1.1 Safety instructions
Make sure that the personnel who install, put into service and operate the
“MB 103 Temperature Control Unit”:
·
Are technically qualified and competent;
·
Fully comply with these assembly instructions.
Improper operation or misuse could endanger:
·
Life
and
limb
·
The equipment and other property of the operator
The safety instructions in this manual are shown in three different forms to emphasize the importance of the operation.
1.2 Specified applications
The “MB 103” Temperature Control Unit is used in resin or dry type transformers and can also be easily adapted for use in oil
transformers.
The “MB 103” Temperature Control Unit uses PT100 temperature probes for constant monitoring of transformer temperature in four
points: for example, three on the transformer winding columns and one on the machine's magnetic circuit.
If the transformer fails to function correctly and its temperature rises, the Temperature Control Unit generates an electric alarm signal.
If the temperature reaches danger level, the unit generates a second intervention level. This can be connected to a machine stop switch
that functions independently of the alarms.
A cooling system control program is also implemented in the unit.
WARNING
