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(qi)銷售熱潮，其功(gong)能(neng)全面(mian)特(te)點是起(qi)到很大作用，不(bu)同(tong)功(gong)能(neng)迎合到市場不(bu)同(tong)用戶群體，迅速占據到各大市場空間。以下就來為大家全面(mian)介紹(shao)PLC變頻(pin)控制柜(ju)功(gong)能(neng)信息內容： 

1、電(dian)源(yuan)切(qie)換與保護(hu)功能，PLC變頻(pin)控制柜通常設(she)計有短(duan)(duan)路(lu)器元件，連接著進線電(dian)源(yuan)，可以幫助變頻(pin)設(she)備完成(cheng)電(dian)路(lu)通斷(duan)控制，并能夠在(zai)電(dian)路(lu)和變頻(pin)器出現短(duan)(duan)路(lu)或是運行過載時(shi)給予保護(hu)，解決設(she)備在(zai)運行中(zhong)會發生電(dian)力輸送安全問題，對(dui)操控人員人身(shen)安全起到保護(hu)。 

2、變頻(pin)調速(su)功(gong)能，PLC變頻(pin)控(kong)制柜面板上設(she)有(you)(you)變頻(pin)調速(su)用電位器(qi)，可以根據(ju)操(cao)作人員輸送頻(pin)率，向(xiang)電機輸送指令信號，控(kong)制電機運行速(su)度，并且在部(bu)分(fen)產品設(she)有(you)(you)工(gong)頻(pin)切(qie)換(huan)功(gong)能，以確保變頻(pin)器(qi)出現(xian)故障時，可以通過(guo)裝置實現(xian)最低故障發生，減少設(she)備(bei)出現(xian)損(sun)壞(huai)次數(shu)。 

國(guo)家發改委啟(qi)動的(de)十大重點節(jie)能(neng)工程之一就是電(dian)(dian)機(ji)系統節(jie)能(neng)，并(bing)要求：推廣變(bian)頻調(diao)(diao)速(su)節(jie)能(neng)技術(shu)，風機(ji)、水泵、壓縮機(ji)等(deng)通用(yong)機(ji)械系統采用(yong)變(bian)頻調(diao)(diao)速(su)節(jie)能(neng)措施，工業機(ji)械采用(yong)交(jiao)流電(dian)(dian)動機(ji)變(bian)頻調(diao)(diao)速(su)技術(shu)；制定相關經(jing)濟激勵(li)政(zheng)策(ce)、完善電(dian)(dian)機(ji)能(neng)效(xiao)標準體系等(deng)配套措施；“十一五”期間(jian)，實現電(dian)(dian)機(ji)系統運行效(xiao)率提高2個百分(fen)點，形成年節(jie)電(dian)(dian)能(neng)力200億千(qian)瓦時。 

為推(tui)動全社會展開(kai)節能降耗(hao)，緩解(jie)能源瓶頸的制約(yue)(yue)，建設節能型社會，國家(jia)發改委制定(ding)了《節能中(zhong)長期專項(xiang)規劃》，并在(zai)2004年11月25日(ri)向全社會發布。該“規劃”明(ming)確指出：能源是(shi)戰略資源，是(shi)全面(mian)建設小康社會的重要(yao)物質(zhi)基礎，必(bi)須堅持節約(yue)(yue)優先。
