大連(lian)變壓器柜(ju)是(shi)本(ben)公司產(chan)品的其(qi)中一種，

而大(da)連變頻控制箱 它的(de)空氣(qi)開(kai)關 一(yi)個(ge)總(zong)的(de)空氣(qi)開(kai)關，這個(ge)是整個(ge)柜體的(de)電源控制。相(xiang)信(xin)每個(ge)柜子都(dou)必(bi)須(xu)要有的(de)一(yi)個(ge)東西(xi)。 

大連PLC控制柜 這(zhe)個(ge)要根據工程(cheng)需要選(xuan)擇。打個(ge)比(bi)方如(ru)(ru)果工程(cheng)小(xiao)可以直接就是(shi)一(yi)個(ge)一(yi)體(ti)化(hua)的PLC但(dan)如(ru)(ru)果工程(cheng)比(bi)較(jiao)大可能就需要模塊、卡件(jian)式的，同時還可能需要冗余（也就是(shi)兩套交(jiao)替(ti)使用）。 

電(dian)(dian)源(yuan) ，一個24VDC的開關(guan)電(dian)(dian)源(yuan)，大多數的PLC都是自(zi)帶24VDC的電(dian)(dian)源(yuan)，根據是否確實需要來定是否要這個開關(guan)電(dian)(dian)源(yuan)。 

繼(ji)(ji)電器(qi)(qi)(qi) 一般PLC是(shi)可以直接將(jiang)指令(ling)發到(dao)控制(zhi)回路(lu)(lu)(lu)里，但(dan)也(ye)可能先由繼(ji)(ji)電器(qi)(qi)(qi)中轉。打個(ge)比方，如果你(ni)(ni)PLC的輸出口帶(dai)電是(shi)24VDC的，但(dan)是(shi)你(ni)(ni)的控制(zhi)回路(lu)(lu)(lu)里畫的圖需要PLC供的節(jie)(jie)點卻是(shi)220VAC的，那么你(ni)(ni)就必須在PLC輸出口加上一個(ge)繼(ji)(ji)電器(qi)(qi)(qi)，即指令(ling)發出時(shi)繼(ji)(ji)電器(qi)(qi)(qi)動作，但(dan)后讓控制(zhi)回路(lu)(lu)(lu)的節(jie)(jie)點接到(dao)繼(ji)(ji)電器(qi)(qi)(qi)的常(chang)開或常(chang)閉點上。也(ye)是(shi)根據情況選擇是(shi)否使用繼(ji)(ji)電器(qi)(qi)(qi)。 

1.空氣(qi)(qi)斷路(lu)器是(shi)一種不(bu)(bu)僅能正(zheng)常接(jie)觸(chu)和斷開電(dian)(dian)(dian)(dian)(dian)路(lu)，并能在過(guo)電(dian)(dian)(dian)(dian)(dian)流、逆電(dian)(dian)(dian)(dian)(dian)流、短(duan)路(lu)和失（欠）電(dian)(dian)(dian)(dian)(dian)壓(ya)等非正(zheng)常情況下動作(zuo)(zuo)的自(zi)動電(dian)(dian)(dian)(dian)(dian)器。其(qi)主要作(zuo)(zuo)用(yong)是(shi)保護交、直流電(dian)(dian)(dian)(dian)(dian)路(lu)內的電(dian)(dian)(dian)(dian)(dian)氣(qi)(qi)設備(bei)，也可以不(bu)(bu)頻(pin)繁地操作(zuo)(zuo)電(dian)(dian)(dian)(dian)(dian)路(lu)。在這里用(yong)來迅速切斷變頻(pin)器，防止變頻(pin)器及(ji)其(qi)線路(lu)故障(zhang)導致電(dian)(dian)(dian)(dian)(dian)源故障(zhang)。  

2.交流電(dian)抗器又叫AC電(dian)抗器、電(dian)源協調(diao)用的交流電(dian)抗器。其主要功(gong)能(neng)是防(fang)止(zhi)電(dian)源電(dian)網的諧波干擾。 

3.交(jiao)流接觸(chu)器簡稱接觸(chu)器。它是用來(lai)頻繁遠距離接通和分斷交(jiao)直流電(dian)路，或大(da)電(dian)容控(kong)制電(dian)路的(de)自動(dong)電(dian)器。這里主(zhu)要(yao)用于變頻器出(chu)現故障(zhang)時，自動(dong)切斷主(zhu)電(dian)源(yuan)并防止掉電(dian)及故障(zhang)后再起動(dong)。 ;

大連電氣控制柜的控(kong)制(zhi)(zhi)器(qi)形(xing)狀和尺寸取(qu)(qu)決于電(dian)氣(qi)控(kong)制(zhi)(zhi)柜(ju)的控(kong)制(zhi)(zhi)器(qi)上手或腳使用部位尺寸和電(dian)氣(qi)控(kong)制(zhi)(zhi)柜(ju)的控(kong)制(zhi)(zhi)器(qi)操(cao)作時用力(li)(li)方(fang)式。手用工具的設計要使手或腳的用力(li)(li)部位與電(dian)氣(qi)控(kong)制(zhi)(zhi)柜(ju)的控(kong)制(zhi)(zhi)器(qi)重量分(fen)配相互匹配，同(tong)時采取(qu)(qu)一(yi)定的防(fang)誤操(cao)作措施，如(ru)電(dian)氣(qi)控(kong)制(zhi)(zhi)柜(ju)的控(kong)制(zhi)(zhi)器(qi)表(biao)面防(fang)滑(hua)、增加腳踏(ta)板行(xing)程等。
