AI Technical Summary
Technical Problem
Traditional transport equipment cannot guarantee the stability of the operating speed when transporting DC circuit breakers, which can lead to shaking or damage.
Method used
A chassis for a 1.5kV DC circuit breaker was designed, equipped with a speed sensor, drive assembly, and energy recovery assembly. By monitoring and adjusting the output power of the drive assembly in real time, combined with energy recovery, a constant speed is maintained, and the driving direction is adjusted by a rotating shaft and push-pull rod.
Benefits of technology
It enables stable and safe transportation of DC circuit breakers under different terrain and load conditions, improves transportation efficiency, and reduces safety hazards caused by speed fluctuations.
