一般情況下級斷路器（如變壓器低壓側(cè)進(jìn)線）宜選用過載長...斷路器作為上下級保護(hù)時，其動作應(yīng)有選擇性，上下級間應(yīng)相互配合，并注意如下問題：1）斷路器的上下級動作為選擇性時，應(yīng)注意電流脫扣器整定值與時間配?。 2、在線圈兩端并聯(lián)壓敏電阻壓敏電阻的特性是在它兩端的電壓低于某一數(shù)值時，它幾乎不導(dǎo)電，相當(dāng)于開路；而當(dāng)其上電壓超過某一數(shù)值以后，它被擊穿，幾乎相當(dāng)于短路。只要我們選擇壓敏電阻的工作電流大于線圈的電流，壓敏電阻在斷電以后又可以恢復(fù)開路狀態(tài)。

電壓互感器本身是一個阻抗很小的電壓源，正常運(yùn)行時負(fù)載阻抗很大，相當(dāng)于開路狀態(tài)，二次側(cè)僅有很小的負(fù)載電流。如果二次側(cè)短路，負(fù)載阻抗為零或很小，二次側(cè)通過的電流增大，將會造成二次側(cè)熔斷器熔斷，儀表指示不正常、繼電保護(hù)裝置誤動作。
