按消防規范(fan)要求，聯動(dong)控(kong)制柜控(kong)制電壓宜為DC24V，這不(bu)僅(jin)會加(jia)很(hen)多(duo)(duo)中(zhong)間(jian)繼電器(qi)(大約2/3)，加(jia)很(hen)多(duo)(duo)觸(chu)點和接線，而且(qie)線路(lu)長，電壓損失大，加(jia)不(bu)可靠因(yin)(yin)素，此(ci)(ci)舉(ju)看似安(an)全(quan)，但失去了可靠性，有些得(de)不(bu)償失。實際上以前很(hen)多(duo)(duo)控(kong)制柜包括現(xian)(xian)在很(hen)多(duo)(duo)工廠的控(kong)制柜電源都采用(yong)AC220V，從未聽說(shuo)操(cao)作(zuo)人員出(chu)現(xian)(xian)安(an)全(quan)問題，至于(yu)檢(jian)修人員，當然要很(hen)熟悉電路(lu)，且(qie)要停電操(cao)作(zuo)，因(yin)(yin)此(ci)(ci)，強電設備沒必要采用(yong)弱電操(cao)作(zuo)。因(yin)(yin)此(ci)(ci)，建議消防主管部門考慮修改此(ci)(ci)項規定。德惠風(feng)機
