按(an)消(xiao)防(fang)(fang)規范(fan)要(yao)(yao)求，聯動控制柜(ju)控制電(dian)(dian)(dian)(dian)壓宜為DC24V，這(zhe)不僅會加(jia)很多中(zhong)間繼(ji)電(dian)(dian)(dian)(dian)器(大約2/3)，加(jia)很多觸點和接線(xian)，而且線(xian)路(lu)長，電(dian)(dian)(dian)(dian)壓損失大，加(jia)不可靠(kao)因素，此舉看(kan)似安(an)全(quan)，但失去了可靠(kao)性，有些得不償失。實際上以(yi)前(qian)很多控制柜(ju)包括(kuo)現在很多工廠的控制柜(ju)電(dian)(dian)(dian)(dian)源都采用(yong)AC220V，從未聽說操(cao)作(zuo)(zuo)人員出現安(an)全(quan)問題，至于(yu)檢(jian)修人員，當(dang)然(ran)要(yao)(yao)很熟悉電(dian)(dian)(dian)(dian)路(lu)，且要(yao)(yao)停(ting)電(dian)(dian)(dian)(dian)操(cao)作(zuo)(zuo)，因此，強電(dian)(dian)(dian)(dian)設備沒必要(yao)(yao)采用(yong)弱電(dian)(dian)(dian)(dian)操(cao)作(zuo)(zuo)。因此，建議(yi)消(xiao)防(fang)(fang)主管部門考慮修改此項規定。德(de)惠風(feng)機
