苏博滑触线为您讲解电缆与母线槽应用比较

Su Bo sliding contact line for you to explain the application of comparative cable and bus groove

1、母线槽分接方便：所谓插接式母线槽，就是它利用插接的方式把主干线的电源分接到支线去，因此分接十分方便。
1, bus duct tap is convenient: the so-called plug-in busbar, is it the plug the power line from branch to branch, so the tap is very convenient.
      预制分支电缆其缺点是要向工厂定制；其分支连接方式采用开口的“C"型抱箍，时间一久，能否保证紧箍力？加上每一个分支头的价格不菲，因此预制分支电缆至今应用面仍不广。任何一个楼面需要切断电源，母线槽无须断电，只要在空载的情况下，取下母线槽的插接箱即可。但要切断预制分支电缆的分支电源，在带电的情况下操作是十分危险的。
Prefabricated branch cable its shortcoming is to custom factory; its branches are connected with the opening of the "C" type hoop, a long time, can guarantee the confining stress? With every branch head is expensive, so the prefabricated branch cable has still not widely used. Any of a floor to cut off the power supply, busbar without power, as long as under no load, remove the busbar inserting box. But to branch off the power of prefabricated branch cable, is very dangerous operation in a live condition.
      2、母线槽过载能力强：母线槽过载能力强，取决于它用的绝缘材料工作温度高，母线槽用的绝缘材料过支采用工作温度为105℃的材料，现已开发出工作温度为140℃以上的辐射交联阻燃缠绕带（PER）和辐射交联聚烃热收缩管。而电缆所用的绝缘材料常期工作温度一般为95℃和105℃，因此母线槽的过载能力远远大于电缆。
2, strong overload capacity: busbar busbar strong overload capacity, it depends on the insulating material for high working temperature, insulation material for busbar through the support the working temperature is 105 ℃ material, has developed a working temperature for radiation cross-linking flame-retardant above 140 ℃ wrapping tape (PER) and radiation crosslinking of polyethylene hydrocarbon heat shrinkable tube. The insulating materials often used in cable temperature is 95 ℃ and 105 ℃, therefore the overload capacity is far greater than the cable bus duct.
      3、母线槽能防止过载失火：2000年8月27日，多灾多难的俄罗斯的莫斯科奥斯坦金诺电视塔——*二、欧洲*高楼燃起冲天大火。其原因是电缆过载引起的；宝钢三只转炉停产，也是电缆失火引起。
3, the busway can prevent the overload of fire: August 27, 2000 be dogged by bad luck, the Russian Moscow Ostankino tower -- the first high-rise world, second in Europe, into the fire. The reason is that the cable overload; Baosteel three converter production, but also caused by cable fire.
      普通电缆的绝缘层和外皮会燃烧，阻燃电缆在火焰下也会燃烧，只有在火焰离开后才不燃烧，耐火电缆不会燃烧，但价格昂贵，只有消防等不准停电的电源才用耐火电缆。
The insulating layer and the skin will burn the common cable, flame retardant cable will burn in the fire, only in the flame out after not burning, fire will not burn, but the price is expensive, the power only fire are not allowed to cut with fire-resistant cable.
      母线槽外壳是钢制的，不会燃烧，即使铜排的绝缘材料发生燃烧，火苗也不会窜到母线槽外面。
A casing is made of steel, not combustion, even if the insulation copper combustion, flame will not be outside channeling to busbar.
      4、母线槽散热性能好：电缆的绝缘材料（芯线绝缘和外皮绝缘）既是绝缘材料，又是隔热材料，因此电力电缆在桥架内敷设时，zui多允许敷设2层，其原因日考虑散热。
4, the busway good heat dissipation performance: insulation material of cable (wire insulation and sheath insulation) is an insulating material, and heat insulation material, so the power cable in bridge in laying, the maximum allowed laying of 2 layer, its reason, considering the heat.
      母线槽利用空气传导散热，并通过紧密接触的钢制外壳，把热量散发出去，因此它的散热性能和电缆相比，电缆散热性能可见一斑了。
Busbar using air heat conduction, and the steel shell close contact, radiates the heat, compared it radiating performance and heat dissipation performance of cable, cable remarkable.
      5、母线槽维护方便：母线槽几乎不必维护，日常维护通常是测量外壳和穿芯螺栓的温升、进线箱的接头温升等，穿芯螺栓若采用4.8级，则需要定期紧固，若采用8.8级的高强螺栓则不必定期坚固。
Easy maintenance: 5, busbar busbar practically no maintenance, routine maintenance is usually the inlet box up, measuring shell and core through the bolt temperature joint temperature rise, wear the bolt when using 4.8 stages, require regular fastening, if the use of high strength bolts class 8.8 are not regular solid.
