摘要
分析了变压器励磁涌流及因其产生的和应涌流,电压跌落等问题对供配电系统稳定运行的影响,基于剩磁计算原理的涌流抑制技术和传统基于固定角度分合闸进行涌流抑制产品的区别,及采用该技术在海上设施完美解决三相联动操动机构AIS及GIS断路器回路变压器涌流和电压跌落问题的实例。
The influence on power transmission and distribution system by transformer inrush current,and concomitant sympathetic inrush current,voltage dip is analyzed.It then discussed the difference between inrush current restrain base on residual flux calculation method and traditional fix angle switching method,In the end,it shows the excellent result the technology used in offshore facilities that equipped with gang-operated AIS & GIS circuit breakers.
