產(chǎn)品名稱：嵌入式配電箱產(chǎn)品介紹：嵌入式配電箱是應(yīng)用于辦公嵌入式、居民小區(qū)、廠房等共用場所，嵌入式配電箱主要由交流斷路器、指示燈、電壓電流表等部分組成，由市電供電，工作穩(wěn)定、可靠、有短路保護、過流保護、過電壓保護等作用。一般為三相無線制供電為主，支路由饋線空開保護提供電源。產(chǎn)品特性：價格低廉、用處、適用于各種惡劣環(huán)境。有電流、電壓、功率等監(jiān)測功能。電源特性：工作電壓可在±10%范圍內(nèi)運行，工作頻率為50HZ。工作環(huán)境指標(biāo)：u工作溫度：-5℃～55℃u貯存溫度：-20℃～+55℃u工作相對濕度：不大于80％（+30℃時））u貯存相對濕度：≤90％～96％（40℃±2℃）u大氣壓力：65～110kpa產(chǎn)品尺寸：可根據(jù)客戶需求定制。 </p><p> 畫完電路圖，接下來就是確定主要元器件的規(guī)格型號。確定主要部件的規(guī)格和型號。熱繼電器:根據(jù)電機電流，選擇熱繼電器的額定電流。由于熱繼電器在該電路中既有過載保護又有斷相保護，所以在選擇時要注意選擇帶斷相保護的熱繼電器。通過查看熱繼電器選型表，可以看出“NR2-25”型熱繼電器的額定電流為9-13A。交流接觸器:根據(jù)電機功率和啟動條件，交流接觸器的額定電流可以是18A。此外，由于控制電路需要一組交流接觸器的常開觸點，所以接觸器型號可選擇為“CJ22-1810”。保險絲:根據(jù)熔斷器的選擇規(guī)則，用熔斷器保護電機時，溶液的額定電流應(yīng)等于電機電流的。如果按2倍計算，主線保險絲FU1的額定電流應(yīng)為2x11=22A。根據(jù)熔斷器選擇表，主線熔斷器FU1的額定電流可以是25A?？刂凭€保險絲FU2的額定電流可以是2A。電線:根據(jù)導(dǎo)線安全電流表或電流估算公式，導(dǎo)線選用；如果線槽內(nèi)導(dǎo)線較多或溫度較高，可選用。斷路器(空開):只要斷路器是用來保護導(dǎo)線不被燒壞的，根據(jù)斷路器的選擇規(guī)則，斷路器的額定電流應(yīng)小于線路的安全載流量。

在密封上，普通配電箱對密封要求不很嚴格，防爆配電箱蓋子與箱體密封較好，并經(jīng)過嚴格檢驗合格后，由專門機構(gòu)簽發(fā)合格證明，并予以出廠銷售。在應(yīng)用上，普通配電箱一般應(yīng)用于民用和沒有防爆要求的場所。防爆配電箱主要用于危險性可燃氣體場所及性場所。在價格上，普通配電箱價格便宜。防爆配電箱昂貴，一般是普通配電箱價格數(shù)倍。配電箱一般是家庭用的，而配電柜則多用在集中供電中，比如說工業(yè)配電用電和建筑用電等，配電箱和配電柜都屬于成套設(shè)備，配電箱屬于低壓成套設(shè)備，配電柜有高壓有低壓家用配電箱規(guī)格1、當(dāng)電箱只是照明電箱或者小動力時。
