大連控制柜、變頻控制箱和大連PLC變頻控制柜出現在市場(chang)(chang)(chang)中引起銷售熱潮，其功能全面特點是起到(dao)(dao)很大作用，不同(tong)功能迎合到(dao)(dao)市場(chang)(chang)(chang)不同(tong)用戶(hu)群體，迅速占據到(dao)(dao)各(ge)大市場(chang)(chang)(chang)空間。以下就來為大家全面介紹PLC變頻(pin)控制柜功能信息(xi)內容： 

1、電(dian)源切(qie)換與保護(hu)功能(neng)，PLC變(bian)頻控制柜通常設(she)計有(you)短路器元(yuan)件，連接著進(jin)線電(dian)源，可以幫助變(bian)頻設(she)備(bei)完成電(dian)路通斷控制，并能(neng)夠在(zai)電(dian)路和(he)變(bian)頻器出(chu)現短路或(huo)是(shi)運行過載時給(gei)予(yu)保護(hu)，解決設(she)備(bei)在(zai)運行中會(hui)發(fa)生電(dian)力輸送安(an)全問題，對操控人員(yuan)人身安(an)全起到(dao)保護(hu)。 

2、變頻調(diao)速功(gong)能，PLC變頻控制(zhi)柜面(mian)板上設有變頻調(diao)速用電(dian)位器，可以根據(ju)操(cao)作人(ren)員(yuan)輸送頻率，向(xiang)電(dian)機輸送指令信號，控制(zhi)電(dian)機運行速度(du)，并且在部分產品設有工頻切換功(gong)能，以確保(bao)變頻器出現(xian)故(gu)障(zhang)時，可以通過(guo)裝置實現(xian)最(zui)低(di)故(gu)障(zhang)發生(sheng)，減少設備出現(xian)損壞次數。 

國(guo)家發(fa)改委啟(qi)動的十(shi)大重點節(jie)能(neng)(neng)(neng)工程之一就是(shi)電(dian)(dian)機(ji)系(xi)(xi)統(tong)節(jie)能(neng)(neng)(neng)，并要求：推(tui)廣變(bian)頻調(diao)速節(jie)能(neng)(neng)(neng)技(ji)術，風機(ji)、水泵、壓縮(suo)機(ji)等(deng)通(tong)用機(ji)械系(xi)(xi)統(tong)采(cai)用變(bian)頻調(diao)速節(jie)能(neng)(neng)(neng)措施(shi)，工業機(ji)械采(cai)用交流電(dian)(dian)動機(ji)變(bian)頻調(diao)速技(ji)術；制定相(xiang)關經濟激勵政策(ce)、完善電(dian)(dian)機(ji)能(neng)(neng)(neng)效標準(zhun)體系(xi)(xi)等(deng)配(pei)套措施(shi)；“十(shi)一五”期間，實現電(dian)(dian)機(ji)系(xi)(xi)統(tong)運行效率提高2個百分點，形成(cheng)年節(jie)電(dian)(dian)能(neng)(neng)(neng)力200億千瓦(wa)時。 

為(wei)推動全社(she)會展開節能(neng)(neng)降耗，緩解能(neng)(neng)源(yuan)瓶頸的(de)制約，建(jian)設(she)節能(neng)(neng)型社(she)會，國(guo)家發改委制定了《節能(neng)(neng)中長期(qi)專項(xiang)規劃》，并在(zai)2004年(nian)11月25日向(xiang)全社(she)會發布。該“規劃”明確(que)指出：能(neng)(neng)源(yuan)是(shi)戰略資源(yuan)，是(shi)全面建(jian)設(she)小(xiao)康(kang)社(she)會的(de)重要物質基礎，必須堅持節約優先。
