一起变电站220kV开关油泵长时间打压无异常信号的分析与处理

Analysis and Treatment of Non-abnormal Signal of Long Time Pressure for 220kV Switch Oil Pump of a Substation

本文针对变电站开关油泵打压超时等异常进行分析与总结。本文对某变电站使用的西门子3AQ1系列开关,在变电运行的过程中,经常出现的“打压超时”信号进行针对性研究;着重从220kV变电站某开关长时间打压无异常信号的运行实践案例分析,结合西门子3AQ1型开关说明书和图纸资料,根据开关实际运行情况,探讨开关在运行过程中,当出现此信号时,如何能快速、安全查找此类故障的方法。并分析了运行过程中存在的问题并给出了管理提升措施,最后对开关在油泵打压超时无异常信号时的处理等相关措施进行了相应总结。

The carries out analysis and summary to switch oil pump pressure time over abnormality etc.for the substation.Simenz 3AQI series switch used in certain substation of ten happens to“pressure time over”sianal during the transformer station is discussed.Emphasize the actual case analysis from non-abnormal signal of long time pressure of certain switch for 220kV substation.Combining simenz type 3AQI switch manual and drawing data and actual aperation conditions of the switch discuss when the signal appenrs during the course of the switch operation how to quickly and safely find out such fault method.Analyze the problems during the course of operation and give management and improving measures.Finally,carry out relevant summary to treatment and relevant measures of the non-abnormal signal of the switch oil pump pressure time over.
