The Galvanic isolation is an option for converters in
the current range 2050...5150 A and rated voltages
1000 V. For converters with a rated voltage of
1190 V and 12-pulse serial > 2x 500 V the galvanic
isolation is a standard equipment. It is used to replace the high-ohmic resistance voltage measurement and gives the advantage of a total isolation
from power part to electronic part.
The transformer T90 and the DC transducer A92
are located outside the converter module. The internal AC and DC voltage measurement channels
are opened and connected to the T90 and A92
units.Remark
The terminals on the primary side of the
transformer are in special design (lug terminals).
Handling hints: First turn the screw conterclockwise to the end stop, then swing out
the shrowding cover. Put in
the cable lug, swing in the
the shrowding cover and
fasten the connection by
turning the screw clockwise.The Power Interface of DCS converter modules
model C3 and C4 from 900 A up to 5150 A consists
of two boards - the Measuring board SDCS-PIN-5x
and the Pulse transformer board SCDS-PIN-41.
There are different versions of the SDCS-PIN-5x:
SDCS-PIN-51 for converters with all line voltages
SDCS-PIN-52 for converters with line volt. 500 V
The following figures show the different connections between the SDCS-PIN-41 and SDCS-PIN-5x
board depending on the application 2- or 4-quadrant and the construction type.
Converters, delivered from 1998 on, will be
equipped with SDCS-PIN-41A, which is a full replacement for converters, which alredy in use.Measuring board SDCS-PIN-5x
This board is always used together with SDCSPIN-41 board. On this board there are the circuits
located needed for current, voltage and temperature measuring and for hardware coding.
The current is measured by current transformers at
the AC supply, rectified by a diode bridge and
scaled with burden resistors to 1.5 V as rated current. The current response is adjusted by cutting
out resistors (R1 ... R21) from the board according
to the coding table. The resistors R22 ... R26 are
used for the current equal to zero detection. These
resistors must be cut off according to a second table.
Voltages (U1, V1, W1 and C1(+) and D1(-)) are
measured by using high ohm resistor chains. Scaling of AC and DC voltage is done by activating 1The power interface board PG 63x0 is used for
converter units type DCP50x. There are 2 different
versions in use. The used types are:
- PG 6320 for 90 A...150 A converters at 400/500 V
- PG 6330 for 250 A...540 A converters at 400/500 V
The PG 63x0 boards consists of:
- firing pulse circuits and pulse transformers
- measurement of the armature current via current
transformers
- snubber circuit for thyristors protection
(consists of RC circuits and MOV elements)
- AC and DC high ohmic voltage measurement
- heat sink temperature measurement via PTC
