Structural Design and Performance Optimization of Electric Double-Ended Socket Wrench for 10 kV Uninterrupted Operation

To address the problems of low bolt-tightening efficiency, difficult alignment, and high labor intensity in 10 kV distribution network uninterrupted operation, this study proposes an integrated solution based on an electric double-ended socket operating rod. Based on a modular structural design, this study establishes a system consisting of a driving handle, an insulating rod, and a double-ended working head. Finite element simulation is employed to optimize the electric field distribution of the insulating structure and to achieve a lightweight design of the transmission components. The developed prototype passes the 45 kV/1 min power-frequency withstand voltage test. Its leakage current remains below 10 μA, the consistency deviation of the double-ended torque output is less than 8%, and the total mass is reduced to 3.2 kg. Field application results show that it increases the replacement efficiency of parallel groove clamps by more than 60%. It also significantly improves operational safety and the level of intelligent operation.
