AI Technical Summary

Technical Problem

In the existing technology, during the secondary wiring process of combined current transformers, multiple wires are prone to loosening of terminal connections due to pulling, and the tape fixing is prone to aging and failure. The operation is cumbersome and not easy to disassemble, which affects the metering and protection functions.

Method used

Multiple wires are secured using binding straps and a locking mechanism. Quick binding and loosening are achieved through a rotary knob and ratchet mechanism, preventing tape aging and providing a convenient way to adjust the wires.

Benefits of technology

This ensures that the wires are securely fixed regardless of temperature and humidity, simplifies subsequent operations, improves wiring reliability and maintenance convenience, and prevents wires from becoming loose and signal distortion.
