Abstract: A three-phase non-linear transformer is cooled by first (30) and second fans (40). The first fan (30) is attached to the first core clamps (12) of the transformer using a first mounting structure (15). The second fan (40) is attached to the second core clamps (24) of the transformer using a second mounting structure (17). The first fan is positioned first so that air is directed toward a central passage of the core. The second fan is positioned so that air is drawn through the central passage of the core. The first fan circulates air through a central passage in the transformer core and channels that exist between adjacent coil assemblies. The second fan draws air through the central passage and channels and further expels the air into the surrounding environment. The first and second fans are controlled by a control panel through which they are run automatically or manually.

Abstract translation: 三相非线性变压器由第一（30）和第二风扇（40）冷却。 第一风扇（30）使用第一安装结构（15）附接到变压器的第一芯夹（12）。 第二风扇（40）使用第二安装结构（17）附接到变压器的第二芯夹（24）。 首先将第一风扇定位成使得空气被引向芯的中心通道。 第二风扇被定位成使得空气被抽吸通过芯的中心通道。 第一个风扇使空气循环通过变压器铁芯中的中心通道和存在于相邻线圈组件之间的通道。 第二个风扇通过中央通道和通道吸入空气，并进一步将空气排入周围环境。 第一个和第二个风扇由控制面板控制，通过它们自动或手动运行。
