Synchronous Generators BG 132 / BG 160
Chapter 4: 4.5 Installation for single-bearing generators
Minimum clearances (single-bearing)
The following minimum clearances towards
parts or walls have to be observed for
installation (see also the accompanying
figures on the right):
• All sides: a = 100 mm
• Rear side: b = 170 mm
Cooling (single-bearing)
It is absolutely important to observe the
following regulations for cooling. Danger
of overheating!
The temperature of the supplied cooling air
must not exceed 40 °C.
In the cooling air intake area on the rear
side of the generator a maximum partial
vacuum of P max =4Pa may arise.
Otherwise the fan impeller cannot suck
enough cooling air.
In the cooling air blow out area on the
front side of the generator a maximum
overpressure of P max = 7 Pa may arise.
Otherwise the circulation of the cooling air
is not sufficient.
Cooling air circulation must not be
impaired by other air flows (e.g.
directed from the side or from the front
to the generator).
