大連變(bian)壓器柜是本公司產品(pin)的其中一種,
而大連變頻控(kong)制箱 它的(de)空氣開關 一個(ge)(ge)總(zong)的(de)空氣開關,這個(ge)(ge)是(shi)整個(ge)(ge)柜體(ti)的(de)電源(yuan)控(kong)制。相信每個(ge)(ge)柜子都必須要(yao)有的(de)一個(ge)(ge)東西。
大連PLC控制柜 這個(ge)要(yao)根據工(gong)程(cheng)需要(yao)選(xuan)擇。打(da)個(ge)比方如(ru)果(guo)工(gong)程(cheng)小可(ke)以直接就(jiu)是(shi)一個(ge)一體化的PLC但如(ru)果(guo)工(gong)程(cheng)比較大可(ke)能就(jiu)需要(yao)模(mo)塊、卡件式的,同(tong)時還可(ke)能需要(yao)冗(rong)余(也就(jiu)是(shi)兩套交替使用)。
電源(yuan) ,一個24VDC的(de)開(kai)關電源(yuan),大多(duo)數的(de)PLC都(dou)是(shi)自帶(dai)24VDC的(de)電源(yuan),根據是(shi)否(fou)確實需要來定是(shi)否(fou)要這(zhe)個開(kai)關電源(yuan)。
繼電(dian)器(qi)(qi) 一般PLC是(shi)(shi)(shi)可以直接將指令發(fa)到控(kong)(kong)制(zhi)回路里,但(dan)也可能(neng)先(xian)由(you)繼電(dian)器(qi)(qi)中轉(zhuan)。打個比方,如(ru)果你PLC的(de)(de)(de)輸(shu)出(chu)口帶電(dian)是(shi)(shi)(shi)24VDC的(de)(de)(de),但(dan)是(shi)(shi)(shi)你的(de)(de)(de)控(kong)(kong)制(zhi)回路里畫的(de)(de)(de)圖需(xu)要(yao)PLC供的(de)(de)(de)節點(dian)卻是(shi)(shi)(shi)220VAC的(de)(de)(de),那么(me)你就必須在PLC輸(shu)出(chu)口加上一個繼電(dian)器(qi)(qi),即指令發(fa)出(chu)時(shi)繼電(dian)器(qi)(qi)動(dong)作,但(dan)后讓控(kong)(kong)制(zhi)回路的(de)(de)(de)節點(dian)接到繼電(dian)器(qi)(qi)的(de)(de)(de)常(chang)開或常(chang)閉(bi)點(dian)上。也是(shi)(shi)(shi)根據(ju)情況選擇是(shi)(shi)(shi)否使(shi)用繼電(dian)器(qi)(qi)。
1.空氣斷路器(qi)是一種不僅能(neng)(neng)正常(chang)(chang)接觸和(he)斷開(kai)電(dian)(dian)路,并能(neng)(neng)在過電(dian)(dian)流(liu)、逆電(dian)(dian)流(liu)、短路和(he)失(shi)(欠)電(dian)(dian)壓等非正常(chang)(chang)情(qing)況下動作的自動電(dian)(dian)器(qi)。其主(zhu)要作用是保護交、直(zhi)流(liu)電(dian)(dian)路內的電(dian)(dian)氣設(she)備(bei),也(ye)可以不頻繁地(di)操作電(dian)(dian)路。在這里用來迅(xun)速切斷變頻器(qi),防止(zhi)變頻器(qi)及其線路故障(zhang)導致(zhi)電(dian)(dian)源故障(zhang)。
2.交(jiao)流電抗(kang)(kang)器(qi)又叫AC電抗(kang)(kang)器(qi)、電源協調用的交(jiao)流電抗(kang)(kang)器(qi)。其(qi)主要功(gong)能是防止電源電網的諧波干擾。
3.交流接(jie)(jie)(jie)觸器(qi)簡稱接(jie)(jie)(jie)觸器(qi)。它是用(yong)來頻繁遠距離接(jie)(jie)(jie)通和分斷(duan)交直流電(dian)(dian)路(lu),或大電(dian)(dian)容控制(zhi)電(dian)(dian)路(lu)的自動電(dian)(dian)器(qi)。這里主要用(yong)于變頻器(qi)出現故障時,自動切斷(duan)主電(dian)(dian)源(yuan)并防(fang)止掉電(dian)(dian)及故障后(hou)再起動。
大連電氣控制柜的(de)(de)控(kong)(kong)(kong)制(zhi)(zhi)(zhi)(zhi)(zhi)器(qi)形(xing)狀(zhuang)和尺寸取決(jue)于電(dian)(dian)氣(qi)控(kong)(kong)(kong)制(zhi)(zhi)(zhi)(zhi)(zhi)柜(ju)的(de)(de)控(kong)(kong)(kong)制(zhi)(zhi)(zhi)(zhi)(zhi)器(qi)上手(shou)(shou)或腳(jiao)(jiao)使(shi)用(yong)部位(wei)(wei)尺寸和電(dian)(dian)氣(qi)控(kong)(kong)(kong)制(zhi)(zhi)(zhi)(zhi)(zhi)柜(ju)的(de)(de)控(kong)(kong)(kong)制(zhi)(zhi)(zhi)(zhi)(zhi)器(qi)操作時用(yong)力方式。手(shou)(shou)用(yong)工具(ju)的(de)(de)設(she)計要使(shi)手(shou)(shou)或腳(jiao)(jiao)的(de)(de)用(yong)力部位(wei)(wei)與電(dian)(dian)氣(qi)控(kong)(kong)(kong)制(zhi)(zhi)(zhi)(zhi)(zhi)柜(ju)的(de)(de)控(kong)(kong)(kong)制(zhi)(zhi)(zhi)(zhi)(zhi)器(qi)重量分配(pei)相互匹(pi)配(pei),同時采(cai)取一(yi)定的(de)(de)防誤操作措(cuo)施,如(ru)電(dian)(dian)氣(qi)控(kong)(kong)(kong)制(zhi)(zhi)(zhi)(zhi)(zhi)柜(ju)的(de)(de)控(kong)(kong)(kong)制(zhi)(zhi)(zhi)(zhi)(zhi)器(qi)表面防滑、增加腳(jiao)(jiao)踏板行程等。
