    摘 要 :有载滤油机低在线率往往是造成变压器有载分接开关故障的重要原因。对有载滤油机的在线率过低的问题进行了研究,分析出缺乏相关信号电缆、远动信号点和滤油机故障是导致主变滤油机低在线率的具体原因,结合工程实际,通过敷设有载调压机构箱与有载滤油机之间的联络电缆,及增加主变滤油机相关远动信号点后,有效提高了主变有载滤油机在线率。并对滤油机在线情况进行分析,及时发现滤油机本身故障,保证了有载调压变压器的安全运行。

    Abstract: The low online rate of the onload oil filter is often an important reason for the failure of the on-load tap changer of the transformer. The problem of low online rate of the on-load oil filter was studied, and it was analyzed that the lack of relevant signal cables, remote signal points and the failure of the oil filter were the specific reasons that led to the low online rate of the main transformer oil filter. Combining with the actual project, by laying the connection cable between the load regulator box and the on-load oil filter unit, and adding the remote signal points of the main transformer oil filter unit, the online rate of the main transformer on-load oil filter unit is effectively improved.The online condition of the oil filter is analyzed, and the fault of the oil filter itself is found in time to ensure the safe operation of the on-load voltage regulating transformer.
    Key words: power transformer; on-load oil filter; online rate; monitoring signal
