音响工程一般都有大量的各种类型的线缆,这些线缆都需要预先铺设在预埋的管线里,或者与系统连接后铺设在控制室的某一个位置。下面来了解下音响工程各种线缆的铺设内容吧。
Sound engineering generally has a large number of various types of cables, which need to be laid in the embedded pipeline in advance, or laid at a certain position in the control room after connecting with the system. Now let's learn about the laying of various cables in audio engineering.
铺设前要将各种线缆按照设计要求分类放好线,放线时应该小心进行,尽量一一作好明显的标记,作为安装和检修的查找依据,千万不要将线缆弄乱,同时一定要留下充足的富余量,线缆中间不允许接头,放好线后仔细检查每条线是否有破损或质量低劣的情况,一旦有就应该立即全部更换。
Before laying, all kinds of cables should be placed in accordance with the design requirements. During the setting out, care should be taken to make obvious marks one by one as the basis for installation and maintenance. Do not mess up the cables. At the same time, sufficient surplus must be left. No joints are allowed in the middle of the cables. After placing the cables, carefully check whether each line is damaged or of poor quality. Once there is, it should be replaced immediately.
铺设的线缆须依照设计和布局的位置准确到位;其次,因为线缆的铺设只有一次机会,基本上没有返工的可能,所以铺设时要对照设计图纸,掌握合理的方法进行,不能希望图快而蛮干,否则就可能带来不必要的麻烦。
The laid cables must be in place according to the design and layout; Secondly, because there is only one chance to lay the cable, there is basically no possibility of rework, so when laying, we should compare the design drawings and master a reasonable method. We can't expect the drawing to be fast and reckless, otherwise it may cause unnecessary trouble.
在线缆铺设时要求施工人员相互协调配合,动作和用力要一致均匀,如果遇到转弯、挂碰的时候,一定要小心,协同解决。
During cable laying, the construction personnel are required to coordinate with each other, and the action and force should be consistent and uniform. If there is a turning or hanging collision, be careful and solve it cooperatively.
另外,线缆铺设工作中一项很重要,但又经常被人们忽略的工作是系统保护地线的铺设和信号屏蔽线的铺设,而且由于很少有人对这两个线缆的概念进行清楚的区分,导致许多的工程技术人员也混淆不清,在实际工程施工中发生错误,这就是为什么许多音响系统总是有不掉的噪音,而有些系统的保护地线失去作用,设备外壳带电的原因。
In addition, a very important but often neglected work in cable laying is the laying of system protective ground wire and signal shielding wire. Moreover, because few people clearly distinguish the concepts of these two cables, many professional engineering technicians are also confused, and errors occur in actual engineering construction, which is why many sound systems always have noise that cannot be eliminated, However, the protective ground wire of some systems fails to work, and the equipment shell is electrified.
此外对于
山东音响系统的屏蔽线,在铺设时保护地线一般都须设置,而且应该连接良好,或者直接连接在机柜上,或者通过电源插座与设备本身的地线相通,铺设完毕后逐一检查各设备与地线的导通状况;信号的屏蔽线路铺设需要结合后面的线路连接情况,以及系统的要求和噪音情况而定。
In addition, as for the shielded wire of Shandong professional sound system, the protective ground wire must be set when laying, and it should be well connected, or directly connected to the cabinet, or connected to the ground wire of the equipment itself through the power socket. After laying, check the continuity of each equipment and the ground wire one by one; The laying of signal shielding line needs to be determined in combination with the later line connection, system requirements and noise conditions.
对于系统要求较高的工程或者现场电磁干扰较强的情况,在线缆铺设时可以考虑单独为音响系统埋设自己的信号真正的地线,埋设要求基本与电源地线要求基本一样,只是要与电源地线区分开,而且埋设的必要性和可行性都要认真分析。
For projects with high system requirements or strong on-site electromagnetic interference, when laying the cable, you can consider embedding your own signal real ground wire for the sound system alone. The embedding requirements are basically the same as those of the power ground wire, but they should be separated from the power ground wire, and the necessity and feasibility of embedding should be carefully analyzed.
需要提醒大家的是:线缆的铺设虽然看似简单,进行起来时也比较快,但是如果只图快,盲目蛮干,反倒容易导致施工工作受阻或者给工程留下隐患。更多注意事项您可以来网站

It is necessary to remind you that although the laying of cables seems simple and fast, if you only try to be fast and blindly act recklessly, it is easy to hinder the construction work or leave hidden dangers to the project. You can come to the website for more precautions consulting service
