[0013] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0014] Reference Figures 1 to 3 A low-voltage switch cabinet includes a cabinet body 10, and also includes a plurality of busbar clamps 2, fixing columns 3, bolts 4 and a supporting device, the supporting device includes a bracket 5 and a flip bracket 6, the busbar clamps 2 are arranged on the bracket 5 and the flip bracket 6, and both are arranged in the cabinet body 10, the busbar clamps 2 are provided with a plurality of slots 201, and a plurality of fixing columns 3 are arranged between two busbar clamps 2 and connected and fixed by a plurality of bolts 4. In the utility model, when installing the copper bar, a heat shrink tube is installed at the end of the copper bar, the bracket 5 and the flip bracket 6 are first installed in the cabinet body 10, and then a busbar clamp 2 is installed on the bracket 5 and the flip bracket 6, the end of the copper bar cooperates with the slot 201, and another busbar clamp 2 is covered, and the bolt 4 passes through the upper busbar clamp 2, the fixing column 3 and the lower busbar clamp 2 at one time to fix the end of the copper bar between the two busbar clamps 2. Specifically, the fixing column 3, bolt 4, bracket 5 and flip bracket 6 are all made of stainless steel. The surface of stainless steel is relatively smooth and has low viscosity. When the fluid flows on its surface, the friction force is small, which effectively reduces the eddy current effect caused by the large main busbar current. Specifically, a slot is provided on the busbar clamp 2, and one end of the fixing column 3 cooperates with the slot.

[0015] As a preferred embodiment of the utility model, it may also have the following additional technical features:

[0016] In this embodiment, a plurality of cross beams 101 are disposed in the cabinet body 10 , which abut against the top cover of the cabinet body 10 to support the top cover, thereby increasing the strength of the cabinet body 10 .

[0017] In this embodiment, the supporting device also includes a rear insulator mounting beam 7, which is arranged in the cabinet 10. A plurality of plug rods are provided on the insulator mounting beam 7, and a circular hole is provided on the copper busbar. The plug rods on the insulator mounting beam 7 are inserted into the circular hole to provide auxiliary support for the copper busbar.

[0018] In this embodiment, a rear sealing plate 8 is also included, and is arranged in the cabinet body 10 and on one side of the copper busbar. This prevents a person from opening the cabinet door in front of the cabinet and reaching his hand behind the copper busbar to get an electric shock. Specifically, the crossbeam 101, the fixing column 3, the bolt 4, the bracket 5, the rack bracket 6 and the sealing plate 8 are all made of stainless steel. The surface of stainless steel is relatively smooth and has low viscosity. When the fluid flows on its surface, the friction force is small, which effectively reduces the eddy current effect caused by the large current of the main busbar.

[0019] It should be noted that the terms "include", "comprises" or any other variations thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, an element defined by the sentence "comprises a ..." does not exclude the existence of other identical elements in the process, method, article or device including the element.

[0020] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
