如果電纜機(jī)架內(nèi)部的電纜短路，配電板內(nèi)的電流繼電器會(huì)動(dòng)作，可能會(huì)對(duì)電纜造成較大的損傷。通常是因?yàn)殡娎|質(zhì)量不好。電纜也有可能燒毀，一方也有可能燒毀。這個(gè)問題特別嚴(yán)重。如果電纜或電纜橋架損壞，通常是因?yàn)檫^電流、過載或電纜質(zhì)量差。因此，需要定期檢查和維護(hù)。

If the cable inside the cable rack is short circuited, the current relay in the distribution board will act, which may cause great damage to the cable. Usually because the cable is of poor quality. The cable may also be burned, and one party may also be burned. This problem is particularly serious. If the cable or cable tray is damaged, it is usually due to overcurrent, overload or poor cable quality. Therefore, regular inspection and maintenance are required.

電纜的各相短路。同樣，該故障會(huì)使配電盤的電流繼電器和電壓繼電器工作，電纜在故障點(diǎn)會(huì)嚴(yán)重?fù)p壞。只有一相電纜橋架破損，電流繼電器工作。故障點(diǎn)的損壞很輕微，但很明顯。相電流過大，可能是電纜的質(zhì)量造成的。

Each phase of the cable is short circuited. Similarly, this fault will make the current relay and voltage relay of the distribution board work, and the cable will be seriously damaged at the fault point. Only one phase cable tray is damaged, and the current relay works. The damage at the fault point is slight, but obvious. The large phase current flow may be caused by the quality of the cable.

在工程設(shè)計(jì)中，電纜橋架的布置必須根據(jù)經(jīng)濟(jì)公正性、技術(shù)可行性、運(yùn)行性等因素進(jìn)行綜合比較，確定好的方案，充分滿足施工安裝、維修檢查和電纜敷設(shè)的要求。

In the engineering design, the layout of cable tray must be comprehensively compared according to economic fairness, technical feasibility, operation safety and other factors, and a good scheme must be determined to fully meet the requirements of construction and installation, maintenance and inspection, and cable laying.

橋架、線槽及其吊架用于有侵蝕性的環(huán)境時(shí)，必須用抗侵蝕的剛性材料制造，或者采用防腐處理，防腐處理方法必須滿足工程環(huán)境和耐久性的要求。在要求耐侵蝕功能的地方，或者要求清潔的地方，使用鋁合金制的電纜橋架。

When bridges, trunking and hangers are used in corrosive environment, they must be made of corrosion-resistant rigid materials or treated with anti-corrosion treatment. The anti-corrosion treatment method must meet the requirements of engineering environment and durability. Where corrosion resistance is required, or where cleaning is required, aluminum alloy cable trays shall be used.

增加電纜的總平均布負(fù)荷值，管理機(jī)架的強(qiáng)度。根據(jù)初步確定的橋架形式、規(guī)格及支點(diǎn)間距離，查閱樣品資料，反復(fù)檢查間隔和電纜橋架形式，直滿足負(fù)荷要求。確定電纜橋架的寬度、層數(shù)、支撐點(diǎn)的樣式和間距，以及電纜各層在機(jī)架上的分布。

Increase the total average distribution load of the cable and manage the strength of the rack. According to the preliminarily determined bridge form, specification and distance between fulcrums, consult the sample data, and repeatedly check the spacing and cable bridge form until the load requirements are met. Determine the width of cable tray, the number of layers, the style and spacing of support points, and the distribution of each layer of cable on the rack.

濟(jì)南電纜橋架廠家提醒您，工作環(huán)境受到日照、油、侵蝕性液體、可燃性粉塵等的影響，或者受到屏蔽電磁干擾的電纜布線等環(huán)境要求。請(qǐng)選擇沒有孔的托盤式電纜橋架進(jìn)行使用。

Jinan cable tray manufacturer reminds you that the working environment is affected by sunshine, oil, corrosive liquid, combustible dust, or environmental requirements such as cable wiring shielded from electromagnetic interference. Please select a tray type cable tray without holes for use.
