摘要
对一起典型的220 kV线路档中风偏跳闸故障进行了分析计算和原因剖析,指出线路档中最大风偏不满足规程要求是引起故障的主要原因。提出了一种档中导线风偏值的简易估算公式,为一线运行人员及时判定档中风偏是否存在问题提供了一种可行的方法。
A typical 220 kV line trip caused by wind deviation is calculated and analyzed in this paper.It is indicated that the maximum wind deviation can not meet requirements of the specification,which is the main reason of the fault.The paper proposes a simple formula for wind deviation estimation,which provides a feasible way to the operation personnel to timely determine if there are problems in wind deviation.
