ZF9-252 GIS电气设备在福州电网应用中二次控制回路存在问题及解决方法

Problems and solution of the control circuit of ZF9-252 GIS when applied in Fuzhou power grid

西安西开电气的室外GIS在福州电业局新投产的220kV变电站投入使用,在安装调试过程中发现由于开关专业与继电保护专业在认识上存在的差异从而使其二次控制回路功能上存在不完善的地方,如直流控制回路和交流电机回路之间的配合、非全相控制回路问题,可能会导致开关刀闸误分合,本文将这些地方一一指出并提供了一些解决办法,同时也提出了一些可以进一步优化和改进的地方,可供其他单位安装调试时参考和借鉴。

The outdoors GIS of Xi＇an SHIKY high voltage electric Co.,Ltd is used in the 220 kV transformer substation in the Fuzhou Electric Power Bureau. In the process of installation and debugging, we discover its control circuit function exist some not perfect places,because of the different understanding between switch profession and electricity protection. Such as the working in direct current control circuit and exchanges electrical engineering circuit, non-full phase control circuit problem not and all. They may cause the switch and isolating switch mistake opening and closing. This paper points out these places one by one and provides some solutions. It also puts forward some places that can be further excellent to turn and improve, can be a reference for other unit＇s installation and debugging.
