[0002] GGD low-voltage distribution cabinets, also known as fixed AC low-voltage distribution cabinets, are mainly used for receiving and distributing power to ensure the safety and reliability of power supply. They are suitable for AC 50Hz power distribution systems in power plants, factories, mines, and other power users, with a rated operating voltage of 400V and a rated operating current up to 3200A. They are used for the conversion, distribution, and control of electrical energy in power, lighting, and distribution equipment. The traditional GGD low-voltage distribution cabinet's frame structure includes four large uprights and large horizontal and vertical beams connecting the ends of the uprights. However, the uprights, horizontal beams, and vertical beams are typically square profiles and fixed with expansion bolts, resulting in poor connection strength and difficulty in disassembly and assembly.

[0004] To solve the above problems, the technical solution adopted by this utility model includes: a cabinet frame and a cabinet door hinged to the outside of the cabinet frame. The cabinet frame includes at least four large columns and a large horizontal beam and a longitudinal beam connected between the two ends of the large columns. The large horizontal beam includes an integrally bent bottom plate, a front side plate, a rear side plate and a top plate. The two ends of the bottom plate are integrally bent to form end plates that can be connected to the large columns and the longitudinal beams at the same time. The end plates are provided with first screw holes at both ends. Washer nuts are embedded in the large columns and longitudinal beams at positions corresponding to the end plates. The end plates and washer nuts are connected and fixed by screws.

[0005] The high-strength GGD low-voltage distribution cabinet is characterized in that: a set of circumferentially arranged positioning protrusions are provided next to the first screw hole on the end plate, and positioning holes that are positioned and matched with the positioning protrusions are provided on the large column, longitudinal beam and washer nut.

[0006] The high-strength GGD low-voltage distribution cabinet is characterized in that: the top plate is bent at both ends to form a reinforcing plate that overlaps with the inner side of the end plate, and the reinforcing plate is provided with a second screw hole that overlaps with the first screw hole.

[0007] The high-strength GGD low-voltage distribution cabinet is characterized in that: angle iron is provided at the angle between the main column and the main crossbeam and longitudinal beam.

[0008] The high-strength GGD low-voltage distribution cabinet is characterized in that: the large column is made of C-shaped material and has a concave surface in the middle of the outer side.

[0009] The high-strength GGD low-voltage distribution cabinet is characterized in that: small columns are connected between the longitudinal beams.

[0010] The high-strength GGD low-voltage distribution cabinet is characterized in that: small crossbeams are connected between the longitudinal beams.

[0011] The high-strength GGD low-voltage distribution cabinet is characterized in that: hinge mounting brackets are provided at both ends of the large column.

[0012] The high-strength GGD low-voltage distribution cabinet is characterized in that the washer-type nut is square.

[0013] The advantages of this high-strength GGD low-voltage distribution cabinet are as follows: Through the improvement of the large crossbeam structure, not only is its own strength better, but the large columns and longitudinal beams are also connected and fixed by the end plates and the washers, nuts and screws, resulting in better connection strength and convenient assembly and disassembly.

[0023] Reference Figure 1-8As shown, the high-strength GGD low-voltage distribution cabinet of this utility model includes a cabinet frame 1 and a cabinet door 3 hinged to the outside of the cabinet frame 1 via hinges 2. The cabinet frame 1 includes four large columns 4 and a large horizontal beam 5 and a longitudinal beam 6 connecting the two ends of the large columns 4. The large horizontal beam 5 includes an integrally bent base plate 7, a front side plate 8, a rear side plate 9, and a top plate 10. The two ends of the base plate 7 are integrally bent to form end plates 11 that can be connected to the large columns 4 and the longitudinal beams 6 simultaneously, and the two ends of the end plates 11 are provided with first screw holes 12. Washer nuts 16 are embedded in the large columns 4 and the longitudinal beams 6 at positions corresponding to the end plates 11, and the end plates 11 and the washer nuts 16 are connected and fixed by screws 17. The washer nuts 16 are usually pre-placed in the large columns 4 and the longitudinal beams 6. The washer nuts 16 are ideally square in structure, so that they can be installed and fixed in the large columns 4 and the longitudinal beams 6 in any direction.

[0024] Preferably, the end plate 11 has a set of circumferentially arranged positioning protrusions 13 next to the first screw hole 12, ideally with four circumferentially arranged positioning protrusions 13 next to each first screw hole 12. The large column 4, longitudinal beam 6, and washer nut 16 are provided with positioning holes 14 that engage with the positioning protrusions 13.
