Protective devices
Tap-change supervisory control
The COMTAP® ARS is equipped with a tap-change supervisory control,
which is fitted in a housing on the head of the COMTAP® ARS (see page
[
► 34]).
Depending on the application, the tap-change supervisory control may have
different safety functions in conjunction with the motor-drive unit and the as-
sociated on-load tap-changer units.
These safety functions are specified individually in a binding manner for
each delivery depending on application and documented in an associated
functional description.
Electrical tripping contact/interlocking contact
When combining the COMTAP® ARS with on-load tap-changers, the
COMTAP® ARS may only be actuated in a certain on-load tap-changer posi-
tion. This means that it may only be actuated when all windings of the on-
load tap-changer tap winding are disconnected and the voltage at the rele-
vant winding is therefore zero.
For this reason, non-permitted switching operations are prevented by a mu-
tual electrical interlock of the on-load tap-changer and COMTAP® ARS.
Please refer to the order-specific technical documentation, safety instruc-
tions, and functional description.
Drive shaft
Function description
The drive shaft is the mechanical connection between motor-drive and on-
load tap-changer head / de-energized tap-changer head.
