Hello everyone, I am a hydropower engineer from Guangdong, China.
I have 19 years of hydropower work experience. I have to share my work with you today.

---

Our company has purchased a number of electric boxes today. These electrical boxes are the systems I have planned.
In the original design drawings. When I reviewed the drawings, I had a lot of unnecessary steps, and it was very troublesome to construct.
So after obtaining the consent of the design institute. I have recalculated the system diagram. And redo a detailed information.
Because my calculations are reasonable, I also save unnecessary trouble. Soon the design institute approved the documents.

---

I also customized this batch of electric boxes in the first place, and spent half a month before and after. I finally gotten through this matter.
Customized electrical boxes and electrical cabinets are also here. The weather will be installed in these two days. Above is the appearance of the electric box.
A total of two streets. The total length is 2.9 kilometers. Divided into seven system electrical boxes. I roughly made the electrical box configuration into a form. Make it easier to understand.
Because the original manuscript is a bit fuzzy in Figure: 6.
大家好，我是来自中国广东的一名水电工程师。
我有19年的水电工作经验。今天有要和大家分享我的工作情况。

我们公司今天已经购买到了一批电箱。这些电箱是由我规划的系统。
在原设计的图纸中。我审核图纸的时候出现了很多不必要的步骤，而且施工起来也十分麻烦。
所以征得设计院的同意后。我对系统图重新做了计算。并重做了一分详细资料。
因为我的计算比较合理，也省去了不必要的麻烦。很快设计院就批了文件。

---

我也在第一时间定制了这批电箱，前前后后花费了半个月的时间。总算折腾了完了这件事。
定制的电箱和电柜也到了。这两天天气好就会进行安装。上面是电箱的样貌。
总共两条街。全长2.9公里。分为七个系统电箱。我大致的将电箱配置制作成一张表格。让人更加容易看得懂。
因为原本的手稿在图：6中有点模糊。

This is the specific configuration of this electrical box. If you are not a professional person, there may be some places that you don't understand. As a construction industry. This should be a general system diagram. The main purpose of this form is to make reference for people in the same industry.
If you have a similar job, be cautious when reviewing drawings. The system diagram is not a floor plan. The planning imagination of the system diagram is much longer than the reality. There are many factors to consider. My system diagram evolved through calculation. Mainly used, Figure: 4. This street lighting. If there is a need to install the power box, it will be calculated separately.

If you have something you don't understand, you can add my micro signal: aellly. I will explain the calculation method of the power box dl and al lighting for you. You can also pay attention to the "Watermelon Home Circuit Course". I will explain them one by one in future articles. The principle and rational application of the planing power. I remember the one sentence I said before: The electrician is a special job and can't play. To understand it, to harness it, to apply it to the fullest.

Knowing it can benefit more people.

这就是这个电箱的具体配置。如果不是专业的人看，可能有些地方看不懂。当作为建筑行业中。这应该是普遍的系统图，我做出这个表格主要目的是让同一种行业的人做参考。
如果你有类似的工作，在审核图纸的时候一定要谨慎，系统图不是平面图。系统图的规划想象要比现实长远很多，考虑的因素非常的多，我这份系统图通过计算演变而来的。主要用于，图：4。这种街道照明。如果有需要安装动力箱就要另行计算。

如果你有不明白的地方可以添加我的微信号：aellly。我一定为你讲解动力电箱dl和al照明的计算方式。你也可以留意《西瓜居家电路课》。在以后的文章中会一一讲解。解刨电的原理和合理运用。我记得我以前说过的一句话：电工是特殊工作，不能儿戏。要懂它、驾驭它、要把它运用到淋漓尽致。

懂它才能造福更多的人。
