AI Technical Summary
The existing busbar trunking terminal capping method requires complex bolt tightening operations, and subsequent line extensions require extensive disassembly and reinstallation, increasing construction costs and difficulty.
Design a busbar trunking terminal end cap assembly, including an end cap shell and an insulating plate assembly. The split structure of the end cap shell facilitates connection, and the insulating plate assembly forms a barrier between conductors, simplifying end cap operation and facilitating line extension without changing the busbar trunking structure.
It enables quick and convenient capping of busbar trunking terminals, reduces the difficulty and cost of modification, improves modification efficiency, and ensures the safety and reliability of the power system.
