消防應急集中電源原理是什么  ——浙江新黎明環保有限公司


浙江新黎明(ming)環保有限公司小(xiao)知(zhi)識(shi):


  “通(tong)過電(dian)(dian)(dian)路給里面的蓄電(dian)(dian)(dian)池充電(dian)(dian)(dian),由(you)于電(dian)(dian)(dian)路里面有(you)欠(qian)壓繼電(dian)(dian)(dian)器一類的欠(qian)壓電(dian)(dian)(dian)磁機構,這(zhe)個繼電(dian)(dian)(dian)器只有(you)在外部電(dian)(dian)(dian)壓突然(ran)(ran)降低到設定值以(yi)下或者是完全沒(mei)有(you)電(dian)(dian)(dian)壓時才會動(dong)作,所以(yi)平時電(dian)(dian)(dian)網正(zheng)常(chang)(chang)時它(ta)不動(dong)作,燈(deng)不亮。只有(you)突然(ran)(ran)斷電(dian)(dian)(dian)時,它(ta)才動(dong)作,轉到由(you)蓄電(dian)(dian)(dian)池供電(dian)(dian)(dian),此時燈(deng)亮。當(dang)電(dian)(dian)(dian)網再次(ci)恢復正(zheng)常(chang)(chang)時,又(you)自動(dong)切換至充電(dian)(dian)(dian)狀態,燈(deng)熄滅。”
