Background

The resin insulation dry-type transformer is a device for transforming voltage, current and impedance by using electromagnetic mutual induction. Mainly comprises an iron core, windings, insulation and leads, and is one of the most commonly used dry transformers.

The traditional transformer generally adopts fan temperature control, accelerates the heat transfer of inside medium and outside air through inside wind circulation, reduces dry-type transformer internal temperature, but fan working area is big, so leads to the pertinence poor, and then leads to the air current that the fan produced to be wasted mostly. However, the patent number is: the prior art of CN219143934U also allows for targeted cooling, but its cold zone is sleeved outside the coil, so that it can only be assembled if the transformer is assembled, and replacement is very inconvenient once the late cooler is damaged.
