Typical Failure Analysis of SSB Variable Pitch System of GE 1.5sle Unit in a Wind Farm

某风场GE 1.5 sle机组SSB变桨系统发生的故障非常典型,一是故障代码比较笼统,二是故障位置非常隐蔽,三是故障类型和原因比较少见。文章简单描述了设备结构,并对故障现象和处理过程进行了介绍,对故障点和形成原因进行分析,最后对整个故障情况原因进行了总结。

The failure of the SSB variable pitch system of GE 1.5sle unit in a wind farm is quite typical. First is that the failure path code is not specific;second is the location of failure is concealed;third is that the fauh type and cause is quite rare. This paper briefly introduced the equipment structure, symptom of failure and treatment process. It also analyzed the fault location and causes. Finally, the causes of the failure were summarized.
