产品概述:
GFDD系列顶吹式干式变压器用横流式冷却风机(下称:干变横流冷却风机)主要用于干式变压器冷却增容,及电子设备、配电柜、高低压开关柜等强迫送风冷却。干式变压器配上本风机散热后,可增容40~50%运行,从而大大提高干式变压器的承载能力,并延长了干式变压器的使用寿命,是国内外厂家普遍采用的最经济有效的方式。
本产品严格按JB/T8971-1999《干式变压器用横流式冷却风机》设计生产。电机定、转子铁芯采用优质冷轧硅钢片;低噪音轴承;叶轮采用铝合金表面电泳处理,再通过精细的动平衡调校;左右端板采用不锈钢板冲压成型,进风板、出风板和导风板采用铝合金型材搭扣组合;整个风机结构合理,造型美观,具有风量大、噪声小、温升低、寿命长、运行平稳、安装方便等特点。
工作原理:
该系列冷却风机用于干式变压器时,风机置于变压器线圈下部两侧,将冷风直接吹进变压器的线圈高、低压冷却风道,散热效果明显,可保障变压器的正常运行并延长其使用寿命。(风机开、停及变压器的超温报警、超温跳闸等功能有温控装置提供)。
例:风机型号为GFDD470-120A,表示工作电压单相220V、风机总长为470mm,叶轮直径为120mm,电机安装在右侧的顶吹式干式变压器用横流式冷却风机。
