Abstract: In order to solve the problems of difficult operation, long time consumption, and easy displacement during the disassembly and assembly of transformer wiring blocks, this paper designs a new type of wiring block positioning and disassembly tool. The tool uses reference holes and matching bolts to securely connect the copper busbar. Screws are adjusted to align the copper busbar with the wiring port to the same horizontal height. A lever is used to precisely align the copper busbar with the hole position, enabling smooth loading and unloading of wiring screws. This design significantly enhances the safety, convenience, efficiency, and cost-effectiveness of wiring block disassembly and assembly operations.
