| Zusammenfassung: | To provide a highly reliable switch gear capable of preventing insects and the like from entering without reducing a ventilation area of a ventilation tower.SOLUTION: A switch gear (100) is provided with a ventilation communication port (140) formed in a board ceiling plate (100a) and a ventilation tower (200) disposed above the ventilation communication port (140). The ventilation tower (200) is composed of: a ventilation top plate (201) disposed above the ventilation communication port (140); a ventilation plate (202) disposed between an edge of the ventilation communication port (140) and the ventilation top plate (201) and having a plurality of ventilation holes (203); a protruding top plate (204) that extends protruding outward from the ventilation plate (202) at an end of the ventilation top plate (201); and an intrusion preventing ventilation body (206) disposed on the protruding top plate (204) so as to be spaced from the ventilation plate (202) and having an intrusion preventing structure (207).SELECTED DRAWING: Figure 3
【課題】本願は、換気塔の通風面積を減少させることなく、虫などの侵入防止を行うことができ、高信頼性のスイッチギヤを提供するものである。【解決手段】盤天井板(100a)に形成された換気連通口(140)と、換気連通口(140)の上方に配置された換気塔(200)とを備えたスイッチギヤ(100)であって、換気塔(200)は、換気連通口(140)の上方に配置された換気天板(201)と、換気連通口(140)の縁部と換気天板(201)との間に配置され、複数の換気口(203)を有する換気板(202)と、換気天板(201)の端部に換気板(202)より外方に突出して延在する突出天板(204)と、突出天板(204)に換気板(202)と空間を開けて配置され、侵入防止構造体(207)を有する侵入防止換気体(206)とにより構成されたものである。【選択図】図３ |
