| Abstract: | The working principle of hydraulic mechanism for high voltage circuit breaker is introduced,and the source of air contamination in hydraulic system is analyzed.The harms of the air contamination to the circuit breaker are emphatically discussed,including oil leakage,unstable action time,and cavitation.Moreover,the methods for preventing air contamination are proposed,such as avoiding the air retention through improvement of structure design and whole layout,and exhausting the air by vacuum pump or exhaust v... |
