Abstract
Description
Technical Field
[0001] This utility model relates to the field of high voltage switchgear technology, and in particular to a modular high voltage switchgear. Background Technology
[0002] In today's power system, high-voltage switchgear is a key piece of equipment for ensuring stable power transmission, distribution and control, and its importance is self-evident. With the rapid development of the social economy, the demand for electricity in various fields continues to rise. Whether it is large-scale urban construction, industrial expansion or the rise of new energy industries, all of these have prompted the continuous upgrading and transformation of power infrastructure. Against this background, more stringent requirements have been put forward for the performance, ease of installation and maintenance costs of high-voltage switchgear.
[0003] Traditional high-voltage switchgear has revealed many drawbacks in practical applications. Most traditional high-voltage switchgear adopts an integral structure and is assembled before leaving the factory. This results in its large size and heavy weight, which poses many difficulties during transportation. On the one hand, it occupies a lot of transportation space, which limits the amount that can be transported at one time and increases transportation costs significantly. On the other hand, when encountering bumps and collisions, high-voltage switchgear with an integral structure is very easy to be damaged. Moreover, because the components are tightly integrated, the repair or replacement of local damage is extremely difficult, further increasing the cost of use. Utility Model Content

[0013] (III) Beneficial Effects
[0014] This utility model provides a modular high-voltage switchgear. It has the following advantages:
[0015] 1. The modular splicing design allows for quick assembly of the rear and side panels via sliding connections. Components such as the top cover, reinforcing plate, and ventilator are fixed with bolts, which simplifies the installation process and facilitates disassembly and adjustment during later maintenance. At the same time, the ventilator on the side panel can be fixed in place by bolts through the mounting slots and mounting ears to ensure the continuous and effective heat dissipation function and reduce the impact of high temperature on equipment performance.
[0016] 2. The core support frame is constructed by the fixed connection between the base plate and multiple sets of slot columns. With the sliding embedding of the rear plate and side plates and the threaded seal of the top cover plate, a complete enclosed cabinet is formed. This effectively prevents the intrusion of external debris such as dust and moisture, creating a clean operating environment for high-voltage equipment. At the same time, the "X"-shaped reinforcing plates on the surface of the rear middle and rear side slot columns use the principle of triangular stability to distribute the equipment's own weight and external impact forces to each slot column, greatly reducing the risk of local deformation, ensuring the long-term stability of the frame, providing reliable structural support for the internal equipment, and ensuring the safety of the high-voltage system operation.

[0023] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.
[0024] Reference Figures 1 to 4 As shown, this utility model provides a technical solution: a modular high-voltage switchgear, including a base plate 1. A front middle slot column 3 and a rear middle slot column 2 are fixedly connected to the surface of the base plate 1. Front side slot columns 5 are provided on both sides of the front middle slot column 3, and the lower end of the front side slot column 5 is fixedly connected to the surface of the base plate 1. Rear side slot columns 4 are provided on both sides of the rear middle slot column 2, and the lower end of the rear side slot column 4 is fixedly connected to the surface of the base plate 1. A rear plate 18 is slidably connected between the rear side slot column 4 and the rear middle slot column 2. A side plate 12 is slidably connected between the front side slot column 5 and the rear side slot column 4. Through the fixed connection between the base plate 1 and the front middle slot column 3, the rear middle slot column 2, the front side slot column 5, and the rear side slot column 4, a stable support structure is constructed, providing a reliable installation carrier for high-voltage equipment. The rear plate 18 and the side plate 12 are assembled between the corresponding slot columns by a sliding connection, realizing modular splicing, getting rid of the limitations of traditional welding or complex bolt fixing, greatly improving the efficiency of installation and disassembly, and reducing the assembly difficulty and time cost.
[0025] Reference Figure 2 , Figure 3 and Figure 4As shown in this embodiment: The tops of both the front channel column 5 and the rear channel column 4 are provided with fixing holes 6, and an upper cover plate 7 is provided above the front channel column 5 and the rear channel column 4. Fixing bolts 8 are provided at the four corners of the upper cover plate 7, and the fixing bolts 8 are threadedly connected to the inner walls of the fixing holes 6. The surfaces of both the rear middle channel column 2 and the rear channel column 4 are provided with reinforcing grooves 10. Reinforcing plates 11 are fixedly connected to the inner walls of the reinforcing grooves 10 by bolts. The number of reinforcing plates 11 is set to four sets, and the cross-section of the reinforcing plates 11 is "X" shaped. The fixing holes 6 at the tops of the front channel column 5 and the rear channel column 4, combined with the fixing bolts 8 at the corners of the upper cover plate 7, are threadedly connected to the upper cover plate 7. The top cover 7 is tightly fixed to the frame, preventing it from loosening or shifting. It also effectively blocks dust, rainwater, and other external debris from entering the cabinet, providing a cleaner operating environment for the high-voltage equipment. Meanwhile, the reinforcing grooves 10 on the surfaces of the rear middle column 2 and the rear side column 4, along with four sets of reinforcing plates 11 fixed by bolts, distribute the longitudinal and transverse stresses on the cabinet to each column. By utilizing the principle of triangular stability, the deformation resistance of the columns is greatly improved. Especially when the cabinet bears the weight of the high-voltage equipment, encounters external impacts, or is used for a long time, it can reduce the risk of structural shaking and deformation, and enhance the overall load-bearing capacity and structural stability.
[0026] Reference Figure 1 and Figure 4 As shown, specifically, the side plate 12 has mounting slots 13 on its surface. The inner wall of the mounting slots 13 is fixedly connected to mounting ears 15 by bolts. One end of the mounting ears 15 is fixedly connected to a mounting frame 14. The surface of the mounting frame 14 is fixedly connected to a vent plate 16. The surface of the front channel column 5 is hinged to a door 9. A partition plate 17 is provided between the front middle channel column 3 and the rear middle channel column 2. The mounting ears 15 are fixedly connected to the mounting slots 13 on the surface of the side plate 12 by bolts, which can ensure the positional stability of the mounting ears 15 and the mounting frame 14 and prevent the vent plate 16 from shifting or loosening due to vibration during equipment operation. The vent plate 16 on the surface of the mounting frame 14 continuously provides an air circulation channel for the internal equipment, reducing the impact of high temperature accumulation on equipment performance. At the same time, the door 9 hinged to the front channel column 5 facilitates daily inspection and operation of the internal equipment by operators. When closed, it can effectively isolate external dust, moisture and debris, creating a closed and clean operating environment for the equipment.
[0027] Working Principle: Using the base plate 1 as the foundation, the front middle channel column 3, rear middle channel column 2, front side channel column 5, and rear side channel column 4, which are fixedly connected, form the core support frame, creating a three-dimensional installation space. The rear plate 18 and side plates 12 are slidably embedded between the corresponding channel columns, quickly completing the enclosure around the cabinet. The top is then sealed via a threaded connection between the top cover plate 7 and the fixing holes 6 at the top of the channel columns. This completes the enclosed cabinet structure, providing a basic installation carrier for high-voltage equipment. Meanwhile, the "X" marks on the surfaces of the rear middle channel column 2 and rear side channel column 4... The reinforcing plate 11 is fixed to the reinforcing groove 10 with bolts. Utilizing the principle of triangular stability, it distributes the weight of the equipment and external impacts on the cabinet to each groove column, avoiding local structural deformation and ensuring the frame remains stable during long-term use. This provides reliable structural support for the internal equipment. Furthermore, the mounting slots 13 and mounting ears 15 on the side plate 12 are fixed with bolts, allowing the mounting frame 14 and the vent plate 16 to be stably installed in the required positions. The vent plate 16 dissipates heat from the internal equipment through air circulation, preventing high temperatures from affecting operational performance. The hinged door 9 on the front groove column 5 can be opened flexibly, facilitating maintenance and operation of the internal equipment. When closed, it forms a closed space with the cabinet, preventing the intrusion of external dust and moisture. The partition plate 17 divides the interior of the cabinet into different functional areas, achieving an orderly layout of the equipment and reducing mutual interference.
