干式变压器横流式冷却风机 GFD(S)D590-90 干变冷却风机顶吹式 干变风机

　　干式变压器用横流式冷却风机(以下简称：干变冷却风机)主要用于干式变压器冷却增容及电子设备、配电柜、高低、压开关柜等产品的冷却降温等作用。使用该系列冷却风机可提高干式变压器的输出功率40-50%，从而可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，是外厂家普遍采用的经济有效的方式。使其风量更大、噪音更低，进一步提高了风压、降低了能耗，GFD-GFDD系列干变冷却风机的外壳采用了铝合金型材和不锈钢，结构紧凑、安装简便，寿命长，从而为GFD-GFDD系列干变冷却风机长时间在较恶劣环境下平稳运行提供了的保障

　　The cross flow cooling fan for dry-type transformer (hereinafter referred to as dry transformer cooling fan) is mainly used for cooling and capacity increase of dry-type transformer and cooling of electronic equipment, distribution cabinet, high and low voltage switchgear and other products. Using this series of cooling fans can increase the output power of dry-type transformer by 40-50%, so as to improve the bearing capacity of dry-type transformer and prolong the service life of dry-type transformer. It is an economic and effective way widely used by foreign manufacturers. It makes the air volume larger and the noise lower, further improves the air pressure and reduces the energy consumption. The shell of gfd-gfdd series dry variable cooling fan adopts aluminum alloy profile and stainless steel, with compact structure, simple installation and long service life, which provides a guarantee for the stable operation of gfd-gfdd series dry variable cooling fan in harsh environment for a long time
