Output reactor
The output reactor is used to limit the capacitive charge-reversal
currents of motor cables. Data regarding cable lengths when us-
ing the output reactor can be obtained for specific systems from
your local Siemens sales contact.
The output reactor is located in an additional cabinet unit.
Notice:
When using an output reactor, the following values apply for the
maximum output frequency:
•
SINAMICS GM150 in IGBT version and
SINAMICS SM150 in IGBT version:
150 Hz
•
SINAMICS GM150 in IGCT version and
SINAMICS SM150 in IGCT version:
90 Hz
Notice:
With option
L08
the cabinet width is increased as follows:
•
SINAMICS GM150 in IGBT version and
SINAMICS SM150 in IGBT version:
- Single circuit configuration: 600 mm
- Parallel circuit configuration: 2 × 600 mm
When option
M13
or
M78
is simultaneously selected the width
does not have to be increased.
•
SINAMICS GM150 in IGCT version and
SINAMICS SM150 in IGCT version:
700 mm per converter unit
When option
L49
or
L51/L52
is simultaneously selected, the
width does not have to be increased.
L21
Overvoltage protection AC
(static excitation unit, see Accessories, Chapter 7)
Option
L21
provides type SICROWBAR integrated overvoltage
protection on the input side.
L29
Bidirectional synchronized bypass operation
(SINAMICS GM150 in the IGBT version with induction motor)
Option
L29
offers synchronization with seamless (commutating)
passing of the motor to the line and receiving of the motor from
the line.
The converter synchronizes the motor to the existing line (phase
relation, frequency and voltage). The motor is subsequently
connected in parallel to the line by means of circuit breaker S3
before the output-side circuit breaker S2 opens.
Approx. 100 ms go by according to the response time constants
of the two circuit breakers (opening time and closing time).
Within this period of time the motor commutates from the con-
verter to the line. This ensures smooth passing of the motor to the
line.
If the motor is to be subsequently taken from the line and
operated using the converter again, the commutation process
is executed in the reverse order. The converter is first run up
no-load operation and its output voltage is adapted to the line
voltage (= motor voltage) in its phase relation, frequency and
amplitude. Then circuit breaker S2 is closed before S3 is opened
and the motor is isolated from the line.
This ensures that the motor is received smoothly by the con-
verter so that it can be either operated under variable speed or
shut down under control. Speed-controlled operation during run-
ning up and shutting down does not produce any high starting
and peak transient torques that could damage the mechanical
connection or cause transient and pressure fluctuations in the
process.
