干式变压器横流式冷却风机 GFD(S)760-120 干变冷却风机侧吹式 干变风机

　　1、冷却风机一般安装在干式变压器下夹件旁边，将底下及外面的冷空气吹向干式变压器的线圈内，使干式变压器能充分冷却。安装时应根据冷却风机的出风角度（与水平夹角约为135°）及出风口位置，使风机的出风能顺利地进入干式变压器的高低压线圈间的风道，从而使散热效果。

　　1. The cooling fan is generally installed next to the lower clamp of the dry-type transformer to blow the cold air below and outside into the coil of the dry-type transformer, so that the dry-type transformer can be fully cooled. During installation, according to the air outlet angle of the cooling fan (the included angle with the horizontal is about 135 °) and the position of the air outlet, the air outlet of the fan can smoothly enter the air duct between the high and low voltage coils of the dry-type transformer, so as to improve the heat dissipation effect.

　　2、 该冷却风机安装一般采用下底脚支撑式，这种安装方式是将底架做成一框架并固定在夹件或底脚上，然后将风机安装在框架上。为了减小风机的振动，安装时应在底脚下垫上橡胶块。

　　2. The cooling fan is generally installed with lower foot support. This installation method is to make the underframe into a frame and fix it on the clamp or foot, and then install the fan on the frame. In order to reduce the vibration of the fan, rubber blocks shall be padded under the feet during installation.

　　3、 为了不影响冷却风机的出风量，安装时其进风口（指外侧面）应与封闭的障碍物保持一定的距离（一般不小于10cm），使风机的进风顺畅，建议风机进风口附近的外壳应开有通风孔。

　　3. In order not to affect the air outlet of the cooling fan, the air inlet (referring to the outer side) shall be kept at a certain distance (generally not less than 10cm) from the closed obstacles during installation to make the air inlet of the fan smooth. It is recommended that the shell near the air inlet of the fan shall be provided with ventilation holes.
