AI Technical Summary

Technical Problem

In existing technologies, grounding carbon brushes are prone to poor contact due to excessive wear after prolonged use, which affects the stable operation of the generator.

Method used

A generator grounding carbon fixing bracket was designed, including a grounding ring, a positioning plate, a U-shaped frame, a brush box, a carbon brush body, a spring, an end cap, an insulating rod, and a detection device. The fixing bracket structure is formed by the positioning plate and the U-shaped frame, and the carbon brush body is in effective contact with the grounding ring. The spring ensures that the carbon brush body can still abut against the grounding ring after wear. The detection device monitors and alarms in real time to ensure good contact.

Benefits of technology

It effectively prevents poor contact caused by wear of the grounding carbon brush, ensures that the shaft current is smoothly conducted to the ground, avoids equipment accidents, and improves the stability and reliability of the generator.
