双排密集型桥架的哪些优势被放大?

  母线槽的金属封闭外壳能够保护母线免受机械损伤或动物伤害,在配电系统中采用插入单元的安装很安全,外壳可以作为整体接地,接地非常的可靠,而电缆的PVC外壳易受机械和动物损伤,安装电缆时必须先切断电源,如果有错误发生会很危险,特别是电缆要进行现场接地工作,接地的不可靠导致危险性增加。

  The metal enclosed outer shell of the busbar can protect the busbar from mechanical damage or animal damage. The installation of the insertion unit in the distribution system is safe. The shell can be used as a whole grounding, the grounding is very reliable, and the PVC shell of the cable is vulnerable to mechanical and animal damage. The power supply must be cut first when installing the cable, if there is a cable. Mistakes can be very dangerous, especially if the cables are to be grounded, and the unreliability of the grounding will increase the risk.

  母线采用铜排或者铝排,其电流密度大,电阻小,集肤效应小,无须降容使用。电压降小也就意味着能量损耗小,最终节约用户的投资。而对于电缆来讲,由于电缆芯是多股细铜线,其根面积较同电流等级的母线要大。并且其

  Busbar adopts copper bar or aluminum row. Its current density is large, resistance is small, skin effect is small, no need to reduce capacity. A small voltage drop means less energy consumption and ultimately saves user investment. For cable, the core area of the cable core is larger than that of the current grade bus. And its

  密集型母线槽外壳整体兼作PE线,电抗低、保护电路连续性好、安全可靠节约能源。其特点:动热稳定性好、体积小、散热好、温升低、节约空间、压降小、降低能量损耗,适于大功率电流的传输。

  The dense busbar shell is used as the PE line, with low reactance, good continuity of protection circuit, safety and reliability, and energy saving. Its characteristics are good dynamic and thermal stability, small volume, good heat dissipation, low temperature rise, space saving, small pressure drop, and low energy loss, which is suitable for the transmission of high-power current.

  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。

  Dense insulation is connected to the busbar slot. Its moistureproof and heat dissipation effect is poor. In terms of moisture resistance, busbars are susceptible to moisture and seepage during construction, resulting in a decrease in insulation resistance between phases.

  密集型母线槽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。

  The heat dissipation of dense busbar busbar mainly depends on the shell. Because of the compact arrangement between line and line, the heat energy of L2 and L3 phase is slow, and the temperature rise of the busbar groove is high.

  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。

  The dense insulation socket bus bar is restricted by the shell plate, and can only produce a horizontal section not larger than 3m. Due to the small air gap between buses, the busbar can generate strong electric force when the bus passes through a large current, resulting in superposition of the frequency of magnetic oscillation, resulting in excessive noise.
