Description

Technical Field

[0001] This utility model relates to the field of electrical control cabinet technology, and in particular to a double-layer electrical control cabinet. Background Technology

[0002] In the field of electrical control cabinets, traditional single-layer electrical boxes have many shortcomings due to their simple structure. Firstly, they have low space utilization; the mixing of high-voltage and low-voltage equipment not only easily causes electromagnetic interference but also leads to insufficient heat dissipation. Secondly, maintenance is inconvenient; components are centrally installed, requiring a complete power outage during maintenance, severely impacting production efficiency. Furthermore, existing electrical control cabinets mostly use single-layer sheet metal structures, which lack material strength and corrosion resistance, making them prone to deformation or rust over long-term use. Therefore, we propose a double-layer electrical cabinet structure. Utility Model Content

[0018] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings and examples. The following examples are only used to more clearly illustrate the technical solution of this utility model and should not be construed as limiting the scope of protection of this utility model.

[0019] like Figures 1-4 As shown, this utility model is a double-layer electrical cabinet, including a rear box 1, a front box 2, and a front door 3. The rear box 1 houses high-voltage devices, a DC power supply, and a high-power heat dissipation assembly. The front box 2 houses DC components. The front door 3 is used to display the internal operating status of the front box. The rear box 1 and the front box 2 are connected by hinges. The side panel of the rear box 1 is equipped with a special lock 5 that is linked to and locked to the front box 2. The front door 3 is connected to the front box 2 by hinges. The back of the rear box 1 is equipped with a standardized slot 8, which includes horizontal slots and vertical slots that are perpendicularly distributed to each other. The side panel of the rear box 1 is equipped with a heat dissipation duct 6, and the heat dissipation duct 6 has a built-in cooling fan 7.

[0020] Specifically, the cooling fan 7 is electrically connected to the power supply and switch; the separate chamber design of the rear box 1 and the front box 2 achieves physical isolation between high-voltage and low-voltage components, solving the problems of low space utilization and electromagnetic interference; the cooperation between the cooling duct 6 and the cooling fan 7 improves the heat dissipation efficiency; the standardized card slot 8 allows the cabinet to be adapted to various installation methods such as wall mounting and column mounting, solving the problem of poor expandability; the linkage locking structure of the special lock 5 enhances the security of the cabinet.

[0021] In the above scheme, the opening of the front door 3 is covered with a transparent PC board 4, and the front door 3 is connected to the front enclosure 2 by a double-axis hinge. The transparent PC board 4 allows for real-time observation of the operating status of the components inside the front enclosure, reducing the frequency of opening the cabinet and avoiding accidental contact with high-voltage areas; the double-axis hinge allows the front door 3 to be fully opened 180°, facilitating comprehensive inspection and maintenance of the DC components inside the front enclosure 2, thus improving maintenance convenience.

[0022] In the above solution, the special lock 5 is a multi-point pin-type anti-pry structure, and its bolt is rigidly connected to the side plate of the rear box 1. The multi-point pin-type anti-pry structure and the rigidly connected bolt design effectively prevent unauthorized opening, improve the operational safety of high-voltage devices inside the rear box 1, and solve the problem of insufficient protection of traditional electrical cabinet locks.

[0023] In the above solution, the front box 2 and the rear box 1 are connected by a hinge that can rotate 90°. This hinge design supports quick separation and maintenance of the front box 2, enabling "hot-swappable" maintenance. Maintenance does not require a complete power outage, shortening downtime and solving the problem of inconvenient maintenance of traditional electrical cabinets.

[0024] In the above solution, both the rear box 1 and the front box 2 are made of cold-rolled steel plate or stainless steel plate. The high-quality cold-rolled steel plate or 304 stainless steel material combined with precision bending process ensures the overall rigidity, corrosion resistance and sealing of the electrical cabinet, making it suitable for harsh environments such as chemical plants and outdoor environments, and solving the problem of insufficient strength of traditional electrical cabinet materials.

[0025] In the above design, the rear box 1 has a depth of 236mm, the front box 2 has a depth of 145mm, and the front door 3 has a depth of 20mm. This reasonable cavity depth design optimizes space utilization. The rear box 1 can accommodate high-voltage devices and high-power heat dissipation components, the front box 2 meets the installation requirements of DC components, and the transparent design of the front door 3 does not occupy excessive space while ensuring good visibility of the status.

[0026] In the above scheme, an electromagnetic shielding layer 9 is provided between the rear box 1 and the front box 2. The electromagnetic shielding layer 9 is made of galvanized steel sheet. The electromagnetic shielding layer 9 made of galvanized steel sheet can effectively block the electromagnetic interference of the high-voltage devices in the rear box 1 to the DC components in the front box 2, improve the electromagnetic compatibility of the electrical cabinet, and ensure the stable operation of precision components.

[0027] Working principle:

[0028] This double-layer electrical cabinet has a rear compartment 1 for housing high-voltage components, DC power supplies, and high-power heat dissipation components, while the front compartment 2 independently houses DC components. Physical isolation allows for separate management of high-voltage and low-voltage equipment, reducing electromagnetic interference and improving space utilization. Opening the front door 3 allows direct operation of components within the front compartment 2. Unscrewing the front compartment 2 allows for independent maintenance of high-voltage components within the rear compartment 1 without requiring a complete power outage, enabling "hot-swap" maintenance and reducing downtime. The dedicated lock 5 on the side panel of the rear compartment 1 features a multi-point pin-type anti-pry structure, with the lock tongue rigidly connected to the side panel and mechanically linked to the front compartment 2 for locking, preventing unauthorized opening. The front door 3 is equipped with an industrial-grade lock cylinder, an emergency unlocking device, and is integrated with the cabinet's emergency power-off system. The system is integrated to ensure operational safety. The heat dissipation duct 6 on the side panel of the rear box 1 has a built-in cooling fan 7. The fan creates an air circulation channel to dissipate the heat generated by the high-voltage devices and high-power heat dissipation components during operation, improving the system's heat dissipation efficiency and ensuring stable equipment operation. An electromagnetic shielding layer 9 made of galvanized steel plate is set between the rear box 1 and the front box 2. This can effectively block the electromagnetic radiation generated by the high-voltage devices, reduce interference to the precision DC components in the front box 2, and meet electromagnetic compatibility requirements. The back of the rear box 1 integrates standardized slots 8, including horizontal and vertical slots that are perpendicular to each other. These slots are compatible with wall-mounted brackets or movable columns and other installation accessories, supporting flexible deployment in fixed or mobile scenarios to adapt to different application needs.
