Pyrotechnic safety cutout for switching off electric power circuits has a casing and a safety cutout conductor designed as an exposed conductive part

摘要

An exposed conductive part (4) has a set separation area (7) to be burst open by a propelling charge (29). After separation, remaining conductor sections (8,9) can be expanded on-axis outwards by an expanding blast wave and then be wedged in an expanded position. This is caused by a plastic distortion in a casing (2) for the conductor sections or a crushing element between them.
