Abstract

本实用新型公开了一种干式变压器线圈，属于电力设备的技术领域。所述的干式变压器线圈，其线圈上设有连续性的气道（1），所述的线圈上半部的气道（1）为大气道，线圈下半部的气道（1）为小气道，本实用新型改变了气道排布方式，线圈上半部采用大气道，下半部采用小气道，此种气道排布符合变压器温度分布规律，同等条件下可使线圈散热效果更佳和减少线圈绕组尺寸，达到节省材料的目的。

Description

干式变压器线圈
技术领域
本实用新型属于电力设备的技术领域，具体是指一种干式变压器线圈。
背景技术
目前，传统用在干式变压器中的连续式线圈的气道分布除首末几段采用大气道外，其余气道均相等，根据变压器温度分布曲线，变压器温度均是自下而上逐渐升高的，且最热点一般是在线圈高度方向的3/4处，传统的连续式线圈，气道的排布不符合温度分布规律，在满足同等温升要求下，造成了材料的浪费。
实用新型内容
本实用新型的目的在于提供一种即利于散热，又节省材料的干式变压器线圈。
为解决上述技术问题，本实用新型采用的技术方案为：干式变压器线圈，其线圈上设有连续性的气道，所述的线圈上半部的气道为大气道，线圈下半部的气道为小气道。
由于采用了上述的结构，本实用新型改变了气道排布方式，线圈上半部采用大气道，下半部采用小气道。此种气道排布符合变压器温度分布规律，同等条件下可使线圈散热效果更佳和减少线圈绕组尺寸，达到节省材料的目的。
附图说明
图1是干式变压器线圈的结构示意图。
具体实施方式
下面结合附图对本实用新型的具体实施方式作进一步详细的描述，但并不构成对本实用新型的任何限制。
如图1所示，本实用新型所述的干式变压器线圈，线圈上设有连续性的气道1，本实施例共有40段，39个气道，分段点位置在19～20段之间，上半部的气道1大于下半部气道1。此种气道排布符合变压器温度分布规律，同等条件下可使线圈散热效果更佳。

Claims (1)

1.一种干式变压器线圈，其线圈上设有连续性的气道(1)，其特征在于：所述的线圈上半部的气道(1)为大气道，线圈下半部的气道(1)为小气道。
