Description
The transformer winding temperature is
displayed through thermal simulation
technology, and the alarm and trip signals
are transmitted through the temperature
control switch.
There are five levels. Level 1 indicates the
maximum tapping value, level 3 indicates
the rated tapping value, and level 5
indicates the minimum tapping value.
The insulation oil is isolated from the
atmosphere through the airbag in the
conservator. The airbag is connected to the
atmosphere through the dehydrating
breather. The dehydrating breather contains
silica gel to absorb moisture and impurities
in the air and maintain good performance
of the insulation oil.
Indicates the oil level of the transformer oil
cabinet and reports the alarms of high and
low oil levels.
If a transformer is faulty, a large amount of
gas is generated, and the pressure of the
insulation oil increases sharply. When the
certain threshold is reached, the
transformer oil is discharged and the
internal pressure of the transformer
decreases to a normal value. At the same
time, a signal is sent to trip the circuit
breaker in the ring main unit.
