塔河油田变频器故障处理及效果分析

频繁停机会造成电泵机组绝缘等级下降,降低机组运行寿命,为此,开展了变频器故障分类统计,主要分为过热停机、误报停机及直流欠压停机。结合现场情况对变频器故障原因进行了分析,并提出改善措施。通过合理改善变频器工作环境,制订相应管理制度,变频器故障发生率较前期下降132井次,降低幅度57.6%,同时为进一步降低变频器故障发生率,提高变频器对塔河油田工区的适应性,提出下步改进计划及措施。

Fault Processing of Inverter and Result Analysis in Tahe Oilfield

Frequent stopping can cause the loss of ESP insulation and reduce the running life, therefore, inverter fault classification statistic is carried out, mainly divided into overheating stopping, misinformation stopping and DC voltage stopping, inverter fault is analyzed combined with field condition and improvement measures are put forward. By improving working environment and formulating corresponding management system, inverter fault rates down 132 and the reduced rate is 57.6%, in order to further reduce inverter fault at the same time and improve inverter on the suitability in tahe oilfield, the improvement plan and measures are put forward.
