Farady oil immersed power transformer

Oil-immersed power transformers in operation,substations and transformers winding and core heat the oil first pass, and then passed through a cooling medium oil. Cooling oil-immersed power transformers, according to the size of the capacity can be divided into the following categories:
1, the natural oil circulation natural cooling (ONAN type)
2, natural oil circulation-cooled (air-cooled oil-immersed) 3, forced oil-cooled 4-cycle water, forced oil circulation air cooling oil type transformer should pay particular attention to their fire safety measures.
