封闭母线桥，主要是由母线的导体以及支持绝缘子和一个防护屏蔽外壳组成的，这三个部分都比较重要，而且采用了重要的结构，比如导体以及外壳采用了铝管结构，另外封闭母线采用了微正压的装置，防止绝缘子受潮，大大提升了可靠性。下面山东电缆桥架厂家为您讲解更多事项：

The enclosed busbar bridge is mainly composed of the conductors of the busbar, supporting insulators, and a protective shielding shell. These three parts are relatively important and adopt important structures, such as the use of aluminum tube structure for the conductors and shell. In addition, the enclosed busbar adopts a micro positive pressure device to prevent the insulators from getting damp, greatly improving safety and reliability. Next, the manufacturer of cable tray in Shandong will explain more things to you:

1.了解封闭母线桥相关知识

1. Understand the relevant knowledge of enclosed busbar bridges

这一个母线适用于比较特殊的发电机，因为这种出现回路以及常用分支回路，是一个大电流的输出装置。这一个特点有许多，外壳都是采用了铝板，所以它的各方面都有一些特点。

Firstly, this busbar is suitable for special generators, as this type of circuit and commonly used branch circuit is a high current output device. There are many characteristics of this, and the outer shell is made of aluminum plate, so it has some characteristics in all aspects.

减少了接地故障，避免的短路情况，另外还可以外界的潮气以及灰尘，另外还有一些，不封闭导致的闭路情况，各种短路都可以被杜绝，还是一个比较不错的母线结构。

It reduces grounding faults and avoids short circuits. In addition, it can eliminate external moisture and dust. In addition, there are also some closed circuit situations caused by non sealing, and various short circuits can be eliminated, making it a relatively good bus structure.

2.封闭母线桥优势

2. Advantages of enclosed busbar bridge

这种母线桥很多人不太了解，了钢结构发热的情况，解决了各方面的感应问题减少了短路，另外，使得导体的短路电动力大大降低，看得出来这方面的优势还是挺大的，所以越来越多的用户都选择了封闭母线桥，就是因为这方面的原因。

Many people are not familiar with this type of busbar bridge, which eliminates the heating problem of the steel structure, solves various induction problems, reduces short circuits, and greatly reduces the short-circuit electric force of the conductor. It can be seen that this advantage is quite significant, so more and more users are choosing enclosed busbar bridges because of this reason.
