发明内容
本实用新型的目的是克服现有技术的不足之处,提供一种干式变压器低压线圈。
本实用新型的干式变压器低压线圈,包括铜箔、端绝缘、层绝缘、气道撑条和固定连接在铜箔线圈上的内出线铜排及外出线铜排,所说的内出线铜排和外出线铜排表面设有副绝缘层。
本实用新型的干式变压器低压线圈具有如下技术效果:通过在内、外出线铜排上增加副绝缘层,使得绝缘强度增加,并且减少了绝缘距离。
附图说明
图1是本实用新型的干式变压器低压线圈的正面结构示意图。
其中,1为内出线铜排,2为外出线铜排,3-1为端绝缘,3-2为层绝缘,4为副绝缘层,5为铜箔线圈。
具体实施方式
下面结合附图和具体实施方式来对本实用新型作进一步地详细说明。
如图1所示,本实用新型的干式变压器低压线圈,包括铜箔线圈5、端绝缘3-1、层绝缘3-2、气道撑条和固定连接在铜箔线圈5上的内出线铜排1及外出线铜排2,内出线铜排1和外出线铜排2表面设有副绝缘层4。
