The invention relates to a separating device (6) for a high-voltage electrical system (1) of a motor vehicle for separating a high-voltage line (4) of the high-voltage electrical system (1), comprising an overcurrent protection device (F); a first separating unit (T1) which is made of a first actuatable disconnecting unit (A1), said first disconnecting unit (A1) being designed to interrupt a current flow over the first separating unit (T1) in the activated state; a second separating unit (T2) which is made of a second actuatable disconnecting unit (A2) and the overcurrent protection device (F), said second disconnecting unit (A2) being designed to conduct an overcurrent to the overcurrent protection device (F) which interrupts the current flow over the second separating unit (T2) in the activated state; and a control unit (8) which is designed to activate at least the second disconnecting unit (A2) in the event of an overcurrent and to activate at least the first disconnecting unit (A1) in the event of an overcurrent-independent event in order to separate the high-voltage line (4). The invention additionally relates to a high-voltage electrical system (1) and to a motor vehicle.

    本发明涉及一种用于机动车辆的高压车载电网(1)的断开装置(6),该断开装置用于将高压车载电网(1)的高压线路(4)断开,所述断开装置具有过电流保护装置(F);具有通过可控制的第一切断单元(A1)构成的第一断开单元(T1),其中,第一切断单元(A1)在激活状态中设计用于使经由第一断开单元(T1)的电流流动中断;具有通过可控制的第二切断单元(A2)和过电流保护装置(F)构成的第二断开单元(T2),其中,第二切断单元(A2)在激活状态中设计用于,将过电流引导至使经由第二断开单元(T2)的电流流动中断的过电流保护装置(F);并且具有控制单元(8),为了断开高压线路(4),所述控制单元设计用于,在过电流的情况下至少将第二切断单元(A2)激活并且在与过电流无关的事件的情况下至少将第一切断单元(A1)激活。此外,本发明涉及一种高压车载电网(1)以及一种机动车辆。
