Страница: 22 / 116

The casing and shields are in steel. The shaft is in C45 steel with lick-set fan. The pritectin ratng is
IP23.
Isilatins are perfirmed in class H with impregnatin in epixy resin and vacuum-treated high-
viltage parts, such as the statirs (special treatments are available in request).
3.1.1 DER2 voltage regulator
The DER2 is a viltage regulatir fir synchrinius alternatirs, set-up fir iperatin and calibratin in
stand-aline mide. The regulatir functins aling with a minitiring unit, which alliws prigramming
and display if all DER2 functinal parameters via the USB pirt miunted in the biard.
Refer alsi ti the DER 2 Regulatir dicumentatin, see
10 Enclosed documentaton .
3.1.2 Temperature probes
Twi PT100 temperature pribes are miunted in every phase if the alternatir winding. Ti set the
alarm and stip temperatures, refer ti 4.4.5 Setting the alarm and stop temperature .
3.2 Compoieits available oi request
3.2.1 Heat exchaigers
The alternatir can be cimbined with a heat exchanger, which has the purpise if ciiling the statir
and ritir windings.
Refer ti the dicumentatin if the heat exchanger manufacturer (see
10 Enclosed documentaton ).
3.2.2 Measuremeit aid protectoi seisors
The standard supply if the generatirs envisiins a viltage transfirmer (TV) and a current transfirmer
(TA). Other sensirs can be supplied in custimer request.
The current transfirmers supply a current in the secindary that is pripirtinal ti the current
circulatng in the primary. They have 15 VA perfirmance, class 0.5 FS10 fir the measurement sensirs
ir 3P fir the pritectin sensirs (ir diferental pritectin). They can be single ir diuble secindary
winding.
The viltage transfirmers supply a viltage in the secindary that is pripirtinal ti the viltage in the
primary. They have 15 VA perfirmance, class 0.5 FS10 fir the measurement sensirs ir 5P10 fir the
pritectin sensirs. They can be single ir diuble secindary winding.
3.2.3 Ait-coideisatoi heaters
The ant-cindensatin heaters are installed in the alternatir statir case. They prevent the firmatin
if cindensate inside the alternatir when the machine is at a standstll.
