Load duty cycles
Load cycle S1
Continuous duty
. Operation with constant load and long enough to achieve
thermal balance.
Load cycle S1 with current peak
Periodic intermittent duty
. Succession of identical duty cycles each having
a period at constant maximum load and a period at constant rated load. In
this duty cycle, the overheating effect of the start-up current is negligible.
The 5% running factor means that for a 10 second cycle, it works at constant
current Imax (2xInom) for 0.5 seconds and at rated current (Inom) for 9.5
seconds.
Load cycle S6-40
Periodic uninterrupted duty cycle with intermittent load
. Succession of
identical duty cycles, each with a running period under constant load and
another period without load. There is no rest period. The 40% running factor
indicates that for a 10 minute cycle, it works at constant current for 4 minutes
(I S6 -40%) and without load for 6 minutes (with magnetizing current = 0.7 x
rated current In)
.
F. H3/4
Load cycle S1.
F. H3/5
Load cycle S1 with current peak Imax.
F. H3/6
Load cycle S6-40.
