Abstract

The present invention relates to an electrical bypass device having two electrical conductors (1, 2) that are electrically insulated from one another and are arranged such that two surface regions of the two conductors (1, 2) are spaced apart from one another by means of a gap. Above the surface regions there is a bypass element (3) having at least one electrically conductive layer (6, 11, 14, 15), which bypass element is in the form of a mechanical energy store (7) or is connected to a mechanical energy store (8). The mechanical energy store (7, 8) is transferable by thermal triggering from a first mechanical state to a stable second mechanical state in which the electrically conductive layer (6, 11, 14, 15) of the bypass element (3) makes electrical contact with the surface regions and hence shorts the two electrical conductors (1, 2). Arranged above the surface regions there is also a reactive element (4) in which an exothermic reaction can be triggered, as a result of which the mechanical energy store (7, 8) transfers to the stable second mechanical state. The proposed bypass device makes it possible, in the triggered state, for high currents to flow given a low series resistance at the same time, and allows permanent, irreversible bypassing of the monitored component.
