干式变压器横流式冷却风机 GFD(S)D385-110 干变冷却风机顶吹式 干变风机

　　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).

　　冷却风机使用条件：

　　Service conditions of cooling fan:

　　1、 环境温度应+75℃≥-40℃。

　　1. The ambient temperature shall be + 75 ℃ ≥ - 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。

　　2. The industrial gas passing through the cooling fan is not allowed to have 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。

　　3. Dust and other sundries are not allowed to fall into the fan, so as to avoid fan burning and fan blade fracture.
