在系統(tǒng)的低壓電氣控制中，對于爐定設(shè)備還是采用傳統(tǒng)的控制方式，即配電室配電及控制，現(xiàn)場操作。而對于熱風(fēng)爐、布袋除塵、框槽配料采用配電室配電，現(xiàn)場控制及操作。在這種方法下，原來的控制室一般設(shè)兩個(gè)柜子：系統(tǒng)電源柜和現(xiàn)場分項(xiàng)配電柜。而原來放在控制室的電磁控制系統(tǒng)根據(jù)功能組進(jìn)行區(qū)分放在現(xiàn)場，實(shí)現(xiàn)現(xiàn)場電磁控制。
1：現(xiàn)場控制柜的設(shè)計(jì)
2：現(xiàn)場控制柜的安裝
2．1工程中電氣柜的安裝地點(diǎn)設(shè)計(jì)：
2．1．1布袋系統(tǒng)：該系統(tǒng)的控制柜包含10臺布袋箱體控制柜、1臺總管閥門控制柜、1臺出灰控制柜。

現(xiàn)場控制柜采用雙層密封門結(jié)構(gòu)，設(shè)計(jì)成操作區(qū)、電磁控制區(qū)、PLC控制區(qū)。其中操作區(qū)設(shè)計(jì)在柜門上，并采用防塵原件或是進(jìn)行防塵防水處理�？刂茀^(qū)設(shè)計(jì)在柜內(nèi)，其又分割成兩個(gè)區(qū)：電磁控制區(qū)和PLC控制區(qū)。兩個(gè)區(qū)完全隔離，以保證PLC系統(tǒng)的電磁兼容要求以及電氣安全要求。同時(shí)為了維護(hù)、維修、檢修方便，柜內(nèi)設(shè)低壓照明燈和檢修插座。
操作區(qū)：用于設(shè)計(jì)控制柜安放出的設(shè)備的手動(dòng)操作元件（其他的設(shè)備控制仍然采用就地箱就近控制）
電磁控制區(qū)：完成子系統(tǒng)中電磁設(shè)備的一次配電和二次電磁控制。
PLC控制區(qū)：完成PLC系統(tǒng)模塊及供電、輸入輸出隔離。為減少電磁干擾，PLC供電點(diǎn)采用直流方式，同時(shí)進(jìn)行隔離變壓器進(jìn)行電磁隔離；對于輸入輸出采用繼電器隔離，對于模擬量根據(jù)需要進(jìn)行隔離（因?yàn)楝F(xiàn)場一次元件直接進(jìn)入現(xiàn)場控制柜，干擾小，因此可以酌情處離）。
現(xiàn)場控制柜的安裝應(yīng)該考慮現(xiàn)場的空間要求因?yàn)楝F(xiàn)場空間以及設(shè)備的分布。在設(shè)計(jì)中首先考慮到現(xiàn)場設(shè)備的維修方便，而后才是電氣自身的要求。電氣控制首先在空間上應(yīng)該讓位于機(jī)械操作的便捷，圍繞著機(jī)械操作便捷展開。因此在空間上應(yīng)該選擇寬敞的地方。如果空間合適而不是和電氣的安全防護(hù)要求，則在電氣柜或其他方面采取措施。在空間的基礎(chǔ)上再考慮盡量接近設(shè)備最集中的地方。
（1）布袋箱體控制柜：設(shè)計(jì)安裝在布袋系統(tǒng)的第二層平臺。也就是中間灰斗平臺。同時(shí)布袋箱體卸灰系統(tǒng)設(shè)備的就地操作設(shè)計(jì)在柜體上。而布袋箱體的其他設(shè)備（支氣管到閥門、方散閥門）單獨(dú)設(shè)計(jì)現(xiàn)場就地箱控制并引入布袋箱體控制柜。
