N2 - With the rapid development of economy and substantial growth of the scale of power network, the safe operation of power system becomes particularly important. While in field of high voltage, hydraulic operating mechanism gradually plays an important role recently. Thus, monitoring and identifying the most common failures to improve the reliability and stability of operating mechanism are of great significance. In this paper, theoretical analysis is carried out for 252kV hydraulic operating mechanism of high voltage circuit breakers and simulation models are established with the software AMESim and Ansoft. The displacement and velocity of the cylinder are verified by experimental results. Then four faults including pressure fluctuations, variation of oil viscosity, fraction stuck and the addition of air content are simulated. With the characteristics of the velocity curves under different conditions, the fault can be directly identified.
