Two types of oil immersed power transformer

One types of oil immersed power transformer ,The usual transformers are double-winding transformers, that is, there are two windings on the core, one for the original winding, one for the secondary winding.
Another type of oil immersed transformer Three-winding transformers are larger capacity transformers (above 5600 kVA) to connect three different voltage lines. In special cases, there are transformers that use more windings.

oil type transformer, reason for the temperature rise

In the oil type transformer are generally used in a class of insulation, insulation heat resistance of 105 ℃.
As the ambient temperature is generally lower than 40 ℃, so the transformer winding temperature generally reach the limit operating temperature.
oil immersed distribution transformer ,Even in a short time to reach 105 ℃, because the time is very short, the insulation of the winding is not directly dangerous.

application performance of oil immersed transformer

The oil immersed transformer can be safely reduced to the user can safely use the voltage to ensure that people can safely use electricity.In the use of transformers, pay attention to oil and dry processing workers and, if the oil transformer for a long time not used, running time Too long or other aspects of the situation may cause changes in transformer insulation, internal water or deterioration of oil and other phenomena, must be timely for the transformer oil and drying treatment, to further enhance the application performance of oil-immersed transformers.
