大連變壓器柜(ju)是(shi)本公司產品的其(qi)中一(yi)種，

而大連變頻控制箱 它的(de)(de)空氣(qi)開(kai)關 一個(ge)總的(de)(de)空氣(qi)開(kai)關，這個(ge)是整個(ge)柜體的(de)(de)電源控制。相信每(mei)個(ge)柜子都必須要有的(de)(de)一個(ge)東西。 

大連PLC控制柜 這個要(yao)根據工(gong)程(cheng)需(xu)要(yao)選擇(ze)。打個比方如(ru)果工(gong)程(cheng)小可(ke)(ke)以直接就是一個一體(ti)化的PLC但如(ru)果工(gong)程(cheng)比較大可(ke)(ke)能(neng)就需(xu)要(yao)模塊、卡件(jian)式的，同時(shi)還可(ke)(ke)能(neng)需(xu)要(yao)冗余(yu)（也(ye)就是兩套交替使用(yong)）。 

電源(yuan) ，一個(ge)24VDC的開關電源(yuan)，大(da)多數(shu)的PLC都是(shi)自帶(dai)24VDC的電源(yuan)，根據是(shi)否(fou)確實需要來(lai)定是(shi)否(fou)要這個(ge)開關電源(yuan)。 

繼電(dian)器(qi)(qi) 一般PLC是(shi)可以直接(jie)將(jiang)指令(ling)發到控(kong)制回路(lu)里(li)(li)，但(dan)也可能先由繼電(dian)器(qi)(qi)中轉。打個(ge)比(bi)方，如(ru)果你(ni)(ni)PLC的輸出(chu)(chu)口帶電(dian)是(shi)24VDC的，但(dan)是(shi)你(ni)(ni)的控(kong)制回路(lu)里(li)(li)畫的圖需要PLC供的節(jie)點(dian)卻是(shi)220VAC的，那(nei)么你(ni)(ni)就必須在PLC輸出(chu)(chu)口加上一個(ge)繼電(dian)器(qi)(qi)，即指令(ling)發出(chu)(chu)時繼電(dian)器(qi)(qi)動作，但(dan)后讓控(kong)制回路(lu)的節(jie)點(dian)接(jie)到繼電(dian)器(qi)(qi)的常開或(huo)常閉點(dian)上。也是(shi)根據情況選擇是(shi)否使用繼電(dian)器(qi)(qi)。 

1.空氣斷(duan)路(lu)器(qi)是一種不僅能正常接(jie)觸和(he)斷(duan)開電(dian)(dian)(dian)路(lu)，并能在(zai)過(guo)電(dian)(dian)(dian)流、逆電(dian)(dian)(dian)流、短路(lu)和(he)失(shi)（欠）電(dian)(dian)(dian)壓等(deng)非正常情況下動作的(de)自(zi)動電(dian)(dian)(dian)器(qi)。其(qi)主要作用是保護(hu)交、直(zhi)流電(dian)(dian)(dian)路(lu)內的(de)電(dian)(dian)(dian)氣設備，也(ye)可以不頻繁地操作電(dian)(dian)(dian)路(lu)。在(zai)這里用來迅速切斷(duan)變(bian)頻器(qi)，防止變(bian)頻器(qi)及其(qi)線(xian)路(lu)故障(zhang)導致電(dian)(dian)(dian)源故障(zhang)。  

2.交(jiao)流電(dian)抗(kang)器(qi)又叫AC電(dian)抗(kang)器(qi)、電(dian)源協(xie)調用的(de)交(jiao)流電(dian)抗(kang)器(qi)。其(qi)主要功(gong)能是防止電(dian)源電(dian)網的(de)諧波(bo)干擾。 

3.交流(liu)接觸器(qi)(qi)簡稱接觸器(qi)(qi)。它是用來頻(pin)繁遠距離接通(tong)和分斷交直流(liu)電(dian)(dian)路，或大(da)電(dian)(dian)容控制電(dian)(dian)路的(de)自動電(dian)(dian)器(qi)(qi)。這里主要(yao)用于變頻(pin)器(qi)(qi)出現故障(zhang)時，自動切斷主電(dian)(dian)源并防(fang)止(zhi)掉電(dian)(dian)及故障(zhang)后再起動。 

大連電氣控制柜的(de)(de)(de)控(kong)(kong)(kong)制(zhi)(zhi)(zhi)器(qi)(qi)形狀(zhuang)和尺寸(cun)取(qu)決于電氣控(kong)(kong)(kong)制(zhi)(zhi)(zhi)柜的(de)(de)(de)控(kong)(kong)(kong)制(zhi)(zhi)(zhi)器(qi)(qi)上(shang)手或(huo)腳(jiao)使用(yong)(yong)部(bu)位尺寸(cun)和電氣控(kong)(kong)(kong)制(zhi)(zhi)(zhi)柜的(de)(de)(de)控(kong)(kong)(kong)制(zhi)(zhi)(zhi)器(qi)(qi)操作(zuo)(zuo)時用(yong)(yong)力(li)方式。手用(yong)(yong)工(gong)具的(de)(de)(de)設(she)計要(yao)使手或(huo)腳(jiao)的(de)(de)(de)用(yong)(yong)力(li)部(bu)位與電氣控(kong)(kong)(kong)制(zhi)(zhi)(zhi)柜的(de)(de)(de)控(kong)(kong)(kong)制(zhi)(zhi)(zhi)器(qi)(qi)重量分配相(xiang)互匹配，同時采取(qu)一(yi)定的(de)(de)(de)防(fang)誤(wu)操作(zuo)(zuo)措施，如電氣控(kong)(kong)(kong)制(zhi)(zhi)(zhi)柜的(de)(de)(de)控(kong)(kong)(kong)制(zhi)(zhi)(zhi)器(qi)(qi)表面(mian)防(fang)滑、增加腳(jiao)踏板行程等。
