在廣州甚至廣東的住宅小區電氣設計中,一般都會涉及到小區的高低壓供配電系統的設計.如10kV高壓配電系統圖,低壓配電系統圖等等圖紙一大堆.然而在真正實施過程中,供電部門(尤其是供電公司指定的所謂電力設計小公司)根本將這些圖紙作為一回事,按其電腦里原有的電子檔圖紙將數據稍作改動以及斷路器按其所好換個廠家名稱便美其名曰設計(可笑不?),拿出來的圖紙根本無法滿足電氣設計的設計意圖,致使嚴重存在以下問題:(也不知道是職業道德問題還是根本一竅不通)
1.跟原設計的電氣系統貨不對板,存在與低壓開關柜后出線回路嚴重沖突,對實際施工造成嚴重阻礙,經常要求設計單位改動原有電氣系統圖才能滿足它的要求(壟斷的沒話說).
2.對消防負荷和非消防負荷的供電(主要在高層建筑里)應嚴格分回路(從母線段)都不清楚,將消防負荷和非消防負荷按一個回路出線(尤其是將電梯和消防電梯,地下室的動力合在一起等等,有的甚至將樓頂消防風機和梯間照明合在一個回路,以一個表計量).
3.系統接地保護接地型式由原設計的TN-S系統竟曲解成"TN-S-C-S"系統(室內的還需要做TN-C,好玩吧?),嚴格的按照所謂的"三相四線制"再做重復接地來實施,導致后續施工中存在重復浪費資源以及安全隱患等等問題..
............................(違反建筑電氣設計規范等等問題實在不好意思一一例舉,給那幫人留點混飯吃的面子算了)
總之吧,在通過圖紙審查后的電氣設計圖紙在這幫人的眼里根本不知何物,經常是完工后的高低壓供配電系統已是面目全非了,能有百分之五十的保留已經是謝天謝地了.
所以.我覺得:住宅建筑電氣設計,讓供電部門走!大不了留點位置,讓他供幾個必需回路的電,愛怎么折騰讓他自個怎么折騰去..
Guangzhou, Guangdong, even in the electrical design of residential quarters, generally involving high-low cell power supply system design. 10kV power distribution systems, such as maps, drawings, etc. low-voltage distribution system map a lot. But in the real implementation of the process, the power sector (especially the so-called power supply design company appointed a small company) did these drawings for one thing, according to computer drawings of the original electronic file data to make a little change, and circuit breakers by their the name of another manufacturer will be sounding good design (ridiculously?), drawing out the design simply can not meet the electrical design intent, resulting in a serious following problems: (do not know or not know nothing about ethical issues)

1. With the original design of the electrical system not meeting board, the existence and low voltage switchgear circuit after qualifying serious conflicts seriously hinder the actual construction, often require changes to the original design unit plans to meet its electrical system requirements (monopoly impress ).

2. On the fire load and fire load of non-supply (mainly in high-rise building in) should be strictly sub-loop (from the bus segment) are not clear, the fire load and fire load of non-qualifying press of a circuit (especially the elevator and fire elevator, basement, etc. together power, and some fans and even the roof of the staircase lighting the fire together in a loop to a table measurement).

3. Grounding system grounding protection type of the original design of the TN-S system actually twisted into a "TN-SCS" system (needs to be done indoors TN-C, fun, right?), Strictly in accordance with the so-called "three-phase four-wire system "do repeat the ground to implement, resulting in repeated follow-up construction of a waste of resources and the existence of security risks and so on ..

............................( Violation of building electrical design and so on enumerate really sorry to those people leave bread where the face Forget)

In short it, the review by drawing the electrical design drawings in the group of people's eyes do not know what, often after the completion of the high and low voltage power supply system has been distorted beyond recognition, and to have 50 percent of reservations have been is thankful.

So. I think: residential building electrical design for power sector to go! Big deal leave here, let him for a few essential circuits of power, love how frustrating tossing him from a how to ..

你好
其實這個好像沒有明文指出，或者是我不知道。
但是一般情況是建筑工程的”附屬“電氣設計是由建筑設計院完成的。例如，是某個小區、或是具體某個建筑的供配電設計，需要注意是“相關”專業兩個字，因此這種情況一般的電源入點不太可能大于10KV以上。
如果是某個區域供配電，不知道具體的用電對象，不是給某個具體的建筑或是住區供電，這種情況一般由電力設計院來設計。

根據該廠負荷統計資料及所能取得的電源和用電負荷的實際情況，并適當考慮到工廠將來的發展，進行設計，有一臺或兩臺變壓器，一般一臺比較經濟一點

你好！
我是做高壓柜試驗的
你說的這傳動，你看高壓柜，柜頂是不是有一排小母線，大概有15個端子左右
你看圖紙上面有操作電壓，操作電源找到后，就可以進行斷路器的操作了。
一般我們還要做電流一段 電流二段跳閘的試驗（這就要給柜子里的電流互感器通流）
說的有點兒亂，有不明白的地方你提出來，很樂意給你解答
