| Abstract: |
| The auto-reclosure is one of the important means for the reliability and stability of the power network . When the auto-reclosure cannot cooperate with the circuit breaker, accidents will happen. Through detailing the maloperation process of the circuit breaker because of the defect in the auto-reclosure, this paper analyses the course of the accident and improves the defective protections circuit .The proposed method effectively solves the problem of the auto-reclosure maloperation and improve the stability of device operation. |
| Key words: auto-reclosure maloperation reason analysis |
