It is the final equipment of the power distribution system and is widely used in power plants, substations, power departments of industrial and mining enterprises and other power users to receive and distribute electric energy.
[0003] At present, the main busbar in the low-voltage distribution cabinet is generally placed on the top or back of the cabinet, and is connected to various cabinets through the whole busbar or spliced through the main busbars between the cabinets. When the main busbar is spliced, usually due to various factors such as space limitations, the entire distribution cabinet top cover needs to be removed on site to splice and fix the main busbar;
[0004] It is found in actual use that the existing low-voltage distribution cabinets have the following deficiencies:
[0005] The top cover plate of the power distribution cabinet is parallel to the top of the power distribution cabinet. At the top, the bolts are screwed into the top cover plate and the cabinet body for installation. When the main bus needs to be assembled and adjusted, it is necessary to use a ladder to screw out the bolts at the top of the cabinet body and then open the top cover plate of the power distribution cabinet, which makes the operation inconvenient;
[0006] In addition, the top cover of the existing power distribution cabinet is in a rectangular plane shape, and the connection seam between the top cover and the cabinet body is exposed to the outside. After disassembly and assembly, the top cover is uneven, resulting in a larger gap, which makes it easy for debris to fall in and cause failures;
[0007] Therefore, the present application provides a low-voltage distribution cabinet to meet the needs. Utility Model Content
