产品用途和特点（Product use and characteristics）
FFD系列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。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，可提高干式变压器的输出功率40-50％，从而可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。
FFD series cooling blowers mainly used for dry type transformer cooling capacity and electronic equipment, power distribution cabinet, high and low voltage switch cabinets and other products, cooling effect. For the dry-type transformer, fan are arranged at both sides of the lower part of the transformer coil, cold wind blowing directly into the transformer coil high, low pressure cooling air duct, the radiation effect is obvious, can increase the output power of 40-50% dry type transformer, which can greatly improve the bearing capacity of dry type transformer, dry-type transformer and prolong the service life, is a commonly used at China and abroad manufacturers of the most effective and economic way.
我公司生产的FFD系列干变冷却风机依据行业标准(JB/T8971-1999),通过电脑优化组合设计，使其风量更大、噪音更低，进一步提高了风压、降低了能耗，FFD系列干变冷却风机的外壳采用了优质铝合金型材和不锈钢，结构紧凑、外形美观、安装简便，寿命长，从而为FFD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可靠的保障。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。
Our company produces FFD series of dry cooling fan based on industry standards (JB/T8971-1999), through the computer optimization design, make its volume larger, lower noise, and further improve the wind pressure, reducing energy consumption, FFD series of dry cooling fan shell adopts the high quality aluminum and stainless steel, with compact structure, beautiful appearance, convenient installation, long service life, thus providing a reliable guarantee for the FFD series of dry cooling fan in a harsh environment runs stably in a long time. And the transformer fan on, stop over temperature alarm, over temperature tripping function offered by temperature control device.
冷却风机使用条件（Cooling fan operating conditions）1、 环境温度应75ºC≥-40ºC。（Environmental temperature 75 º C º C ≥ -40）
2、 通过冷却风机的工业气体不允许有强酸、强碱及各种溶液。（Through the industrial gas cooling fan does not allow to have the strong acid, strong alkali and various solutions.）
3、 不允许有沙尘等杂物掉入风机内，以免造成风机烧毁及扇叶断裂。（Dust and debris into the air blower is not permitted, in order to avoid wind machine burned and fan blade fracture.）
安装与维护（Installation and maintenance）1、 安装前应首先检查是否因包装运输造成损坏、变形、如有损坏或变形应修复后安装使用。（Before installation should firstly check for transport packaging damage, deformation, such as damage or deformation should be repaired after installation.）
2、 然后再检查各零件及螺丝是否有松动；叶片与风筒之间是否相碰或移位，若相碰或移位应进行调整后方可安装。（Then check each part and see if the screw is loose; between the blade and the air duct is touching or shift, if encounter or shift should be adjusted before installation.）
3、 冷却风机安装后应进行试机，待风机运行正常后再进行联机使用。（After cooling fan installed and should be for a trial, please wait for the operation of the wind turbine back to normal , then move on to the online use.）
4、 风机长期置放重新使用时，应对风机进行检查试运行若无异常现象，方可联机使用。（Reusing for the fan after long-term placement, please check wind turbine for an trial if no abnormal phenomenon occurs, then can be used in online.
5、风机安装完毕后应将接线合密封，以防接线合渗漏造成短路烧毁电机。（Fan after installation should be sealed to prevent the wiring and leakage caused by short circuit burned motor.）
搬运和存放（Handling and storage）1、 在搬运过程中，要注意轻拿轻放，按照包装箱的标志和要求搬运和放置，切勿倒置和立置。（In the process of handling, we should pay attention to handle gently, carry and placed according to mark packing box and carry requirement, be sure not to place upside down and in the vertical position.）
2、 在搬运过程中应避免强烈冲击和剧烈震动，以防包装葙和产品破损。（In the process of handling should avoid strong shock and vibration, to prevent the packing box and product damage.）
3、风机应存放于透风、干燥没有腐蚀性气体处，避免雨淋和阳光暴晒。（The wind turbine shall be stored in ventilated, dry and no corrosive gas, avoid rain and sun exposure.）
订货须知（ordering instruction）1、 订货时请根据使用要求和变压器的容量及结构形式，参照资料提供的产品型号选型，我公司也可根据您的使用规格进行定制。（Please ordering by operational requirement according to the capacity and structure requirements of transformer, product type selection please refers to information as attached, our company also can be customized according to your specifications.）
