High-voltage circuit breaker is an important protection and control device in power system, its working state affects the safe operation of the system directly. The working principle and energy distribution principle of high-voltage circuit breaker are analyzed,then a mathematical model of energy distribution for high voltage circuit breaker is established. A dynamic model of spring mechanism for high voltage circuit breaker is established,dynamic simulation is carried out according to the actual working condition of the high voltage circuit breaker. In order to obtain the low of motion parameters of high voltage circuit breaker,fully analyzed the failure of single fault of closing spring,opening spring,damper,parts loosening and jam faults.
