Abstract :
The optimum design method of moving characteristics of 126kV Vacuum Circuit Breaker (VCB) with spring operation mechanism is presented in this paper. Mathematical model and virtual prototype of 126kV VCR arc set up, and the dynamic and kinetic characteristics arc described as well. ADAMS (Automatic Dynamic Analysis of Mechanical System) is applied in the dynamic simulation to solve the complex calculation of moving characteristics. Satisfactory simulation results can be obtained by iterative modifying parameters of the model, and it is shown that this model can be used to study the dynamic features of VCB and to provide a good basis for circuit breaker optimum design.
