Check Method
Perform the switch-on and switch-
off test on the ACB of the LV
panel.
Perform a leakage simulation test
on the residual current circuit
breaker. Press the test button to
verify that the circuit breaker
works properly.
Check that the real-time
temperature of the oil
temperature indicator is normal. If
the difference between the
temperature and the temperature
displayed on the SmartLogger
exceeds ±2°C, the oil temperature
indicator is faulty and needs to be
repaired in a timely manner.
Check the SF
gas pressure gauge
6
to see that the pointer is in the
green range. If the pointer is close
to red, stop running the ring main
unit in a timely manner and
perform a refill.
Check that the heat exchanger
produces no abnormal sounds
during operation.
Test the transformer oil
(chromatography analysis,
dielectric voltage withstand test,
and micro water test).
Clean the surface of the
transformer oil tank, conservator,
and heat sink, and tighten the
bolts of the anchors, grounding
circuit, and main circuit.
Perform manual operation tests
on the operation mechanism to
check its flexibility. If it fails to be
closed or opened, repair the
operation mechanism in time.
