Abstract
The mechanical properties of the transmission system have a great influence on the operation stability of high-speed breaking circuit breakers. This paper designs a 550kV high-speed breaking circuit breaker drive system, establishes a transient dynamics simulation model of the drive system, and compares and analyzes the contact movement characteristics and the force of each component during normal and high-speed opening processes. The research results show that the moving contact displacement and speed simulation results are highly consistent with the experimental test data, and the maximum error does not exceed 5%; the peak stress of each component of the high-speed circuit breaker transmission mechanism is far greater than that of the normal-speed circuit breaker, and the maximum load occurs in the substation The starting time of the brake; the stress peaks of the components of the transmission mechanism of the constant-speed circuit breaker are within the safety margin, and the maximum stress values of the guide rod joint and the crank arm in the transmission mechanism of the highspeed circuit breaker during the entire opening process are respectively 1003.6MPa and 717.44MPa, exceeding the yield strength of the material itself, there is a risk of damage.
