描述：
作為(wei)直流(liu)隔(ge)離和交(jiao)(jiao)流(liu)耦合裝(zhuang)置，SSD用于防止陰極保護(hu)(hu)電(dian)(dian)(dian)流(liu)達到(dao)(dao)(dao)預(yu)定的閾值電(dian)(dian)(dian)壓(ya)(ya)(ya)(ya)，同時還能傳導感(gan)應的交(jiao)(jiao)流(liu)電(dian)(dian)(dian)。當(dang)電(dian)(dian)(dian)壓(ya)(ya)(ya)(ya)力圖超過(guo)(guo)閾值電(dian)(dian)(dian)壓(ya)(ya)(ya)(ya)時，SSD立即切(qie)換(huan)(huan)到(dao)(dao)(dao)短路模式(shi)，以提供過(guo)(guo)壓(ya)(ya)(ya)(ya)保護(hu)(hu).當(dang)過(guo)(guo)電(dian)(dian)(dian)壓(ya)(ya)(ya)(ya)過(guo)(guo)去之后(hou)，又自動(dong)切(qie)換(huan)(huan)回到(dao)(dao)(dao)直流(liu)隔(ge)離模式(shi)。這樣的運行(xing)方式(shi)可以進行(xing)無數(shu)次,這通常是(shi)由于交(jiao)(jiao)流(liu)故障電(dian)(dian)(dian)流(liu)或雷電(dian)(dian)(dian)電(dian)(dian)(dian)流(liu)引起。SSD的標準閡值電(dian)(dian)(dian)壓(ya)(ya)(ya)(ya)為(wei)-2V/+2V。閾值電(dian)(dian)(dian)壓(ya)(ya)(ya)(ya)可以是(shi)值電(dian)(dian)(dian)壓(ya)(ya)(ya)(ya)，或峰值電(dian)(dian)(dian)壓(ya)(ya)(ya)(ya)，在此(ci)電(dian)(dian)(dian)壓(ya)(ya)(ya)(ya)處切(qie)換(huan)(huan)發生(sheng)，此(ci)電(dian)(dian)(dian)壓(ya)(ya)(ya)(ya)為(wei)跨于隔(ge)離器兩

作為直(zhi)流(liu)隔(ge)(ge)離(li)(li)和交(jiao)(jiao)流(liu)耦(ou)合裝(zhuang)置，SSD用(yong)于(yu)防止陰極保護(hu)(hu)電(dian)(dian)(dian)流(liu)達到(dao)預定的(de)(de)閾值(zhi)(zhi)電(dian)(dian)(dian)壓(ya)(ya)，同時還能(neng)傳導感應的(de)(de)交(jiao)(jiao)流(liu)電(dian)(dian)(dian)。當電(dian)(dian)(dian)壓(ya)(ya)力圖超過閾值(zhi)(zhi)電(dian)(dian)(dian)壓(ya)(ya)時，SSD立(li)即切換(huan)(huan)到(dao)短路(lu)模式，以(yi)提供過壓(ya)(ya)保護(hu)(hu).當過電(dian)(dian)(dian)壓(ya)(ya)過去之后，又自(zi)動(dong)切換(huan)(huan)回到(dao)直(zhi)流(liu)隔(ge)(ge)離(li)(li)模式。這(zhe)樣(yang)的(de)(de)運行方式可以(yi)進行無數次,這(zhe)通常(chang)是由于(yu)交(jiao)(jiao)流(liu)故(gu)障電(dian)(dian)(dian)流(liu)或雷電(dian)(dian)(dian)電(dian)(dian)(dian)流(liu)引(yin)起。SSD的(de)(de)標準閡值(zhi)(zhi)電(dian)(dian)(dian)壓(ya)(ya)為-2V/+2V。閾值(zhi)(zhi)電(dian)(dian)(dian)壓(ya)(ya)可以(yi)是值(zhi)(zhi)電(dian)(dian)(dian)壓(ya)(ya)，或峰值(zhi)(zhi)電(dian)(dian)(dian)壓(ya)(ya)，在此電(dian)(dian)(dian)壓(ya)(ya)處切換(huan)(huan)發生，此電(dian)(dian)(dian)壓(ya)(ya)為跨于(yu)隔(ge)(ge)離(li)(li)器兩端的(de)(de)市(shi)流(liu)和交(jiao)(jiao)流(liu)峰值(zhi)(zhi)電(dian)(dian)(dian)壓(ya)(ya)之和。這(zhe)使(shi)得跨于(yu)SSD端子上的(de)(de)箝(qian)位電(dian)(dian)(dian)壓(ya)(ya)很低、很。
