7.1.2
K66
Power section with internal cooling (SINAMICS GM150 in water-
cooled IGBT version; SINAMICS GM150 and SINAMICS SM150 in
IGCT version on request)
When using option K66, the power sections can be operated without having to feed
in external cooling air. They have internal air circulation with an air-water heat
exchanger, and they have no air ventilation slots.
When using option K66, the impact of damaging environmental effects in operation
is restricted to a safe level. The following list provides an overview of the relevant
environmental effects:
•
Heat
•
Ingress of chemicals (soot and sulfur)
•
Moisture
•
Ingress of damaging substances (conductive dusts)
Note
Within the context of the environmental conditions specified in the catalog, the
environmental effects mentioned above are not damaging. However, if the limit
values of the corresponding environmental classes can be exceeded, then option
K66 should be selected for the converter.
During storage and transport, option K66 does not provide any protection against
damaging environmental effects.
Note
The degree of protection can be increased to IP44 by selecting option K66.
Note
•
When option K66 is selected, the deionized water requirement of the cooling
unit is greater than that specified in the technical data. The additional deionized
water requirement is as follows:
– for single circuit configurations: 12 l
– for parallel circuit configurations: 18 l
•
Option K66 cannot be combined with option M61 (redundant fan in the power
unit) or Y26 (pre-magnetizing unit), and an inquiry is required in conjunction with
options N15 (24-pulse Basic Line Module) and N16 (36-pulse Basic Line
Module).
