1 Allgemeines
Bei Betrieb größerer Verdichter wer-
den von den Energieversorgungs-
Unternehmen vielfach Maßnahmen
zur Dämpfung des Anlaufstromes
(z. B. Teilwicklungs- oder Stern-Drei-
eck-Start) verlangt, um zu starke
Stoßbelastung des Stromnetzes zu
vermeiden. Derartige Anlaufmethoden
reduzieren das Anlaufmoment des
Verdichtermotors jedoch auf einen
Wert, der ein einwandfreies Hoch-
laufen nur bei geringen Druckunter-
schieden zulässt. Ähnliche Bedingun-
gen liegen bei Antrieb mittels Verbren-
nungsmotor vor. Maßgeblich sind dort
in erster Linie die Leistung des Anlas-
sers sowie der Momentenverlauf des
Motors.

1 General
Electrical power supply companies
very often demand measures to re-
duce the starting current (e.g. part
winding or star-delta start) when large
compressors are operated. This is to
avoid excessive loads on the supply
network. These starting modes reduce
the starting torque of the motor to a
value that only allows an acceleration
to full speed with a small pressure dif-
ference. Similar conditions apply to
the operation with an internal combus-
tion engine. The deciding factors are
the capacity of the starter and the
torque behaviour of the engine.

1 Généralités
Lors du service de compresseurs d'une
certaine importance, les sociétés distribu-
trices d'énergie électrique imposent des
mesures qui permettent de réduire l'appel
de courant au démarrage (tel que démar-
rage à bobinage partiel ou démarrage
étoile-triangle) afin d’eviter les perturba-
tions qui en résultent sur le réseau. Ce-
pendant ces méthodes de démarrage
réduisent généralement le couple de
démarrage de manière qu'un démarrage
correct ne peut être obtenu que pour de
faibles pressions différentielles. On trouve
des conditions similaires, si l'entraîne-
ment se fait à l'aide d'un moteur ther-
mique. Mais dans ce cas, la puissance du
démarreur et la caractéristique de couple
du moteur jouent un rôle prépondérant.
