按消(xiao)防(fang)(fang)規范要求，聯動控制(zhi)柜(ju)(ju)控制(zhi)電(dian)(dian)壓(ya)宜(yi)為(wei)DC24V，這不(bu)(bu)僅會(hui)加(jia)很(hen)(hen)多(duo)(duo)中(zhong)間繼電(dian)(dian)器(大(da)約(yue)2/3)，加(jia)很(hen)(hen)多(duo)(duo)觸點和(he)接線(xian)，而且(qie)線(xian)路長，電(dian)(dian)壓(ya)損(sun)失大(da)，加(jia)不(bu)(bu)可(ke)靠因素(su)，此(ci)舉看似安全(quan)，但失去了可(ke)靠性，有(you)些得不(bu)(bu)償失。實際上以前很(hen)(hen)多(duo)(duo)控制(zhi)柜(ju)(ju)包括現在很(hen)(hen)多(duo)(duo)工廠(chang)的控制(zhi)柜(ju)(ju)電(dian)(dian)源都采用(yong)AC220V，從未聽說(shuo)操作(zuo)(zuo)(zuo)人員(yuan)出現安全(quan)問題(ti)，至于(yu)檢修(xiu)人員(yuan)，當然要很(hen)(hen)熟悉電(dian)(dian)路，且(qie)要停(ting)電(dian)(dian)操作(zuo)(zuo)(zuo)，因此(ci)，強(qiang)電(dian)(dian)設備沒必要采用(yong)弱(ruo)電(dian)(dian)操作(zuo)(zuo)(zuo)。因此(ci)，建(jian)議消(xiao)防(fang)(fang)主管部門考(kao)慮修(xiu)改(gai)此(ci)項(xiang)規定。德惠風機
