大連變壓(ya)器柜是本(ben)公司產品(pin)的其中一種(zhong)，

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

大連PLC控制柜 這個要(yao)根據(ju)工程需要(yao)選擇(ze)。打個比方如(ru)果(guo)工程小(xiao)可以直接就是一(yi)個一(yi)體化的PLC但(dan)如(ru)果(guo)工程比較大可能(neng)就需要(yao)模塊、卡件式的，同時(shi)還可能(neng)需要(yao)冗余(yu)（也就是兩套交替使用）。 

電(dian)源(yuan) ，一個24VDC的開(kai)關電(dian)源(yuan)，大(da)多數的PLC都是自帶24VDC的電(dian)源(yuan)，根(gen)據是否確實需要(yao)來定是否要(yao)這(zhe)個開(kai)關電(dian)源(yuan)。 

繼(ji)(ji)(ji)電(dian)(dian)(dian)器(qi) 一般PLC是(shi)可以直接將(jiang)指(zhi)令發到(dao)控(kong)制(zhi)回路(lu)里，但也可能先由繼(ji)(ji)(ji)電(dian)(dian)(dian)器(qi)中轉(zhuan)。打個比方，如(ru)果(guo)你PLC的(de)(de)(de)輸(shu)出口帶電(dian)(dian)(dian)是(shi)24VDC的(de)(de)(de)，但是(shi)你的(de)(de)(de)控(kong)制(zhi)回路(lu)里畫的(de)(de)(de)圖需要PLC供的(de)(de)(de)節(jie)點(dian)卻(que)是(shi)220VAC的(de)(de)(de)，那么你就必須在PLC輸(shu)出口加上(shang)一個繼(ji)(ji)(ji)電(dian)(dian)(dian)器(qi)，即指(zhi)令發出時繼(ji)(ji)(ji)電(dian)(dian)(dian)器(qi)動作，但后(hou)讓(rang)控(kong)制(zhi)回路(lu)的(de)(de)(de)節(jie)點(dian)接到(dao)繼(ji)(ji)(ji)電(dian)(dian)(dian)器(qi)的(de)(de)(de)常開(kai)或常閉點(dian)上(shang)。也是(shi)根據情況選擇(ze)是(shi)否使(shi)用(yong)繼(ji)(ji)(ji)電(dian)(dian)(dian)器(qi)。 

1.空氣(qi)斷(duan)路器(qi)是一種不僅能正(zheng)常接觸和斷(duan)開電(dian)(dian)(dian)(dian)路，并(bing)能在過電(dian)(dian)(dian)(dian)流、逆電(dian)(dian)(dian)(dian)流、短(duan)路和失（欠）電(dian)(dian)(dian)(dian)壓等非(fei)正(zheng)常情況下(xia)動(dong)作的自動(dong)電(dian)(dian)(dian)(dian)器(qi)。其(qi)主要作用(yong)是保護交(jiao)、直(zhi)流電(dian)(dian)(dian)(dian)路內的電(dian)(dian)(dian)(dian)氣(qi)設備，也可以不頻(pin)繁地(di)操作電(dian)(dian)(dian)(dian)路。在這里(li)用(yong)來(lai)迅(xun)速切斷(duan)變(bian)頻(pin)器(qi)，防(fang)止變(bian)頻(pin)器(qi)及其(qi)線路故(gu)障導致電(dian)(dian)(dian)(dian)源故(gu)障。  

2.交流電(dian)(dian)(dian)抗(kang)器又叫AC電(dian)(dian)(dian)抗(kang)器、電(dian)(dian)(dian)源協調用(yong)的(de)交流電(dian)(dian)(dian)抗(kang)器。其主要(yao)功能(neng)是防(fang)止電(dian)(dian)(dian)源電(dian)(dian)(dian)網的(de)諧(xie)波干(gan)擾。 

3.交流(liu)接觸器(qi)(qi)簡稱(cheng)接觸器(qi)(qi)。它是用來頻繁(fan)遠距離接通(tong)和分斷交直流(liu)電(dian)(dian)(dian)路(lu)，或大電(dian)(dian)(dian)容(rong)控制電(dian)(dian)(dian)路(lu)的(de)自(zi)動(dong)電(dian)(dian)(dian)器(qi)(qi)。這里主要用于(yu)變頻器(qi)(qi)出現故障時，自(zi)動(dong)切斷主電(dian)(dian)(dian)源(yuan)并防止掉電(dian)(dian)(dian)及故障后再起動(dong)。 

大連電氣控制柜的(de)控(kong)(kong)(kong)(kong)(kong)制(zhi)(zhi)(zhi)(zhi)器(qi)形狀和尺寸取(qu)決于電(dian)(dian)氣(qi)(qi)(qi)控(kong)(kong)(kong)(kong)(kong)制(zhi)(zhi)(zhi)(zhi)柜(ju)的(de)控(kong)(kong)(kong)(kong)(kong)制(zhi)(zhi)(zhi)(zhi)器(qi)上手或(huo)(huo)腳(jiao)使用(yong)部(bu)位(wei)尺寸和電(dian)(dian)氣(qi)(qi)(qi)控(kong)(kong)(kong)(kong)(kong)制(zhi)(zhi)(zhi)(zhi)柜(ju)的(de)控(kong)(kong)(kong)(kong)(kong)制(zhi)(zhi)(zhi)(zhi)器(qi)操(cao)作(zuo)時用(yong)力(li)方(fang)式。手用(yong)工具的(de)設計要使手或(huo)(huo)腳(jiao)的(de)用(yong)力(li)部(bu)位(wei)與電(dian)(dian)氣(qi)(qi)(qi)控(kong)(kong)(kong)(kong)(kong)制(zhi)(zhi)(zhi)(zhi)柜(ju)的(de)控(kong)(kong)(kong)(kong)(kong)制(zhi)(zhi)(zhi)(zhi)器(qi)重量分配相互匹配，同(tong)時采取(qu)一定的(de)防誤操(cao)作(zuo)措施(shi)，如電(dian)(dian)氣(qi)(qi)(qi)控(kong)(kong)(kong)(kong)(kong)制(zhi)(zhi)(zhi)(zhi)柜(ju)的(de)控(kong)(kong)(kong)(kong)(kong)制(zhi)(zhi)(zhi)(zhi)器(qi)表面(mian)防滑、增(zeng)加腳(jiao)踏板行程等(deng)。
