Description

Technical Field

[0001] The utility model belongs to the technical field of power distribution cabinets, in particular to a busbar supporting structure of a low-voltage power distribution cabinet. Background Art

[0002] The busbar of the low-voltage distribution cabinet is a main conductor made of materials with excellent conductive properties such as copper or aluminum. It is not only a channel for electric energy transmission, but also responsible for introducing power from the incoming cabinet and efficiently distributing it to each feeder cabinet or outgoing cabinet, and then flowing to each electrical equipment. It also bears the responsibility of centralized power supply, so that multiple loads can obtain stable and reliable power supply at the same time. In order to make the busbar more stable after installation, a supporting structure is required.

[0003] However, due to different application scenarios, the size of the busbar also varies. The busbar support structure of the existing low-voltage distribution cabinet usually cannot be adjusted according to the busbar size. If the support structure does not match the busbar size, the busbar will become loose under the influence of long-term vibration, resulting in poor contact.

[0004] To this end, we provide a busbar support structure for a low-voltage distribution cabinet to solve the above-mentioned problems. Utility Model Content
