The Magnetising System
Capacitive discharge magnetisers are used where the required
magnetising current is too high to be achieved using direct power from
the mains supply. Depending on the exact requirements of the
geometry
to be magnetised, the material type and the fixture design, this
current is often in the range 5000-10000A but can also be much higher.
A capacitive discharge magnetiser, charges up an internal
capacitor bank to a required voltage level over a short period of
time. This stored energy is then discharged into the magnetising
fixture (in
a much shorter period of time), in a controlled manner, producing the
large required currents and hence magnetising field strength.
Hirst incorporate microprocessor technology in their
magnetisers to safely manage the charging and discharging of the
machine during the magnetising operation making it very safe to use.
