聚碳酸酯表箱中會(hui)使用以溫(wen)(wen)度(du)為標準(zhun)的(de)操縱(zong)電(dian)(dian)路，一般(ban)會(hui)相互配合電(dian)(dian)阻加(jia)熱(re)(re)器(qi)來(lai)實現全部電(dian)(dian)路操縱(zong)。以溫(wen)(wen)度(du)控制為標準(zhun)的(de)電(dian)(dian)路主電(dian)(dian)路中的(de)大功(gong)率(lv)電(dian)(dian)器(qi)運行狀態由(you)溫(wen)(wen)度(du)決策。所(suo)顯(xian)示電(dian)(dian)路便是有溫(wen)(wen)度(du)操縱(zong)的(de)電(dian)(dian)阻加(jia)熱(re)(re)器(qi)電(dian)(dian)路。

從(cong)圖所顯(xian)示的(de)電(dian)(dian)(dian)路可以看得出，聚碳(tan)酸酯(zhi)表(biao)箱(xiang)主電(dian)(dian)(dian)路中的(de)器(qi)(qi)材是電(dian)(dian)(dian)阻加熱器(qi)(qi)(rt)。電(dian)(dian)(dian)阻加熱器(qi)(qi)由(you) tr 低(di)壓(ya)變壓(ya)器(qi)(qi)和橋式整流(liu)(liu)電(dian)(dian)(dian)路配電(dian)(dian)(dian)。低(di)壓(ya)變壓(ya)器(qi)(qi)的(de)開(kai)關電(dian)(dian)(dian)源為單相電(dian)(dian)(dian)220v 交流(liu)(liu)電(dian)(dian)(dian)流(liu)(liu)。
