Sf6 high-voltage circuit breaker contact status detection at different currents

HIGHLIGHTS

  • who: Ze Guo and colleagues from the State Key Laboratory of Reliability and Intelligence of Electrical Equipment, Hebei University of Technology, Tianjin, China have published the paper: SF6 High-Voltage Circuit Breaker Contact Status Detection at Different Currents, in the Journal: Sensors 2022, 8490 of /2022/
  • what: In this paper, a feature extraction method based on frequency is proposed, a recognition model composed of a DNN and BO is constructed, and an NDT for the contact state of the SF6 HVCB is proposed. It can be observed that the vibration signal was a stationary signal . . .
