<strong>Synchronous</strong> <strong>Generators</strong> <strong>BG</strong> <strong>132</strong> / <strong>BG</strong> <strong>160</strong><br />
Chapter 4: 4.6 Installation of two-bearing generators (<strong>BG</strong> <strong>132</strong>)<br />
Minimum clearances (<strong>BG</strong> <strong>132</strong>, twobearing<br />
types)<br />
The following minimum clearances towards<br />
parts or walls have to be observed for<br />
installation (see also the accompanying<br />
figures on the right):<br />
• Both sides <strong>and</strong> top: a = 100 mm<br />
• Front side: b = 200 mm<br />
• Rear side: c = 170 mm<br />
Cooling (<strong>BG</strong> <strong>132</strong>, two-bearing types)<br />
It is absolutely important to observe the<br />
following regulations for cooling. Danger<br />
of overheating!<br />
The temperature of the supplied cooling air<br />
must not exceed 40 °C.<br />
In the cooling air intake area on the rear<br />
side of the generator a maximum partial<br />
vacuum of P max = 4 Pa may arise.<br />
Otherwise the fan impeller cannot suck<br />
enough cooling air.<br />
In the cooling air blow out area on the<br />
front side of the generator a maximum<br />
overpressure of P max = 7 Pa may arise.<br />
Otherwise the circulation of the cooling air<br />
is not sufficient.<br />
Cooling air circulation must not be<br />
impaired by other air flows (e.g.<br />
directed from the side or from the front<br />
to the generator).<br />
