大連控制柜、變頻控制箱和大連PLC變頻控制柜出現在市(shi)(shi)場(chang)中引起銷售熱(re)潮，其功(gong)(gong)能全面(mian)特點是起到(dao)(dao)很大作用，不(bu)同(tong)功(gong)(gong)能迎合到(dao)(dao)市(shi)(shi)場(chang)不(bu)同(tong)用戶群體，迅速(su)占據到(dao)(dao)各大市(shi)(shi)場(chang)空間(jian)。以下(xia)就(jiu)來(lai)為大家(jia)全面(mian)介紹PLC變頻控制柜功(gong)(gong)能信息(xi)內容： 

1、電源切(qie)換與保(bao)護功能，PLC變頻(pin)控(kong)制柜通(tong)常設(she)計有短路器元件(jian)，連接(jie)著進線(xian)電源，可以幫助變頻(pin)設(she)備完成電路通(tong)斷(duan)控(kong)制，并能夠在電路和變頻(pin)器出現短路或(huo)是運行過載(zai)時給予保(bao)護，解決設(she)備在運行中會發生電力輸送安(an)全問(wen)題，對操(cao)控(kong)人員(yuan)人身安(an)全起到保(bao)護。 

2、變(bian)頻(pin)調速功能，PLC變(bian)頻(pin)控(kong)制(zhi)柜面板上設(she)有(you)(you)變(bian)頻(pin)調速用電(dian)(dian)位(wei)器，可以根據(ju)操作(zuo)人員輸送頻(pin)率(lv)，向電(dian)(dian)機(ji)輸送指令(ling)信號(hao)，控(kong)制(zhi)電(dian)(dian)機(ji)運行速度(du)，并且在部(bu)分產品設(she)有(you)(you)工頻(pin)切(qie)換功能，以確(que)保(bao)變(bian)頻(pin)器出現(xian)故(gu)障時，可以通過裝(zhuang)置實現(xian)最低故(gu)障發生，減(jian)少設(she)備(bei)出現(xian)損壞次數。 

國家發(fa)改委啟動的十(shi)大重點(dian)節(jie)能(neng)(neng)工程之一(yi)就(jiu)是電機(ji)系統節(jie)能(neng)(neng)，并要求：推廣變(bian)(bian)頻(pin)調速節(jie)能(neng)(neng)技術，風機(ji)、水泵、壓縮機(ji)等通用機(ji)械(xie)(xie)系統采用變(bian)(bian)頻(pin)調速節(jie)能(neng)(neng)措施，工業(ye)機(ji)械(xie)(xie)采用交流電動機(ji)變(bian)(bian)頻(pin)調速技術；制定相關經濟(ji)激勵(li)政策、完善電機(ji)能(neng)(neng)效標準體系等配套措施；“十(shi)一(yi)五”期間，實現電機(ji)系統運行(xing)效率(lv)提高2個百(bai)分點(dian)，形成(cheng)年節(jie)電能(neng)(neng)力200億千瓦時。 

為(wei)推動(dong)全(quan)社會(hui)(hui)展開節能降(jiang)耗，緩解能源(yuan)(yuan)瓶(ping)頸的(de)制(zhi)約(yue)，建設節能型社會(hui)(hui)，國家發改委制(zhi)定了《節能中長期(qi)專項規劃(hua)》，并在2004年11月25日(ri)向全(quan)社會(hui)(hui)發布。該“規劃(hua)”明確指出：能源(yuan)(yuan)是(shi)戰略資源(yuan)(yuan)，是(shi)全(quan)面建設小康社會(hui)(hui)的(de)重要(yao)物質基礎，必須堅(jian)持節約(yue)優先。
