故障树分析法在电力变压器故障分析中的应用

Application of Fault Tree Analysis in Power Transformer Fault Analysis

通过对电力变压器常见故障类型进行介绍,包括绕线圈故障、铁芯故障、分接开关故障、套管故障、绝缘故障、密封不良等,分析了其故障原因和危害,并利用故障树分析原理构建电力变压器故障树。分析认为,及时巡查和维护电力变压器,确保设备处于稳定工作状态是避免故障发生最为有效的方法。

By analyzing the common fault types of power transformer, including winding coil fault, iron core fault, tap switch fault, casing fault, insulation fault, poor sealing and so on, the cause and harm of the fault are analyzed, and the fault tree of power transformer is constructed by using the principle of fault tree analysis. It is considered that it is the most effective method to inspect and maintain power transformers in time to ensure that the equipment is in a stable working state.
