style="text-indent:25px"> 對于配電變壓器容量在100kV?A及以上的配電箱體，在箱內(nèi)散熱窗靠側(cè)壁處，應考慮到安裝溫控繼電器（JU-3型或JU-4超小型溫度繼電器）和軸流風機，安裝在控制電器板上方左側(cè)面的箱體上，以便使箱內(nèi)溫度達到一定值時（如40℃）能自動啟動排氣扇，強行排出熱量以使箱體散熱。采用保護電路防止配電箱供電的外部電路故障的發(fā)生。選擇體積較小的智能缺相保護器，如可選用DA88CM-II型電機缺相保護模塊(上海產(chǎn)品)安裝于配電箱內(nèi)以防止因低壓缺相運行而燒壞電動機。改進原配電箱的低壓電容器組的接線方式，將其安裝位置由交流接觸器上樁頭，改成接在配電箱低壓進線與計量表計之間。防止因運行中電容器電路發(fā)生缺相故障或電容器損壞時，造成計量裝置計量不準確。此外，電容器選擇型號應為BSMJ系列產(chǎn)品，以保證元件質(zhì)量可靠、安全運行。

　　1.了解用戶所需,根據(jù)實際情況選擇**適合用戶的柜型。　　2.盡量采用國內(nèi)**廠家的國產(chǎn)柜型,不能盲目選擇技術參數(shù)比較高的進口配電柜,這樣易造成資源浪費。　　3.由于進口配電柜中所采用的主要元器件的品牌與柜體是一致的。所以選擇進口配電柜時,應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（1）施工用電配電系統(tǒng)應設置總配電箱、分配電箱、開關箱，并按照“總-分-開”順序作分級設置，并形成“三級配電”模式。（2）施工用配電系統(tǒng)各配電箱、開關箱的安裝位置要合理。總配電箱要盡量靠近變壓器或外電源處，以便電源的引入。分配電箱應盡量安裝在用電設備或負荷相對集中的中心地帶，確保三相負荷保持平衡。開關箱安裝的位置應視現(xiàn)場情況和工況盡量靠近其控制的用電設備。東光配電箱哪家好</p><p
