothly transmitted to the main circuit 104 to provide power support for the intelligent distribution box 100 and ensure its normal operation.

[0068] In one embodiment, optionally, the circuit breaker 1066 is located on the side of the first module away from the base plate, with its output terminal positioned close to the output copper busbar 1078, reducing the power transmission path and improving transmission efficiency. Based on this, by providing a connecting copper busbar 1075, the output terminal of the circuit breaker 1066 can be connected to the input copper busbar 1076. Specifically, one end of the connecting copper busbar 1075 is connected to the output terminal of the circuit breaker 1066, and the other end is connected to the input copper busbar 1076.

[0069] For the first module, the output terminal of the circuit breaker 1066 and the input copper busbar 1076 are at opposite ends. By setting up the connecting copper busbar 1075, the two are connected together, ensuring power transmission and making the power transmission path of the entire generator unit 106 more direct and efficient, thus improving the power transmission efficiency and reliability of the system. At the same time, the modular design also simplifies the system installation and maintenance process.

[0070] In one embodiment, an inlet 118 may be provided on the periphery of the enclosure 101 to provide a channel for the oil-electric input cable to enter the enclosure 101, thereby reducing the impact of the external environment on the cable.

[0071] It is understandable that some of the oil and electricity input cables pass through input port 118 and are directly connected to the input terminal of circuit breaker 1066, which simplifies the connection process and improves the convenience of installation and maintenance.

[0072] Copper busbars are metal strips made of conductive materials, usually copper, which has excellent electrical conductivity. By using copper busbars for connections, their good conductivity and heat dissipation properties can help reduce temperature under high loads, prevent overheating, and improve system safety and reliability.

[0073] The system also includes a generator cover 108 that is detachably connected to the housing 101, which facilitates the quick installation or removal of the generator unit 106 when needed, thereby improving the system's flexibility and ease of maintenance.

[0074] When the oiler is not in use, the oiler cover can effectively prevent dust, moisture and other external impurities from entering the oiler housing 1012, protecting the internal components.

[0075] In one embodiment, optionally, the mains power input module is installed inside the enclosure 101. The mains power input module is connected to the main circuit 104, transmitting the mains power input to the main circuit 104 and then distributing it to the load. Simultaneously, it is connected to the mains power input cable to enable mains power access. It can be understood that in this solution, the mains power input module inside the intelligent distribution box 100 can be considered a standard option for the entire intelligent distribution box 100, and a generator can be optionally added on top of it.

[0076] Furthermore, the mains power input module is connected to the control board 102 via signal, and the control board 102 is used to monitor or control the mains power input module.

[0077] The control board 102 can monitor and control the mains input module, such as monitoring parameters like voltage, current, and frequency of the mains power, and controlling the switching state of the mains input module. It can perform corresponding operations according to the mains power conditions. For example, when the mains power is normal, it controls the mains input module to conduct to supply power to the load; when the mains power is abnormal, it cuts off the mains input in time to avoid damage to the load.

[0078] The control board 102 enables automatic switching and control between mains power and generator power supply modes, improving the reliability and flexibility of power supply. In the event of a mains power failure, the generator can be started quickly to ensure continuous power supply to the load; after the mains power is restored, it can automatically switch back to mains power supply, realizing intelligent power management.

[0079] like Figure 4As shown, a first connecting hole 1070 and a second connecting hole 1072 are respectively provided at the relative positions of the base plate 1062 and the distribution box 100, for example, on the box body 101. The size and shape of the first connecting hole 1070 are designed according to the connection requirements and the specifications of the fasteners. The second connecting hole 1072 is provided on the box body 101, and its shape and size match those of the first connecting hole 1070 to ensure that the fasteners can pass through smoothly and achieve connection.

[0080] The number of the first connecting hole 1070 and the second connecting hole 1072 can be reasonably distributed on the base plate 1062 according to the size and stress conditions of the base plate 1062 to ensure the stability of the connection.

[0081] Through the first connecting hole 1070 and the second connecting hole 1072, bolts, screws, and other fasteners can be used to connect the hydraulic base plate 1062 to the second plate, making the connection between the hydraulic base plate 1062 and the second plate detachable. This facilitates the installation and disassembly of the hydraulic unit 106, and makes maintenance and replacement easier.

[0082] like Figure 5 and Figure 6 As shown, this application provides an embodiment of a power distribution box 100, including: a box body 101, in which a control board 102 and a main circuit 104 are provided; a generator housing 1012, disposed in the box body 101, the generator housing 1012 being used to accommodate a generator device 106 as described above when the intelligent power distribution box 100 expands its generator power generation function; wherein, the control board 102 is used to monitor or control the generator device 106 after the main circuit 104 and the relay are electrically connected and the signal board is communicatively connected to the control board 102.

[0083] Before leaving the factory, an expansion interface for generator input and a reserved generator housing cavity 1012 can be reserved. If a user needs to increase generator input during the use of the distribution box 100, they can purchase a generator device 106 compatible with the distribution box 100. By placing the generator device 106 into the reserved generator housing cavity 1012 and connecting the relevant interfaces of the generator device 106 to the reserved generator input expansion interface, the function of expanding generator input in the distribution box 100 can be quickly achieved. The distribution box 100 provided by this utility model utilizes the modular design of the generator device 106, allowing for quick and convenient installation of the generator device 106 after the distribution box 100 is installed, while simultaneously meeting the needs of different users for generator power generation.

[0084] The enclosure 101 serves as the external structure of the distribution box 100. By providing a generator housing 1012 inside the enclosure 101, the generator device 106 can be accommodated when the power generation function of the distribution box 100 is expanded, i.e. when the generator power generation function is expanded. At the same time, the enclosure 101 also provides a certain degree of protection for the internal structure. Especially when the distribution box 100 is placed outdoors, the enclosure 101 can effectively prevent the external environment from affecting the internal electrical components, ensuring that the equipment works normally under various conditions.

[0085] Furthermore, by installing the control board 102 inside the enclosure 101, it is easy to connect and wire with other components, while also being protected by the enclosure 101. The control board 102 is connected to the generator unit 106 for signal transmission, enabling the control board 102 to control the generator unit 106. This ensures that the control board 102 can accurately obtain the status information of the generator unit 106 and issue control commands as needed to realize the functions of starting, stopping, and speed regulation of the generator.

[0086] A main circuit 104 is installed inside the housing 101. By realizing the electrical connection between the generator 106 and the main circuit 104, the electrical energy generated by the generator can be input into the distribution box 100.

[0087] The control board 102 is used to control the generator 106 after it is connected to the power distribution box 100 by detecting the connection status and confirming that the connection is normal, so that it can start, run and stop as needed.

[0088] like Figure 6 As shown, an inlet 118 is provided on the periphery of the enclosure 101 to provide a channel for the oil and electricity input cable to enter the enclosure 101 and reduce the impact of the external environment on the cable.

[0089] It is understandable that some of the oil and electricity input cables pass through input port 118 and are directly connected to the input terminal of the circuit breaker, which simplifies the connection process and improves the convenience of installation and maintenance.

[0090] In one specific embodiment, when installing the generator unit, first remove the fixing screws and grounding copper busbar connecting screws on the generator cover plate inside the housing to disassemble the generator cover plate and assemble the generator unit, which includes a power connection copper busbar, a current transformer (CT), a CT metering module, a relay, an insulating column, and a support frame, etc. After installing the module into the housing, the signal line needs to be inserted into the signal interface to complete the communication access. Fix the first connection hole to the second connection hole of the housing, connect the connecting copper busbar to the sub-copper busbar to complete the power access, and the module assembly can be realized. Finally, lock the cover plate back into the housing and reconnect the fixing screws and grounding copper busbar connecting screws on the generator cover plate.

[0091] According to the generator device and distribution box provided by this utility model, the generator device is an optional accessory of the distribution box, which can flexibly meet the functional expansion needs of the generator input.
