在廣州甚至廣東的住宅小區(qū)電氣設(shè)計(jì)中,一般都會(huì)涉及到小區(qū)的高低壓供配電系統(tǒng)的設(shè)計(jì).如10kV高壓配電系統(tǒng)圖,低壓配電系統(tǒng)圖等等圖紙一大堆.然而在真正實(shí)施過程中,供電部門(尤其是供電公司指定的所謂電力設(shè)計(jì)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(shù)據(jù)稍作改動(dòng)以及斷路器按其所好換個(gè)廠家名稱便美其名曰設(shè)計(jì)(可笑不?),拿出來的圖紙根本無法滿足電氣設(shè)計(jì)的設(shè)計(jì)意圖,致使嚴(yán)重存在以下問題:(也不知道是職業(yè)道德問題還是根本一竅不通)
1.跟原設(shè)計(jì)的電氣系統(tǒng)貨不對(duì)板,存在與低壓開關(guān)柜后出線回路嚴(yán)重沖突,對(duì)實(shí)際施工造成嚴(yán)重阻礙,經(jīng)常要求設(shè)計(jì)單位改動(dòng)原有電氣系統(tǒng)圖才能滿足它的要求(壟斷的沒話說).
2.對(duì)消防負(fù)荷和非消防負(fù)荷的供電(主要在高層建筑里)應(yīng)嚴(yán)格分回路(從母線段)都不清楚,將消防負(fù)荷和非消防負(fù)荷按一個(gè)回路出線(尤其是將電梯和消防電梯,地下室的動(dòng)力合在一起等等,有的甚至將樓頂消防風(fēng)機(jī)和梯間照明合在一個(gè)回路,以一個(gè)表計(jì)量).
3.系統(tǒng)接地保護(hù)接地型式由原設(shè)計(jì)的TN-S系統(tǒng)竟曲解成"TN-S-C-S"系統(tǒng)(室內(nèi)的還需要做TN-C,好玩吧?),嚴(yán)格的按照所謂的"三相四線制"再做重復(fù)接地來實(shí)施,導(dǎo)致后續(xù)施工中存在重復(fù)浪費(fèi)資源以及安全隱患等等問題..
............................(違反建筑電氣設(shè)計(jì)規(guī)范等等問題實(shí)在不好意思一一例舉,給那幫人留點(diǎn)混飯吃的面子算了)
總之吧,在通過圖紙審查后的電氣設(shè)計(jì)圖紙?jiān)谶@幫人的眼里根本不知何物,經(jīng)常是完工后的高低壓供配電系統(tǒng)已是面目全非了,能有百分之五十的保留已經(jīng)是謝天謝地了.
所以.我覺得:住宅建筑電氣設(shè)計(jì),讓供電部門走!大不了留點(diǎn)位置,讓他供幾個(gè)必需回路的電,愛怎么折騰讓他自個(gè)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(shí)這個(gè)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(shè)計(jì)是由建筑設(shè)計(jì)院完成的。例如，是某個(gè)小區(qū)、或是具體某個(gè)建筑的供配電設(shè)計(jì)，需要注意是“相關(guān)”專業(yè)兩個(gè)字，因此這種情況一般的電源入點(diǎn)不太可能大于10KV以上。
如果是某個(gè)區(qū)域供配電，不知道具體的用電對(duì)象，不是給某個(gè)具體的建筑或是住區(qū)供電，這種情況一般由電力設(shè)計(jì)院來設(shè)計(jì)。

根據(jù)該廠負(fù)荷統(tǒng)計(jì)資料及所能取得的電源和用電負(fù)荷的實(shí)際情況，并適當(dāng)考慮到工廠將來的發(fā)展，進(jìn)行設(shè)計(jì)，有一臺(tái)或兩臺(tái)變壓器，一般一臺(tái)比較經(jīng)濟(jì)一點(diǎn)

你好！
我是做高壓柜試驗(yàn)的
你說的這傳動(dòng)，你看高壓柜，柜頂是不是有一排小母線，大概有15個(gè)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(jìn)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(yàn)（這就要給柜子里的電流互感器通流）
說的有點(diǎn)兒亂，有不明白的地方你提出來，很樂意給你解答
