Description

Technical Field

[0001] The utility model relates to the technical field of switch cabinets, in particular to a switch cabinet with a busbar room shared by multiple switch cabinets. Background Art

[0002] The external line of the switch cabinet first enters the main control switch in the cabinet, and then enters the sub-control switch. Each branch is set according to its needs. Such as instruments, automatic control, motor magnetic switches, various AC contactors, etc. Some also have high-voltage and low-voltage room switch cabinets, with high-voltage busbars, such as power plants, etc. Some also have low-frequency load shedding to protect the main equipment;

[0003] In the existing switch cabinets that share a busbar room, multiple lines are arranged without being arranged. They are directly fixed on the wire ducts in the cabinet, which can easily cause line confusion and difficulty in distinguishing the lines. There is a lack of arrangement and combination of lines, and this method is not conducive to pulling the lines. The line connection cannot meet the bending connection in multiple directions.
