Description

Technical Field

[0001] The utility model relates to the technical field of power distribution cabinets, in particular to a modular combined high and low voltage power distribution cabinet. Background Art

[0002] In the existing power distribution system, high and low voltage distribution cabinets are an indispensable and important part. However, the traditional distribution cabinet design often has some obvious defects and deficiencies, which greatly restricts the efficiency and safety of the distribution system.

[0003] First, the design of traditional power distribution cabinets often integrates high-voltage distribution modules and low-voltage distribution modules in the same cabinet. Although this design simplifies the structure to a certain extent, it brings great inconvenience to installation and maintenance. Since the high-voltage and low-voltage modules interfere with each other, it not only increases the difficulty of maintenance, but also reduces the stability of the entire system.

[0004] Furthermore, heat dissipation is also an important challenge faced by traditional power distribution cabinets. Due to the limited space inside the cabinet and the large amount of heat generated by the high and low voltage distribution modules, if the heat dissipation system is not designed properly, it is easy to cause the temperature inside the cabinet to be too high, thus affecting the normal operation of components and even causing safety accidents. In view of this, we propose a modular combined high and low voltage power distribution cabinet. Utility Model Content

A front door 4 is hingedly installed on the front side of the first cabinet 1 and the second cabinet 2 through a hinge 43, and a door handle 41 and a door lock 42 are installed on the front door 4. The modular combined high and low voltage power distribution cabinet realizes the separation and combination of the high voltage power distribution module 11 and the low voltage power distribution module 12 through the design of the first cabinet 1 and the second cabinet 2, which is convenient for installation and maintenance. The opening 15 and the baffle 16 that can be slid open are designed to facilitate the connection and maintenance of the lines. The first mounting plate 6 and the second mounting plate 8 are fixedly connected by fixing bolts 7, which enhances the structural stability of the cabinet.

The air outlet 14 provided on the left outer wall of the cabinet, the heat dissipation component 13 installed inside, and the air inlet provided on the front door 4 and the filter 40 installed form an effective heat dissipation system. This design can improve the heat dissipation performance of the power distribution cabinet, prevent equipment from overheating, ensure the normal operation of the internal components of the power distribution cabinet, and extend the service life.

[0027] As a preferred embodiment of the present invention, the heat dissipation assembly 13 includes a mounting frame 130, a fixing plate 131 is fixedly mounted in the mounting frame 130, a driving motor 133 is fixedly connected to the fixing plate 131, and a fan blade 132 is coaxially fixedly mounted on the output shaft of the driving motor 133. The detailed design of the heat dissipation assembly 13, including the mounting frame 130, the fixing plate 131, the driving motor 133 and the fan blade 132, constitutes an active heat dissipation system. The driving motor 133 drives the fan blade 132 to rotate, accelerates the air flow inside the power distribution cabinet, improves the heat dissipation efficiency, and further ensures the stable operation of the power distribution cabinet.

[0028] As a preferred embodiment of the present invention, a protective net 3 is installed in the air outlet 14. This can prevent external dust and debris from entering the power distribution cabinet and causing damage to internal components, and also prevent small animals from entering, thereby improving the safety and reliability of the power distribution cabinet.

[0029] As a preferred embodiment of the present invention, square holes are provided on the first mounting plate 6 and the second mounting plate 8 for connecting the two openings 15. The square holes provided on the first mounting plate 6 and the second mounting plate 8 correspond to the openings 15, which facilitates the passage and connection of the lines, making the connection between the high and low voltage distribution modules more convenient and flexible.

[0030] As a preferred embodiment of the present invention, a support block 5 is welded at each of the four corners of the bottom of the first mounting plate 6, the support block 5 passes through the second mounting plate 8, and a support leg 9 is fixedly connected to each of the four corners of the bottom of the second cabinet 2. The design of the support block 5 and the support leg 9 enhances the stability of the power distribution cabinet, ensures the stability of the power distribution cabinet during installation and use, and prevents tilting or collapse due to external factors.

[0031] As a preferred embodiment of the present invention, two baffles 16 are provided in one opening 15, and a movable groove 18 for the baffle 16 to move is provided on the inner wall of the opening 15. Two baffles 16 are provided in one opening 15, and the baffle 16 can be opened by sliding sideways through the movable groove 18, which further facilitates the connection and maintenance of the line and improves the convenience of operation.

[0032] As a preferred embodiment of the present invention, a connecting block 17 is fixed to one side of the baffle 16 near the middle of the opening 15, and two connecting blocks 17 in the same opening 15 are connected by connecting bolts. The design of the connecting block 17 and the connecting bolts on the baffle 16 enables the two baffles 16 in the same opening 15 to be firmly connected together, thereby enhancing the structural stability of the power distribution cabinet and facilitating the opening and closing operations of the baffle 16.

[0033] When the modular combined high and low voltage power distribution cabinet of the utility model is used, firstly, the modular combined high and low voltage power distribution cabinet realizes the separation and combination of the high voltage power distribution module 11 and the low voltage power distribution module 12 through the design of the first cabinet 1 and the second cabinet 2, and this design is convenient for installation and maintenance. In actual use, the high voltage power distribution module 11 and the low voltage power distribution module 12 can be installed and debugged separately, which improves work efficiency.

[0034] When it is necessary to connect or overhaul the circuit, the baffle 16 can be opened by sliding sideways to facilitate the operation. Two baffles 16 are arranged in each opening 15, and these baffles 16 can be easily opened when needed through the movable slot 18 without disassembling the entire distribution cabinet, thereby greatly simplifying the process of circuit connection and overhaul.

[0035] During the operation of the power distribution cabinet, the heat dissipation system plays a key role. The drive motor 133 in the heat dissipation component 13 drives the fan blades 132 to rotate, accelerating the air flow inside the power distribution cabinet, thereby improving the heat dissipation efficiency. At the same time, the air inlet and filter 40 on the front door 4 allow fresh air to enter the power distribution cabinet, while the air outlet 14 discharges hot air, thereby forming an effective circulation heat dissipation, ensuring the normal operation of the internal components of the power distribution cabinet and extending their service life.
