Research on Non-homogeneous Criterion for the Opening and Closing Positions of Disconnectors Based on Remote Regular Inspection
摘要
To meet the needs of optimizing the regular inspection strategy of power equipment and fully programmed remote control operation of disconnectors, this paper proposes a non-homologous method for the opening and closing positions of disconnectors that can be used in the “remote regular inspection” strategy. This paper decomposes the closing process of the disconnector into two stages, namely the movement stage and the deformation stage. In the movement stage, based on the magnetically coupled resonant wireless power transmission system, this paper established a mathematical model for impedance identification of the disconnector’s opening and closing positions and analyzed the mapping relationship between the spatial position of the disconnector’s movable contact and the system’s reflected impedance. In the deformation stage, this paper establishes a passive Micro-Electro-Mechanical System (MEMS) for sensing the pressure deformation of the movable contact of the disconnector and analyzes the mapping relationship between the deformation degree of the movable contact and the reflected impedance. The results of the above research have important research and guiding value for the application of subsequent remote regular inspection strategies for power equipment.
