[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Reference Figures 1-2 The present invention provides an embodiment of an energy storage distribution cabinet, comprising a cabinet body 1, a UPS power supply 4 inside the cabinet body 1, a battery control box at the output end of the UPS power supply 4, a low-voltage circuit breaker group 5 at the top of the UPS power supply 4, the two ends of the low-voltage circuit breaker group 5 being disposed on the inner wall of the cabinet body 1, a protective shell at the top of the low-voltage circuit breaker group 5, an EMS control board 6 inside the protective shell, and an intelligent monitoring and early warning system inside the EMS control board 6.

[0022] Specifically, UPS power supply 4 provides uninterrupted power, with its output connected to the battery control box. When an external power source fails or voltage fluctuates, it can quickly switch to continuously power the battery control box and EMS control board 6, ensuring system operation is unaffected by external power interference. The low-voltage circuit breaker group 5 closely monitors the AC220V circuit. In the event of overload, short circuit, or other abnormalities, it can instantly disconnect the faulty circuit, preventing the fault from spreading and ensuring the electrical safety of the entire power distribution system. The intelligent monitoring and early warning system integrated into the EMS control board 6 connects to various sensors distributed at key heat-generating locations in the distribution cabinet, including the battery pack and low-voltage circuit breaker group 5. Among these, the temperature sensor monitors the ambient temperature in real time, converting the temperature signal into an electrical signal and transmitting it to the EMS control board 6. The control board has a pre-set high-temperature threshold; when the received temperature signal exceeds this threshold, the early warning program is immediately activated. Simultaneously, the EMS control board 6 can also collect battery current, voltage, and other parameters in real time and upload this data to the cloud platform via the switch 7, enabling remote monitoring and data analysis, and precise control of the battery charging and discharging process based on preset strategies.

[0023] The intelligent monitoring and early warning system not only enables real-time and accurate monitoring and intelligent control of battery status, optimizing the operating efficiency of the energy storage system and extending battery lifespan, but also allows maintenance personnel to promptly grasp the temperature conditions inside the distribution cabinet through a high-temperature early warning function. This solves the problem of not being able to issue early warnings when temperatures are too high.

[0024] The cabinet 1 has a base at the bottom and a cabinet door 3 connected to it by a hinge. The cabinet door 3 has a placement plate 2 on the inner bottom wall and a switch lock on the outer wall. The cabinet 1 has a fixing hole at the bottom and a forklift transport port on the base. The cabinet 1 has a lifting hole at the top. The placement plate 2 has a grounding point on one side and a warning sign on the side wall of the cabinet door 3.

[0025] Specifically, cabinet 1 has fixing holes at the bottom, which are fastened to the mounting surface by bolts and other connectors. Friction and the mechanical tightening force of the bolts stabilize cabinet 1. The forklift transport port on the base and the lifting hole on the top of cabinet 1 are respectively adapted to forklift forks and lifting equipment hooks. During transportation, the forklift forks insert into the forklift transport port, using the forklift's power to move cabinet 1 horizontally; the lifting hook of the lifting equipment hooks into the lifting hole, using a lifting device to lift cabinet 1 vertically. Cabinet door 3 is rotatably connected to cabinet 1 via hinges, with the hinge's pivot point as the center for opening and closing. The inner bottom wall of cabinet door 3 has a placement plate 2 for storing operation manuals, maintenance records, and other documents, allowing operators easy access. A grounding design on one side of placement plate 2 connects placement plate 2 to the grounding system of cabinet 1 via a wire, ensuring placement plate 2 is at ground potential.

[0026] The mounting holes ensure that cabinet 1 remains stable in its designated position after installation, preventing displacement or tipping due to external impacts, vibrations, or other factors. The forklift loading port and lifting holes enable efficient and safe transport of cabinet 1 during handling. The hinged cabinet door 3 allows operators to easily open and close cabinet 1, providing convenient access to internal electrical components and facilitating routine maintenance and repair. This solves the problems of inconvenient installation and opening of traditional distribution cabinets.

[0027] A switch 7 is installed on one side of the EMS control board 6, and a 24V DC-DC 8 is installed on the other side of the switch 7. The switch 7 and the 24V DC-DC 8 are located inside the protective casing.

[0028] Specifically, the EMS control board 6, switch 7, and 24V DC-DC converter 8 are all housed within a protective enclosure. During operation, the EMS control board 6 collects a large amount of data, including battery current, voltage, and temperature. Switch 7 on one side uses packet switching technology, based on the MAC address in the data packets, to enable high-speed data transmission between the EMS control board 6 and other devices, such as remote monitoring terminals and other power distribution cabinet components. The 24V DC-DC converter 8 uses power conversion technology to convert the higher input voltage into a stable 24V DC voltage, providing precise low-voltage power to devices within the power distribution cabinet that require 24V.

[0029] Switch 7 ensures the real-time and accurate data interaction between the EMS control board 6 and external systems, enabling remote monitoring and intelligent management. Maintenance personnel can monitor the power distribution cabinet's operating status in real time via a remote terminal. This resolves issues related to poor data transmission and power supply compatibility with the equipment.

[0030] The two ends of the protective shell are set on the inner wall of the cabinet 1, and the top of the protective shell is equipped with an emergency brake button 9. The top of the emergency brake button 9 is equipped with a control display screen 10.

[0031] Specifically, the emergency stop button 9 is located on the top of the protective casing. In the event of a serious malfunction or emergency, the operator presses the button, which immediately triggers a control signal. This signal is transmitted through the internal circuit to the main control circuit of the distribution cabinet, quickly cutting off the power supply to the main circuit and some critical control circuits, causing the equipment in the distribution cabinet to stop operating immediately. The control display screen 10 is connected to the EMS control board 6, receiving the data transmitted from it and displaying information such as battery cluster status and system operating parameters in an intuitive graphical and digital interface.

[0032] The emergency stop button 9 provides a rapid safety mechanism for the distribution cabinet in emergencies, instantly stopping equipment operation to prevent further escalation of the accident and protect equipment and personnel safety. This solves the problem of the lack of a rapid and effective braking method for distribution cabinets in emergency situations.

[0033] A fault light 11 is provided at the top of the control display screen 10, an alarm light 13 is provided on one side of the fault light 11, a running light 12 is provided on one side of the alarm light 13, and three power indicator lights 14 are provided at the top of the fault light 11, alarm light 13 and running light 12.

[0034] Specifically, fault indicator 11, alarm indicator 13, running indicator 12, and three-phase power indicator 14 are connected to the corresponding monitoring circuits within the distribution cabinet. When a serious equipment fault occurs, the fault monitoring circuit triggers fault indicator 11 to illuminate red; when the equipment malfunctions but has not yet reached a fault level, the alarm circuit causes alarm indicator 13 to illuminate yellow; when the equipment is operating normally, the running monitoring circuit causes running indicator 12 to illuminate green. Three-phase power indicator 14 monitors the connection and operating status of the three-phase power supply in real time, illuminating green when the power supply is normal.

[0035] Indicator lights, with their clear and conspicuous color changes, allow operators to quickly determine the equipment's operating status from a distance: whether it is operating normally, experiencing an alarm, or malfunctioning, and whether the three-phase power supply is properly connected. This solves the problem of quickly determining the operating status of the distribution cabinet.

[0036] Working Principle: The UPS power supply 4 continuously supplies power to the battery control box and EMS control board 6, and quickly switches to maintain system stability in case of external power failure. The low-voltage circuit breaker group 5 closely monitors the AC220V circuit; in case of overload, short circuit, or other faults, it immediately cuts off the circuit to prevent the fault from escalating. The EMS control board 6 integrates an intelligent monitoring and early warning system, connecting to various sensors to collect data. Temperature sensors monitor the temperature of key components, triggering a high-temperature warning when the temperature exceeds a preset threshold. Simultaneously, the EMS control board 6 collects battery parameters, which are uploaded to the cloud platform via the switch 7 for remote monitoring and data analysis, and to regulate battery charging and discharging. The cabinet 1 is well-designed, with bottom fixing holes and bolts for securing it, and forklift transport and lifting holes for easy handling. The cabinet door 3 opens and closes via hinges, and a lock ensures safety. The storage board 2 stores documents and is grounded on one side. The emergency stop button 9 cuts off the circuit in case of emergency. The control display screen 10 shows the equipment status, and indicator lights such as fault lights 11 and alarm lights 13 visually present the operating status, ensuring operators can promptly understand and handle problems.

[0037] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
