        摘 要:介紹了雙母線變電站中隔離開關所需開合的母線轉換電流能力要求差異,計算了隔離開關所需開合的母線轉換電流和斷口電壓大小,給出了提高隔離開關母線轉換電流能力的措施,并以 252 kV GIS 隔離開關為例,證明了提高分合閘速度的設計對高參數母線轉換電流試驗的有效性。
        關鍵詞:雙母線變電站;隔離開關;母線轉換電流

        Abstract: 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.
        Key words: double busbar substation; disconnector; bus-transfer current
