密集绝缘插接母线槽的叠加状态

  高强度封闭母线槽其工艺制造不受板材限制,济南电缆桥架外壳做成瓦沟形式,使母线机械强度增加,母线水平段可生产13m长。由于外壳做成瓦沟形式,坑沟位置有意将母线分隔固定,母线之间有18mm的间距,线间通风良好,使母线槽的防潮和散热功能有明显的提高,比较适应南方气候。

  The high strength enclosed bus groove is not limited by sheet metal, and the shell of Ji'nan cable bridge is made of tile groove, which increases the mechanical strength of the bus bar, and the horizontal section of the bus can be produced to 13m length. Because the shell is made of tile groove, the location of pit ditch is fixed by bus bar, the distance between the bus bars is 18mm, the ventilation between the lines is good, so that the function of moisture-proof and heat dissipation of the bus slot is obviously improved, which is more suitable for the southern climate.

  空气式插接母线槽由于母线之间接头用铜片软接过渡,在南方天气潮湿,接头之间容易产生氧化,形成接头与母线接触不良,使触头容易发热,故在南方极少使用。并且接头之间体积过大,水平母线段尺寸不一致,外形不够美观。

  Because of the soft copper transition between the bus joints, the air type plug in bus bar is easy to be oxidized in the south, and the contact between the joint and the bus is bad, which makes the contact easy to heat, so it is rarely used in the south. And the size between the joints is too large, the size of the horizontal mother line is not consistent, the appearance is not beautiful.

  密集绝缘插接母线槽其防潮、散热效果较差。在防潮方面,母线在施工时,容易受潮及渗水,造成相间绝缘电阻下降。母线的散热主要靠外壳,由于线与线之间紧凑排列安装,L2、L3相热能散发缓慢,形成母线槽温升偏高。

  Dense insulated plug-in busbar has poor moisture-proof and heat dissipation effects. In the aspect of moisture proof, the busbar is easy to damp and seep during construction, resulting in the decrease of interphase insulation resistance. The heat dissipation of the bus is mainly due to the shell, because of the compact arrangement between the line and the line, the heat dissipation of L2 and L3 phase is slow, and the temperature rise of the busbar is higher.

  密集绝缘插接母线槽受外壳板材限制,只能生产不大于3m的水平段。由于母线相间气隙小,母线通过大电流时,产生强大的电动力,使磁振荡频率形成叠加状态,造成过大的噪声。

  Dense insulated plug-in busbar is limited by shell plate and can only produce horizontal section less than 3m. Because of the small air gap between the bus bars, the bus generates strong electric force when passing through the large current, which makes the magnetic oscillation frequency superposition, causing excessive noise.

  插接式母线槽属树干式系统,具有体积小、结构紧凑、运行可靠、传输电流大、便于分接馈电、维护方便、能耗小、动热稳定性好等优点,在高层建筑中得到广泛应用。

  Plug type busbar is a trunk type system, which has the advantages of small size, compact structure, reliable operation, high transmission current, easy to tap and feed, convenient maintenance, small energy consumption, good dynamic thermal stability and so on. It has been widely used in high-rise buildings.
