● 工作原理

當常(chang)(chang)(chang)(chang)用(yong)(yong)電(dian)(dian)源(yuan)(yuan)(yuan)正(zheng)常(chang)(chang)(chang)(chang)，功能鍵置于自動擋時，備(bei)(bei)(bei)用(yong)(yong)斷(duan)路(lu)器分、常(chang)(chang)(chang)(chang)用(yong)(yong)斷(duan)路(lu)器合，以(yi)保護常(chang)(chang)(chang)(chang)用(yong)(yong)電(dian)(dian)源(yuan)(yuan)(yuan)接通負載。當常(chang)(chang)(chang)(chang)用(yong)(yong)電(dian)(dian)源(yuan)(yuan)(yuan)一(yi)相或三相全(quan)部(bu)電(dian)(dian)壓中斷(duan)時，ATS 將(jiang)負載從(cong)常(chang)(chang)(chang)(chang)用(yong)(yong)電(dian)(dian)源(yuan)(yuan)(yuan)轉(zhuan)換到(dao)備(bei)(bei)(bei)用(yong)(yong)電(dian)(dian)源(yuan)(yuan)(yuan)（當備(bei)(bei)(bei)用(yong)(yong)電(dian)(dian)源(yuan)(yuan)(yuan)有(you)正(zheng)常(chang)(chang)(chang)(chang)電(dian)(dian)壓時），并在常(chang)(chang)(chang)(chang)用(yong)(yong)電(dian)(dian)源(yuan)(yuan)(yuan)恢復至(zhi)(zhi)正(zheng)常(chang)(chang)(chang)(chang)時，又將(jiang)備(bei)(bei)(bei)用(yong)(yong)電(dian)(dian)源(yuan)(yuan)(yuan)轉(zhuan)換至(zhi)(zhi)常(chang)(chang)(chang)(chang)用(yong)(yong)電(dian)(dian)源(yuan)(yuan)(yuan)。
