Analysis on the velocity characteristic of hydraulic mechanism based on AMESIM
Hydraulic mechanism is a crucial part of circuit breakers. The action of hydraulic mechanism in circuit breaker is different from general hydraulic mechanism for its high speed, short operating time and high pressure. In this paper, the working principle of hydraulic operating mechanism of 550kV SF6 high voltage circuit breaker is introduced. Simulations are carried out with AMESIM, hydraulic simulation software. Experiments are carried out to test the pressure, displacement and velocity of hydraulic system. The opening velocity characteristic of the hydraulic mechanism was discussed with the consideration of the influence of the geometry and environmental parameters such as cylinder parameters, pipeline pressure loss, ambient temperature and system pressure.
