高强度封闭母线槽知识

    密集母线槽,高强度封闭母线槽(CFW)

    该工艺不受板材的限制,外壳做成华夫饼状,提高了母线的机械强度,母线的水平截面可达13m,由于外壳的盘绕,凹槽的位置被有意分开固定,母线之间的距离为18mm。线路间通风良好,明显提高了母线槽的防潮散热功能,更适合华南地区的气候;线路间有一定的空隙,会引起导线温度的升降,从而提高了过载能力,降低了磁振荡噪声。但其杂散电流和电感电抗远大于密集型母线,因此其导电杆截面必须大于密集型绝缘插入式母线截面。

    由于总线之间的连接器和铜的软结合,中国南方地区的天气潮湿,连接器容易氧化,这使得连接器和总线之间的接触不良,并使接触点易于加热,因此在中国南方地区很少使用。节点间体积过大,水平母线截面尺寸不一致,外形不美观。

    其含水量和散热效果较差。在防潮方面,母线在施工过程中容易受到潮湿和水的影响,导致相间绝缘电阻降低。客车的散热主要取决于外壳。由于导线排列紧凑,L2和L3相的热能分布缓慢,母线槽温升很高。密集绝缘插入式母线只能产生不超过3m的水平段,受外板限制。由于母线间气隙小,当母线通过大电流时,会产生强大的电力,导致磁振荡频率叠加,产生过大的噪声。插入式母线槽是一种干线系统,具有体积小、结构紧凑、运行可靠、传输电流大、分接馈电方便、维护方便、能耗低、动态热稳定性好等优点
