AI Technical Summary
When current is shunted in existing circuits, the specifications of the circuits before and after shunting are the same, which leads to a decrease in the rated current after shunting and an increase in cost.
By designing a current-splitting structure and using a connecting component made of multi-strand wires to connect multiple busbar trunkings, the current-splitting and capacity-changing effects of the line are achieved. The rated current values inside the busbar trunkings are different, thus forming a capacity-changing effect.
This achieves the matching of rated current after line shunting, avoiding the use of variable capacity joints and saving costs.
