[Abstract]:The transmission mechanism of high voltage circuit breaker has the problems of high load force and complex structure, which is not conducive to the reliability experimental research in the laboratory. In order to study the mechanical reliability of the transmission mechanism of high voltage circuit breaker, the main contact mechanism of the transmission mechanism is studied in this paper, and the equivalent model design of the main contact mechanism of the circuit breaker transmission mechanism is studied by using the similarity theory. This provides a new idea for laboratory to study the reliability of high voltage circuit breaker transmission mechanism and has important engineering application value. The main contents of this paper are as follows: firstly, the kinematics and dynamics of the main contact mechanism are analyzed, and the equivalent design of the main contact mechanism is completed with the mass substitution method. The kinematic and dynamic characteristics of the designed equivalent principal contact mechanism and the original main contact mechanism are compared and analyzed by using ADAMS software. The results show that the designed equivalent principal contact mechanism and the original main contact mechanism are equivalent in dynamic characteristics. Based on the similarity theory, the similarity design of the equivalent main contact mechanism is carried out, and the similarity model of the equivalent main contact mechanism is designed. By using the method of equation analysis and dimensional analysis, the corresponding similarity relations between the prototype of the equivalent principal contact mechanism and the physical quantities of its similar model are obtained. In order to verify the correctness of the similarity relation, the dynamic stress of the connecting rod of the main contact mechanism is analyzed, and the correctness of the similarity relationship between the prototype and the similar model of the equivalent principal contact mechanism is verified by using ADAMS software. By using ADAMS and ANSYS software, the dynamic stress similarity relations of the primary contact mechanism, the prototype of the equivalent main contact mechanism and the similarity model of the equivalent main contact mechanism are obtained. Furthermore, the similarity relationship between the prototype of the equivalent main contact mechanism and its similar model is studied, and the modal similarity relationship between the prototype of the equivalent main contact mechanism and its similar model is obtained, and the simulation results are verified by Workbench software. It is shown that the results of modal similarity analysis are correct. The research in this paper provides the basis for the design and improvement of the experimental model of the transmission mechanism of the high voltage circuit breaker, and is beneficial to the practical application of the engineering.
