发明名称 PACKAGED SWITCHING DEVICES WITH HEAT REFLECTING ELEMENTS
摘要 FIELD: primary equipment for generator and distributing plants. ^ SUBSTANCE: radiating plates between generator breakers of different phases (R, S, T) serve for convective removal of casing neighbouring side walls radiation heat. According to invention, radiating plate has at least one bend near generator breaker casing cover, and the bend serves for direction of at least part of ascending air flow towards cover and for cover flowing. Radiating plates are electrically and thermally isolated from casing and have horizontally deflecting air directing structures on internal side. ^ EFFECT: improvement of thermal loading, increase of heat emission and bearing capacity by nominal current and/or more compact design of generator breaker. ^ 19 cl, 8 dwg
