Accurate dynamic simulation of high-voltage disconnectors is the basis for performance optimization,strength checking,fault diagnosis,and maintenance.With the help of ADAMS,the multibody dynamics simulation and torque characteristics of high-voltage disconnectors are studied,and the parametric linkage mechanism and contact contact model are established.The relevant kinetic parameters of the model are set according to theoretical calculations and ANSYS Workbench modal analysis results.Through simulation,dynamic characteristics such as tactile deformation and operating torque of the closing process are obtained.The simulation results are compared with theoretical analysis and measured waveforms to verify the accuracy of the model.Finally,the change of the closing torque of the disconnector under different parameters is analyzed.The proposed multibody dynamics simulation method and analysis results can optimize the design and reduce costs for the disconnector in the design stage,and provide theoretical basis and data support for engineering analysis and operation and maintenance guidance in the engineering application stage.
