AI Technical Summary
Existing current transformer installation structures suffer from problems such as large size, susceptibility to damage, and difficulty in adapting to different installation scenarios during transportation and installation.
The structure employs a retractable mounting plate and telescopic groove, combined with a spring assembly and retaining plate design, to achieve self-adjustment and limiting of the mounting plate. Stability is ensured through guide grooves and bolt connections.
Reduce volume during transportation, lower the risk of damage, improve installation adaptability and efficiency, simplify installation operations, and enhance structural stability.
