母线槽，是一种由铜、铝母线柱组成的闭合金属装置，用于为分散系统中的各部件分配较大的功率。家庭用电低压传输主干工程中电线电缆的替代日益增多。那么母线槽到底是干什么用的？下面济南电缆桥架小编为您解答。

Busduct is a closed metal device composed of copper and aluminum bus bars, which is used to distribute large power to various components in the distributed system. The substitution of wires and cables in the low-voltage transmission backbone project of household electricity is increasing. What is the bus duct used for? Here is a brief compilation of Jinan cable tray.

伴随着现代工程设施和设备的出现，各行各业的用电量迅速增长，特别是大量高层建筑和大型厂房车间的出现，传统的以输电导线形式的电缆在大电流输送系统中已经不能满足要求，同时采用多路电缆给现场安装施工连接带来了不便。母线槽插接是一种新型的配电导线。

With the emergence of modern engineering facilities and equipment, the power consumption of all walks of life is growing rapidly, especially the emergence of a large number of high-rise buildings and large workshops. The traditional cables in the form of transmission conductors can no longer meet the requirements in the large current transmission system. At the same time, the use of multi-channel cables brings inconvenience to the on-site installation, construction and connection. Bus duct connection is a new type of distribution conductor.

在大电流传输下，与传统电缆相比，它的优点得到了充分的体现，同时由于采用了新技术、新工艺，母线槽两端连接部分及分线口插接部分的接触电阻和温升大大降低，母线槽内采用了优绝缘材料，提高了母线槽的可靠性，使整个系统更加完善。

Under the condition of large current transmission, compared with traditional cables, its advantages have been fully reflected. At the same time, due to the adoption of new technology and new process, the contact resistance and temperature rise of the connection parts at both ends of the bus duct and the plug-in part of the branch port have been greatly reduced. The bus duct is made of superior insulating materials, which improves the safety and reliability of the bus duct and makes the whole system more perfect.

母线槽一般由始端母线槽、直通母线槽(分带式和非带式)、L型垂直(水平)弯通母线、Z型垂直(水平)偏置母线槽、T型垂直(水平)三通母线槽、X型垂直(水平)四通母线、变容母线槽、膨胀母线槽、端端头、端端接线箱、插接箱、母线槽有关附件及紧固装置等组成。

The bus duct is generally composed of starting bus duct, straight bus duct (zonal and non zonal), L-shaped vertical (horizontal) elbow bus duct, Z-shaped vertical (horizontal) offset bus duct, T-shaped vertical (horizontal) three-way bus duct, X-shaped vertical (horizontal) four-way bus duct, variable capacity bus duct, expansion bus duct, end terminal, end terminal box, plug box, bus duct related accessories and fasteners.

按照绝缘方式，母线槽可分为空气式插接母线槽、绝缘密度高的插接母线槽和高强的插接母线槽。根据其结构和用途，可分为密集绝缘、空气绝缘、空气附加绝缘、耐火绝缘、树脂绝缘和滑触绝缘的母线槽；根据其外壳材料可分为钢壳、铝壳和钢铝混合壳的母线槽。

According to the insulation mode, the bus duct can be divided into air type plug-in bus duct, plug-in bus duct with high insulation density and high-strength plug-in bus duct. According to its structure and use, it can be divided into bus ducts with dense insulation, air insulation, air additional insulation, fire-resistant insulation, resin insulation and sliding contact insulation; According to the shell material, it can be divided into steel shell, aluminum shell and steel aluminum mixed shell bus duct.

特点

characteristic

因为母线槽是以铜排或铝板为导体，电流容量大，且电气及机械性能良好，另外采用金属槽为外壳，故具有燃烧性强，可靠，使用寿命长，相对于传统的配电或比较，设备所占面积大大减少，且外观美观，对大型建筑的施工和配电都十分有利，概括起来，母线槽具有以下特点。

Because the bus duct uses copper bar or aluminum plate as the conductor, it has large current capacity, good electrical and mechanical properties, and uses metal trough as the shell, so it has strong combustibility, safety and reliability, and long service life. Compared with traditional power distribution or comparison, the equipment occupies a much smaller area, and has a beautiful appearance, which is very beneficial to the construction and power distribution of large buildings. To sum up, the bus duct has the following characteristics.

1、是电流的容量可以很大；

9. The connection is very simple (just like water pipe connection, a section of water pipe is connected into a system through a tee, an elbow and other joints).

10、施工和检验简便；

10. Simple construction and inspection;

11、具有现代审美情趣。

11. It has modern aesthetic taste.

就经济性而言，母线槽本身与电缆相比，稍高一些，但与包括配线用的各种附件和整个电力系统相比，母线槽的使用，尤其是在有大电流容量时，建造成本要低得多。更多相关内容的了解就来我们网站http://www.sddlqj.cn咨询吧！

In terms of economy, the bus duct itself is slightly more expensive than the cable, but compared with various accessories including wiring and the entire power system, the construction cost of bus duct is much lower, especially when there is large current capacity.
