Inventor and patent holder:
Dr. V. Prieb,
Object of the Invention:
A new electrical low-voltage or
high-voltage fuse (breaking memory-fuse) with a breaking insert made of a
Cu-base memory alloy that is especially suitable for electrical aims.
The memory insert makes possible a new simplified fuse
construction with a new-formed casing. The insert made of a Cu-base alloy can be at the same
time enlarge to contact blades and can serve after its rupturing as a triggering indicator.
In the case of overload or short-circuit
currents in the electrical power system, the insert securely fitted in the fuse breaks
itself due to increasing internal mechanical stress at a point with a
calibrated breaking limit.
New Cu-base memory alloys with special for electrical
engineering suitable properties are invented too.
Electronics and electrical engineering, in electrical devices, for switching
them off without arcing when they are subjected to thermal loads, overload and
short circuit currents.
Especially suitable to protect of the 42-V
direct current board net of future auto cars, where the arcing danger is
especially very high at the current interrupting.
