Zusammenfassung: | To provide a power conversion device that can prevent foreign substances such as rainwater and dust from entering a control box through a hood opening.SOLUTION: In the power conversion device, a control unit A includes drainage plates 12, 13, which prevent rainwater, etc., from entering hoods 4, 5, for intake and exhaust, and nets 10, 11 for preventing foreign substances from entering disposed on both hoods 4, 5. Rainwater that has entered beyond the drainage plates 12, 13 is discharged to the outside through cutouts formed in the drainage plates 12, 13. In addition, integrally forming gallery sheet metal parts 8, 9 on both hood inner side parts 4b, 5b prevents rainwater from leaking into a control box 1 from the inner side of the hoods 4b, 5b so as to reliably prevent internal equipment 6 in the control box 1 from malfunctioning even if rainwater penetrates to the inner side of the hoods 4b, 5b.SELECTED DRAWING: Figure 1
【課題】フード開口部から制御箱内へ雨水や塵埃等の異物が制御箱内へ侵入することを防止できる電力変換装置を提供する。【解決手段】電力変換装置において、制御部Aは、吸気用フード4や排気用フード5内に雨水等の侵入を防止する水切り板12、13及び両フード4、5には異物の侵入を防止するネット10、11を備える。水切り板12、13を超えて侵入した雨水は、水切り板12、13に形成した切り欠きから外部へ排出する。さらに、両フード内側部4b、5bにギャラリー板金部8、9を一体成型することにより、仮に、フード内側部4b、5bまで雨水が侵入したとしても、フード内側部4b、5bから制御箱1内へ雨水が漏出することを防止し、制御箱1内の内部機器6が故障することを確実に阻止する。【選択図】図1 |
