The oil immersed transformers in operation should be regularly inspected and monitored in order to detect abnormal phenomena or faults in time and avoid serious accidents.
Items that should be checked and monitored generally include:
(1) Is there any abnormal sound in the oil immersed transformer, such as uneven sound or discharge sound.
(2) Whether the oil level is normal and whether there is leakage or oil leakage.
(3) Whether the oil temperature of the oil immersed transformer is normal (the upper oil temperature should not exceed 85℃ in general).
(4) Whether the casing is clean, whether there are cracks, damage and discharge.
(5) Whether the joint is hot or not.
(6) Whether the explosion-proof membrane of the explosion-proof pipe is complete.
(7) Check whether the Buchholz relay leaks oil and whether the inside is full of oil.
(8) Whether the respirator is unblocked, whether the oil level of the oil-sealed respirator is normal, and whether the silica gel in the respirator is saturated with moisture.
(9) Whether the cooling system of the oil immersed transformer is operating normally.
(10) Whether the ground wire of the casing is in good condition.
