Description

Technical Field

[0001] The utility model relates to the technical field of power bus ducts, in particular to a snap-on power bus duct. Background Art

[0002] Busbar ducts, enclosed metal structures composed of copper and aluminum busbars, are used to distribute high power to various components in distributed systems. They are increasingly replacing wires and cables in indoor low-voltage power transmission trunk projects. In Guangzhou, Guangdong, my country, over 90% of the main lines leading from distribution rooms in buildings with 12 floors or more, or from the main lines to the floors, use busbar ducts. Busbar ducts are required for connections from 630 kVA transformers to distribution cabinets.

[0003] Busbar ducts are characterized by their series-matching, commercial production, compact size, large capacity, short design and construction cycles, easy assembly and disassembly, fire resistance, safety, reliability, and long service life. Busbar ducts are suitable for three-phase four-wire and three-phase five-wire power supply and distribution systems with AC 50Hz, rated voltage 380V, and rated currents from 250A to 6300A.

[0004] At present, the snap-on power bus duct in the existing technology is usually installed by a snap-on structure. During installation, since the bus duct is connected by the snap-on structure, and the bus ducts of different models have different sizes, the snap-on structure cannot be adjusted. When installing different models of bus ducts, snap-ons of different sizes are required, resulting in a waste of resources. There is a problem that the size of the snap-on structure cannot be adjusted. Moreover, during installation, holes must be punched in advance at the installation location, and then the snap-on structure and the bus duct must be installed. During installation, the connection between the snap-on structure and the installation location must be pre-measured so that the snap-on structure can be connected to the connection hole. The operation is complicated, and there is a problem that the snap-on structure cannot be conveniently connected to the installation location. Utility Model Content
