贏下女電纜橋架承載能力的因素有哪些?

電纜橋架在電線電纜安裝過程中支撐著電線電纜。它不僅可以規范電線電纜的安裝,而且對它們有一定的保護作用,使電纜橋架具有一定的承載能力。如果沒有很好的承載能力,那么會影響電纜的實用性。那么電纜橋架承載能力受哪三個因素的影響呢?
The cable tray supports the wires and cables during the installation of wires and cables. It can not only regulate the installation of wires and cables, but also protect them, so that the cable bridge has a certain bearing capacity. If there is no good bearing capacity, it will affect the practicability of the cable. So what three factors affect the bearing capacity of cable tray?
電纜橋架承載能力的影響因素:
Factors affecting the bearing capacity of cable tray:
1、動載荷是指在電纜橋架安裝和維護過程中施工和維護人員的重量。對于輕型索橋,一般不考慮動荷載,即不允許人站在橋上。如果需要考慮人站立,跨度應適當縮短。
1. Dynamic load refers to the weight of construction and maintenance personnel during the installation and maintenance of cable tray. For light cable bridges, dynamic load is generally not considered, that is, people are not allowed to stand on the bridge. If people need to stand, the span should be shortened appropriately.
2、靜載荷是指放置在電纜橋架中的電纜種類、電纜數量、每根電纜的外徑、重量/單位長度,并根據不同的電纜走線路線進行統計。
2. Static load refers to the type and quantity of cables placed in the cable tray, the outer diameter, weight / unit length of each cable, and statistics shall be made according to different cable routes.
3、附加載荷僅指冰、雪、風和外界電磁力形成的載荷。它與安裝地點的自然氣象條件和裝載體的性質有關。在設計中要根據各種條件進行計算。
3. The additional load only refers to the load formed by ice, snow, wind and external electromagnetic force. It is related to the natural meteorological conditions of the installation site and the nature of the loading carrier. The calculation shall be carried out according to various conditions in the design.
電纜橋架采用薄鋼板沖壓而成,承載能力有限,會因橋架過載而引起變形,不僅影響橋架美觀,而且影響電纜的運行。通常情況下,電纜橋架的承載能力由其負載特性曲線表示。從負載曲線可以看出,負載能力與托盤的大小和支撐距離有關。對應相同距離的支撐和彎曲凸變形。橫向高度大承載能力大在承載能力相同的情況下,相同規格的電纜橋架支撐距離小,彎曲變形小。
The cable tray is stamped with thin steel plate with limited bearing capacity, which will cause deformation due to overload of the cable tray, which will not only affect the beauty of the cable tray, but also affect the operation of the cable. Generally, the bearing capacity of cable tray is represented by its load characteristic curve. It can be seen from the load curve that the load capacity is related to the size and support distance of the tray. Support and bending convex deformation corresponding to the same distance. The transverse height is large and the bearing capacity is large. Under the condition of the same bearing capacity, the supporting distance of the cable tray of the same specification is small and the bending deformation is small.
橋架可以獨立安裝。當然,它們也可以安裝在各種建筑物和管架上。它們具有許多特點和優點,因為它們不僅可以體現簡單的結構和形狀。既美觀,又可以發揮配置靈活、維護方便等特點。
The bridge can be installed independently. Of course, they can also be installed on various buildings and pipe racks. They have many characteristics and advantages because they can not only reflect simple structure and shape. It is not only beautiful, but also has the characteristics of flexible configuration and convenient maintenance.
因此,要保證電纜橋架的承載能力,材料很重要,但也需要好的設計和好的材料,兩方面同時協調,才能保證產品的質量。所以一定要注意電纜橋架的承載能力,在保證電纜橋架承載能力的同時,也需要前期的設計和后續的材料保證。
Therefore, to ensure the bearing capacity of the cable tray, the material is very important, but it also needs good design and good materials. The two aspects should be coordinated at the same time in order to ensure the quality of the product. Therefore, we must pay attention to the bearing capacity of the cable bridge. While ensuring the bearing capacity of the cable bridge, we also need the early design and subsequent material guarantee.
