Description

Technical Field

[0001] This utility model relates to the technical field of electrical equipment, and in particular to a switch cabinet. Background Technology

[0002] With increasing demands for power stability in industrial and commercial facilities, traditional single-power supply methods can no longer meet modern needs. This is especially true in critical facilities such as hospitals and data centers, where even a brief power outage can lead to significant losses. However, existing switchgear typically lacks the capability to switch to backup power to ensure the continuity and security of power supply. Furthermore, the installation position of the busbar frame within the switchgear is generally fixed. During maintenance and repair, if the busbar frame or the copper busbars connected to it obstruct the maintenance area, the entire busbar frame needs to be disassembled, resulting in significant maintenance difficulties. Secondly, when designers modify the electrical layout within the cabinet (replacing electrical components or cabling), and the original location of the busbar frame cannot accommodate the modified layout, additional fixing structures or replacement of the switchgear are required, leading to low adaptability for cabinet layout optimization.

[0003] Therefore, based on the above-mentioned technical problems, this application proposes a switch cabinet that is easy to maintain and has high adaptability to optimized cabinet layout. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of the existing technology and provide a switch cabinet that is easy to maintain and can be adapted to changes in the cabinet layout.

[0005] To achieve the above objectives, this utility model provides a switch cabinet, including a cabinet body and a busbar compartment disposed inside the cabinet body. The busbar compartment is equipped with two adjustable side beams, a socket mounting component for connecting to an external backup power supply, and two busbar frames. The adjustable side beams are installed opposite each other at the lower middle position on both sides of the busbar compartment. At least two primary mounting grooves extending along the X-axis are formed on the top of each adjustable side beam. The busbar frames are mounted on the primary mounting grooves using pre-set screws, and the busbar frames can slide relative to each other within the primary mounting grooves along the X-axis. Three through-hole plug-in slots are provided on the busbar frames, equidistantly distributed along the X-axis. These plug-in slots are used for the interlocking installation of a pre-set first copper busbar, a second copper busbar, and a third copper busbar. A safety distance is provided between the outer side of the busbar frame and the inner wall of the cabinet body. The socket mounting component is installed between the two adjustable side beams, with the socket mounting component located at one end of the adjustable side beam and the busbar frame located at the other end of the adjustable side beam.

[0006] Furthermore, the socket mounting component comprises two mounting rods and a socket mounting plate, wherein the socket mounting plate is disposed between the two mounting rods; the socket mounting plate is provided with at least two sockets arranged along the Y-axis, wherein an external backup power supply is connected to the sockets through a pre-set power supply line; at least one connecting groove is formed on each end of the socket mounting plate, and at least two connecting holes extending along the Z-axis and connected to the connecting grooves are formed on both sides of the mounting rod, and at least two sets of secondary mounting grooves extending along the Z-axis are formed on the other end face, the secondary mounting grooves being used to connect the mounting rod to the side of the busbar compartment with pre-set screws.

[0007] Furthermore, a stop portion extending in the Z-axis direction is formed on one end of the adjustable side beam, the stop portion being used to limit the relative displacement of the busbar frame on the adjustable side beam when adjusting its installation position.

[0008] Furthermore, the cabinet is also equipped with electrical components and related cables for maintaining the normal operation of the switch cabinet.

[0009] The present invention adopts the above-described solution, and its beneficial effects are as follows: Unlike traditional busbar frames that can only be installed in a fixed position, in this embodiment, based on on-site installation requirements, the busbar frame is installed on the adjustable side beam after selecting the corresponding primary mounting slot. The busbar frame's specific installation position can be adjusted on the adjustable side beam. This allows for easier maintenance and repair later, preventing complete removal of the busbar frame when it or the copper busbars connected to it obstruct maintenance lines / components, thus reducing workload and operational difficulty. Similarly, when changing the electrical layout within the cabinet, adjusting the busbar frame's installation position allows for adaptation to the changed layout, improving applicability. Likewise, adding adjustable socket mounting components allows them to be adjusted according to changes in the cabinet's electrical layout. Furthermore, when socket mounting components obstruct maintenance lines / components, adjusting their relative position (changing the Z-axis / X-axis position) avoids the need for complete removal of the socket mounting components, further reducing workload and operational difficulty.

Detailed Implementation

[0016] To facilitate understanding of this utility model, a more complete description of it is provided below with reference to the accompanying drawings. The drawings illustrate preferred embodiments of the utility model. However, this utility model can be implemented in many different forms and is not limited to the embodiments described herein. These embodiments are provided to provide a more thorough and complete understanding of the disclosure of this utility model.

[0017] See appendix Figure 1-5 As shown, an XYZ axis spatial coordinate system is established. In this embodiment, a switch cabinet (its outer casing is not shown) includes a cabinet body 1 and a busbar compartment 11 disposed inside the cabinet body 1. Two adjustable side beams 2, a socket mounting component 3 for connecting to an external backup power supply, and two busbar frames 4 are installed inside the busbar compartment 11. The adjustable side beams 2 are installed at the lower center positions on both sides of the busbar compartment 11. At least two, preferably four, primary mounting grooves 21 extending along the X-axis are formed on the top of the adjustable side beams 2. The busbar frames 4 are secured by pre-set screws. Mounted on the primary mounting slot 21, the busbar frame 4 can slide relative to each other in the primary mounting slot 21 along the X-axis direction. The busbar frame 4 is provided with three plug-in slots 41 that are equidistantly distributed and pass through along the X-axis direction. The plug-in slots 41 are used for the pre-set first copper busbar, second copper busbar and third copper busbar to be snapped together. A safety distance 5 is provided between the outer side of the busbar frame 4 and the inner wall of the cabinet 1. The socket mounting part 3 is installed between two adjustable side beams 2. The socket mounting part 3 is located at one end of the adjustable side beam 2, and the busbar frame 4 is located at the other end of the adjustable side beam 2.

[0018] Specifically, the aforementioned copper busbars are energized during operation and must not come into direct contact with cabinet 1; otherwise, cabinet 1 will become energized, causing personal injury or death. Therefore, when attaching busbar frame 4 to both sides of the aforementioned copper busbars, please refer to the attached document. Figure 4As shown, a safety gap 6 still exists between the end of the copper busbar and the outer side of the busbar frame 4. Furthermore, when the busbar frame 4 is installed on the adjustable side beam 2, a safety distance 5 exists between the outer side of the busbar frame 4 and the inner wall of the cabinet 1. By setting the safety distance 5 and the safety gap 6, the distance between the end of the copper busbar and the inner wall of the cabinet 1 is further increased, preventing the copper busbar from directly contacting or getting too close to the inner wall of the cabinet 1, thus preventing the cabinet 1 from becoming energized and improving overall safety. Secondly, by setting a primary mounting slot 21 on the adjustable side beam 2, when the busbar frame 4 is installed onto any two primary mounting slots 21 using pre-set screws (the primary mounting slot 21 can be selected according to the electrical layout inside the cabinet), (First adjustment) The busbar frame 4 can slide relative to the primary mounting slot 21 to further adjust its position within the slot 21 (second adjustment). After determining the position, the busbar frame 4 is fixed to the adjustable side beam 2 using pre-set screws. This allows it to adapt to different electrical layouts within the cabinet, improving adaptability. Furthermore, during later maintenance, the screws securing the busbar frame 4 can be loosened. Based on the first and second adjustments described above, the position of the busbar frame 4 can be adjusted relative to allow for maintenance of related lines / components. This relatively avoids the need to disassemble the busbar frame 4 and related electrical components as a whole, reducing maintenance difficulty and improving work efficiency.

[0019] See appendix Figure 2 As shown, the socket mounting component 3 consists of two mounting rods 31 and a socket mounting plate 32, wherein the socket mounting plate 32 is disposed between the two mounting rods 31; the socket mounting plate 32 is provided with at least two sockets arranged along the Y-axis, wherein an external backup power supply is connected to the sockets through a pre-set power supply line; at least one, preferably four, connecting grooves 321 are formed on both ends of the socket mounting plate 32, and at least two connecting holes 312 extending along the Z-axis and connected to the connecting grooves 321 are formed on both sides of the mounting rods 31, and at least two sets of secondary mounting grooves 311 extending along the Z-axis are formed on the other end face, the secondary mounting grooves 311 being used to connect the mounting rods 31 to the side of the busbar chamber 11 with pre-set screws.

[0020] See appendix Figure 2As shown, it should be noted that when installing the socket mounting component 3, the operator can select the connection hole 312 to be used on the mounting rod 31 according to the actual situation, and then connect the connection hole 312 to the connection groove 321 with the pre-set screws, thereby specifically setting the position of the socket mounting plate 32 in the Z-axis direction to adapt to the electrical layout; secondly, several through holes are provided on the side of the busbar compartment 11 and the side of the adjustable side beam 2. The operator selects the through hole to be used and aligns it with the secondary mounting groove 311, and then connects the through hole to the secondary mounting groove 311 with the pre-set screws, thereby fixing the mounting rod 31 to both sides of the busbar compartment 11. This makes it convenient to loosen the screws on the secondary mounting groove 311 and adjust the position of the mounting rod 31 in the Z-axis or the position of the mounting rod 31 in the X-axis when the socket position (X-axis position) needs to be adjusted due to changes in the circuit layout in the later stage, thereby improving the adaptability of the switch cabinet in this embodiment to changes in the circuit layout.

[0021] In addition, the specific number of sockets can be set according to the actual situation. When the power supply to the electrical facilities controlled by the switch cabinet in this embodiment is interrupted due to maintenance of related lines or power outages, the external power supply equipment is connected to the above-mentioned sockets to provide emergency power supply, ensuring the normal operation of each electrical facility and guaranteeing the normal electricity use of residents or the normal production electricity use of enterprises.

[0022] See appendix Figure 5 As shown, in this embodiment, a stop portion 22 extending in the Z-axis direction is formed on one end of the adjustable side beam 2. The stop portion 22 is used to limit the relative displacement of the bus frame 4 on the adjustable side beam 2 when adjusting the installation position, so as to prevent the bus frame 4 from protruding from the end of the adjustable side beam 2 when moving along the X-axis direction.

[0023] See appendix Figure 1 As shown, the cabinet 1 is further equipped with electrical components and related cables for maintaining the normal operation of the switch cabinet, such as circuit breakers, voltage transformers and connecting wires.

[0024] The embodiments described above are merely preferred embodiments of this utility model and are not intended to limit the utility model in any way. Any modifications or alterations made by those skilled in the art to the technical solution of this utility model without departing from its scope are equivalent embodiments of this utility model. Therefore, all equivalent changes made based on the concept of this utility model without departing from its scope should be covered within the protection scope of this utility model.
