大連控制柜、變頻控制箱和大連PLC變頻控制柜出現在市場中引起銷(xiao)售熱潮，其功(gong)(gong)能(neng)全(quan)面特點是(shi)起到很大(da)作(zuo)用，不同(tong)功(gong)(gong)能(neng)迎合到市場不同(tong)用戶群體，迅速占據到各(ge)大(da)市場空間。以下就來為大(da)家(jia)全(quan)面介紹(shao)PLC變頻控制(zhi)柜功(gong)(gong)能(neng)信息內容： 

1、電源(yuan)切換與(yu)保(bao)(bao)護功能(neng)，PLC變頻(pin)控(kong)(kong)制柜(ju)通常設計有(you)短路(lu)器(qi)元件，連(lian)接著進線電源(yuan)，可以(yi)幫(bang)助變頻(pin)設備完成電路(lu)通斷控(kong)(kong)制，并能(neng)夠在(zai)電路(lu)和(he)變頻(pin)器(qi)出現(xian)短路(lu)或是運行過載時給予(yu)保(bao)(bao)護，解決設備在(zai)運行中(zhong)會發生電力輸送安全(quan)問(wen)題，對操控(kong)(kong)人員人身安全(quan)起(qi)到保(bao)(bao)護。 

2、變頻(pin)調速(su)功能，PLC變頻(pin)控制柜面板上設(she)(she)有變頻(pin)調速(su)用電(dian)位器，可(ke)以根據(ju)操作人員(yuan)輸(shu)(shu)送頻(pin)率，向電(dian)機輸(shu)(shu)送指令(ling)信號，控制電(dian)機運行速(su)度，并且(qie)在(zai)部分產品設(she)(she)有工頻(pin)切換功能，以確(que)保變頻(pin)器出現故障(zhang)(zhang)時，可(ke)以通過裝置實(shi)現最(zui)低(di)故障(zhang)(zhang)發生，減少設(she)(she)備出現損壞次數。 

國家發改委啟動的十大重(zhong)點節(jie)能(neng)(neng)(neng)工程之一(yi)就是電(dian)機(ji)(ji)系(xi)統(tong)(tong)節(jie)能(neng)(neng)(neng)，并要求：推廣變(bian)(bian)(bian)頻調速節(jie)能(neng)(neng)(neng)技(ji)(ji)術，風機(ji)(ji)、水(shui)泵、壓(ya)縮機(ji)(ji)等通用機(ji)(ji)械(xie)系(xi)統(tong)(tong)采用變(bian)(bian)(bian)頻調速節(jie)能(neng)(neng)(neng)措(cuo)施(shi)，工業(ye)機(ji)(ji)械(xie)采用交流電(dian)動機(ji)(ji)變(bian)(bian)(bian)頻調速技(ji)(ji)術；制定相(xiang)關經濟激勵政策、完善電(dian)機(ji)(ji)能(neng)(neng)(neng)效(xiao)標準體系(xi)等配套措(cuo)施(shi)；“十一(yi)五”期間，實(shi)現電(dian)機(ji)(ji)系(xi)統(tong)(tong)運行效(xiao)率提高2個百分(fen)點，形成年(nian)節(jie)電(dian)能(neng)(neng)(neng)力200億千瓦時。 

為推動全社(she)會(hui)展開(kai)節(jie)(jie)能(neng)降耗，緩解能(neng)源瓶頸的制約(yue)，建(jian)設節(jie)(jie)能(neng)型(xing)社(she)會(hui)，國家(jia)發(fa)(fa)改(gai)委制定(ding)了(le)《節(jie)(jie)能(neng)中(zhong)長期(qi)專項規劃(hua)》，并在(zai)2004年(nian)11月25日向全社(she)會(hui)發(fa)(fa)布。該“規劃(hua)”明(ming)確指出：能(neng)源是(shi)戰略資源，是(shi)全面建(jian)設小康社(she)會(hui)的重要(yao)物質(zhi)基(ji)礎(chu)，必須堅持節(jie)(jie)約(yue)優先。
