在農網改(gai)造(zao)(zao)中當時由于需求(qiu)的(de)(de)配電箱(xiang)數量大(da)、施工期(qi)短(duan)，配電箱(xiang)廠需要(yao)有關(guan)低壓電器的(de)(de)供貨(huo)時間急且(qie)數量多，因而產(chan)生了對(dui)產(chan)品質量的(de)(de)要(yao)求(qiu)不(bu)嚴格(ge)的(de)(de)現象，造(zao)(zao)成了一(yi)些產(chan)品投入運(yun)行(xing)(xing)后(hou)不(bu)久就(jiu)發生故障。如(ru)有些型(xing)號交流接觸(chu)器在配電箱(xiang)投運(yun)后(hou)不(bu)久，就(jiu)因接觸(chu)器合閘線圈燒(shao)壞，而無法運(yun)行(xing)(xing)。

對于配(pei)電(dian)變壓(ya)器容量在100kV·A及以(yi)上的配(pei)電(dian)箱體，在箱內散熱窗靠(kao)側壁處，應考慮到安裝溫(wen)控(kong)繼(ji)電(dian)器（JU-3型或JU-4超小(xiao)型溫(wen)度繼(ji)電(dian)器）和軸流風機，安裝在控(kong)制電(dian)器板上方左側面的箱體上，以(yi)便使(shi)箱內溫(wen)度達到一定值時（如40℃）能自動(dong)啟動(dong)排(pai)氣扇，強(qiang)行(xing)排(pai)出熱量以(yi)使(shi)箱體散熱。

暗裝配電箱，配電箱嵌入墻內安裝，直流充電樁在砌墻時預留孔洞應比配電箱的長和寬各大20mm左右，直流充電樁價格預留的深度為(wei)配(pei)電(dian)箱(xiang)厚度加上洞內壁抹灰(hui)的厚度。在圬埋配(pei)電(dian)箱(xiang)時(shi)，箱(xiang)體與墻(qiang)之(zhi)間填以(yi)混凝土即可(ke)把(ba)箱(xiang)體固定住。
