摘要： A circuit breaker/disconnector apparatus for use in a power delivery system comprises a unidirectional DC circuit breaker which has a first terminal and a second terminal and is configured to automatically open during an overcurrent condition in a forward direction and to remain closed independent of current level in a reverse direction. A disconnector switch is in series with the circuit breaker. The disconnector switch has a first terminal for connecting to a first polarity connector of a power supply, a second terminal for connecting to a second polarity connector of the power supply and a common terminal connected to the first terminal of the circuit breaker. The disconnector switch has at least a first position in which the first terminal is connected to the common terminal and a second position in which the second terminal is connected to the common terminal. The second polarity connector of the power supply may be coupled to a track of a transport system and the second polarity connector of the power supply may be coupled to a live overhead cable or live third rail of a transport system. The apparatus can be used to safely ground the live cable or third rail when in a maintenance condition.
摘要翻译： 用于功率输送系统的断路器/隔离开关装置包括具有第一端子21和第二端子22的单向直流断路器20，该第一端子21和第二端子22被配置为在正向方向上在过电流状态期间自动打开并且在反向方向上独立于电流电平保持闭合 。 与断路器串联的断路器开关10具有用于连接到电源1的第一极性连接器2的第一端子11，用于连接到电源的第二极性连接器3的第二端子12以及用于连接到电源1的第二极性连接器2的公共端子13 连接到断路器的第一端子。 隔离开关具有至少第一位置和第二位置，在第一位置中第一端子连接至公共端子，在第二位置中第二端子连接至公共端子。 电源可以用于诸如铁路或电车轨道之类的运输系统。 在维护条件下，该设备可用于安全接地正常带电电缆或第三条导轨。
