Definitions for safety device
Wikipedia
In engineering, a fail-secure is a design feature or
practice that, within the occasion of a selected kind of failure, inherently
responds in a way order to cause minimal or no damage to other gadgets, the
surroundings, or people. Unlike inherent safety to a particular hazard, a
machine being "fail-safe" no longer means that failure is impossible
or implausible; instead, the machine's layout prevents or mitigates dangerous
outcomes of the device's failure. That is, if and when a "fail-secure"
system fails, it stays at the least as secure because it turned into before the
collapse. Since wide varieties of failure are viable, failure mode and outcomes
analysis is used to look at failure conditions and propose safety layouts and
approaches. Some systems can in no way be made fail-safe, as continuous
availability is wanted. Redundancy, fault tolerance, or contingency plans are
used for these situations (e., G. More than one independently controlled and
fuel-fed engine). techiescity
The Standard Electrical Dictionary
(a) A device to prevent overheating any portion of a circuit
by an excess of modern. It usually consists of a slip of fusible steel, which
melts and opens the circuit if the present day attains too much power. A weight
is occasionally suspended from the strip to ensure it's breaking. In one form,
an insulated German silver twine is wrapped across the end of the fusible strip
in some instances, and its future is hooked up to it. The other give up of the
German silver wire connects with the principle lead, so that all the modern-day
is going thru both in series. If the German silver cord turns heated from an excess
of modern, the coil wrapped tightly across the top of the fusible strip melts
it and opens the circuit. (b) Lightning arresters, q. V. can be cited
underneath this heading. Synonyms--Automatic Cut Out--Safety Fuse, Plug, or
Strip. techiesin
