Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of switch cabinets, in particular to a low-voltage drawable switch cabinet. Background Art
[0002] Low-voltage withdrawable switchgear is widely used in low-voltage power supply systems to complete the work of power control, protection, conversion and distribution. The low-voltage withdrawable switchgear is mainly composed of a cabinet body and equipment installation drawers. The equipment installation drawers are generally installed in multiple layers.
[0003] After searching, it was found that the publication number is CN219843347U, and the name is a low-voltage withdrawable switch cabinet. The application proposed a document number CN218732736U, and the name is a low-voltage withdrawable switch cabinet. The drawers of each layer of the cabinet cannot be fully withdrawn. Once fully withdrawn, they are prone to fall and affect the power supply safety. When a fault occurs and needs to be repaired, the drawer cabinet that cannot be fully withdrawn will affect the maintenance work. By adding the embedded components on both sides of the drawer box, when the drawer box is fully pulled out, the embedded components and the cabinet shell are used. The locking is completed, thereby improving the stability of the drawer box when it is fully pulled out, thereby significantly improving the stability of the low-voltage withdrawable switch cabinet during maintenance. However, when using this application, it is necessary to frequently pull out and plug in the fixing pins, which is more troublesome, and the drawer box is difficult to take out and replace. At the same time, it is also necessary to open a limit groove through the outer surface of the cabinet shell. The limit groove is very easy to invade moisture and dust, affecting the use of internal electronic components. At the same time, the exposed first positioning plate and second positioning plate also affect the simplicity of the facade. When the cabinet shells are placed side by side, more installation space is occupied, and further improvements can be made.
