摘要
介绍了双母线变电站中隔离开关所需开合的母线转换电流能力要求差异,计算了隔离开关所需开合的母线转换电流和断口电压大小,给出了提高隔离开关母线转换电流能力的措施,并以252kV GIS隔离开关为例,证明了提高分合闸速度的设计对高参数母线转换电流试验的有效性。
This article introduced the difference in the bus-transfer current switching requirements required by the disconnector in the double busbar substation.It calculated bus switching current and fracture voltage for the needs of the disconnector.It also provided suggestions for the current conversion capability of the disconnector.This work takes the 252 kV GIS disconnector as an example.It proves that the switch design for the speed improvement of the opening and closing is effective for the high-parameter bus-transfer current test.
