Abstract: The necessity of main transformer cooling mode reformation was expounded. The heat dissipation effect was analyzed. The numerous operation data after reformation were collected. The practical oil temperature rise of top layer was compared with theoretic calculation results, which shows that the reformation was effective.

Key words: cooling mode, heat dissipation effect, technical reformation, comparison
