本發明涉及(ji)(ji)電氣工程(cheng)技術(shu)領域，具體涉及(ji)(ji)一種(zhong)四角煤(mei)粉鍋爐供電系統。

背景技術：

在火力發電(dian)(dian)廠中四角煤(mei)粉(fen)鍋(guo)爐(lu)占所有類型的(de)(de)(de)鍋(guo)爐(lu)的(de)(de)(de)70%以上，目前常(chang)規的(de)(de)(de)四角煤(mei)粉(fen)鍋(guo)爐(lu)的(de)(de)(de)供電(dian)(dian)和(he)(he)接(jie)線方法是將(jiang)電(dian)(dian)源柜和(he)(he)控制(zhi)柜布置(zhi)在主(zhu)廠房或集控樓的(de)(de)(de)配電(dian)(dian)間和(he)(he)電(dian)(dian)子設(she)備(bei)間，從配電(dian)(dian)間和(he)(he)電(dian)(dian)子設(she)備(bei)間分別通過(guo)電(dian)(dian)源和(he)(he)控制(zhi)電(dian)(dian)纜送到鍋(guo)爐(lu)的(de)(de)(de)四角，采用(yong)這種常(chang)規的(de)(de)(de)方式(shi)主(zhu)要存在以下缺陷。

1.需(xu)要規劃從配(pei)電(dian)(dian)間(jian)(jian)和電(dian)(dian)子設備(bei)間(jian)(jian)至(zhi)鍋爐四個燃燒角的(de)多層電(dian)(dian)纜通道(dao)，由于電(dian)(dian)纜橋架需(xu)要穿(chuan)過煤倉間(jian)(jian)、鍋爐鋼(gang)架等，因此設計較(jiao)為復雜，且(qie)難度較(jiao)大(da)。

2.從配電間和電子設備(bei)間至鍋(guo)爐距離較(jiao)遠、電纜數量(liang)(liang)大(da)、橋(qiao)架(jia)層(ceng)數多，且鍋(guo)爐的每(mei)個執行結構均(jun)需多根電纜，因此需要耗(hao)費大(da)量(liang)(liang)的電纜和橋(qiao)架(jia)，施工工程(cheng)量(liang)(liang)較(jiao)大(da)。

3.電(dian)源(yuan)開關布置在配(pei)電(dian)間(jian)的(de)電(dian)源(yuan)柜內，現場檢(jian)修和調試分合(he)電(dian)源(yuan)需要(yao)與(yu)配(pei)電(dian)間(jian)人員聯系配(pei)合(he)進(jin)行操(cao)作，并且(qie)容易(yi)造(zao)成安全隱(yin)患(huan)。

4.電(dian)源柜和接線(xian)柜占(zhan)用(yong)主廠房和配電(dian)間的寶貴(gui)空(kong)間，增(zeng)加了(le)建筑(zhu)投資(zi)。

鑒于此，特提出此發明(ming)。
