Diagnosis Method for Disconnector Opening Fault in Composite Apparatus
The traditional disconnector opening fault diagnosis method directly constructs the diagnosis model,but does not extract the characteristic value of the opening current,causing poor diagnostic effect.Therefore,this paper proposes a diagnosis method for disconnector opening fault in composite apparatus.Firstly,the characteristic value of the opening current is extracted to reduce the complexity of the subsequent model construction.Then,a diagnosis model of disconnector opening fault is constructed,and the corresponding fault diagnosis flow chart is designed.The model is used to realize the diagnosis of disconnector opening fault in composite apparatus.The experimental results show that,the proposed method has a better effect on the diagnosis of disconnector opening fault and is more suitable for practical application.
