Description

Technical Field

[0001] The utility model relates to the technical field of fire-resistant bus ducts, in particular to a fire-resistant bus duct based on a staggered structure. Background Art

[0002] Fire-resistant bus duct is a closed metal device composed of copper and aluminum busbars. It is used to distribute high power to various components of the distributed system. It has increasingly replaced wires in indoor low-voltage power transmission trunk line projects.

[0003] According to a power cable recovery device disclosed on the patent website (authorization announcement CN 218549446U), it is described that "a power cable recovery device includes a first bus duct, a second bus duct, a connection assembly and a protection mechanism; the second bus duct is arranged outside the first bus duct and corresponds to the first bus duct, the connection assembly is installed between the first bus duct and the second bus duct, and the protection mechanism is sleeved on the outside of the connection assembly and located at the outer ends of the first bus duct and the second bus duct."

[0004] In view of the above description, the applicant believes that there are the following problems:

[0005] During use of the utility model, the device is connected to the No. 1 bus duct and the No. 2 bus duct through a connecting component, and then the connecting component is further wrapped by an external protective mechanism, thereby improving the fire resistance and sealing of the overall bus duct. However, in actual use, since the protective mechanism does not adopt a staggered structure at the connection when wrapping the connecting component, it is easy to cause poor protection of the connection. In addition, the device is connected in blocks through multiple areas, which is easy to cause poor overall firmness of the device, and the internal deformation is caused by springs, which is easy to cause damage to internal equipment. In addition, the device completes the connection between the toilets through bolts, which is inconvenient for subsequent disassembly and maintenance. Therefore, it is necessary to improve a fire-resistant bus duct based on a staggered structure. Utility Model Content
