To provide a power conversion device housing and a housing of a railway vehicle power conversion device and a power conversion device in which damage on a power conversion device body and wiring of the power conversion device body accommodated in a housing body can be suppressed.SOLUTION: A power conversion device housing 100 comprises: a box-shaped housing body part 1 for storing a power conversion device body 200a; and a tabular reinforcement member 2 arranged on an inner surface 100a of the housing body part 1 so as to be adjacent to the device body 200a. The reinforcement member 2 comprises: a surface 2a to face the inner surface 100a; a surface 2c arranged almost orthogonally to the inner surface 100a of the housing body part 1; and a surface 2e bent toward the inside of the reinforcement member 2 from the surface 2c. The reinforcement member 2 includes a slit part 2g which is arranged in a bending portion 2f between the surfaces 2c and 2e and functions as a welding position for welding the reinforcement member 2 to the inner surface 100a.SELECTED DRAWING: Figure 2
【課題】筐体本体部に収容されている電力変換装置本体および電力変換装置本体の配線が損傷するのを抑制することが可能な電力変換装置用筐体、鉄道車両用電力変換装置の筐体および電力変換装置を提供する。【解決手段】この電力変換装置用筐体100は、電力変換装置本体200aを収納する箱状の筐体本体部1と、筐体本体部1の内表面100a上において、電力変換装置本体200aと隣接するように配置された板状の補強部材2と、を備える。補強部材2は、内表面100aに対向する面2aと、筐体本体部1の内表面100aに略直交するように設けられる面2cと、面2cに対して補強部材2の内側に向かって折り曲げられる面2eとを含む。また、補強部材2は、面2cと面2eとの間の折り曲げ部分2fに設けられ、内表面100aと補強部材2とを溶接するための溶接箇所となるスリット部2gを含む。【選択図】図2
