ABB BAILEY IMASI23、INNIS21
变频器的使用对环境要求较高，比如在多粉尘场所，尤其是多金属粉尘、絮状物的场所使用变频器时，采用合理的防尘措施对保证变频器正常工作非常重要。变频器防尘控制柜应该密封，变频器防尘控制柜应该通过专门设计的进风口、出风口进行通风;变频器控制柜顶部应该有防护网和防护顶盖出风口;变频器控制柜底部应该有底板和进风口、进线孔，并且安装防尘网。
变频器防尘控制柜的风道要设计合理，排风通畅，这就避免在柜内形成涡流，在固定的位置形成灰尘堆积。
变频器防尘控制柜顶部出风口上面要安装防护顶盖，防止杂物直接落入；防护顶盖的侧面出风口要安装防护网，防止絮状杂物直接落入。
变频器防尘控制柜顶部侧面排风方式，出风口必须安装防护网。
确保变频器防尘控制柜顶部的轴流风机旋转方向正确，向外抽风。如果风机安装在控制柜顶部的外部，必须确保防护顶盖与风机之间有足够的高度；如果风机安装在控制柜顶部的内部，安装所需螺钉必须采用止逆弹件，防止风机脱落造成柜内元件和设备的损坏。建议在风机和柜体之间加装塑料或者橡胶减振垫圈，可以大大减小风机震动造成的噪音。
变频器防尘控制柜的前后门和接缝处，要采用密封垫片或者密封胶进行一定的密封处理，防止粉尘进入。
变频器防尘控制柜要进行定期维护及时清理内部、外部的粉尘、絮毛等杂物。粉尘严重的场所，维护周期在1个月左右，环境好的场所可以2-3个月清理一次。
变频器的装置设计基本要求
1变频器应该安装在控制柜内部。
2变频器最好安装在控制柜内的中部;变频器要垂直安装，正上方和正下方要防止装置可能阻挡排风、进风的大元件。
3变频器上、下部边缘距离控制柜顶部、底部、或者隔板、或者必需装置的大元件等的最小间距，应该大于300mm
4如果特殊用户在使用中需要取掉键盘，则变频器面板的键盘孔，一定要用胶带严格密封或者采用假面板替换，防止粉尘大量进入变频器内部。
5对变频器要进行定期维护，及时清理内部的粉尘等。
6其它基本装置、使用要求必需遵守用户手册上的有关说明;如有疑问请及时联系相应厂家技术支持人员。
防尘控制柜的规划需求
多粉尘场所，特别是多金属粉尘、絮状物的场所运用变频器时，采取正确、合理的防护办法是十分必要的防尘办法妥当对保证变频器正常作业非常重要。总体需求控制柜整体大概密封，大概通过专门规划的进风口、出风口进行通风;控制柜顶部大概有防护网和防护顶盖出风口;控制柜底部大概有底板和进风口、进线孔，而且设备防尘网。
1控制柜的风道要规划合理，排风晓畅，避免在柜内构成涡流，固定的位置构成灰尘堆积。
2控制柜顶部出风口上面要设备防护顶盖，避免杂物直接落入;防护顶盖高度要合理，不影响排风。防护顶盖的正面出风口要设备防护网，避免絮状杂物直接落入。
3假如选用电子元器件控制柜顶部正面排风方法，出风口必需设备防护网。
4必定要保证控制柜顶部的轴流风机旋转方向正确，向外抽风。假如风机设备在控制柜顶部的外部，必需保证防护顶盖与风机之间有满足的高度;假如风机设备在控制柜顶部的内部，设备所需螺钉必需选用止逆弹件，避免风机脱落形成柜内元件和设备的损坏。主张在风机和柜体之间加装塑料或许橡胶减振垫圈，可以大大减小风机轰动形成的噪音。
5控制柜的前、后门和其他接缝处，要选用密封垫片或许密封胶进行必定的密封处置，避免粉尘进入。
6控制柜底部、侧板的一切进风口、进线孔，必定要设备防尘网。隔绝絮状杂物进入。防尘网大概规划为可拆卸式，以便利整理、保护。防尘网的网格要小，可以有用阻挠细微絮状物(与通常家用防蚊蝇纱网的网格相仿);或许根据具体情况断定合适的网格尺寸。防尘网附近与控制柜的联系处要处置紧密。
7对控制柜必定要进行定时保护，及时整理内部、外部的粉尘、絮毛等杂物。保护周期可根据具体情况而定，但大概小于23个月;对于粉尘严峻的场所，主张保护周期在1个月摆布。
