Oil-immersed transformer installation points

Distribution transformer substations important component of oil-immersed transformer transformer is usually installed in a separate room.
  Rely on oil as a cooling medium, such as oil-immersed self-cooled, oil cooled, oil cooled and forced oil circulation. General step-up substation main transformer are  mcb circuit breaker , the transformation ratio 20KV/500KV, or 20KV/220KV, generally used to drive with its own power plant load (such as mills, induced draft fan, blower, air circuit breaker pumps, etc.) of auxiliary transformer is oil-immersed transformers, it turns ratio is 20KV/6KV.
  All-immersed transformer oil-filled sealed type. Corrugated tank shell to the expansion of their flexibility to adapt to the oil tank is permanently sealed, oil-immersed transformers have been widely used in various power distribution equipment.
