Description

Technical Field

[0001] This utility model relates to the field of central cabinet technology, and in particular to a central cabinet with an isolation structure. Background Technology

[0002] Medium-voltage switchgear, also known as metal-clad medium-voltage withdrawable switchgear, is a type of high-voltage power distribution equipment. It is an indoor complete power distribution unit for three-phase AC 50Hz single-busbar or double-busbar segmented systems. It is used to receive and distribute 3.6-12kV network power and to control, protect, monitor, and measure power circuits. Medium-voltage switchgear is mainly used in power plants, for power transmission from small and medium-sized generators, for power receiving and transmission in secondary substations of power systems, for power distribution in industrial and mining enterprises, and for starting large high-voltage motors. Existing central switchgear has certain limitations in its structural design. The spaces for the instrument room, circuit breaker room, and cable room are mostly fixed. This fixed spatial layout is difficult to adapt to the diverse application scenarios and equipment upgrade needs of power systems. On the one hand, when it is necessary to replace circuit breakers, instruments, and other equipment of different specifications, or when the cable layout needs to be adjusted due to power network expansion or renovation, the fixed space cannot respond flexibly, resulting in restrictions on equipment installation and replacement, and even requiring large-scale renovation of the cabinet, increasing operation and maintenance costs and time. On the other hand, the fixed space is not conducive to the later inspection, maintenance, and optimization of the cabinet's internal layout, reducing the practicality and adaptability of the central switchgear and making it difficult to meet the development trend of modern power systems that are efficient, flexible, and intelligent. Therefore, this utility model proposes a central switchgear with an isolation structure to solve the above problems. Utility Model Content

[0003] To address the aforementioned problems, this utility model proposes a central switchgear with an isolation structure, which solves the problem that existing central switchgear has fixed spaces for the instrument compartment, circuit breaker compartment, and cable compartment, resulting in certain limitations during use.

[0004] To achieve the purpose of this utility model, the utility model is implemented through the following technical solution: a central cabinet with an isolation structure, including a central cabinet body, a door installed at the front end of the central cabinet body, two first partitions installed inside the central cabinet body, an adjustment mechanism provided on the outer side of the first partitions, an instrument compartment provided at the top inside the central cabinet body, a circuit breaker compartment provided at the middle position inside the central cabinet body, a cable compartment provided at the bottom inside the central cabinet body, and a separation mechanism provided at the top of the first partitions and above the bottom of the central cabinet body. The adjustment mechanism includes a rotating wheel, a first bevel gear, a second bevel gear, a threaded rod, a threaded sleeve, and a limiting structure. The rotating wheel is installed above and below one side of the central cabinet body. The first bevel gear is installed inside the central cabinet body. The output end of the rotating wheel is connected to one end of the first bevel gear. The second bevel gear meshes with the lower part of the first bevel gear. A threaded rod is installed at the bottom end of the second bevel gear. A threaded sleeve is provided on the outer wall of the threaded rod. One end of the threaded sleeve is connected to one end of the first partition plate.

[0005] A further improvement is that the limiting structure includes a limiting groove and a limiting block. The limiting groove is opened on the other side inside the main body of the central cabinet. A limiting block is set inside the limiting groove. One end of the limiting block is connected to one end of the first partition.

[0006] A further improvement is that the cross-section of the limiting groove is larger than the cross-section of the limiting block, and the limiting groove and the limiting block form a sliding structure.

[0007] A further improvement is made in that: the partition mechanism includes a second partition, a fixed groove, a movable block, a positioning hole, and a positioning pin. The second partition is installed above the top of the upper first partition and above the bottom of the interior of the central cabinet body. The fixed groove is opened in front of the upper first partition and the bottom of the interior of the central cabinet body. The movable block is provided inside the fixed groove. The top of the movable block is connected to the bottom of the second partition. The fixed groove and the movable block are provided with positioning holes. The positioning holes are provided with positioning pins.

[0008] A further improvement is that: multiple positioning holes are provided inside the fixing groove, and the multiple positioning holes are distributed at equal intervals inside the fixing groove.

[0009] A further improvement is that the positioning hole and the positioning pin are mutually adapted, and the positioning hole and the positioning pin form an engaging structure.

[0010] The beneficial effects of this utility model are as follows: By providing an adjustment mechanism on the outside of the first partition, the positions of the two first partitions can be adjusted separately through the cooperation of the rotating wheel, the first bevel gear, the second bevel gear, the threaded rod, the threaded sleeve, the limiting groove, and the limiting block of the adjustment mechanism. This allows for the adjustment of the space of the instrument compartment, the circuit breaker compartment, and the cable compartment, resulting in better performance of the central control cabinet. When replacing with a larger smart meter or control device, or adapting to circuit breaker trolleys of different lengths, the position of the first partition can be dynamically adjusted to optimize performance. The spatial allocation greatly improves the versatility of the central switch cabinet during use. By setting up a partition mechanism, the space between the instrument room and the circuit breaker room can be divided by the cooperation between the second partition, the fixed groove, the movable block, the positioning hole and the positioning pin of the partition mechanism. The terminal block area can be separated from the measurement and control device, or the size of the sub-compartment can be adjusted according to the number of secondary circuits to adapt to the wiring requirements of different projects. When the number of cable inlets changes, such as adding a new circuit, or when it is necessary to adjust the distance between the grounding switch and the cable joint, the first partition can be moved to redivide the space, avoiding the need to modify the cabinet.

[0013] To deepen the understanding of this utility model, the following detailed description will be provided in conjunction with embodiments. These embodiments are only used to explain this utility model and do not constitute a limitation on the scope of protection of this utility model.

[0014] according to Figure 1 , 2As shown in Figures 3, 4, and 5, this embodiment proposes a central control cabinet with an isolation structure, including a central control cabinet body 1. A door 2 is installed at the front end of the central control cabinet body 1. Two first partitions 3 are installed inside the central control cabinet body 1. An adjustment mechanism is provided on the outer side of the first partitions 3. An instrument compartment 4 is provided at the top inside the central control cabinet body 1. A circuit breaker compartment 5 is provided at the middle position inside the central control cabinet body 1. A cable compartment 6 is provided at the bottom inside the central control cabinet body 1. A separation mechanism is provided at the top of the first partitions 3 and above the bottom of the central control cabinet body 1.

[0015] The adjusting mechanism includes a rotating wheel 7, a first bevel gear 8, a second bevel gear 9, a threaded rod 10, a threaded sleeve 11, and a limiting structure. The rotating wheel 7 is installed above and below one side of the central cabinet body 1. The first bevel gear 8 is installed inside the central cabinet body 1. The output end of the rotating wheel 7 is connected to one end of the first bevel gear 8. The second bevel gear 9 meshes with the lower part of the first bevel gear 8. A threaded rod 10 is installed at the bottom end of the second bevel gear 9. A threaded sleeve 11 is provided on the outer wall of the threaded rod 10. One end of the threaded sleeve 11 is connected to one end of the first partition plate 3. In use, rotating the rotating wheel 7 drives the first bevel gear 8 to rotate, thus driving the second bevel gear 9 to rotate. The two bevel gears 9 rotate, which in turn drives the threaded rod 10 to rotate, thus moving the threaded sleeve 11. Under the limitation of the limiting groove 12 and the limiting block 13, the threaded sleeve 11 drives the first partition 3 to move, adjusting the space between the instrument compartment 4, the circuit breaker compartment 5, and the cable compartment 6. This makes the main body of the central switch cabinet 1 perform better in use. When replacing with a larger smart meter or control device, or adapting to circuit breaker trolleys of different lengths, the position of the first partition 3 is dynamically adjusted to optimize the space allocation. For example, when the cable compartment 6 needs to accommodate more incoming lines, the lower first partition 3 is raised to expand the height of the cable compartment 6, thereby greatly improving the versatility of the central switch cabinet in use.

[0016] The limiting structure includes a limiting groove 12 and a limiting block 13. The limiting groove 12 is located on the other side inside the main body 1 of the central cabinet. The limiting block 13 is provided inside the limiting groove 12. One end of the limiting block 13 is connected to one end of the first partition 3. The cross-section of the limiting groove 12 is larger than the cross-section of the limiting block 13. The limiting groove 12 and the limiting block 13 form a sliding structure. In use, the mutual cooperation between the limiting groove 12 and the limiting block 13 can limit the movement of the first partition 3, making the first partition 3 more stable when moving.

[0017] The partition mechanism includes a second partition 14, a fixing groove 15, a movable block 16, positioning holes 17, and positioning pins 18. The second partition 14 is installed above the top of the upper first partition 3 and above the bottom of the interior of the central cabinet body 1. The fixing groove 15 is located in front of the bottom of the interior of the upper first partition 3 and the central cabinet body 1. The movable block 16 is provided inside the fixing groove 15, and the top of the movable block 16 is connected to the bottom of the second partition 14. Positioning holes 17 are provided inside the fixing groove 15 and the movable block 16. Positioning pins 18 are provided inside the positioning holes 17. Multiple positioning holes 17 are provided inside the fixing groove 15, and the multiple positioning holes 17 are evenly distributed inside the fixing groove 15. The positioning holes 17 and positioning pins 18 are mutually adapted to each other. The positioning pins 18 form a locking structure. When it is necessary to separate the interior of the instrument compartment 4 and the cable compartment 6, the positioning pins 18 are pulled out from the positioning hole 17, and then the movable block 16 is moved inside the fixed groove 15, thereby moving the second partition 14. The second partition 14 is adjusted to an appropriate position, and finally the positioning pins 18 are inserted into the positioning hole 17 to fix the position of the second partition 14, thus completing the isolation of the interior space of the instrument compartment 4 and the cable compartment 6. This separates the terminal block area in the instrument compartment 4 from the measurement and control device, or adjusts the size of the sub-compartment according to the number of secondary circuits to adapt to the wiring requirements of different projects. When the number of cable inlets in the cable compartment 6 changes, such as adding a new circuit, or when it is necessary to adjust the distance between the grounding switch and the cable connector, the second partition 14 is moved to redivide the space, avoiding the need to modify the cabinet.

[0018] Working principle: The operator first rotates the rotating wheel 7, which drives the first bevel gear 8 to rotate, thus driving the second bevel gear 9 to rotate, which in turn drives the threaded rod 10 to rotate, thus driving the threaded sleeve 11 to move. Under the limitation of the limiting groove 12 and the limiting block 13, the threaded sleeve 11 drives the first partition 3 to move, adjusting the space between the instrument room 4, the circuit breaker room 5, and the cable room 6. When it is necessary to separate the interior of the instrument room 4 and the cable room 6, the positioning pin 18 is pulled out from the positioning hole 17, and then the movable block 16 is moved inside the fixed groove 15, which drives the second partition 14 to move. The second partition 14 is adjusted to an appropriate position, and finally the positioning pin 18 is inserted into the positioning hole 17 to fix the position of the second partition 14, completing the isolation of the interior space of the instrument room 4 and the cable room 6.
