Description

Technical Field

[0001] The utility model relates to the technical field of low-voltage switch cabinets, in particular to a modular low-voltage switch cabinet. Background Art

[0002] Low-voltage switchgear is a complete set of distribution equipment consisting of one or more low-voltage switchgear and corresponding control, protection, measurement, signal, and regulation devices, as well as all internal electrical and mechanical interconnections and structural components. There are many types of low-voltage switchgear and they are widely used in various places. They are used in distribution systems at all levels of the entire low-voltage power grid.

[0003] After searching, a Chinese patent discloses a standardized low-voltage switch cabinet (authorization announcement number CN217823757U), including a cabinet body, and two auxiliary structures are arranged inside the cabinet body. The surface of the square plate is fixedly connected to the cabinet body, and four vertical plates are fixedly connected to the lower surface of the square plate. The surfaces of the four vertical plates are fixedly connected to round rods, and the arc surface of the round rod is slidably connected to a slide plate. The arc surface of the round rod is sleeved with a first spring, and the two ends of the first spring are respectively fixedly connected to the slide plate and the round rod. Although the patented technology can be provided by arranging square plates, vertical plates, round rods, slide plates, first springs, and desiccant bags, when the air is relatively humid, the staff can use the slide plate to cooperate with the elastic force of the first spring to place the desiccant bag at the position of the ventilation hole on the cabinet body, thereby achieving the effect of absorbing water vapor entering from the ventilation holes on the cabinet body surface, and trying to avoid the water vapor in the air from entering the interior of the cabinet body, thereby improving the moisture-proof effect of the cabinet body to a certain extent.

[0004] However, the above device still has some shortcomings in actual use. The most obvious one is that at present, traditional low-voltage switchgear is usually customized in design and production, which not only affects production efficiency, but also increases the difficulty and cost of subsequent maintenance. In order to improve production efficiency and flexibility of use, the demand for modular design is becoming increasingly prominent. Utility Model Content

The second card slots 11 are respectively engaged with the corresponding second card members 10. On the outside of one of the side panels 3, a closing door 5 is rotatably connected through a hinge. When assembling the low-voltage switchgear cabinet, the first card members 7 above the bottom plate 19 can be slid into the first card slots 8 at the bottom ends of the two side panels 3, and then the rear panel 9 is slid along the outer wall of the side panel 3, so that the second card members 10 on the rear panel 9 are engaged with the second card slots 11 on the side panel 3. Then, the first card members 7 on the top plate 2 are slid into the first card slots 8 at the top ends of the side panels 3. Finally, the closing door 5 is installed on one side of the side panel 3 through a hinge, thus realizing the modular design of the low-voltage switchgear cabinet. And each component in this modular design can be distributed to other factories for simultaneous production, which can improve production efficiency and usage flexibility. At the same time, if a single cabinet board is damaged, the corresponding independent board can be replaced, which reduces the difficulty and cost of later maintenance, and can meet the requirements of modular design.

[0030] Refer to Figure 2 , On the outside of the top plate 2, a clamping mechanism is provided. The clamping mechanism includes a first clamping strip fixedly connected to the bottom end of the rear panel 9. Inside the bottom plate 19, a first horizontal slot for cooperating with the first clamping strip is opened. The first horizontal slot is engaged with the first clamping strip. On the side of the top plate 2 close to the rear panel 9, a second clamping strip is fixedly connected.

And through the cooperation of the second horizontal slot and the second clamping strip, the connection tightness among the top plate 2, the rear panel 9 and the side panel 3 can be enhanced, and thus the overall assembly of the low-voltage switchgear cabinet can be made more stable.

[0031] Refer to Figure 4 , On the top end of the bottom plate 19, three functional modules 6 are provided. On the outside of the functional modules 6, an assembling mechanism is provided.

When assembling the data fittings of the two functional modules 6, the connection plug 13 on one functional module 6 can be docked with the connection fitting 14 on the other functional module 6. Under the action of the torsion spring 17, the L-shaped clamping plate 15 can be driven to rotate, so that the L-shaped clamping plate 15 abuts against the corresponding card hole 16, thereby enabling quick connection and forming a complete switch cabinet system.

[0033] Refer to Figure 2 Four corners inside the side plate 3 are all threadedly connected with locking bolts 12. One end of each locking bolt 12 extends into the corresponding first clamping groove 8 and abuts against the outer side of the first clamping part 7. By using the locking bolts 12, the overall stability of the low-voltage switch cabinet can be further improved, making each component not easy to loosen.

[0035] Working principle: First, when assembling the low-voltage switchgear cabinet, the first clamping part 7 above the bottom plate 19 can be slid into the first clamping grooves 8 at the bottom ends of the two side plates 3, and then the rear plate 9 is slid along the outer wall of the side plate 3, so that the second clamping part 10 on the rear plate 9 is clamped with the second clamping groove 11 on the side plate 3. Then, the first clamping part 7 on the top plate 2 is slid into the first clamping groove 8 at the top end of the side plate 3. By the cooperation of the first transverse groove and the first clamping strip, the connection strength among the bottom plate 19, the side plates 3 and the rear plate 9 can be enhanced, making the connection among the three more compact and not prone to looseness. By the cooperation of the second transverse groove and the second clamping strip, the connection tightness among the top plate 2, the rear plate 9 and the side plates 3 can be enhanced, thereby making the overall assembly of the low-voltage switchgear cabinet more stable. Finally, the closing door 5 is installed on one side of the side plate 3 through a hinge, thus realizing the modular design of the low-voltage switchgear cabinet. Each component in this modular design can be assigned to other factories for simultaneous production, which can improve production efficiency and usage flexibility. At the same time, if a single cabinet board is damaged, the corresponding independent board can be replaced, reducing the difficulty and cost of later maintenance, and thus meeting the requirements of the modular design;

[0036] When assembling the data accessories of the two functional modules 6, the connection plug-in 13 on one functional module 6 can be docked with the connection fitting 14 on the other functional module 6. Through the action of the torsion spring 17, the L-shaped clamping plate 15 can be driven to rotate, so that the L-shaped clamping plate 15 abuts against the corresponding clamping hole 16, thereby enabling quick connection and forming a complete switchgear cabinet system, ensuring the interchangeability and compatibility among the functional modules 6.
