AI Technical Summary
When installing and maintaining existing high-voltage DC contactors in confined spaces, it is difficult to flexibly adjust the angle, and the disassembly and installation process is complicated, requiring each fastener to be tightened individually.
A DC contactor including an angle adjustment component and a quick-release component was designed. The angle adjustment component enables flexible angle adjustment, and the quick-release component enables rapid assembly and disassembly, simplifying the operation process.
Precise angle adjustment and quick assembly/disassembly of DC contactors were achieved in confined spaces, improving maintenance efficiency and simplifying the installation process.
