AI Technical Summary
In existing dense busbar trunking connection structures, the clamping force of the connecting copper plates far from the central torque bolt is insufficient, resulting in poor contact and high connection resistance, which affects power transmission efficiency and poses safety hazards.
A novel connection structure is designed, which uses a combination of reinforcing slots in the outer side plate and conductive copper busbar, corrugated connecting copper sheet, clamp, insulating partition tube and torque bolt. The clamp, strip groove and insulating phase block are pressed together by tightening multiple torque bolts, which increases the contact area between the corrugated connecting copper sheet and the conductive copper busbar.
This effectively avoids problems such as poor contact and high connection resistance, improving the safety and reliability of power transmission.
