主变压器夹件接地电流过大案例分析与处理
Analysis and Treatment of Grounding Overcurrent in Clamps of Transformer
-
摘要: 针对某变电站在正常运行时主变压器夹件接地电流过大的现象,通过带电检测、停电钻芯检查排查故障点,分析故障原因并对故障进行处理,对主变压器的安装、验收、检测工作提出建议。Abstract: Aiming at the phenomenon that the ground current of the main transformer clamp is too large during the normal operation of a substation, the fault points are found through the live detection and the outage drilling inspection, the fault causes are analyzed and the fault is dealt with, and suggestions are put forward for the installation, acceptance and detection of the main transformer.
