Abstract

To optimize the high voltage circuit breaker transmission system and reduce stress and quality of transmission parts

based on Hypermesh software and Ls-Dyna transient dynamics simulation software

considering the clearance

bar flexible

contact collision and so on

meshing method and the quality control standards are proposed andthe transient dynamic simulation model of a 550 kV circuit breaker transmission system simulation model is established

the closing and opening operation process are simulated. The simulation results show that the maximum stress oftransmission occur in the opening moment of the opening pr

ocess

the pin hole is the maximum stress position

the stressin the rest of the parts is small

which have optimization space. The simulation results are tested and verified

whichindicates that the simulation results are consistent with the measurement results and the maximum relative error ofsimulation is 8.67%. The optimization method of transmission parts is proposed and verified by simulation

whichindicates that the maximum stress of the long connecting rod down from 5.27×10

Pa to 4.13×10

the quality reduced from 11.73 kg to 4.43 kg.
