有關金屬表箱以及接線難題的剖析(Analyse)

臨電系(xi)(xi)統軟件應采用“ 三(san)級操(cao)縱（control)， 兩方面維護” 系(xi)(xi)統軟件， 即采用總(zong)金(jin)屬(shu)表箱、分金(jin)屬(shu)表箱、開關(guan)箱三(san)級操(cao)縱， 等(deng)級分類配電設(she)備(bei) 另外在總(zong)金(jin)屬(shu)表箱和開關(guan)箱中(zhong)各自(zi)安設(she)漏電斷(duan)路器(qi)(qi)推行維護在通常情況下用電量(liang)機器(qi)(qi)設(she)備(bei)只有從開關(guan)箱中(zhong)接線(xian)(xian)而在實際上中(zhong)， 一些施工企業由于(yu)某(mou)一用電量(liang)機器(qi)(qi)設(she)備(bei)與分金(jin)屬(shu)表箱較為(wei)近就立即叢(cong)分金(jin)屬(shu)表箱中(zhong)接線(xian)(xian)應用，這不是安全性的。
