Does the transformer need an oil change?

The oil-immersed transformer works with transformer oil, and only the transformer oil conforms to the operation of the oil-immersed transformer will make the oil-immersed transformer run more complete and the efficiency will be more improved. Oil-immersed transformer to do a variety of oil change work, oil-immersed transformer does not need to change the oil often, but it is also necessary to ensure that two to three times a month, so that the transformer oil will be more fresh and more powerful. In addition, it is necessary to carry out continuous inspection, and what are the specific contents of the inspection?

In general, whether the oil-immersed transformer needs an oil change needs to be checked regularly:

1. Check the oil temperature

Under normal circumstances, because the operation of the transformer makes the transformer oil temperature inevitably rise, however, there will be a certain range, not more than 85 degrees, when the oil temperature is too high to see whether the transformer is overloaded, if it is to reduce the load current, indoor ventilation and heat dissipation should be strengthened.

2. Check the oil quality

The main thing is to see whether there are impurities, precipitates, etc., in the transformer oil, which will lead to the deterioration of the transformer oil and affect its use effect. In order to ensure that transformer oil plays its important role, Xiaobian reminds us that we can regularly check the three aspects of transformer oil level, oil temperature and oil quality, and once the problem is found, it is targeted to solve.

3. Check the oil level

The oil level mainly reflects the amount of transformer oil, the amount of transformer oil must not be too low, once the amount of oil is too small, it will inevitably make all aspects of the performance decline, the overall loss of the transformer will increase, which has a great adverse effect on the transformer.
