配电能的箱体就叫配电柜,主要用作对用电设备的控制、配电,对线路的过载、短路、漏电起保护作用。配电柜内包括接线端子、保护设备、各种刀闸、计量设备以及测量设备等,应用较为广泛。
The distribution box is called a distribution cabinet, mainly used for controlling and distributing electrical equipment, and for protecting the circuit from overload, short circuit, and leakage. The distribution cabinet includes wiring terminals, protective equipment, various switches, measuring equipment, and measuring equipment, which are widely used.
主要用作对电力线路、主要用电设备的控制、监视、测量与保护。常设置在变电站、配电室等场合。那么配电柜的进线出线方式有哪些?需要相关注意哪些事项呢?下面济南电缆桥架厂小编浅浅地给大家介绍一下。
Mainly used for control, monitoring, measurement, and protection of power lines and major electrical equipment. It is often installed in substations, distribution rooms, and other occasions. So what are the incoming and outgoing methods of the distribution cabinet? What precautions should be taken? Next, we will introduce the cable tray factory to you.
配电柜的进线出线方式:
The incoming and outgoing methods of the distribution cabinet:
配电柜的进出线方式形式多种,有上进下出,还有下进上出,也有侧进上出,侧进下出等;
There are various ways of incoming and outgoing lines in the distribution cabinet, including top in and bottom out, bottom in and top out, side in and top out, side in and bottom out, etc;
1、具体形式的选择根据进线柜如果与上段柜并柜,那就是侧进;
1. The specific form selection depends on whether the incoming cabinet is combined with the upper section cabinet, which is side entry;
2、如果上段柜非并柜,那就走电缆或者母线桥;电缆可以上进也可以下进,母线桥就需要上进了;
2. If the upper cabinet is not a combined cabinet, then use a cable or bus bridge; The cable can be fed up or down, so the bus bridge needs to be fed up;
3、出线方式根据工程要求来选择,如果有电缆沟就下出,如果是电缆桥架就上出;(具情况而定)
3. The outgoing mode shall be selected according to the project requirements. If there is a cable trench, the outgoing mode shall be downward, and if there is a cable tray, the outgoing mode shall be upward; (depending on the situation)
(1)进线方式:电流流进配电柜的入口处在哪儿就决定了进线方式,比如从柜顶流进来的(这种方式一般通过母线槽引电流来),就叫上进;从柜底流进来的叫下进(这种方式一般用电缆引电流来);从柜侧流进来的就叫侧进(这种方式一般用在进线柜和变压器紧挨着的时候等等)。
(1) Incoming method: The location of the entrance where the current flows into the distribution cabinet determines the incoming method. For example, if the current flows in from the top of the cabinet (usually through the bus duct), it is called incoming; What flows in from the bottom of the cabinet is called downflow (this method usually uses cables to draw current); The flow in from the cabinet side is called side entry (this method is generally used when the incoming cabinet and transformer are adjacent, etc.).
(2)出线方式:电流流出配电柜的出口在哪儿就决定了出线方式,如上,但一般只有上出线,和下出线二种方式。
(2) Outlet method: The outlet where the current flows out of the distribution cabinet determines the outlet method. As mentioned above, there are generally only two methods: upper outlet and lower outlet.

配电柜进出线相关注意事项:
Precautions for incoming and outgoing lines of distribution cabinets:
在计算配电柜到配电柜,电缆长度时,如何考虑配电柜在哪里进线和出线的?
When calculating the cable length from the distribution cabinet to the distribution cabinet, how do you consider where the distribution cabinet enters and exits?
一般根据经验,一般来说你,如果未设置电缆沟,一般配电盘柜大部分从顶出线,这特别表现在配电室内,如果是配电箱一般是从箱底出线。
Based on experience, generally speaking, if there is no cable trench set up, most of the distribution panels and cabinets come out from the top, which is particularly evident in the distribution room. If it is a distribution box, it usually comes out from the bottom of the box.
在计算配电柜到配电柜电缆长度时应该是按加长2米考虑的配电柜一般是在配电柜底部进线和出线的。
When calculating the cable length from the distribution cabinet to the distribution cabinet, it should be considered to extend it by 2 meters. The distribution cabinet is usually equipped with incoming and outgoing lines at the bottom of the distribution cabinet.
TN-C-S系统通常以进线配电箱作为TN-C和S的分界点,就是进线4根,出线5根,N和PE在配电箱前合一称为PEN线,配电箱后分开而且不再接触。N线不再接地,PE线只可以接用电设备的金属外壳,不能接中性线,可以多处接地,还做总等电位连结。
The TN-C-S system usually uses the incoming distribution box as the dividing point between TN-C and S, with 4 incoming lines and 5 outgoing lines. N and PE merge in front of the distribution box and are called PEN lines, which are separated and no longer in contact after the distribution box. The N wire is no longer grounded, and the PE wire can only be connected to the metal shell of the electrical equipment, not to the neutral wire. It can be grounded in multiple places and also connected to a total equipotential connection.
TN-C-S系统当然可以进四出五了,PEN入户接地分成N,PE。强调一点就是以后这两根线不可以再合并了,从这个配电箱以后就只能是TN-S系统了。
The TN-C-S system can of course enter four out five, and PEN is divided into N and PE for household grounding. One point to emphasize is that these two lines cannot be merged in the future, and from this distribution box onwards, it can only be the TN-S system.
