具体实施方式
下面将结合本发明实施例，对本发明实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅仅是本发明一部分实施例，而不是全部的实施例。基于本发明中的实施例，本领域普通技术人员在没有作出创造性劳动前提下所获得的所有其他实施例，都涉及本发明保护的范围。
本实施例提出了一种单相多绕组变压器的低压连接引线结构，
如图1-6所示，
包括油箱1，油箱1内设有多个单相变压器2，油箱1的侧壁上还设有多个插拔式套管3，插拔式套管3通过连接引线4与单相变压器2的线圈连接点连接，还包括：
导线支架5，设置在油箱1内，导线支架5包括多个沿第一方向设置的和多个沿第二方向设置的安装杆51，安装杆51上均设有多个导线夹6。
上述的第一方向指水平方向，第二方向指竖直方向，多个安装杆51按需要水平设置或竖直设置，通过在安装杆51上设置的导线夹6夹住连接引线4，将连接引线4分层布置，确定连接引线4的走向，方便连接引线4连接插拔式套管3，同时使连接引线4布置更加简单、方便，连接引线4布局更加整齐、美观，方便后期维护。
连接引线4与单相变压器2的线圈连接点采用压接形式。
连接引线4可以采用电缆，电缆连接引线4与单相变压器2的线圈连接点采用压接的方式连接，无明火作用，更加安全，连接简单方便。
还包括转接铜排，用于连接连接引线4与插拔式套管3。
通过转接铜排连接连接引线4与插拔式套管3，方便安装。
还包括：
升高座7，为台阶形，设置在油箱1的一侧，升高座7的内部与油箱1内部连通，插拔式套管3设置在升高座7的台阶上。
在油箱1的一侧设置台阶形的升高座7，在升高座7的台阶上设置插拔式套管3，可以避免在同一个平面上布置插拔式套管3，插拔式套管3数量过多导致排列过于紧凑，安装不方便的问题。
还包括：
盖板，升高座7的顶部开设有人孔，盖板盖在人孔上，盖板上设有安装位，用于安装充油套管8，进行变压器试验；
进行变压器试验时，连接引线4连接充油套管8。
在升高座7顶部开设人孔，方便变压器试验和工人接线操作，在需要进行变压器试验时在盖板上安装充油套管8，并将连接引线4连接至充油套管8，方便进行变压器试验。
导线支架5还包括：
沿第二方向设置在油箱1内的和沿第一方向设置在油箱1内的滑杆52，安装杆51沿滑杆52滑动。
安装杆51可以沿着滑杆52滑动，可以很方便的调整导线夹6的位置，使导线支架5使用更灵活，可以适应不同的连接引线4布局。
导线支架5还包括：
螺杆53，转动设置在油箱1内，沿滑杆52的长度方向设置；
螺块54，与螺杆53啮合，其上设有第一孔；
安装套55，设置在安装杆51上，套设在螺块54上，其上设有第二孔；
插杆56，插在第一孔和第二孔内。
在需要调整某个安装杆51的位置时，可以用对应的插杆56插进对应的安装杆51上的安装套55上的第二孔和螺块54上的第一孔内，使安装套55和螺块54可以同步运动，而其他安装杆51对应的插管则拔出，使安装套55可以相对螺块54转动；需要调整的安装杆51对应的螺块54被限制了转动的自由度，因此在转动螺杆53时会进行平移带动安装杆51平移， 而其他安装杆51对应的螺块54则会随着螺杆53转动，无法带动安装杆51移动；每一个安装杆51均可以单独调整，使用方便。
导线夹6包括：
底座61，设置在安装杆51上，底座61上设有第一弧形槽；
罩板62，设置在底座61上；
压块63，滑动设置在罩板62上，其上设有第二弧形槽；
顶丝64，设置在罩板62上，用于在底座61与压块63间夹有连接引线4时顶紧压块63。
在使用导线夹6夹紧连接引线4时，将连接引线4闯过罩板62，时连接引线4被夹在底座61上的第一弧形槽和压块63上的第二弧形槽之间，调整顶丝64将压块63顶紧，即可完成导线的夹紧，使用方便，夹紧稳定。
底座61转动设置在安装杆51上，底座61的转动轴垂直安装杆51的长度方向。
导线夹6的底座61可以转动，在进行夹线时更加方便连接引线4穿过罩板62，调整连接引线4走向也更加灵活方便。
安装杆51内设有油道57，安装杆51的侧壁上设有多个油孔58，油孔58与油道57连通，油道57用于连通冷却装置。
由于连接引线4数量较多，会产生较大的热量，使连接引线4附近温度升高，在安装杆51上内设有油道57，并通过侧壁的油孔58与油箱1内部连通，并将油道57连通至冷却装置，可以更好的对连接引线4附近散热。
如图7-13所示，
单相变压器2包括，支撑架9、铁芯10和绕组，支撑架9设置在油箱1内，绕组设置在铁芯10上，支撑架9包括上循环管和下循环管，铁芯10设置在上循环管与下循环管之间；
上循环管与下循环管均与油室连通，多个油室内的上循环管连通，多个油室内的下循环管连通；
上循环管与下循环管用于连通冷却装置。
铁芯10安装在上循环管和下循环管之间，冷却装置的进油端和出油端分别连接上循环管和下循环管，通过上循环管道、下循环管道和冷却装置对油室内的油液进行循环冷却，冷却效果更好，而且将支撑铁芯10的安装架与油液循环管道整合，不需要额外布置油液管道，整体结构更加简单。
上循环管和下循环管均由多个管节91拼接而成。
可以通过管节91拼接形成不同大小的支撑架9，以适应不同尺寸的铁芯10。
管节91侧壁上开设有多个开孔911。
在管节91的侧壁上开设开孔911，作为油液进入上循环管和下循环管的通道，也可以设置油管与开孔911连通，并使油管的开口处于油室内温度相对较高的位置，可以优先使高温油液先进入循环，提升冷却效果。
管节91的侧壁上设有拼接槽912，多个管节91拼接完成后，多个管节91上的拼接槽912拼接形成封闭的卡槽92；
支撑架9还包括卡环93，卡环93设置在卡槽92内。
通过多个管节91上的拼接槽912拼接而成封闭的卡槽92，再将卡环93卡在卡槽92内，以此实现多个管节91的拼接，保证管节91拼接的密封性，卡环93可以有多种型号，适应不同数量的管节91的拼接。
在管节91上设置相对的两组拼接槽912，形成两条卡槽92，通过卡环93进行固定，更加稳定。
位于两端的管节91上拼接槽912为单条，在同一端有两个拼接口，位于中间的管节91上的拼接槽912，为两条平行槽，两端均设有拼接口。
管节91为方形管，方便铁芯10的安装，支撑更稳定。
相邻的两个管节91的拼接处分别设有凸起913和凹槽914，凸起913伸进凹槽914内，方便两个管节91拼接时定位，凸起913和凹槽914均不是环形槽，可以避免相邻的两个管节91转动。
位于两端的管节91一端封闭，并设有接头，用于与油管连通。
以上仅为本发明的较佳实施例而已，并不用以限制本发明，凡在本发明的精神和原则之内，所作的任何修改、等同替换、改进等，均应包含在本发明的保护范围之内。
