How it works:
This series cooling fan is used in dry type transformer, the fan is placed on both sides of the lower part of the transformer coil, blowing the cold air directly into the coil of the transformer high and low pressure cooling air ducts, the heat dissipation effect is obvious, which can guarantee the normal operation of the transformer and prolong its service life. (Fan start, stop and transformer over-temperature alarm, over-temperature tripping and other functions are provided by the temperature control device).
