摘　　要：目前全球可开发利用的资源越来越少,而全国风电机组生产制造厂商却越来越多,生产规模较之前不断扩大。国内一批企业通过技术引进、消化吸收、联合设计以及自主研发等方式,使风电机组功率呈现逐年扩大之势,多兆瓦级风电机组的研发进程正在加快。制造厂商在风电机组设计方面更加智能化和细分化,研发出了很多适合不同环境气候条件的定制化机组。国内风电行业虽然起步较晚,但风力发电技术迅猛发展,风电场的建设规模也在不断扩大。SF6断路器作为发电送出线路及主变压器等设备中的一种高压开关,具有控制和保护作用。它不仅具有较突出的灭弧和绝缘性能,而且在风电场实际应用中性能相对稳定,操作也非常方便。然而,风电场在处理断路器故障进行分闸操作时,断路器的跳跃将会导致事故发生并可能扩大故障,造成设备及人身危害。本文对风电场LW8-40.5六氟化硫断路器机构的跳跃式分合闸问题进行了分析,并提出了有效的防跳措施,保证了风电场升压站系统运行的安全可靠性。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 stepup station.
