AI Technical Summary
Traditional ring main units have large opening and closing torques, low positioning accuracy, and pose safety hazards, making them difficult to popularize in old power grids.
The design employs rollers and elastic plates to generate tactile feedback. The drive disk and positioning groove are driven by a rotating shaft. The collision between the rollers and the positioning groove generates tactile feedback, reducing the operating torque and confirming that the position is in place. At the same time, the worm gear mechanism enables adjustable preload, and the combination of magnetic blocks and a visible red and green dial improves safety.
It reduces operating torque, improves operational safety and convenience, enhances positioning accuracy, and is suitable for the renovation of old power grids.
