[0020] The present invention will be further described in detail below with reference to the drawings and specific embodiments.
[0021] Such as Figure 1~8 As shown, a dry-type transformer cooling device with intelligent frequency conversion function includes a frequency conversion refrigeration compressor, a cooling chamber, a refrigeration system, and a control module that can be automatically controlled by frequency to control the work output, and is characterized in that the cooling chamber is divided into It is an upper shell and a lower shell. The top of the upper shell is provided with a round hole for passing through the high and low voltage bushings of the dry-type transformer. In the cavity of the cooling chamber, a cold medium circulates in the cooling chamber, and the refrigeration system performs a refrigeration cycle on the cold medium to meet the requirements of the cold medium to cool dry transformers. The lower part of the side of the cooling chamber is installe...
