干式变压器横流式冷却风机 GFD(S)780-110 干变冷却风机侧吹式 干变风机

　　干式变压器风机严格按JB/T8971-2013《干式变压器用横流式冷却风机》设计生产。电机定、转子铁芯采用一流冷轧硅钢片;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。

　　The fan of dry-type transformer is designed and produced in strict accordance with JB / t8971-2013 cross flow cooling fan for dry-type transformer. The stator and rotor cores of the motor are made of high-quality cold-rolled silicon steel sheets; Low noise bearing; The impeller adopts aluminum alloy surface electrophoresis treatment, and then fine dynamic balance adjustment; The left and right end plates are formed by stamping stainless steel plates, and the air inlet plate, air outlet plate and air guide plate are made of aluminum alloy profile buckle combination; The whole fan has reasonable structure, beautiful appearance, large air volume, low noise, low temperature rise, long service life, stable operation, convenient installation and so on.

　　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)。

　　Working principle when this series of cooling fans are used for dry-type transformer, the fans are placed on both sides of the lower part of the transformer coil to directly blow the cold air into the high and low-voltage cooling air ducts of the transformer coil. The heat dissipation effect is obvious, which can ensure the normal operation of the transformer and prolong its service life. (the functions of fan start and stop, overtemperature alarm and overtemperature trip of transformer are provided by temperature control device).
