<P>PROBLEM TO BE SOLVED: To provide ground-based transformer equipment which can suppress an increase in temperature of a ventilation hole formed in a side wall of a casing without an increase in size of a transformer. <P>SOLUTION: A reflection board 11 which is formed to block part of a ventilation hole 3 formed in a side wall 101 of a casing 1 and reflects an air flow discharged outside from inside the casing via the ventilation hole 3 is provided on the inside of the ventilation hole 3. The reflection board 11 is disposed on the inside of a part of the ventilation hole 3, the outer surface of which has the highest temperature when a transformer is operated without the reflection board 11. <P>COPYRIGHT: (C)2010,JPO&INPIT |
