蘇博滑觸線為您講解電纜與母線槽應用比較

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

1、母線槽分接方便：所謂插接式母線槽，就是它利用插接的方式把主干線的電源分接到支線去，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.
      預制分支電纜其缺點是要向工廠定制；其分支連接方式采用開口的“C"型抱箍，時間一久，能否保證緊箍力？加上每一個分支頭的價格不菲，因此預制分支電纜至今應用面仍不廣。任何一個樓面需要切斷電源，母線槽無須斷電，只要在空載的情況下，取下母線槽的插接箱即可。但要切斷預制分支電纜的分支電源，在帶電的情況下操作是十分危險的。
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、母線槽過載能力強：母線槽過載能力強，取決于它用的絕緣材料工作溫度高，母線槽用的絕緣材料過支采用工作溫度為105℃的材料，現已開發出工作溫度為140℃以上的輻射交聯阻燃纏繞帶（PER）和輻射交聯聚烴熱收縮管。而電纜所用的絕緣材料常期工作溫度一般為95℃和105℃，因此母線槽的過載能力遠遠大于電纜。
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、母線槽能防止過載失火：2000年8月27日，多災多難的俄羅斯的莫斯科奧斯坦金諾電視塔——*二、歐洲*高樓燃起沖天大火。其原因是電纜過載引起的；寶鋼三只轉爐停產，也是電纜失火引起。
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.
      普通電纜的絕緣層和外皮會燃燒，阻燃電纜在火焰下也會燃燒，只有在火焰離開后才不燃燒，耐火電纜不會燃燒，但價格昂貴，只有消防等不準停電的電源才用耐火電纜。
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.
      母線槽外殼是鋼制的，不會燃燒，即使銅排的絕緣材料發生燃燒，火苗也不會竄到母線槽外面。
A casing is made of steel, not combustion, even if the insulation copper combustion, flame will not be outside channeling to busbar.
      4、母線槽散熱性能好：電纜的絕緣材料（芯線絕緣和外皮絕緣）既是絕緣材料，又是隔熱材料，因此電力電纜在橋架內敷設時，zui多允許敷設2層，其原因日考慮散熱。
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.
      母線槽利用空氣傳導散熱，并通過緊密接觸的鋼制外殼，把熱量散發出去，因此它的散熱性能和電纜相比，電纜散熱性能可見一斑了。
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、母線槽維護方便：母線槽幾乎不必維護，日常維護通常是測量外殼和穿芯螺栓的溫升、進線箱的接頭溫升等，穿芯螺栓若采用4.8級，則需要定期緊固，若采用8.8級的高強螺栓則不必定期堅固。
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.
