Description

Technical Field

[0001] This utility model relates to the field of low-voltage distribution cabinet technology, specifically a modular low-voltage distribution cabinet. Background Technology

[0002] A low-voltage switchgear is an electrical device used for centralized control and distribution of low-voltage electrical energy. It mainly consists of a cabinet, switchgear, protective devices, measuring instruments, and busbars. The cabinet is typically made of metal, providing excellent protection against dust, moisture, and foreign objects. Low-voltage switchgear is widely used in power supply and distribution systems in industrial, commercial, and building sectors. It is a crucial piece of equipment for ensuring the stable operation and reliable power supply of the power system, serving as a transmission, distribution, and energy conversion unit. It is generally used as a set of multiple low-voltage switchgear units combined together.

[0003] A search revealed that Chinese Patent Publication No. CN222029509U discloses a low-voltage distribution cabinet, relating to the field of distribution cabinet technology. The low-voltage distribution cabinet includes a cabinet body and a lighting assembly. The cabinet body has a cavity for accommodating components. The lighting assembly includes a lamp source, a lamp clamp, and a deformable rod. The lamp clamp detachably holds the lamp source. One end of the deformable rod is connected to the cavity wall, and the other end is movably connected to the lamp clamp, allowing the lamp clamp to move relative to the deformable rod. The deformable rod can deform and fix the lamp clamp in its current position. The lamp clamp's ability to move relative to the deformable rod allows adjustment of the lamp source's illumination direction. Furthermore, the deformable rod's ability to deform and fix the lamp clamp in its current position allows the lamp source to be moved to a target position by driving the deformable rod to deform. The deformable rod itself has a certain supporting force, which can fix the lamp source in the target position. This facilitates illuminating components during maintenance and improves the work efficiency of maintenance personnel.

[0004] However, this device also has the following drawbacks:

[0005] Existing low-voltage distribution cabinets have a large overall footprint, each cabinet has a single function, and disassembly and reassembly are inconvenient after a single cabinet fails, resulting in a large workload and low maintenance efficiency. This device does not solve this problem. Utility Model Content

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.

[0024] Please see Figures 1-3 This utility model provides a modular low-voltage distribution cabinet, including a main structure. The main structure includes a top cover 1 and a cabinet frame main beam 5. The top of the top cover 1 has several bridge-shaped holes 2. Four sets of lifting rings 4 are fixedly installed around the top cover 1. The bottom of the top cover 1 is fixedly connected to the two ends of two sets of cabinet frame main beams 5 through four sets of cabinet frame vertical beams 3. Cabinet side beams 8 are fixedly installed between the cabinet frame vertical beams 3. Reinforcing triangular plates 14 are installed between the cabinet frame vertical beams 3 and the cabinet side beams 8 by screws. One end of the door stop beam 7 is fixedly connected to the bottom of the partition 13. The top of the partition 13 is fixedly connected to the top cover 1. The other end of the door stop beam 7 is fixedly connected to the cabinet frame vertical beam 3. The top of the door stop beam 6 is fixedly connected to the door stop beam 7. The bottom of the door stop beam 6 is fixedly connected to the cabinet frame main beam 5.

[0025] The top cover 1 is fixedly connected to the two ends of the four sets of cabinet frame vertical beams 3 and the two sets of cabinet frame horizontal beams 5, forming a stable cuboid frame structure. This provides solid support for the distribution cabinet, enabling it to withstand certain external forces and equipment weight without easily deforming. Reinforcing triangular plates 14 are installed between the cabinet frame vertical beams 3 and the cabinet side horizontal beams 8. Utilizing the stability of triangles, the overall structural strength of the cabinet is further enhanced, making the distribution cabinet more robust and reliable during transportation, installation, and use. This reduces the risk of structural damage caused by factors such as vibration and collision. The bridge-shaped holes 2 can accelerate the heat dissipation of electronic components inside the cabinet, facilitating the lifting and handling of the distribution cabinet using hoisting equipment. The lifting rings 4 ensure the balance and stability of the distribution cabinet during lifting, preventing tilting or damage to the cabinet due to unreasonable lifting points, and improving the convenience of transportation and installation.

[0026] This utility model also includes a door stop beam 7. Door stop beams 7 are fixedly installed on both sides of the main structure. The main structure is divided into an upper part and a lower part by the door stop beams 7. A partition 13 is provided in the middle of the upper part. One side of the partition 13 is set as a circuit breaker compartment 15, and the other side of the partition 13 is set as a capacitor compartment 17. The lower part is divided into two sets of outgoing compartments 16 by door stop vertical beams 6. Cabinet side vertical beams 9 are provided on both sides of the outgoing compartments 16. The top and bottom of the cabinet side vertical beams 9 are fixedly connected to the cabinet side cross beams 8. Mounting beams are provided in the circuit breaker compartment 15, capacitor compartment 17 and outgoing compartment 16. The mounting beams are fixedly connected to the main structure.

[0027] The main structure is divided into upper and lower parts by the door stop beam 7. The upper part is divided into a circuit breaker compartment 15 and a capacitor compartment 17 by a partition 13 in the middle. The lower part is divided into two sets of outgoing cable compartments 16 by the door stop beam 6. This regional design allows electrical equipment with different functions to be installed in categories, resulting in high space utilization, small footprint, and convenient operation, maintenance and management. It also reduces mutual interference between different equipment and improves the operational safety and reliability of the distribution cabinet. The circuit breaker compartment 15, capacitor compartment 17 and outgoing cable compartment 16 are equipped with mounting beams to facilitate the installation and fixing of various electrical equipment. This makes full use of the cabinet space, allowing the distribution cabinet to accommodate more equipment in a limited space, thus improving space utilization.

[0028] This utility model also includes a concealed hinge installation door 10 and a maintenance rear door 11, which are respectively installed on both sides of the circuit breaker compartment 15, the capacitor compartment 17 and the outgoing line compartment 16, and are equipped with door locks 12.

[0029] Concealed hinged mounting doors 10 and maintenance rear doors 11 are installed on both sides of each compartment, and door locks 12 are installed. On the one hand, this effectively prevents unauthorized personnel from opening the cabinet doors and accessing the internal electrical equipment, ensuring personnel safety. On the other hand, the concealed hinge design makes the cabinet doors look cleaner and more aesthetically pleasing, while also enhancing the cabinet doors' sealing performance, reducing the possibility of dust and moisture entering the cabinet, and helping to protect the internal electrical equipment. Separating equipment with different functions into different compartments and protecting them with door locks 12 effectively prevents operators from accidentally touching other equipment during operation, reducing the risk of safety accidents caused by misoperation. The installation of maintenance rear doors 11 provides convenience for equipment maintenance. Maintenance personnel can perform equipment maintenance and repair in each compartment through maintenance rear doors 11 without disassembling other parts, reducing maintenance workload and time. At the same time, each compartment is relatively independent, and the maintenance of one piece of equipment will not affect the normal operation of other compartments, improving the maintainability and operational continuity of the distribution cabinet.

[0030] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
