At present,there are fewer and fewer exploitable resources in the world,and there are many wind turbine manufacturers in China.A number of domestic enterprises through technology import,digestion and absorption,joint design and independent R&D,wind turbine power has been expanding year by year,multi-megawatt wind turbine r&D process is accelerating.Wind turbine design is more intelligent and subdivided,developed a number of customized units for different environmental and climatic conditions.Although the domestic wind power industry started late,but the rapid development of wind power technology,the construction of wind farms is also expanding.The normal operation of wind farm cannot be separated from the stable operation of primary and secondary equipment,in order to ensure the safety and stability of the power system,fast and reliable removal of faults,as a kind of high-voltage switch,Sulfur hexafluoride circuit breaker has the function of control and protection.These breakers offer excellent arc-extinguishing and insulation performance,and they operate reliably in wind farm applications with convenient operation.However,when the wind farm is handling the circuit breaker fault for opening operation,the circuit breaker jump will lead to the accident and may enlarge the fault,causing equipment and personal harm.In this paper,the problem of jump-type opening and closing of the Sulfur hexafluoride circuit breaker mechanism of wind farm is analyzed,and effective anti-jumping measures are proposed to ensure the safety and reliability of the system operation of the wind farm step-up station.
