2. 當(dāng)兩個及以上斷路器串接時，其相互間可形成后備保護配合或選擇性保護配合(參見第7章)。
注意：
上表所列的值只適用于前頁所描述的條件下，表中所選斷路器只考慮到工作電流及預(yù)期短路電流，要想正確選型，還必須要考慮到線路的選擇保護，后備保護及是否
需要選擇限流型斷路器等等。因此，設(shè)計人員應(yīng)仔細進行驗證。
以上斷路器一般只針對Emax 系列。對于有(*)標(biāo)識斷路器，也可選用Tmax 或 Isomax S 系列斷路器。必須記住，上表所得出的數(shù)值是假設(shè)變壓器一次側(cè)的系統(tǒng)容量是
750MVA。同時，對于連接銅排的阻抗也沒有考慮進去。
