Description
● When a minor fault occurs on the
transformer, the oil of the transformer
generates gas. The gas will rise and
enter the gas relay. In this case, the reed
switch contact for gas accumulation will
be closed to send signals. When there is
too much gas, it can be released
through the gas nozzle of the gas relay.
● When there is a strong gas flow in the
transformer, the reed switch contact for
oil flow will be closed and the circuit
breaker of the ring main unit will trip.
● Oil refilling: Refills the transformer oil
using an uncontaminated metal or non-
rubber hose and oil injection equipment.
(Note: Prevent air from entering.)
● Oil draining: Lead the transformer oil to
a container using an uncontaminated
metal or non-rubber hose.
Displays the top layer of transformer oil in
real time and issues alarms and trip signals
through the built-in temperature control
switch.
