[0002] With the development of energy conservation, emission reduction, and a low-carbon economy, wind power and photovoltaic power generation devices have been widely used in engineering practice due to their clean and renewable characteristics. However, these two power generation systems suffer from unstable power generation, being greatly affected by weather and natural conditions. To address this issue, new energy storage devices are combined with renewable energy power generation equipment to construct microgrids or isolated grid systems, which can meet local electricity demand in remote areas or places with unstable power supply.

[0003] In power systems, since the loads are primarily AC (alternating current) while photovoltaic (PV) power generation and energy storage batteries output DC (direct current), DC-to-AC conversion is necessary. Simultaneously, to ensure the stable operation of critical loads, diesel generators are typically configured as backup power. To simultaneously connect multiple input sources such as PV, energy storage batteries, diesel generators, and mains power, a common solution is to use multiple devices operating in conjunction. However, this approach requires various devices with different functions to connect and convert multiple input sources; the lack of high integration between these devices leads to system complexity and a large footprint; and the transportation and installation of multiple devices requires more time and resources, increasing the difficulty and cost of project implementation. These issues limit the system's flexibility and reliability, especially in remote areas or space-constrained scenarios.

[0004] Therefore, a hybrid converter that is compact, highly integrated, and capable of simultaneously connecting multiple photovoltaic, energy storage battery, mains power, and diesel generator to provide reliable power input for equipment loads is a problem that urgently needs to be solved by those skilled in the art.

The photovoltaic input module 2-4 connects to the photovoltaic DC input and supplies power to the photovoltaic DC-DC module 1-4. The low-voltage control module 2-5 includes various controllers, connecting the various functional modules and power modules within the equipment, thereby achieving overall equipment control.

[0048] The diesel generator and mains power inlet module 2-1 and the load and battery cluster inlet module 2-2 are located behind a power cable distribution chamber 2-3, which can be connected to the power compartment 1 above the equipment via copper busbars and cables. Each functional module is clearly partitioned. Furthermore, each functional module can be independently disassembled, assembled, and replaced, such as... Figure 6 and Figure 7 As shown, the diesel generator and mains power inlet module 2-1, the load and battery cluster inlet module 2-2, the power cable distribution cavity 2-3, and the photovoltaic inlet module 2-4 have the same width and height dimensions, enabling modular installation and improving the convenience of equipment production.

[0049] The hybrid converter cabinet, through a modular design, achieves efficient integration and collaborative operation of various power modules and functional modules by cooperating with the power modules in power compartment 1 and the functional modules in distribution compartment 2. This allows the converter to connect to multiple photovoltaic systems, multiple energy storage battery clusters, diesel generators, and grid power, enabling multi-directional energy flow and active control of power flow. The complementary functions of each module support multi-energy complementarity, intelligent scheduling, and flexible configuration, meeting the power demands of different scenarios, and is particularly suitable for microgrids, energy storage systems, and distributed energy applications.

[0050] The hybrid converter cabinet provided by this utility model has an overall layered structure, divided into a power compartment 1 and a power distribution compartment 2. The power compartment 1 can accommodate power modules of various sizes, while the power distribution compartment 2 adopts a multi-layered design in the cabinet's depth direction. Each functional unit employs a modular design, allowing for independent disassembly, assembly, and replacement of each module. This modular installation improves the convenience of equipment production, simplifies installation and maintenance, and enables functional topology flexibility, thus adapting to different application scenarios and user needs. Through modular design and efficient integration, the equipment size is reduced, power density is increased, and modules can be flexibly configured according to different requirements, adapting to various application scenarios.

[0051] Based on the above specific embodiments, the power compartment 1 is provided with multiple side cable trays 1-6 and a top cable tray 1-7, wherein the top cable tray 1-7 and the side cable trays 1-6 are interconnected, and the inner sides of the top cable tray 1-7 and the side cable trays 1-6 are provided with through holes that connect to the inside of the cable trays. The cables of each power module are routed through the top cable tray 1-7 and the side cable trays 1-6 to the lower power distribution compartment 2. The power distribution compartment 2 is provided with multiple cable trays 2-7 installed in different directions, and the cable trays 2-7 are provided with multiple through holes. The cable trays 2-7 include interconnected horizontal cable trays, vertical cable trays and longitudinal cable trays.

[0052] In one specific embodiment, the hybrid converter cabinet achieves efficient cable management between the power compartment 1 and the power distribution compartment 2 through a cable tray system.

[0053] Side cable trays 1-6 are located on the sides of the power compartment 1 to accommodate and guide the cables of the power modules. Top cable trays 1-7 are located on the top of the power compartment 1 and communicate with the side cable trays 1-6. Both the top cable tray 1-7 and the side cable trays 1-6 have through holes on their inner sides, facilitating cable routing from the power modules into the cable trays, simplifying cable insertion and securing, and improving system safety. The power module cables extend downwards through the top cable trays 1-7 and the side cable trays 1-6 to the power distribution compartment 2, resulting in clear cable routing, facilitating installation and maintenance, reducing cable clutter and the risk of short circuits, and maximizing space utilization.

[0054] The power distribution compartment 2 contains multiple cable trays 2-7 arranged in different directions, including horizontal, vertical, and longitudinal cable trays. These cable trays are interconnected and can connect to the power cable distribution cavity 2-3, the photovoltaic input module 2-4, and the low-voltage control module 2-5, forming a three-dimensional cable management system. The cable trays 2-7 have multiple through holes, facilitating the flexible extension of cables from the power compartment 1 down to the various functional modules within the power distribution compartment 2, reducing cable clutter and the risk of short circuits. The through hole design ensures flexible cable arrangement in different directions while preventing mutual interference, excessive bending, and damage between cables.

[0055] In the above structure, the cables of the power module and the functional module are managed through a unified cable tray system, which supports modular installation and expansion, improves the system's flexibility and scalability, facilitates the adjustment of module configuration according to needs, and facilitates quick maintenance and replacement of modules. The design of the cable tray system makes the cable routing clear, facilitates management and maintenance, and reduces maintenance time and costs.

[0056] Based on the above specific embodiments, the housing is provided with multiple connection holes, and the insert frame 1-5, the side cable groove 1-6 and the top cable groove 1-7 are connected to the connection holes. The insert frame 1-5, the side cable groove 1-6 and the top cable groove 1-7 are detachably connected to the connection holes.

[0057] In one specific embodiment, the hybrid converter cabinet is designed with a modular and detachable connection method, which allows for flexible installation and removal of components such as the insertion frames 1-5 and cable trays through the connection holes on the housing.

[0058] Specifically, the housing has multiple connection holes. The insertion frame 1-5, side cable tray 1-6, and top cable tray 1-7 can be fixed to the connection holes using bolts, clips, or other connectors. The insertion frame 1-5, side cable tray 1-6, and top cable tray 1-7 are all detachably connected to the housing via these connection holes. When a particular insertion frame 1-5 or cable tray needs to be replaced, only the connector needs to be removed, eliminating the need for extensive disassembly of the entire cabinet, thus reducing maintenance time and costs. Furthermore, the number of insertion frames 1-5 can be increased or decreased according to the system's scale, and the cable tray layout can be adjusted.

[0059] The converter adopts an assembly structure. By replacing the plug frame 1-5, the side cable tray 1-6, and the top cable tray 1-7, the power compartment 1 can be quickly modified to adapt to power modules of different sizes, different wiring harness specifications, and different wiring methods. The plug frame 1-5, cable trays, and other components can be flexibly configured according to actual needs, and have better compatibility and expandability.

[0060] Preferably, the mounting holes of the connecting holes and the insert frame 1-5, the side cable groove 1-6, and the top cable groove 1-7 have the same diameter. By using standardized connecting holes, errors during the installation process are reduced, and the overall reliability of the system is improved.

[0061] Based on the above specific embodiments, the side plate of the housing is provided with a vertically arranged sliding groove, and the side walls of the insertion frame 1-5, the side cable groove 1-6 and the top cable groove 1-7 are connected with threaded rods. The threaded rods are connected in the sliding grooves and the ends are fastened by nuts. The threaded rods move and cooperate with the sliding grooves.

[0062] In one specific embodiment, the hybrid converter cabinet adopts a combination of slide rails and threaded rods, which enables flexible installation and adjustment of the insertion frame 1-5, the side cable tray 1-6 and the top cable tray 1-7.

[0063] The housing side panel features vertically oriented grooves for mounting and securing the insert frame 1-5, side cable tray 1-6, and top cable tray 1-7. Threaded rods are connected to the side walls of the insert frame 1-5, side cable tray 1-6, and top cable tray 1-7. The threaded rods are inserted into the grooves and tightened with nuts to ensure stable installation. The movable engagement of the threaded rods and grooves allows for vertical adjustment of the components. For example, the position of the insert frame 1-5 can be adjusted according to the height of the power module, or the layout of the cable trays can be adjusted according to the cable routing. This flexible adjustment accommodates insert frames 1-5 and cable trays of different sizes and heights, enhancing the system's versatility and compatibility while ensuring secure installation. When replacing or upgrading components, simply loosen the nuts and adjust the threaded rod position for a quick and easy operation. The engagement of the threaded rods and grooves ensures the stability of the components during operation, reducing loosening caused by vibration or external forces.

[0064] Based on the above specific embodiments, the insert frame 1-5 includes a pair of horizontally opposite L-shaped plates, the vertical plate of which is connected to the housing, and each power module is supported and connected to the horizontal plate.

[0065] In one specific embodiment, the insertion frame 1-5 consists of a pair of horizontally opposite L-shaped plates, each L-shaped plate including a vertical plate and a horizontal plate. The vertical plate is connected to the housing, serving a fixing and supporting function. The horizontal plate is used to support and connect the power module, ensuring stable installation of the module. The power module is supported and connected via the horizontal plate, facilitating quick installation and disassembly. The L-shaped plates allow the insertion frame 1-5 to be flexibly installed inside the housing, with its position adjusted by the movement of the vertical plate within the slide groove, accommodating power modules of different heights and sizes.

[0066] The vertical plate can be connected to the sliding groove on the side plate of the housing via a threaded rod and secured with a nut. It can be quickly installed and disassembled according to actual needs, allowing the position of the insert frames 1-5 to be adjusted in the vertical direction while ensuring the stability of the installation.

[0067] Based on the above specific embodiments, the horizontal plate of the insert frame 1-5 is provided with a slide rail, the bottom surface of each power module is provided with a slide bar, the slide bar and the slide rail are slidably connected, the slide rail and the slide bar are along the depth direction of the shell, the front end of the slide rail is provided with an anti-detachment protrusion, the rear end of the slide bar is provided with an anti-detachment groove, and the anti-detachment protrusion is engaged with the anti-detachment groove.

[0068] In one specific embodiment, a slide rail is provided on the horizontal plate of the insertion frame 1-5, and a slide bar is provided on the bottom surface of the power module. The slide bar and the slide rail are slidably connected along the depth direction of the housing, reducing friction and wear during the sliding process, and allowing the power module to move smoothly along the insertion frame 1-5. The design of the slide rail and slide bar supports modular installation, making it easy to flexibly adjust the layout of the power module according to needs. The front end of the slide rail is provided with an anti-detachment protrusion, and the rear end of the slide bar is provided with an anti-detachment groove. The anti-detachment protrusion engages with the anti-detachment groove. The anti-detachment structure effectively prevents the module from falling off due to vibration or external force during operation, effectively preventing the module from accidentally falling off during operation, and ensuring the stability of the module through mechanical limiting.

[0069] The design of the insert frame 1-5 adopts the combination of slide rail and slide bar, and enhances the stability and safety of the module through the structure of anti-detachment protrusion and anti-detachment groove.

[0070] Based on the above specific embodiments, an installation positioning unit is also included, which includes:

[0071] A contact piece located at the rear end of the slide rail;

[0072] Contacts located at the rear end of each power module;

[0073] An installation module that connects to the contact plate and is used to send a signal indicating that each power module is installed when it comes into contact with the contact plate.

[0074] In practical applications, the contact piece is mounted at the rear end of the slide rail as a detection element. The contact point is mounted at the rear end of each power module and mates with the contact piece. When the power module slides along the slide rail and is installed in place, the contact point makes contact with the contact piece. The installation module is connected to the contact piece and is used to detect the contact state between the contact point and the contact piece. Once the contact point makes contact with the contact piece, the installation module sends a signal indicating that the power module has been correctly installed.

[0075] The installation positioning unit ensures that each power module is correctly installed by detecting contact between contacts and contact plates, preventing poor contact or system malfunctions caused by incomplete module installation. The signal emitted by the installation positioning module can be received by the system control unit, enabling real-time monitoring of the module installation status. This facilitates pre-start self-checks to ensure all modules are correctly installed. When the system detects that a module is not properly installed, it can alert maintenance personnel through alarms or prompts, allowing for quick location of the problematic module and reducing maintenance time and costs. The design of the installation positioning unit avoids safety hazards caused by loose or improperly installed modules, improving the overall system stability.

[0076] Based on the above specific embodiments, the power compartment 1 and the power distribution compartment 2 are separated by a load-bearing partition 3. The shell is provided with a front door panel and a rear door panel. The front door panel and the rear door panel area corresponding to the power module are provided with multiple ventilation holes 4. The high-voltage area and the low-voltage area in the power distribution compartment 2 are separated and separated.

[0077] In one specific embodiment, the power compartment 1 and the power distribution compartment 2 are separated by a load-bearing partition 3 to ensure the functional independence and structural stability of the two areas. The load-bearing partition 3 not only serves as a physical separation but also supports the weight of the power modules and power distribution modules, enhancing the overall stability of the cabinet.

[0078] The enclosure has a front door panel and a rear door panel. The power modules and functional modules of the cabinet can be installed on the front or rear side, which not only protects the internal modules but also facilitates maintenance and repair.

[0079] Multiple ventilation holes 4 are provided in the front and rear door panels corresponding to the power module for heat dissipation and ventilation, which helps to reduce the heat generated by the power module during operation and improve the stability and reliability of the system.

[0080] The power distribution compartment 2 separates the high-voltage and low-voltage areas to avoid interference from high-voltage signals to low-voltage signals, thereby improving the system's anti-interference capability and ensuring stable transmission of control signals.

[0081] In terms of overall layout, there are clear partitions between each functional module. The high-voltage area and low-voltage area inside the cabinet are arranged separately, and the human-machine interface of the operation and debugging unit is isolated from the power distribution area, thereby ensuring the safety of operation during inspection and maintenance.

[0082] Based on the above specific embodiments, the high-voltage function module is equipped with a revolving door 2-6. The revolving door 2-6 is installed on the electric door body 2-6-1 and the cover plate 2-6-2 which is rotatably connected to the electric door body 2-6-1 on the high-voltage function module. The revolving door 2-6 is provided with a safety lock so that the high-voltage function module can be powered on after the electric door body 2-6-1 and the cover plate 2-6-2 are locked.

A cover plate 2-6-2 is rotatably connected to the ESO door body 2-6-1, used to cover and protect the internal electrical components. The design of the revolving door 2-6 allows for the installation of frequently accessed devices such as miniature circuit breakers, equipment external interfaces, and sockets. This design not only improves the space utilization of the electrical distribution compartment 2, making the equipment more compact, but also reduces the opportunity for maintenance personnel to access high-voltage areas within the equipment, thereby enhancing the safety and convenience of maintenance operations.

[0084] The revolving door 2-6, through the cooperation of the door body and cover plate 2-6-2, protects and operates the high-voltage electrical module. The revolving door 2-6 is equipped with a safety lock; the high-voltage electrical module can only be energized after the door body 2-6-1 and cover plate 2-6-2 are fully locked. This design ensures that during maintenance or operation, the equipment is only energized when the revolving door 2-6 is fully closed and locked. The mechanical locking mechanism ensures the stability of the equipment during operation and effectively prevents electrical short circuits or electric shock accidents caused by an open door. This significantly improves system safety and is particularly suitable for high-voltage electrical equipment requiring frequent operation and maintenance.

[0085] The rotating connection between the cover plate 2-6-2 and the electric door body 2-6-1 makes the operation more flexible. The rotating door 2-6 can be opened and closed quickly, which facilitates the maintenance and repair of the high-voltage function module.

[0086] Based on the above specific embodiments, the bottom of the functional module is provided with two sliding balls, each installation position of the power distribution compartment 2 is provided with two longitudinal tracks, and multiple rows of transverse tracks are provided in the depth direction. The longitudinal tracks and transverse tracks are connected. The functional module slides in along the longitudinal track and switches between the left and right installation positions through the transverse track.

[0087] In one specific embodiment, the functional module has two sliders located on either side of its bottom. The slider design allows the functional module to move in multiple directions along the track, not just in a straight line, but also enabling more flexible steering and positioning. The spherical structure of the sliders reduces friction, making the module's movement smoother. The sliders are typically made of wear-resistant, low-friction materials such as polyoxymethylene or nylon to extend their service life.

[0088] Each mounting position has two longitudinal tracks and multiple rows of transverse tracks along the depth direction. The transverse tracks connect with the longitudinal tracks to form a grid-like track system. The functional module slides into the power distribution compartment 2 via the longitudinal tracks, and a slider moves along the tracks to ensure the module smoothly enters the predetermined position. After entering the power distribution compartment 2, the module switches to different left and right mounting positions via the transverse tracks. The slider allows the module to flexibly adjust its position on the transverse tracks, supporting multi-directional adjustments and enabling switching between left and right areas.

[0089] The longitudinal and transverse tracks are seamlessly connected via mechanical links or an embedded design. Guide devices can be included at the track connections to ensure the smoothness of the slider when switching tracks.

[0090] The combination of longitudinal and transverse tracks allows functional modules to be compactly arranged within power distribution compartment 2, enabling the installation of more modules in a limited space and improving space utilization. Through the interaction of the sliding ball with the longitudinal and transverse tracks, the functional modules within power distribution compartment 2 can be flexibly installed, switched, and assigned to different areas. This design not only improves the system's flexibility and scalability but also facilitates maintenance and operation.

[0091] The hybrid converter cabinet provided by this utility model maximizes the space utilization within the converter through a reasonable functional module layout design. The compact structure can significantly reduce the cabinet's floor area and height, thereby greatly improving its adaptability to transportation scenarios.

[0092] The power compartment 1 can adjust the type and quantity of power modules according to different power supply environments and needs. The distribution compartment 2 can also reorganize the functional modules according to different application scenarios and required functions, so that the converter can cover flexible allocation of photovoltaic, energy storage, diesel generation and grid input in terms of function, realizing the topology of the converter in terms of function and capacity.

[0093] The various embodiments in this specification are described in a progressive manner, with each embodiment focusing on the differences from other embodiments. The same or similar parts between the various embodiments can be referred to each other.
