Options
N13
Circuit breaker at the converter input
(SINAMICS GM150, for 24-pulse Basic Line Module on
request; not available for the IGCT version with converter
units operated in parallel; SINAMICS SM150 in the
IGCT version on request)
Option
N13
provides integrated circuit breakers. Option
N13
is particularly important in the retrofit business where existing
circuit breakers do not meet requirements (tripping times, low-
voltage coil). The circuit breakers are installed below the Basic
Line Module in the converter cabinet and are thus located on the
secondary side of the line-side transformer.
Notice:
Option N13 increases the width of the cabinet as follows:
•
SINAMICS GM150 in the IGBT version: 600 mm
•
SINAMICS GM150 in the IGCT version: 2 × 700 mm
Note:
In conjunction with option
C55
(auxiliary power supply for open-
loop and closed-loop control), as well as for converters with
24-pulse Basic Line Module, for option
N13
a special request is
required.
N15
24-pulse Basic Line Module (SINAMICS GM150)
For particularly high requirements regarding low line harmonics,
the power units of voltage ranges 2.3 kV, 3.3 kV and 4.16 kV
can be equipped with a 24-pulse Basic Line Module. (circuit
version (2) for IGBT version, circuit version (8) for IGCT version).
Converters with higher power ratings with power units con-
nected in parallel can also be operated without this 24-pulse
option (circuit version (3)). The converter transformer required at
the medium-voltage level must be designed as a five-winding
transformer, or else two two-tier transformers must be provided.
Vector groups and winding offsets must be appropriately
engineered.
Notice:
With the option
N15
the width of the converter cabinet for
SINAMICS GM150 as IGBT version increases by 600 mm.
Note:
For SINAMICS GM150 in the IGCT version, option
N15
cannot
be combined with option
L72
(Braking Module), and a request is
required in conjunction with option
L48
(make-proof grounding
switch at the converter input).
(2) SINAMICS GM150 in IGBT version, basic circuit 2.3 kV to 4.16 kV (Option
N15
)
(3) SINAMICS GM150 in IGBT version, parallel connection 2.3 kV to 4.16 kV (24-pulse infeed as standard)
(8) SINAMICS GM150 in IGCT version (option
N15
)
