The internal insulating oil of distribution transformer has much higher insulating strength than air, good cooling effect, good arc extinguishing medium, and maintenance and anti-corrosion effect on insulating materials. Therefore, insulating oil is very important for distribution transformer.
The oil level of the conservator of the transformer shall be kept within a certain range. When the oil level of the transformer is too high, it may increase the internal oil pressure of the transformer, and at the same time, it may cause oil overflow. When the oil level is too low, the oil level will also decrease when the transformer is running at low load (or the transformer is out of service), or when the weather becomes cold. When the oil level is lower than the big cover of the transformer, the lead wire or iron core will be exposed to the air, which may cause the risk of internal flashover. At the same time, with the increase of the contact surface between oil and air, the insulating property of insulating oil will decrease rapidly.
It can be seen that the distribution transformer requires a certain oil level in operation, which must be checked frequently. When the oil level is too high, try to drain the oil; when the oil level is too low, try to make up the oil to maintain the qualified oil level.
