Description

Technical Field

[0001] This utility model relates to the field of electrical cabinet technology, specifically to an insulating support base for high-voltage electrical cabinets. Background Technology

[0002] With the continuous development and widespread application of power systems, high-voltage electrical equipment, as a core component for power transmission, distribution, and control, plays a crucial role in ensuring the safety and stability of its operation. High-voltage electrical cabinets, as key equipment housing various high-voltage electrical components, are widely used in substations, power plants, industrial and mining enterprises, undertaking the important task of power conversion and distribution. However, due to the high voltage and large current inside high-voltage electrical cabinets, if an arc fault occurs and is not effectively isolated, it could potentially lead to serious safety accidents, threatening equipment and personnel safety. Therefore, ensuring reliable insulation between the high-voltage electrical cabinet and the ground, and possessing good adaptability and adjustment capabilities, has become a pressing technical challenge in the design and application of high-voltage electrical equipment.

[0003] Currently, although there are various support and insulation devices available on the market for high-voltage electrical cabinets, these traditional devices often have the following limitations: First, their protective performance is insufficient, making it difficult to effectively isolate the high-voltage electrical cabinet from the surrounding environment, especially in humid, dusty, or corrosive environments, where the risk of electric arc contact with the external ground remains high; second, their versatility is poor, requiring customized support devices of specific sizes for different models and specifications of high-voltage electrical cabinets, which not only increases production costs but also limits the flexible application of the products; finally, they lack effective vibration damping and adjustment mechanisms, making it difficult to provide stable support and appropriate protective spacing for high-voltage electrical cabinets of different weights and complex and changing operating environments, thus affecting the overall operating performance and lifespan of the equipment. Utility Model Content

[0004] To address the aforementioned technical problems, this utility model proposes the following technical solution: An insulating support base for a high-voltage electrical cabinet includes an isolation base, a high-voltage electrical cabinet, and an isolation pad. The isolation base is rectangular in shape to support the bottom of the high-voltage electrical cabinet. An isolation pad is provided at the bottom of the isolation base to isolate the bottom of the high-voltage electrical cabinet from the ground. The isolation pad is made of flexible rubber. The isolation base is composed of multiple main supports, which are the main structure of the isolation base. A wide-side partition is slidably installed on one side of the main support. A wide-side partition has multiple arc-shaped grooves on one side and serves as an extension of the main support. A main handle is rotatably installed on the side of the main support where the wide-side partition is located. A switch rod is provided on the main handle. In the initial state, the arc-shaped surface of the switch rod fits into the arc-shaped grooves on the wide-side partition, thereby securing the wide-side partition onto the main support.

[0005] Furthermore, the isolation seat is provided with two sets of mounting beams, and bolt mounting holes are provided at both ends of the mounting beams. Adjusting bolts are provided in the isolation seat; a support component is provided in the main bracket.

[0006] Furthermore, the mounting beam consists of a fixed beam, a sliding beam, and an embedded rod. The fixed beam is rotatably connected to the switch rod and also contacts the bolt mounting groove on the inner side of the main bracket. The embedded rod, as an extension of the sliding beam, is fixedly connected to the sliding beam and is slidably installed inside the fixed beam. The bottom of the embedded rod is provided with multiple limiting arc-shaped grooves, which have the same function as the arc-shaped grooves on the wide-side partition. The limiting arc-shaped grooves are used to fit the arc-shaped surface of the switch rod.

[0007] Furthermore, the support assembly includes a support leg, a buffer spring, a knob, and a threaded post. The support leg is slidably installed inside the main bracket to support the main bracket. The threaded post is fixedly installed inside the main bracket. The threaded post and the knob are connected by threads. A buffer spring is provided between the knob and the support leg. The buffer spring is used to buffer the main bracket and the support leg. The two ends of the buffer spring are fixedly connected to the knob and the support leg, respectively. The initial preload of the buffer spring can be adjusted by the knob. All support components are made of metal materials, and the material of the support leg needs to be rust-proof.

[0008] Furthermore, a long side partition is slidably installed on one side of the main support, and the other end of the long side partition is fixed on the main support on the same side. A plurality of locking grooves are provided on one side of the long side partition. A secondary handle is rotatably installed on the main support. The secondary handle rotates inside the main support, and the arc-shaped surface on the secondary handle matches the locking grooves on the long side partition.

[0009] Furthermore, a buffer pad is fixedly installed on the support leg to prevent the threaded column from colliding with the support leg; the buffer pad is made of rubber.

[0010] Compared with the prior art, the advantages of this utility model are: (1) This device adjusts the distance between the isolation seat and the installation beam to adapt the device to the bottom of the high voltage electrical cabinet, which not only improves the applicability of the device, but also allows the device to be tightly connected to the high voltage electrical cabinet, thus improving the isolation effect after installation; (2) This device adjusts the horizontal state of the high voltage electrical cabinet during installation through the support component, so that the high voltage electrical cabinet is kept horizontal during installation. At the same time, the support component can also play a shock absorption role for the high voltage electrical cabinet, thereby ensuring the operating environment of the high voltage electrical cabinet and preventing the bolts or structural parts of the high voltage electrical cabinet from loosening due to vibration.

Detailed Implementation

[0021] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0022] Example 1: This embodiment provides an insulating support base for a high-voltage electrical cabinet, such as... Figures 1 to 3 As shown, it includes an isolation seat 10, a high-voltage electrical cabinet 20, and an isolation pad 30. The isolation seat 10 is rectangular in shape and is used to support the bottom of the high-voltage electrical cabinet 20. An isolation pad 30 is provided at the bottom of the isolation seat 10 to isolate the bottom of the high-voltage electrical cabinet 20 from the ground. The isolation pad 30 is made of rubber. The isolation seat 10 is provided with two sets of mounting beams. The two ends of the mounting beams are provided with bolt mounting holes. The main support 101 is provided with bolt mounting grooves on the inner side. The mounting beams are installed on the bolt mounting grooves on the inner side of the main support 101 by adjusting bolts 206. During specific installation, the mounting beams can be adjusted to the installation position on the inner side of the main support 101 according to the specific installation position of the high voltage electrical cabinet 20. The main support 101 is provided with a support component to support the isolation seat 10.

[0023] Example 2: This embodiment further expands upon the isolation seat 10 based on Embodiment 1, specifically as follows: Figures 2 to 5 As shown, the isolation seat 10 is composed of multiple main supports 101. The main supports 101 are the main structure of the isolation seat 10. A long side partition 102 is slidably installed on one side of the main support 101. The other end of the long side partition 102 is fixed on the main support 101 on the same side. The long side partition 102 is used as an extension of the main support 101. The long side partition 102 is made of insulating material. Multiple locking grooves are provided on one side of the long side partition 102. A secondary handle 103 is rotatably mounted on the main support 101. The secondary handle 103 rotates within the main support 101. In its initial state, the secondary handle 103 engages with the locking groove on the long side partition 102. The secondary handle 103 is used to fix the long side partition 102 to the main support 101. After the secondary handle 103 rotates a certain angle, the arc surface of the long side partition 102 disengages from the long side partition 102. At this time, the long side partition 102 can slide on one side of the main support 101, thus allowing one side of the device to extend to accommodate isolation seats 10 of different lengths.

[0024] Example 3: This embodiment further expands upon the isolation seat 10 based on embodiment 2, specifically as follows: Figures 2 to 5As shown, a wide-side partition 104 is slidably mounted on one side of the main support 101. Multiple arc-shaped grooves are provided on one side of the wide-side partition 104. The wide-side partition 104 serves as an extension of the main support 101, and its function is the same as that of the long-side partition 102. The length of the wide-side partition 104 can be determined according to production needs. A main handle 201 is rotatably mounted on the side of the main support 101 where the wide-side partition 104 is located. A switch rod 202 is provided on the main handle 201. The cross-section of the switch rod 202 consists of an arc and a straight line. The arc surface of the switch rod 202 is used to limit the movement of the wide-side partition 104, while the flat surface of the switch rod 202 prevents it from contacting the wide-side partition 104. When it is necessary to move the wide-side partition 104... 4. When fixed on the main bracket 101, the main handle 201 can be rotated to make the arc-shaped surface on the switch rod 202 fit with the arc-shaped groove on the wide side partition 104, so that the wide side partition 104 will be stuck on the main bracket 101. Conversely, when adjusting the distance between the two main brackets 101, the main handle 201 is rotated to make the arc-shaped surface of the switch rod 202 disengage from the arc-shaped groove of the wide side partition 104, so that the wide side partition 104 can slide on the main bracket 101, thereby adjusting the distance between the main brackets 101 to adapt to different widths of the high-voltage electrical cabinet 20. The main bracket 101, long side partition 102, auxiliary handle 103, and switch rod 202 in the isolation seat 10 are all made of insulating materials, such as high-density polyethylene and polycarbonate.

[0025] Example 4: This embodiment further expands upon the installation of the crossbeam based on Embodiment 1, specifically as follows: Figures 3 to 7 As shown, the mounting beam consists of a fixed beam 203, a sliding beam 204, and an embedded rod 205. The fixed beam 203 is rotatably connected to the switch rod 202 and also contacts the bolt mounting groove on the inner side of the main bracket 101. The embedded rod 205, as an extension of the sliding beam 204, is fixedly connected to the sliding beam 204. The embedded rod 205 is slidably installed inside the fixed beam 203, and the bottom of the embedded rod 205 is provided with multiple limiting arcs. The limiting arc groove on the embedded rod 205 has the same function as the arc groove on the wide side partition 104. The limiting arc groove is used to fit with the arc surface of the switch rod 202, so that the embedded rod 205 is fixed on the fixed crossbeam 203 by the switch rod 202. After the arc surface of the switch rod 202 is disengaged from the limiting arc groove, the distance between the fixed crossbeam 203 and the sliding crossbeam 204 can be adjusted so that the installation crossbeam can be extended or shortened to adapt to the size of the installation bottom of the high voltage electrical cabinet 20. Both the fixed crossbeam 203 and the sliding crossbeam 204 are provided with bolt mounting slots, so as to facilitate the use of bolts to fix the high-voltage electrical cabinet 20 to the mounting crossbeam. The mounting crossbeam is made of insulating material, such as high-density polyethylene and polycarbonate.

[0026] Example 5: This embodiment further expands the support components based on Embodiment 1, specifically as follows: Figure 3 , Figure 4 , Figure 8 , Figure 9 As shown, the support assembly includes a support leg 301, a buffer spring 303, a knob 304, and a threaded post 305. The support leg 301 is slidably installed inside the main bracket 101 to support the main bracket 101. The threaded post 305 is fixedly installed inside the main bracket 101. The threaded post 305 is threadedly connected to the knob 304. A buffer spring 303 is provided between the knob 304 and the support leg 301. The buffer spring 303 is used to buffer between the main bracket 101 and the support leg 301. The two ends of the buffer spring 303 are fixedly connected to the knob 304 and the support leg 301, respectively. The initial preload of the buffer spring 303 can be adjusted by the knob 304. All support components are made of metal materials, and the material of the support leg 301 needs to be rust-proof. A buffer pad 302 is fixedly installed on the support leg 301 to prevent the threaded post 305 from colliding with the support leg 301. The buffer pad 302 is made of rubber.

[0027] Specific working methods: During installation, this device is adjusted according to the size of the bottom of the high-voltage electrical cabinet 20. Specifically, by rotating the auxiliary handle 103 and the main handle 201, the distance between the four main supports 101 is adjusted. During adjustment, the long side partition 102 extends the main support 101 to fill the gap between two main supports 101. The wide side partition 104 serves the same purpose as the long side partition 102. After adjusting the distance between each main support 101, rotating the auxiliary handle 103 and the main handle 201 locks the wide side partition 104 and the long side partition 102, thus fixing the isolating seat 10. When adjusting the distance between two main supports 101 after rotating the main handle 201, the fixed crossbeam 203 and the sliding crossbeam 204 are also adjusted simultaneously, thus adapting the device to the bottom of the high-voltage electrical cabinet 20. This not only improves the applicability of the device but also ensures a tight connection between the device and the high-voltage electrical cabinet 20.

[0028] After the high-voltage electrical cabinet 20 is bolted onto the mounting beam, its installation status needs to be checked for horizontality. This can be achieved by adjusting the support components. Specifically, this is done by rotating knob 304 to adjust its position, which in turn adjusts the position of support leg 301 on the ground. This adjustment balances the high-voltage electrical cabinet 20 mounted on the isolation seat 10. Simultaneously, the buffer spring 303 provides shock absorption, ensuring the high-voltage electrical cabinet 20 operates in a safe environment and reducing the risk of bolts or structural components loosening due to vibration. After the isolation seat 10 is deployed, an isolation pad 30 needs to be laid under the high-voltage electrical cabinet 20 to isolate it from cement, soil, or other ground surfaces. The isolation pad 30 is not flush with the ground; it is supported by support leg 301, thus separating it from the ground to prevent liquid from entering.

[0029] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the scope of protection of the present utility model.
