Abstract

阶梯状组合换位导线，与换流变压器配套使用。其结构是将两根相同的换位导线平行排列用具有耐热性的绝缘纸组合绕包，绕包后将左侧或右侧一根断开移到右侧或左侧搭接后再统包，形成多级阶梯状，并且在相邻两根换位导线之间夹有绝缘纸板。本实用新型由于其结构合理，增加了变压器线圈端部的机械强度，解决线圈首端几段线电压梯度陡降问题，使线圈端部电压分布均匀，起到电容保护作用，避免因外部雷电冲击、操作合闸等造成首端电压瞬间增高几十倍损坏匝绝缘，造成变压器损坏的技术难题。具有送电网络损耗小及送电网络成本低的特点。

Description

阶梯状组合换位导线
技术领域：本实用新型涉及一种组合换位导线，特别是一种阶梯状组合换位导线，与换流变压器配套使用。
背景技术：电力输送中常采用交流输送的方式，采用这种方式送电存在着网络损耗较大，输送成本较高的缺点。随着技术的进步，目前电力输送逐渐由交流转变为直流送电，这样可以克服交流送电网络损耗大及输送网络成本高的缺点，但也同时对与换流变压器配套使用的组合换位导线提出了新的更高的技术要求。
发明内容：本实用新型的目的是针对上述现有技术的不足，而提供一种结构合理的新型阶梯状组合换位导线。为实现上述目的，本实用新型采用下述技术方案：阶梯状组合换位导线，是由两根相同的换位导线按要求的绝缘厚度，组合统包一定的长度后，将左侧或右侧一根断开移到右侧或左侧搭接一定长度后按要求统包，形成多级阶梯状，并且在相邻两根换位导线之间夹有绝缘纸板，且所夹绝缘纸板的厚度在每个阶梯之间有所不同。
本实用新型由于其结构合理，增加了变压器线圈端部的机械强度，解决线圈首端几段线电压梯度陡降问题，使线圈端部电压分布均匀，起到电容保护作用，避免因外部雷电冲击、操作合闸等造成首端电压瞬间增高几十倍损坏匝绝缘，造成变压器损坏的技术难题。具有送电网络损耗小及送电网络成本低的特点。

图2是图1中A-A剖面图。
具体实施方式：
实施例一
参照图1、2，阶梯状组合换位导线，包括单根换位导线1。其具体结构是：将两根相同的换位导线1平行排列并用具有耐热性的绝缘纸组合绕包，绕包后将左侧或右侧一根断开移到右侧或左侧搭接后再统包，形成多级阶梯状，并且在相邻两根换位导线之间夹有绝缘纸板3。
所述单根换位导线1外包覆绝缘层6，相邻两根换位导线1外面包覆绕包绝缘层2，并在换位导线1的搭接处包覆统包保护绝缘层4；
所述单根换位导线1由多根漆包金属扁线5构成，漆包金属扁线5外包覆绝缘层7；
所述漆包金属扁线5采用电工用铜、铝及其合金扁线。
