摘要
根据一起串补MOV内部故障引起的跳闸,对保护动作行为进行了分析。结合保护动作、录波数据分析,确定火花间隙并未真正点火触发。通过分析串补设备特殊安装方式可知,GAP内电流互感器的电流并不是GAP点火导通后电流。最后,提出了改进措施和应注意的问题。
According to a trip event caused by MOV internal fault of series compensation,the action of the protection is analyzed. Based on the analysis of protection action, recorder data, it is confirmed that the spark gap is not fired triggered successfully. By analyzing the special installation mode of series compensation, it is found that the current of CT in the GAP is not the current of GAP after conduction. Finally, improvement measures and notes are proposed.
