描述：
作為(wei)直流(liu)隔離和交流(liu)耦合(he)裝(zhuang)置，SSD用于防止(zhi)陰極保護(hu)電(dian)(dian)(dian)(dian)(dian)流(liu)達到預(yu)定的閾(yu)值電(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)(ya)，同(tong)時(shi)還能傳導感應的交流(liu)電(dian)(dian)(dian)(dian)(dian)。當電(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)(ya)力圖超過(guo)(guo)閾(yu)值電(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)(ya)時(shi)，SSD立(li)即(ji)切(qie)換到短(duan)路模(mo)式，以(yi)提供過(guo)(guo)壓(ya)(ya)(ya)保護(hu).當過(guo)(guo)電(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)(ya)過(guo)(guo)去之后(hou)，又(you)自(zi)動切(qie)換回到直流(liu)隔離模(mo)式。這(zhe)樣的運行方(fang)式可以(yi)進行無數次,這(zhe)通常是由于交流(liu)故障(zhang)電(dian)(dian)(dian)(dian)(dian)流(liu)或(huo)雷(lei)電(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)流(liu)引起(qi)。SSD的標準(zhun)閡(he)值電(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)(ya)為(wei)-2V/+2V。閾(yu)值電(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)(ya)可以(yi)是值電(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)(ya)，或(huo)峰(feng)值電(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)(ya)，在此電(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)(ya)處(chu)切(qie)換發生，此電(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)(ya)為(wei)跨(kua)于隔離器兩(liang)
推薦產品：
作為直流隔(ge)離和交流耦合裝置(zhi)，SSD用于防止陰(yin)極保(bao)(bao)護電(dian)流達(da)到預定的(de)(de)閾值(zhi)(zhi)電(dian)壓(ya)(ya)(ya)，同時還(huan)能傳導感應的(de)(de)交流電(dian)。當電(dian)壓(ya)(ya)(ya)力(li)圖超過閾值(zhi)(zhi)電(dian)壓(ya)(ya)(ya)時，SSD立即切(qie)(qie)換到短路模式，以提供過壓(ya)(ya)(ya)保(bao)(bao)護.當過電(dian)壓(ya)(ya)(ya)過去之后，又自動(dong)切(qie)(qie)換回到直流隔(ge)離模式。這(zhe)樣的(de)(de)運(yun)行(xing)方式可以進行(xing)無數次,這(zhe)通常是(shi)由于交流故障電(dian)流或雷電(dian)電(dian)流引起。SSD的(de)(de)標準閡值(zhi)(zhi)電(dian)壓(ya)(ya)(ya)為-2V/+2V。閾值(zhi)(zhi)電(dian)壓(ya)(ya)(ya)可以是(shi)值(zhi)(zhi)電(dian)壓(ya)(ya)(ya)，或峰值(zhi)(zhi)電(dian)壓(ya)(ya)(ya)，在此電(dian)壓(ya)(ya)(ya)處切(qie)(qie)換發生，此電(dian)壓(ya)(ya)(ya)為跨于隔(ge)離器(qi)兩(liang)端(duan)的(de)(de)市流和交流峰值(zhi)(zhi)電(dian)壓(ya)(ya)(ya)之和。這(zhe)使得跨于SSD端(duan)子上的(de)(de)箝位電(dian)壓(ya)(ya)(ya)很低、很。
