Abstract

本实用新型涉及一种变压器风扇轴端防水罩。
该防水罩是在半球形钟罩式的外壳下面平面边 缘处,开有环形凹槽,槽内设有弹性密封圈,外罩底部 有紧固螺钉。将该防水罩安装到变压器风扇轴端,不 仅具有防水作用,而且还能减少噪音。

Description

本实用新型涉及一种变压器风扇轴端防水罩。
通常变压器风扇轴端采用橡胶垫或密封胶防水,往往由于操作不当或经自然风化而失去密封性,使轴端进水,损坏风机造成变压器不能正常运行。
本实用新型的目的在于提供一种变压器风扇轴端防水罩,易于加工制造,对变压器风扇轴端防水有明显的作用,可确保变压器正常运行。
结合附图1,本实用新型是这样实现的。在半球形钟罩式的外壳1的下面平面边缘处,开有环形凹槽,槽内设有弹性密封圈2,外罩底部有紧固螺钉3。
按上述结构制成的变压器风扇轴端防水罩安装在变压器风扇轴端,外壳将风扇轴端全部罩住,其弹性密封圈防止水进入轴端,起到防水作用。同时轴端被防水罩罩住,还能减少噪音。
附图说明:
