Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of power distribution cabinets, and more specifically to a low-voltage power distribution cabinet with a protective function. Background Art
[0002] The rated current of the low-voltage distribution cabinet is AC 50Hz, and the rated voltage of the distribution system is 380V. It is used for power conversion and control of lighting and power distribution. However, the switch controller installed in the low-voltage distribution cabinet needs to occupy a larger space inside the cabinet, which reduces the internal space of the distribution cabinet. The layout of the electrical components of the low-voltage distribution cabinet needs to be adjusted, which reduces its convenience of use. In addition, the connecting wires of the switch controller are relatively scattered after installation and are easy to fall off due to scratches.
[0003] For example, announcement number CN216355389U discloses a low-voltage distribution cabinet with protective function, including a cabinet body, a door body and a switch protection mechanism; the cabinet body is divided into three areas by partitions, namely the first area, the second area and the third area; the third area is located at the lower right corner of the cabinet body, and a switch controller is installed in the third area.
[0004] It can be seen from the above-mentioned public scheme that the frame-type support plate and the switch controller need to occupy the third area inside the cabinet, which greatly reduces the internal space of the cabinet. When installing and arranging the electrical components of the distribution cabinet, the installation and arrangement space is greatly reduced, and multiple arrangement adjustments are required, which reduces the convenience of use. In addition, the switch controller is installed inside the frame-type support plate, so that its connecting wires are scattered inside the frame-type support plate, which can easily scratch the scattered connecting wires when the first cover is opened, and can easily squeeze the scattered connecting wires when the first cover is closed.
