Circuit Breakers, we know all about it.
The circuit
breaker must detect an
over-current condition
and this is usually done
within the breaker
enclosure. Circuit
breakers for large
currents or high
voltages are usually
arranged with pilot
devices to sense a fault
current and to operate
the trip opening
mechanism. The trip
solenoid that releases
the latch is usually
energized by a separate
battery, although some
high-voltage circuit
breakers are
self-contained with
current transformers,
protection relays, and
an internal control
power source.
Once a fault is
detected, contacts
within the circuit
breaker must open to
interrupt the circuit;
some mechanically-stored
energy (using something
such as springs or
compressed air)
contained within the
breaker is used to
separate the contacts,
although some of the
energy required may be
obtained from the fault
current itself. Small
circuit breakers may be
manually operated;
larger units have
solenoids to trip the
mechanism, and electric
motors to restore energy
to the springs.
The
circuit breaker contacts
must carry the load
current without
excessive heating, and
must also withstand the
heat of the arc produced
when interrupting the
circuit. Contacts are
made of copper or copper
alloys, silver alloys,
and other materials.
Service life of the
contacts is limited by
the erosion due to
interrupting the arc.
Mechanical circuit
breakers are usually
discarded when the
contacts are worn, but
power circuit breakers
and high-voltage circuit
breakers have
replaceable contacts.
When a current is
interrupted, an arc is
generated. This arc must
be contained, cooled,
and extinguished in a
controlled way, so that
the gap between the
contacts can again
withstand the voltage in
the circuit. Different
circuit breakers use
vacuum, air, insulating
gas, or oil as the
medium in which the arc
forms.
All circuit breakers
have common features in
their operation.
although details vary
substantially depending
on the voltage class,
current rating and type
of the circuit breaker.
