Oil-immersed transformer is also a kind of transformer, its main feature is the transformer coil and magnetic core immersed in the special transformer oil, so that not only can achieve heat dissipation, but also effectively insulate the coil from air, to prevent air corrosion to the coil and iron core, in addition, oil-immersed transformer and It has a certain arc extinguishing effect.

Oil-immersed transformer can be installed indoors or outdoors, but its environmental temperature and humidity requirements are relatively high, so when using oil-immersed transformer, to ensure that the use of the environment to meet the requirements, so as to play the greatest performance of oil-immersed transformer, in addition, oil-immersed transformer The use of the device needs to be on guard, mainly because the transformer oil temperature is too high, may cause explosion accidents.

The role of oil immersed transformers:

1. Oil immersed transformers play a major role in cooling and cooling during operation.

2, the winding and other insulation and insulation maintenance role;

3. Oil-immersed transformer plays a role in eliminating soliton at high-voltage lead and tap-changer contact point to prevent corona and solitary discharge.

Simply put, the oil-immersed transformer has the main role of the above several aspects, can effectively protect the use of oil-immersed transformer safety, long service life.
