選用(yong)節能型交(jiao)(jiao)流(liu)接觸(chu)器(qi)（類似CJ20SI型）產(chan)品(pin)，并注(zhu)意交(jiao)(jiao)流(liu)接觸(chu)器(qi)線(xian)圈電(dian)(dian)(dian)壓與所選剩(sheng)作電(dian)(dian)(dian)流(liu)動作保護器(qi)的相對應接線(xian)端子相連(lian)，注(zhu)意進(jin)行正確的負載匹配。選擇交(jiao)(jiao)流(liu)接觸(chu)器(qi)時，應選用(yong)其(qi)絕緣等級(ji)為A級(ji)及(ji)以上產(chan)品(pin)，必須保證其(qi)主回路(lu)觸(chu)點的額(e)(e)定電(dian)(dian)(dian)流(liu)應大于或(huo)等于被(bei)控制的線(xian)路(lu)的負荷電(dian)(dian)(dian)流(liu)。接觸(chu)器(qi)的電(dian)(dian)(dian)磁線(xian)圈額(e)(e)定電(dian)(dian)(dian)壓為380V或(huo)220 V

暗裝配(pei)(pei)(pei)電(dian)(dian)箱，配(pei)(pei)(pei)電(dian)(dian)箱嵌(qian)入(ru)墻(qiang)(qiang)內安(an)裝，在砌墻(qiang)(qiang)時(shi)預(yu)(yu)留孔洞(dong)應比配(pei)(pei)(pei)電(dian)(dian)箱的(de)(de)長和寬各(ge)大20mm左(zuo)右，預(yu)(yu)留的(de)(de)深度(du)(du)為配(pei)(pei)(pei)電(dian)(dian)箱厚度(du)(du)加上洞(dong)內壁抹灰的(de)(de)厚度(du)(du)。在圬埋(mai)配(pei)(pei)(pei)電(dian)(dian)箱時(shi)，箱體(ti)與墻(qiang)(qiang)之間填以混凝土即可(ke)把箱體(ti)固定住(zhu)。

由于電(dian)(dian)動(dong)汽車(che)每(mei)天需要補充(chong)大(da)量電(dian)(dian)能(neng)(neng)，經(jing)(jing)營充(chong)電(dian)(dian)站(zhan)(zhan)就可以獲得巨(ju)大(da)的充(chong)電(dian)(dian)服(fu)務(wu)(wu)收(shou)益。相對于加油(you)站(zhan)(zhan)，電(dian)(dian)能(neng)(neng)比較安全和方便(bian)，可在(zai)各地(di)大(da)量安裝(zhuang)設置充(chong)電(dian)(dian)站(zhan)(zhan)。根據(ju)投資規(gui)模，小到(dao)社區慢(man)速充(chong)電(dian)(dian)樁，大(da)到(dao)公路快速充(chong)電(dian)(dian)站(zhan)(zhan)，單(dan)站(zhan)(zhan)經(jing)(jing)營，組網(wang)(wang)經(jing)(jing)營均可。對于充(chong)電(dian)(dian)站(zhan)(zhan)市(shi)場(chang)的開放，國家(jia)電(dian)(dian)網(wang)(wang)以后可能(neng)(neng)更(geng)多地(di)會偏向服(fu)務(wu)(wu)和電(dian)(dian)力供應，讓充(chong)電(dian)(dian)站(zhan)(zhan)建設更(geng)充(chong)分地(di)與市(shi)場(chang)融合，大(da)家(jia)都將(jiang)是(shi)同(tong)一個市(shi)場(chang)的競爭者(zhe)。因(yin)此提(ti)前準備(bei)、提(ti)前規(gui)劃，對從事(shi)電(dian)(dian)池生產的企業(ye)來說很(hen)重要。充(chong)換電(dian)(dian)市(shi)場(chang)，政(zheng)策有傾(qing)斜，市(shi)場(chang)有潛(qian)力，投資又少，將(jiang)面臨較大(da)的商機。
