Dual C-type bus bar

Abstract

The invention discloses a bus bar which is used in low-voltage complete equipment, and particularly relates to a dual C-type bus bar. The dual C-type bus bar comprises two C-type bus bar main bodies of which the opening directions are opposite, wherein one back part is shared by the two C-type bus bar main bodies, and the two C-type bus bar main bodies and the back part which is positioned between the two C-type bus bar main bodies are of an integrated structure. By adopting the structure, the two C-type bus bar main bodies and the back part which is positioned between the two C-type bus bar main bodies are of the integrated structure, the back part is shared by the two C-type bus bar main bodies, thus the bus bar installation space is saved by adopting a bus bar system when the current of a power distribution system is larger, the working intensity of a worker is relieved, the installation time is saved, the installation of the bus bar is convenient, and the current carrying ability is enhanced; and meanwhile, a slot at the front side or the rear side can be selected to be connected with a switch or other cabinet bodies when the bus bar is in installation, and the installation of the bus bar can be convenient and flexible.

Description

[0001] technical field [0002] The invention relates to a busbar used in low-voltage complete sets of equipment, in particular to a double C-type busbar. Background technique [0003] The busbar in the low-voltage complete set of equipment is a transmission conductor used to carry current. The traditional busbar adopts a rectangular cross-section, which limits its current-carrying capacity due to the skin effect of the current. In order to improve the influence of the skin effect, there are currently special-shaped busbars with C-shaped cross-sections instead of traditional rectangular-section busbars. When the current is greater than 4000A, the existing busbar installation method is to use two sets of C-shaped cross-section special-shaped busbars to be installed in parallel, and the two sets of rows are connected in rows to ensure the carrying capacity, which requires a large space for installation At the same time increase the labor intensity of workers. In addition...

When the current is greater than 4000A, the existing busbar installation method is to use two sets of C-shaped cross-section special-shaped busbars to be installed in parallel, and the two sets of rows are connected in rows to ensure the carrying capacity, which requires a large space for installation At the same time increase the labor intensity of workers

In addition, the common C-shaped cross-section busbar can only be connected to other components through one side. When the component mounting surfaces at both ends are located on different sides, it will bring difficulties to the installation and limit its use.
