<P>PROBLEM TO BE SOLVED: To efficiently cool a breaker by attaching a simple structure object to an existing switch gear, thus forming a flow of cooling air around the breaker, and to improve cooling efficiency by simple attachment work even if it is the existing switch gear. <P>SOLUTION: The cooling air is taken in through an air intake port 9 which is opened to a side surface of a housing body 2 for the switch gear, the flow of the cooling air is changed into a horizontal direction by colliding it with the baffle body 11 provided so that the longitudinal direction may become a roughly vertical direction toward the breaker 8 including the electric appliance in the basket body 2 for the switch gear, and the air for cooling is discharged from an air exhaust port 10 which is opened to the side surface of the housing body 2 for the switch gear after guiding of the cooling air to front/rear surfaces of the breaker 8. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
