Causes Of Oil Distribution Transformer Burnout

In the daily use of oil distribution transformer, there will be some burnout phenomena. Once the oil-immersed transformer is burned out, it may cause many accidents. Therefore, find out the reason for the burnout of the oil-immersed transformer and take corresponding precautions.

The main reasons for oil distribution transformer to burn out are:

1. Overload.

In layman's terms, it is the phenomenon of small horse-drawn carts. Of course, it may also be overloaded due to the increase in electricity consumption due to changes in seasons or weather.

2. The use of oil-immersed transformer oil is unreasonable.

The oil-immersed transformer oil is different from the box oil. The oil-immersed transformer oil is mixed. Second, the oil distribution transformer is not refueled according to the normal procedure.

3. Improper reactive power compensation causes resonance overvoltage.

In order to reduce wire loss and improve equipment utilization, if the compensation is not equal to the total capacitive reactance and total inductive reactance on the line, ferromagnetic resonance will occur in the running line and equipment, causing voltage and overcurrent, which will lead to oil immersion The transformer is damaged.

4. Lightning weather causes overvoltage.

5. The tap changer is in poor contact.

Fundamentally, this is related to the quality of the oil-immersed transformer. If the oil-immersed transformer has an unreasonable structure or poor contact of the joints, etc., it may cause one or another problem in the oil-immersed transformer.

6. The respirator hole is blocked.

Of course, the burnout of the oil distribution transformer may also be the cause of man-made damage, which may cause the oil-immersed transformer to fail in one way or another.
