变频器柜体及变频器
阅读说明:本技术 变频器柜体及变频器 (Converter cabinet body and converter ) 是由 颜冬亮 仲庆龙 张万宝 于 2018-09-04 设计创作,主要内容包括:本发明提供一种变频器柜体及变频器,该变频器柜体包括:一用于容纳变压器的变压器柜,变压器柜的顶部设置有第一出风口且侧壁上设置有第一进风口;一用于容纳至少一功率单元的功率单元柜,功率单元柜的前侧壁上设置有第二进风口,且功率单元柜的后侧与变压器柜相连通;变压器柜包括有分别设置于次级线圈上端和下端的第一风道挡板和第二风道挡板,使得从功率单元柜进入变压器柜的风可以直吹次级线圈;从第一进风口进入的风可以通过初级线圈及次级线圈后从第一出风口流出变压器柜,从第二进风口进入的风可以依次通过各个功率单元和次级线圈后从第一出风口流出变压器柜。本方案的变频器柜体及变频器,能够降低变频器对风机性能的要求。(The invention provides a frequency converter cabinet body and a frequency converter, wherein the frequency converter cabinet body comprises: the transformer cabinet is used for accommodating a transformer, a first air outlet is formed in the top of the transformer cabinet, and a first air inlet is formed in the side wall of the transformer cabinet; the power unit cabinet is used for accommodating at least one power unit, a second air inlet is formed in the front side wall of the power unit cabinet, and the rear side of the power unit cabinet is communicated with the transformer cabinet; the transformer cabinet comprises a first air duct baffle and a second air duct baffle which are respectively arranged at the upper end and the lower end of the secondary coil, so that the wind entering the transformer cabinet from the power unit cabinet can directly blow the secondary coil; the wind entering from the first air inlet can pass through the primary coil and the secondary coil and then flows out of the transformer cabinet from the first air outlet, and the wind entering from the second air inlet can sequentially pass through the power units and the secondary coil and then flows out of the transformer cabinet from the first air outlet. The converter cabinet body and the converter of this scheme can reduce the requirement of converter to the fan performance.)
