The present invention relates to an isolation switching device (110) for protecting an on-board power supply (100) against a short circuit (101) in one or more paths of a distributor (140) connected to the on-board power supply (100), the disconnector arrangement (110) comprises the following components: a parallel circuit which is composed of a first current path (111) and a second current path (112) and can be connected between a battery connection (160) of the on-board power supply (100) and a distributor (140), the first current path (111) comprising a first switch (120) with at least one disconnector element (121), and the second current path (112) comprising a second switch (120) with at least one disconnector element (121). The isolation element is designed to open the first current path (111) when the current in the distributor (140) increases in response to exceeding a first current threshold, and the second current path (112) comprises a resistor (113) designed to limit a current increase in the second current path to a second current threshold.
本文涉及一种用于在连接到车载电源(100)的配电器(140)的一个或多个路径中防短路(101)保护车载电源(100)的隔离开关装置(110),其中,该隔离开关装置(110)包括以下组成:由第一电流路径(111)和第二电流路径(112)组成的能连接在车载电源(100)的电池接头(160)和配电器(140)之间的并联电路,其中,第一电流路径(111)包括具有至少一个隔离元件(121)的第一开关(120),该隔离元件设计成:当该配电器(140)中的电流响应于超过第一电流阈值地增大时断开第一电流路径(111),其中,第二电流路径(112)包括设计成将第二电流路径中的电流增大限制到第二电流阈值的电阻(113)。
