Abstract: An electric line cutter device for high voltage busbars has a two-part housing, a piston, an igniter and a busbar. The upper housing includes a cylinder, cuboid or prism chamber. The lower housing also includes a cylinder, cuboid or prism chamber. The piston is contained inside one of either the upper housing chamber or the lower housing chamber. Upon igniting the igniter, the piston breaks a portion of the busbar moving the piston and the portion of the busbar into the opposite chamber thereby stopping the electric current flow. The piston is at least partially formed as an insulator to prevent electric discharge. The piston design together with chamber design includes integrated “squeeze areas” and “blow channels” for the appearing arc. A channel system outside or from inside the piston allow the pyro gases to push the arc plasma into a filter system to cool down the gases.

Abstract: An igniter 40 activated blocking device 10 blocks a fluid line 4 adapted to carry fluid. The blocking device 10 has a housing 30 disposed about the fluid line, a piston 20 housed in the housing, and an igniter 40 that when activated propels the piston 20 to block the fluid line 4. The igniter 40 generates a shock wave to move the piston 20 to block the line. The piston 20 crushes or squeezes a portion of the line 4 to close the line.
