Optimal Desgn Of Modular Sprng Operating Mechanism Based On ADAMS Simulation Analysis

Modular spring operating mechanism is the dynamic mechanism of the circuit breaker.It supports the open-closing movement and open-closing remain for the circuit breaker.Its mechanical properties,electrical properties and movement process play a key role to protect the power transmission and distribution systems.Under the background of this application,combined with the research and analysis of the existing modular spring operating mechanism,this paper mainly discusses a optimum designed modular spring operating mechanism.On the basis of referring to the related literatures in recent years,this paper studies the structure and performance of the modular spring operating mechanism,designs and analyzes the energy storage motor,transmission ratio,the cam and energy storage spring of the modular spring operating mechanism.Based on the above analysis,the article proposes an optimal design scheme of cam contour and switch stay pawl,and the reasonableness of the optimal design is verified by simulation and experiment.In this paper,a three-dimensional model of modular operation mechanism is established in UG7.0.And the opening speed,closing speed,closing overshoot and optimized design under different parameters is simulated by ADAMS.The simulation results verify the rationality of the optimization design,and obtain more reasonable design parameters and simulation data.Finally,the model machine and the test platform are built,and the mechanical and electrical properties of the model machine are tested.The test results are compared with the simulation data,which indicates that the modular spring operating mechanism meets the design requirements.
