Description

Technical Field

[0001] The utility model relates to the technical field of electrical cabinets, in particular to an assembled low-voltage electrical cabinet. Background Technique

[0002] A low-voltage electrical cabinet refers to an electrical device used in a low-voltage power distribution system, usually located at the final control point of the low-voltage power distribution system. The low-voltage electrical cabinet mainly undertakes functions such as low-voltage power distribution, control, protection, measurement, and signal transmission, and is a key bridge connecting the high-voltage power grid and terminal equipment. In the prior art, in order to facilitate the transportation of the electrical cabinet, the electrical cabinet will be assembled after the transportation is completed. At present, after the existing assembled low-voltage electrical cabinet is assembled and used, the connection structure for assembling the electrical cabinet is arranged on the outside of the electrical cabinet. Thieves disassemble it from the outside of the electrical cabinet and then steal or damage the internal components of the low-voltage electrical cabinet, resulting in poor safety performance.

[0003] After retrieval, a prior art provides an assembled low-voltage electrical cabinet (publication number: CN207052956U). The utility model includes a bottom plate, a back plate, and a top plate. Assembly grooves are opened on both sides of the upper end of the bottom plate. The assembly grooves are connected to side plates through assembly sliders. Assembly holes are opened at the rear end and the top end of the side plates. A sliding plug is arranged in the assembly holes. A sliding column is connected to the side of the sliding plug. A spring is sleeved on the sliding column. The other end of the sliding column is rotatably connected to a pull ring. A cover is arranged at the orifice of the assembly hole. Groove holes are opened on the plate surfaces of the back plate and the top plate. Accommodating grooves are opened on one side plate surface of the back plate and the top plate. The sliding column located at the rear end of the side plate is connected to the back plate through the groove hole, and the sliding column located at the top end of the side plate is connected to the top plate through the groove hole. A cabinet door is arranged at the front end of the side plate, and a handle is arranged on the cabinet door. Compared with the prior art, this utility model adopts this connection method, which is convenient for the assembly and disassembly of the electrical cabinet, easy to use, and beneficial to the transportation of the electrical cabinet, and is very suitable for electrical equipment that needs to be frequently relocated.

[0004] The above-mentioned assembled low-voltage electrical cabinet has the problem of poor safety performance. For example, the connection structure for assembling the low-voltage electrical cabinet is arranged on the outside of the electrical cabinet.
