| Abstract: | The 550 kV high voltage circuit breaker with hydraulic operating mechanism is taken as the investigation subject. The pressure loss in pipe and the pressure wave propagation in the process of opening and closing motion are analyzed. The model of the pressure loss in pipe and the model of the pressure wave distributed parameter are established. Simulation is carried out by using AMEsim software. The influence of the pipe characteristics and structure parameters on the system performance is discussed. The simulation results are thought to be in accordance with the experiment results. It shows that the models are correct. |
