Description

Technical Field

[0001] This utility model relates to the field of modular power distribution cabinets, and more specifically, to a modular combined low-voltage power distribution cabinet. Background Technology

[0002] With the development of the power industry and intelligent manufacturing, low-voltage switchgear is being used more and more widely in power systems. Low-voltage switchgear is used to centrally install various low-voltage electrical appliances, measuring instruments, protective devices, and auxiliary equipment to ensure the normal operation and safety of the power grid.

[0003] Most existing low-voltage distribution cabinets adopt a fixed structure design. When it is necessary to combine and install low-voltage distribution cabinets, they cannot be combined because there is no connection between the individual distribution cabinets. Secondly, due to special needs, it is sometimes necessary to connect or extend the lines or components in some distribution cabinets to other distribution cabinets. However, since the internal components and layout of the distribution cabinet are not easy to change after manufacturing, this limits the flexibility and expandability of the distribution cabinet. Utility Model Content

[0004] Based on the above-mentioned technical problems, this utility model proposes a modular combined low-voltage distribution cabinet.

[0005] A modular low-voltage distribution cabinet includes: a single distribution cabinet unit, two of which can be arranged side-by-side; a heat dissipation vent on the front side of each distribution cabinet unit; several slots on the side of each distribution cabinet unit, each slot containing a positioning plate; the slots are located near the edge of the side; several locking holes on the outer wall of the slots; and screw holes corresponding to the locking holes on the positioning plate; a slot on the rear wall of each distribution cabinet unit, containing various electrical interfaces; a rear cover on the slot, secured to the slot with bolts and closing the slot opening; and a wire groove on the side of the slot, communicating with the slot.

[0006] Preferably, the distribution cabinet unit has one slot on each of its front and rear sides, top and bottom sides.

[0007] Preferably, the positioning plate is detachably installed in the slot.

[0008] Preferably, the outer side of the wire groove is provided with a groove plate, the groove plate can be opened on one side, the upper end of the groove plate is hinged to the wire groove, and its lower end is fastened to the wire groove.

[0009] Preferably, the four sides of the inner side of the back cover are provided with sealing edges, and the sealing edge located on one side of the wire groove is provided with a notch of the same size as the wire groove.

[0010] Beneficial effects: This distribution cabinet can combine two distribution cabinets side by side by using a positioning plate and a slot pre-installed on the side of the individual distribution cabinet. A slot is set on the rear side of the individual distribution cabinet, and various electrical interfaces are set in the slot. The electrical interfaces can realize the wiring connection between the individual distribution cabinets, and can also realize the external wiring of the individual distribution cabinets.
