高压电网用分割导体
本技术涉及电能传输材料,具体涉及高压电网用分割导体。
技术介绍
由于集肤效应的存在,导体中的电流密度并不均匀分布,而是沿电缆导体径向自表面到中心逐渐减小,当导体直径增大到一定程度时,集肤效应严重,严重阻碍了导体的传输容量,为此,有人提出了分割导体以解决此技术问题。但现有技术中的分割导体在实际使用中发现,导体产生损耗而发热的有效电阻影响较大,各分割股块中心空隙尚未有效利用,散热性能差。
技术实现思路
本技术针对以上问题,提供了散热性能好、结构精巧并且由于发热产生的有效电阻小的高压电网用分割导体。本技术的技术方案是:包括集束管和分隔件,所述分隔件包括铝芯和连接在铝芯表面的若干径向分隔腔,若干所述径向分隔腔将集束管分为若干等截面面积的腔体,若干所述径向分隔腔外侧壁上覆有皱纹绝缘纸层,若干所述径向分隔腔中填充有导热介质材料,所述铝芯沿轴向设在集束管内部,所述铝芯铅垂向的上表面沿轴向开有散热槽、且散热槽槽底向下开设有若干导热通道,若干所述导热通道均向铝芯同一端倾斜。所述导热介质材料为导热硅脂。所述若干导热通道与铝芯轴向所呈角度在35°至55°之间。本技术实际工作 ...
