Description

Technical Field

[0001] The utility model relates to the technical field of low-voltage power distribution cabinets, and more specifically, to a busbar supporting device of a low-voltage power distribution cabinet. Background Art

[0002] The distribution cabinet (box) is divided into power distribution cabinet (box), lighting distribution cabinet (box) and metering cabinet (box). It is the final equipment of the distribution system. The distribution cabinet is a general term for the motor control center. 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, lighting and distribution of power conversion and control. There is a large bus in the low-voltage distribution cabinet.

[0003] A plurality of wire threading troughs are arranged on the side of the existing low-voltage distribution cabinet. The busbars of the distribution equipment inside the low-voltage distribution cabinet pass through the wire threading troughs, while ensuring the orderly arrangement of the busbars inside the low-voltage distribution cabinet. A structure for supporting and fixing the busbars is installed inside the low-voltage distribution cabinet. However, there is a lack of structure for supporting and fixing the busbars outside the low-voltage distribution cabinet. During use or during the laying of the busbars, the external busbars will shake, and the busbars will rub against the sides of the wire threading troughs. The external protective layer of the busbars is easily worn, resulting in the risk of leakage. In addition, some existing distribution cabinets are installed outdoors. When it rains, rainwater will flow into the interior of the cabinet through the wire threading troughs. Utility Model Content
