As an important switch device in the power system,the accurate determination of the status of the disconnector is crucial for the operation and maintenance of the power system.Therefore,this paper proposes a method for recognizing the status of disconnectors in the power system based on a multi-source laser architecture.Firstly,a fixed-position multi-channel laser ranging architecture is employed to measure the distance of the contact point during the opening and closing of the disconnector parallelly.Secondly,the measured data is processed to form criteria for determining the opening and closing status of the disconnector,which is then converted into electrical signals and integrated into the electric circuit of the control cabinet.Ultimately,real-time monitoring and identification of the disconnector status is achieved.Field experiments demonstrate that the designed multi-channel laser ranging architecture enables simultaneous distance measurements in multiple channels,thereby improving measurement efficiency and accuracy.Moreover,this architecture can promptly identify abnormal states and take corresponding control measures to ensure the reliable operation of the power system.The proposed method for disconnector status recognition in this paper effectively enhances the safety and stability of the power system,demonstrating significant practical significance and application value for real-time monitoring and control of disconnector status.
