Description

Technical Field

[0001] This utility model relates to the field of low-voltage switchgear technology, specifically to a partitioned low-voltage switchgear cabinet. Background Technology

[0002] Low-voltage switchgear is a type of equipment used in the low-voltage distribution section of power systems. It is mainly used for opening, closing, controlling, and protecting electrical equipment during power generation, transmission, distribution, and energy conversion. It is typically installed in distribution rooms and is widely used in power plants, petroleum, chemical, metallurgical, textile, and high-rise building industries. A search revealed existing technology (announcement number: CN202421228195.0) for partitioned low-voltage switchgear cabinets. The document describes a design where "the cabinet is partitioned, with multiple drawers at the front and an integrated vertical cabinet structure at the rear, resulting in high space utilization and a compact structure; components belonging to the same circuit can be arranged in the same drawer structure, allowing for quick replacement of the drawer in case of a circuit failure without affecting the normal operation of other drawers, facilitating maintenance and repair; each drawer can be operated and maintained independently, reducing safety risks during operation; the cabinet itself is also a drawer, with multiple ventilation holes and a bottom-intake, top-exhaust design for good heat dissipation." However, the multiple-drawer structure in this existing switchgear increases airflow resistance, leading to a gradual decrease in heat dissipation from top to bottom within the cabinet. Utility Model Content

[0003] To overcome the shortcomings of existing technologies, a partitioned low-voltage switchgear cabinet is provided to solve the problem that the multiple drawer structure of existing switchgear increases airflow resistance, resulting in a gradual decrease in heat dissipation from top to bottom of the cabinet.

[0004] To achieve the above objectives, a partitioned low-voltage switchgear cabinet is provided, comprising: a low-voltage switchgear cabinet, wherein two sets of partitioned vertical plates are welded and fixed to the inner wall of the low-voltage switchgear cabinet.

[0005] Fireproof partitions are inserted into the vertical partition panels. The inner groove of the fireproof partition is tightly attached to the vertical partition panel surface through a sealing gasket. Connecting plates are welded to the upper and lower ends of the fireproof partition. The connecting plates are screwed to the inner wall of the low-voltage switch cabinet through fixing studs. Horizontal partition panels are slidably connected to the vertical partition panels through sliding grooves. Air supply hoods and exhaust hoods are fixed to the left and right sides of the low-voltage switch cabinet, respectively. Branch hoods are provided at the upper end of the air supply hood and the lower end of the exhaust hood. Air guides are opened on the side of the branch hoods and are correspondingly distributed at the ventilation slots on the side of the low-voltage switch cabinet.

[0006] Furthermore, a cabinet door is installed on the front face of the low-voltage switch cabinet; and the front surface of the fireproof partition is attached to the cabinet door. Three sets of ventilation slots are opened on the left and right sides of the low-voltage switch cabinet.

[0007] Furthermore, the inner wall of the low-voltage switch cabinet is provided with fixing holes; and fixing studs are screwed into the fixing holes. A cooling fan is installed in the lower cavity of the low-voltage switch cabinet.

[0008] Furthermore, a connecting slot is provided on the left side of the cooling fan; and the connecting slot is connected to the right side cavity of the air supply hood, and an air inlet is provided on the right side of the cooling fan.

[0009] Furthermore, the fireproof partition has a fireproof board interlayer in the middle, and the vertical partition plate has equidistant grooves on its sides. The horizontal partition plate is connected to the grooves on its left and right sides by sliders.

[0010] Furthermore, the partition vertical plate surface is provided with a porous ventilation surface; and the porous ventilation surface is distributed at intervals at the upper and lower ends of the slide groove.

[0011] Furthermore, a flow guide cavity is provided inside the branch cover, and a dustproof net is installed at the upper cavity opening of the exhaust hood.

[0012] The beneficial effects of this utility model are as follows: the partitioned low-voltage switchgear cabinet utilizes fireproof partitions inserted and fixed to the partition vertical plates, dividing the vertical plates into multiple independent and isolated spaces. Simultaneously, the partition horizontal plates, slidably connected to the inner side of the partition vertical plates, further divide the cabinet space, facilitating efficient partitioned installation and arrangement of various low-voltage equipment within the low-voltage switchgear. This ensures the safety and protection of the independently partitioned spaces within the low-voltage switchgear, reduces the risk of electrical faults in the partitioned low-voltage switchgear cabinet, and delivers outside air to the partitioned areas within the cabinet through three sets of branch hoods inside the air supply hood. The exhaust hood then discharges hot air from the partitioned areas of the low-voltage switchgear upwards, facilitating a more even and accelerated flow of hot air within the partitioned areas of the low-voltage switchgear, and enhancing the uniform heat dissipation effect of the partitioned low-voltage switchgear.

[0018] Reference Figures 1 to 4 As shown, this utility model provides a partitioned low-voltage switch cabinet, including: a low-voltage switch cabinet 1, with two sets of partitioned vertical plates 4 welded and fixed to the inner wall of the low-voltage switch cabinet 1.

[0019] Fireproof partitions 2 are inserted into the surface of the partition vertical plate 4. The inner groove of the fireproof partition 2 is tightly attached to the surface of the partition vertical plate 4 through a sealing gasket 21. Connecting plates 24 are welded to the upper and lower ends of the fireproof partition 2. The connecting plates 24 are screwed to the inner wall of the low-voltage switch cabinet 1 through fixing studs 22. Partition horizontal plates 3 are slidably connected at the intervals of the partition vertical plates 4 through sliding grooves 41. Air supply hoods 5 and exhaust hoods 51 are fixed to the left and right sides of the low-voltage switch cabinet 1, respectively. Branch hoods 52 are provided at the upper end of the air supply hood 5 and the lower end of the exhaust hood 51. Air guides 55 are opened on the side of the branch hoods 52 and are distributed at the ventilation slots 13 on the side of the low-voltage switch cabinet 1.

[0020] First, the low-voltage equipment is installed on the partitioned horizontal plate 3 that slides onto the partitioned vertical plate 4 inside the low-voltage switch cabinet 1, so that the low-voltage equipment is installed and arranged in partitioned areas. After installation, the fireproof partition 2 is inserted and fixed to the surface of the partitioned vertical plate 4, so that the low-voltage switch cabinet 1 is divided into multiple independent and isolated spaces. When the temperature in the independent and isolated spaces is too high, the cooling fan 15 delivers the cold air from outside the cabinet through the branch cover 52 of the air supply hood 5 to the upper, middle and lower areas inside the low-voltage switch cabinet 1. The cold air from outside the cabinet enters from the perforated ventilation surface 42 of the left partitioned vertical plate 4 into the gap of the partitioned vertical plate 4, so as to remove the heat of the low-voltage equipment on the partitioned horizontal plate 3. Then, it flows from the perforated ventilation surface 42 of the right partitioned vertical plate 4 to the upper cavity of the exhaust hood 51 and is discharged, thus realizing the heat dissipation path of left entry and right exit.

[0021] In this embodiment, a cabinet door 11 is installed on the front face of the low-voltage switch cabinet 1; and the front surface of the fireproof partition 2 is attached to the cabinet door 11. Three sets of ventilation slots 13 are opened on the left and right sides of the low-voltage switch cabinet 1. A fixing hole 12 is provided on the inner side wall of the low-voltage switch cabinet 1; and a fixing stud 22 is screwed into the fixing hole 12. A cooling fan 15 is installed in the lower cavity of the low-voltage switch cabinet 1. A connecting slot 14 is provided on the left side of the cooling fan 15; and the connecting slot 14 is connected to the right cavity of the air supply hood 5. An air inlet 16 is provided on the right side of the cooling fan 15.

[0022] In a preferred embodiment, the three sets of ventilation slots 13 facilitate the airflow between the upper part of the air supply hood 5 and the three sets of branch hoods 52 of the exhaust hood 51, enabling air circulation between the inside and outside of the low-voltage switch cabinet 1. The cooling fan 15 facilitates the delivery of cool air from outside the cabinet to the internal partitioned areas, allowing hot air inside the cabinet to be exhausted, thus achieving a cooling effect. The multiple sets of fixing holes 12 on the inner side wall of the low-voltage switch cabinet 1 allow for adjustment of the installation position and number of fireproof partitions 2.

[0023] In this embodiment, the fireproof partition 2 has a fireproof board interlayer 23 in the middle, and the partition vertical plate 4 has equidistant grooves 41 on its sides. The partition horizontal plate 3 is connected to the grooves 41 on its left and right sides by sliders 31. The partition vertical plate 4 has a perforated ventilation surface 42 on its surface; and the perforated ventilation surface 42 is distributed at intervals at the upper and lower ends of the grooves 41.

[0024] As a preferred implementation, the fireproof board interlayer 23 gives the fireproof partition 2 fireproof and flame-retardant properties, effectively preventing the spread of fire caused by electrical faults in the independent space separated by the fireproof partition 2 into another partitioned space. This facilitates efficient partitioned installation and arrangement of various low-voltage equipment within the low-voltage switchgear, ensuring the safety and protection of the independently partitioned spaces within the low-voltage switchgear and reducing the risk of electrical faults in the partitioned low-voltage switchgear cabinet. The partition vertical plates 4 and partition horizontal plates 3 allow for partitioned installation and arrangement of various low-voltage equipment, avoiding the impact of installing multiple low-voltage equipment together on daily maintenance. The perforated ventilation surface 42 facilitates the entry and exit of air flowing from the connecting slots 14 on both sides into the space between the partition vertical plates 4, thereby enhancing the heat dissipation effect of the partitioned areas within the low-voltage switchgear cabinet 1 through left-in and right-out airflow.

[0025] In this embodiment, a flow guide cavity 53 is provided inside the branch cover 52, and a dustproof net 54 is installed at the upper cavity opening of the exhaust cover 51.

[0026] As a preferred implementation, the airflow guide cavity 53 facilitates the input of air entering from the air supply hood 5 into the low-voltage switch cabinet 1 or the upward exhaust of hot air from the right-end ventilation slot 13, which facilitates zoned ventilation and heat dissipation, evenly accelerates the flow of hot air in the zoned areas of the low-voltage switch cabinet, and enhances the uniform heat dissipation effect of the zoned low-voltage switch cabinet. The dustproof net 54 helps to prevent external dust from entering the exhaust hood 51.

[0027] This utility model's partitioned low-voltage switchgear cabinet effectively solves the problem in existing switchgear where multiple drawer structures increase airflow resistance, leading to a gradual decrease in heat dissipation from top to bottom within the cabinet. It facilitates efficient partitioned installation and arrangement of various low-voltage equipment within the low-voltage switchgear, ensuring the safety and protection of independently separated spaces within the cabinet. It reduces the risk of electrical faults in the partitioned low-voltage switchgear cabinet, and promotes balanced and accelerated hot air flow within the partitioned areas, enhancing the uniform heat dissipation effect of the partitioned low-voltage switchgear. It is suitable for partitioned low-voltage switchgear cabinets.
