AI Technical Summary

Technical Problem

The existing high-voltage vacuum circuit breaker transfer trolley relies on manual brakes, which poses a risk of micro-motion due to mechanical clearance or hydraulic leakage, resulting in insufficient stability and a high risk of safety accidents. Furthermore, maintenance requires on-site disassembly and assembly of a large number of cables and components, making the operation cumbersome and time-consuming.

Method used

It adopts a design that integrates lidar, sensors, PLC control modules, and modular integrated boxes to achieve intelligent navigation and obstacle avoidance, and provides active mechanical parking locks. The modular integrated boxes can be quickly disassembled and assembled, simplifying the maintenance process.

Benefits of technology

It significantly reduces the risk of human error and collisions, improves the stability of the trolley during handling and maintenance, shortens maintenance time, and increases equipment availability.
