Technical Field
[0001] This utility model relates to the field of switchgear design technology, and more specifically, to a power switchgear that can be quickly disassembled and repaired. Background Technology
[0002] Switchgear is a common electrical product used in power systems for switching, control, and protection in power generation, transmission, distribution, energy conversion, and consumption. Existing switchgear typically has a fixed internal structure, meaning the internal mounting racks are usually fixed to the cabinet. This requires electrical engineers to manually install each component on the racks, resulting in a disorganized component and wiring layout. Furthermore, when maintenance is needed, engineers must individually remove each component from the rack, making the process cumbersome and inefficient. Therefore, this paper proposes a power switchgear that allows for rapid disassembly and maintenance. Utility Model Content
[0003] (a) Technical problems to be solved
[0004] To address at least one of the aforementioned problems, this utility model first provides a power switchgear that can be quickly disassembled and repaired. The switchgear divides the components inside the switch cabinet into multiple independent configuration modules and simplifies the disassembly and assembly operations of the configuration modules and the switch cabinet, effectively improving its disassembly and repair efficiency.
[0005] (II) Technical Solution
[0006] To solve the aforementioned technical problem, this utility model provides a power switchgear that can be quickly disassembled and repaired, comprising multiple cabinet frame modules and mounting brackets. Each cabinet frame module includes a left support frame and a right support frame arranged symmetrically. The left support frame includes two left horizontal beams spaced vertically apart and two left vertical beams spaced front to back. The upper and lower ends of each left vertical beam are connected to the two left horizontal beams, respectively. The right support frame includes two right horizontal beams spaced vertically apart and two right vertical beams spaced front to back. The upper and lower ends of each right vertical beam are connected to the two right horizontal beams, respectively. The mounting bracket is provided with left and right insertion posts. The left vertical beams have multiple left insertion slots spaced vertically apart, and the right vertical beams have multiple right insertion slots spaced vertically apart. One of the left insertion slots is selectively connected to a left insertion post, and one of the right insertion slots is selectively connected to a right insertion post, enabling the left and right ends of the mounting bracket to be quickly disassembled and installed on the left and right vertical beams, respectively.
[0007] Furthermore, the left vertical beam is configured as a first contact end a at the bottom of the left insertion slot, and the left insertion post is configured as a second contact end b corresponding to the first contact end a. When the left insertion post is inserted into the left insertion slot, the left vertical beam establishes support control for the left end of the mounting frame.
[0008] Furthermore, the cabinet frame module is fixedly mounted on the switch cabinet, and the switch cabinet contains a first disassembly cabinet and a second disassembly cabinet arranged side by side according to the arrangement of the cabinet frame module.

Detailed Implementation
[0022] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.
[0023] See Figures 1 to 5This utility model provides a power switchgear that can be quickly disassembled and repaired, including multiple cabinet frame modules and mounting brackets 13. Each cabinet frame module includes a left support frame and a right support frame arranged symmetrically. The left support frame includes two left horizontal beams 11 spaced vertically and two left vertical beams 12 spaced front to back. The upper and lower ends of each left vertical beam 12 are connected to the two left horizontal beams 11, respectively. The right support frame includes two right horizontal beams spaced vertically and two right vertical beams spaced front to back. The upper and lower ends of each right vertical beam are connected to the two right horizontal beams, respectively. The front left and right vertical beams are arranged on the same vertical plane, and the rear left and right vertical beams are arranged on the same vertical plane. On the surface, the mounting bracket 13 is provided with a left plug-in post 15 and a right plug-in post. The left vertical beam 12 is provided with multiple left plug-in slots 14 spaced vertically, and the right vertical beam is provided with multiple right plug-in slots spaced vertically. One of the multiple left plug-in slots 14 is plugged into the left plug-in post 15, and one of the multiple right plug-in slots is plugged into the right plug-in post. This allows the left and right ends of the mounting bracket 13 to be quickly installed and removed from the left vertical beam 12 and the right vertical beam, respectively. The mounting bracket 13 is installed on two sets of vertical beams on the same vertical plane, so that the mounting bracket 13 is set independently as an electronic component module in the switch cabinet 1. The mounting bracket 13 carrying different electronic component modules can be independently installed and removed from the left support frame and the right support frame.
[0024] See Figure 4 and Figure 5 The left vertical beam 12 is set as the first contact end a at the bottom of the left insertion slot 14, and the left insertion post 15 is set as the second contact end b at the first contact end a. When the left insertion post 15 is inserted into the left insertion slot 14, the left vertical beam 12 establishes support control on the left end of the mounting frame 13. At this time, the first contact end a and the second contact end b abut against each other. Combined with the limiting effect of the left insertion slot 14 on the insertion post, the left end of the mounting frame 13 can be installed on the left vertical beam 12. The mounting frame 13 and the left vertical beam 12 are in a mutually perpendicular connection position relationship after the insertion assembly is completed.
[0025] The right insertion post has the same structure and connection method as the left insertion post 15. That is, the mounting bracket 13 inserts the left insertion post 15 into the left vertical beam 12, and then inserts the right insertion post into the insertion hole at the same height as the right vertical beam in the same vertical plane, so that the two sets of vertical beams can be connected to the mounting bracket 13.
[0026] The weight of the components and circuits on the mounting bracket 13 will cause the mounting bracket 13 to flip forward. By using the contact end to abut against the plug and the limiting effect of the plug slot on the plug post, the installation stability of the mounting bracket 13 and the components can be guaranteed. When the components on the mounting bracket 13 need to be inspected or replaced, the mounting bracket 13 can be directly pulled out from the left vertical beam 12 and the right vertical beam. The operation is simple and does not require any other operating tools.
[0027] See Figure 2The cabinet frame module is fixedly installed on the switch cabinet 1. Inside the switch cabinet 1, a first disassembly cabinet 6 and a second disassembly cabinet 7 are arranged side by side according to the arrangement of the cabinet frame modules. The first disassembly cabinet 6 includes two sets of cabinet frame modules. The height of the upper set of cabinet frame modules corresponds to the specifications of the first conventional cabinet 2, and the height of the lower set of cabinet frame modules corresponds to the specifications of the second disassembly cabinet 7. The second disassembly cabinet 7 has another set of cabinet frame modules. The specific settings and arrangement of the three sets of cabinet frame modules are designed by the power engineer. The design styles are rich and highly coordinateable.
[0028] The top of the second assembly / disassembly cabinet 7 is equipped with a first conventional cabinet 2, and a second conventional cabinet 3 is located next to the first conventional cabinet 2. The two sets of conventional cabinets are equipped with electrical components that are relatively stable in operation and have a relatively low maintenance frequency. The two sets of conventional cabinets adopt fixed horizontal beams, vertical beams and fixed installation structures that are bolted to the vertical beams, so as to realize the assembly and use of electronic components that have high operational safety, are not prone to failure and have a low maintenance frequency.
[0029] See Figure 1 and Figure 2 The top of the switch cabinet 1 is provided with a top cover 4. The inner cavity of the top cover 4 is provided with a first negative pressure fan setting chamber 41 corresponding to the first disassembly cabinet 6. The first negative pressure fan setting chamber 41 is provided with a first negative pressure fan. The top of the first negative pressure fan setting chamber 41 is provided with a first filter screen. By setting the first negative pressure fan to draw air from the first disassembly cabinet 6, airflow exchange can be carried out inside the first disassembly cabinet 6 to avoid the components inside the first disassembly cabinet 6 being affected by high temperature.
[0030] Next to the first negative pressure fan setting chamber 41, there is a second negative pressure fan setting chamber 42. The second negative pressure fan setting chamber 42 is equipped with a second negative pressure fan, and the top of the second negative pressure fan setting chamber 42 is equipped with a second filter screen. By setting the second negative pressure fan to draw air from the second disassembly cabinet 7 and the two sets of conventional cabinets, airflow exchange between the three sets of cabinets can be achieved, avoiding the components inside the cabinets from being affected by high temperature.
[0031] The top of the switch cabinet 1 is covered by a top cover 4 to ensure the integrity of the cabinet. The top cover 4 is used to connect to two sets of fixed hanging rings 5 at both ends. The installation device can move the switch cabinet 1 to the designated installation position by connecting to the two sets of fixed hanging rings 5, thereby improving the ease of movement of the switch cabinet.
[0032] See Figure 3The switch cabinet 1 has a support base 8 at its bottom, and two sets of grounding frames 81 at its bottom. Each grounding frame 81 has a contact frame 82 at its top. Both the grounding frame 81 and the contact frame 82 have independent extension frames 83 on their inner sides. Each extension frame 83 has several sets of positioning pin holes 84. The support base 8 establishes a connection between the two sets of grounding frames 81 and the two sets of contact frames 82, and the end face of the contact frame 82 establishes a connection with the bottom of the switch cabinet 1. The switch cabinet 1 has connecting pin frames at each positioning pin hole 84. The connecting pin frames are inserted into the positioning pin holes 84 to enhance the accuracy of the support for the switch cabinet 1. A first reinforcing shaft 85 is set between the two sets of grounding frames 81 to enhance its stability, and a second reinforcing shaft 86 is set between the two sets of contact frames 82 to enhance its stability, thus ensuring the overall structural performance of the support base 8.
[0033] The support base 8 is set at the bottom of the switch cabinet 1, and the switch cabinet 1 is suspended above the support base 8 to avoid direct contact between the switch cabinet 1 and the installation ground. The switch cabinet 1 and the support base 8 are movably connected, which can effectively select a suitable installation method for the switch cabinet 1.
[0034] The present invention provides a power switchgear that can be quickly disassembled and repaired. The switch cabinet 1 is aligned and installed on the support base 8 to establish a suspended installation of the switch cabinet 1. The switch cabinet 1 is designed with three sets of cabinet frame modules and each set of mounting brackets 13 for fixing, plugging and adjusting. This design makes the switch cabinet 1 meet the needs of the operating power engineer for the installation and arrangement of each set of components in the switch cabinet. Each mounting bracket 13 is plugged into its corresponding cabinet frame module. No special disassembly or assembly tools are required to process its plugging structure, reducing the disassembly and assembly steps and effectively improving its disassembly and assembly efficiency.
[0035] Although the disclosure is as stated above, the scope of protection of this disclosure is not limited thereto. Those skilled in the art can make various changes and modifications without departing from the spirit and scope of this disclosure, and all such changes and modifications will fall within the protection scope of this utility model.
