摘要
在某些情况下,由于气体绝缘金属封闭开关设备(GIS)汇控柜交流电源监控回路设计不当,会造成监控存在盲区。以宁波电业局500 kV句章变电站GIS汇控柜交流电源发生的异常情况为例,分析了GIS汇控柜交流电源监控回路发生异常情况的原因以及造成的影响,提出了针对GIS汇控柜交流电源告警回路的改进方案。该方案在现场实施后,效果良好。
In some cases, monitoring exists blind area because of the unsuitable design in monitoring circuit for AC power supply of GIS control cabinet. Taking 500 kV AC power supply fault in control cabinet of Juzhang substation in Ningbo Power Supply Bureau for example, the reasons and influence of the fault in monitoring circuit are analyzed. Improvement methods are also proposed and application in site shows effective.
