　　1.了解用戶所需,根據(jù)實(shí)際情況選擇**適合用戶的柜型。　　2.盡量采用國內(nèi)**廠家的國產(chǎn)柜型,不能盲目選擇技術(shù)參數(shù)比較高的進(jìn)口配電柜,這樣易造成資源浪費(fèi)。　　3.由于進(jìn)口配電柜中所采用的主要元器件的品牌與柜體是一致的。所以選擇進(jìn)口配電柜時(shí),應(yīng)注意主要元器件的參數(shù),它必須能滿足用戶需要。注意事項(xiàng) （1）施工用電配電系統(tǒng)應(yīng)設(shè)置總配電箱、分配電箱、開關(guān)箱，并按照“總-分-開”順序作分級(jí)設(shè)置，并形成“三級(jí)配電”模式。（2）施工用配電系統(tǒng)各配電箱、開關(guān)箱的安裝位置要合理?？偱潆娤湟M量靠近變壓器或外電源處，以便電源的引入。分配電箱應(yīng)盡量安裝在用電設(shè)備或負(fù)荷相對(duì)集中的中心地帶，確保三相負(fù)荷保持平衡。開關(guān)箱安裝的位置應(yīng)視現(xiàn)場(chǎng)情況和工況盡量靠近其控制的用電設(shè)備。

2、拼裝結(jié)構(gòu)：把鈑金件分開加工，每個(gè)部件加工好以后在組裝，用螺絲和三通加固鎖死，外觀漂亮，操作簡(jiǎn)單，可以節(jié)約大量的運(yùn)輸成本。配電箱和配電柜、配電盤、配電屏、電器柜等，是集中安裝開關(guān)、儀表等設(shè)備的成套裝置。原理配電箱是按電氣接線要求將開關(guān)設(shè)備、測(cè)量?jī)x表、保護(hù)電器和輔助設(shè)備組裝在封閉或半封閉金屬柜中或屏幅上，構(gòu)成低壓配電箱。正常運(yùn)行時(shí)可借助手動(dòng)或自動(dòng)開關(guān)接通或分?jǐn)嚯娐?。故障或不正常運(yùn)行時(shí)借助保護(hù)電器切斷電路或報(bào)警。借測(cè)量?jī)x表可顯示運(yùn)行中的各種參數(shù)，還可對(duì)某些電氣參數(shù)進(jìn)行調(diào)整，對(duì)偏離正常工作狀態(tài)進(jìn)行提示或發(fā)出信號(hào)。
