[0036] Each of the unit conductive elements 3 is connected to one of the unit conductive rings 2. Each unit conductive element 3 includes an input terminal 301 and a conductive device 302 connected in sequence. The conductive device 302 is rotatably connected to the outside of one of the unit conductive rings 2 and is electrically connected to that unit conductive ring 2.

The unit conductive elements 3 and the unit conductive rings 2 together form the unit bus ring to realize the modularity of the rolling bus ring device, so that the user can adjust the maximum rated value of power transmission of the rolling bus ring device suitable for power transmission.

[0037] In use, the user first needs to attach the unit conductive ring 2 onto the mounting shaft 1 and align the output end 201 with the input port 101. The output end 201 is connected to a wire, which connects to the power supply equipment or the power consumption equipment along the input port 101-the mounting shaft 1-output port 102.

The number of unit conductive elements 3 varies with the number of unit conductive rings 2. The unit conductive elements 3 and the unit conductive rings 2 together form the unit bus ring to realize the modularity of the rolling bus ring device, so that the user can adjust the maximum rated value of power transmission of the rolling bus ring device suitable for power transmission.
