摘要
针对近几年气体绝缘金属封闭开关设备(gas insulated metal enclosed switchgear and controlgear,GIS)需求量增加,造成了组合电器质量下降,在运行中故障频发,暴露出GIS在变电站设计、设备选型、安装、投运、运行维护等方面存在安全隐患等问题。选取近年吉林省发生的典型GIS常见故障,对故障原因进行详细研究,归纳并分析了故障发生时的异同点,探究了其中的关键影响因素以及规律性原因,并且提出了相应的防范措施,提高了GIS安全运行的稳定性,减小故障对电气设备以及电力系统带来的负面影响。
In recent years,the increasing demand for gas insulated metal enclosed switchgear and controlgear(GIS)has led to a decrease in the quality of composite electrical appliances,frequent faults during operation,and exposed safety hazards in GIS equipment in substation design,equipment selection,installation,operation,and maintenance.Select typical GIS equipment common faults that have occurred in Jilin Province in recent years,conduct a detailed study on the causes of the faults,summarize and analyze the similarities and differences when the faults occur,and explore the key influencing factors and regular reasons.And corresponding preventive measures have been proposed to improve the stability of the safe operation of GIS equipment and reduce the negative impact of faults on electrical equipment and power systems.
