The invention relates to an electrical circuit breaker assembly (100) comprising an electrically conductive element (10b) of an electrical circuit (1000) and a cutoff device (110) which can be activated by a pyrotechnic element (112) and which is configured to sever the electrically conductive element (10b) in a cutoff region delimited by a downstream point (10c), the electrical circuit breaker assembly (100) further comprises a contactor element (120) activatable by the pyrotechnic element (122), the contactor element (120) being configured to connect a downstream point (10c) of the severing region to a ground conductor (12) of the electrical circuit (1000) before or while severing the conductive element (10b). The invention also relates to a method implemented in such an electrical circuit breaker (100). Advantageously, it is thus possible to quickly isolate faulty wires in the aircraft and prevent electrical faults from propagating to the remainder of the electrical circuit (1000).
本发明涉及一种电气断路器组装件(100),其包括电路(1000)的导电元件(10b)和切断设备(110),该切断设备(110)能够由烟火元件(112)激活,并且该切断设备(110)被配置成在由下游点(10c)界定的切断区域中割断导电元件(10b),所述电气断路器组装件(100)还包括能够由烟火元件(122)激活的接触器元件(120),该接触器元件(120)被配置成在割断导电元件(10b)之前或在割断导电元件(10b)的同时将切断区域的下游点(10c)连接到电路(1000)的接地导体(12)。本发明还涉及在这种电气断路器(100)中实现的方法。有利地,因此可能快速隔离飞行器中的故障电线并且防止电气故障传播到电路(1000)的其余部分。
