Description

Technical Field

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

[0002] The door of a low-voltage electrical cabinet refers to the door installed on the box of a low-voltage electrical switchgear. The door of a low-voltage electrical cabinet is usually made of metal materials, such as steel plates or aluminum alloys, to ensure that it has sufficient strength and corrosion resistance.

[0003] At present, most low-voltage electrical cabinet doors are processed by overall bending and partial welding. Although this operation can also be used to make electrical cabinet doors, the strength of this type of electrical cabinet doors is relatively poor. Because each piece of steel is subjected to different stresses during welding, processing defects such as welding deformation are caused, which greatly reduces the product quality. In order to improve the strength, this application uses 1.5 or 2.0 strength steel as raw material, and the strength of the door panel has been greatly improved. On the basis of meeting customer needs, the product cost is reduced, and there is no welding in the processing process, which avoids welding defects and avoids shortcomings such as poor dimensional accuracy and poor appearance quality caused by welding.
