摘要
某厂0.4 kV配电室采用双电源单母线分段式供电方式,两段电源通过母联备自投装置互为备用。为了解决配电室现有的母联备自投装置存在起动速度慢、切换方式单一、元器件较多及在切换过程中产生的大的冲击电流等弊端。通过采用新型的"SUE3000备用电源快速切换装置",利用其快速切换、首次同相切换、残压切换、延时切换多种切换模式,达到避免现有切换装置存在的弊端,同时减轻了电源切换瞬间对电机类负载的暂态冲击,降低了原有切换装置在切换过程产生的操作过电压及切换的风险性等。
In order to solve the deficiency of a power supply automatic transfer device such as low starting speed,singel tramsfer mode,more components and big inrush current,a new SUE3000 reserve power supply fast transfer device was used. The different transfer modes are used to avoid the deficiency and reduce the transiemt impulse,lower the operational over voltage and transfer risk.
