請教各位師傅：
我最近在做停電應急預案，遇到一個(gè)問(wèn)題：在市電停電后，是否有必要斷開(kāi)所有支路末端的負載開(kāi)關(guān)？比如風(fēng)機的斷路器，當然，斷路器后端還有交流接觸器的。
詳細一點(diǎn)的情況是：配電房的開(kāi)關(guān)會(huì )斷開(kāi)，配電房出來(lái)后就到了各負載配電箱，配電箱里有很多斷路器，各斷路器下面各自有交流接觸器，當市電停電后，我在配電房把開(kāi)關(guān)斷了后，各支路末端負載開(kāi)關(guān)需不需要斷呢？

單個(gè)設備一個(gè)總接觸器 失壓保護就有了

你也贊成不用再斷末端斷路器嗎？
