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售熱(re)潮,其功能(neng)全面特點是起到很(hen)大作(zuo)用(yong),不同功能(neng)迎合到市場不同用(yong)戶(hu)群體,迅速占據到各大市場空間。以下就來為大家全面介紹PLC變(bian)頻控制柜功能(neng)信息內(nei)容:
1、電源切換(huan)與(yu)保(bao)護(hu)功能,PLC變頻控制柜通常(chang)設(she)計有(you)短路(lu)器(qi)元(yuan)件,連(lian)接(jie)著進線電源,可(ke)以幫(bang)助(zhu)變頻設(she)備完成(cheng)電路(lu)通斷控制,并能夠在電路(lu)和(he)變頻器(qi)出現短路(lu)或是運行過(guo)載時(shi)給予保(bao)護(hu),解決(jue)設(she)備在運行中會發(fa)生電力輸送(song)安全問題,對操(cao)控人員人身安全起到保(bao)護(hu)。
2、變(bian)頻(pin)(pin)(pin)調速功(gong)能(neng),PLC變(bian)頻(pin)(pin)(pin)控制(zhi)柜(ju)面板上設(she)(she)有(you)變(bian)頻(pin)(pin)(pin)調速用電位器,可(ke)以(yi)根據操作人員輸送(song)頻(pin)(pin)(pin)率,向電機(ji)輸送(song)指令信(xin)號,控制(zhi)電機(ji)運行速度,并且在(zai)部分產品設(she)(she)有(you)工頻(pin)(pin)(pin)切換(huan)功(gong)能(neng),以(yi)確(que)保變(bian)頻(pin)(pin)(pin)器出現故障時,可(ke)以(yi)通過裝置實現最低故障發生,減少設(she)(she)備出現損壞次數。
國家(jia)發改委啟動的十(shi)大重點(dian)節(jie)能(neng)(neng)工程之一(yi)就是電(dian)機(ji)(ji)系統(tong)節(jie)能(neng)(neng),并要求:推廣變頻調(diao)(diao)速(su)節(jie)能(neng)(neng)技術,風機(ji)(ji)、水泵、壓縮機(ji)(ji)等通用(yong)機(ji)(ji)械(xie)(xie)系統(tong)采(cai)用(yong)變頻調(diao)(diao)速(su)節(jie)能(neng)(neng)措施,工業(ye)機(ji)(ji)械(xie)(xie)采(cai)用(yong)交流電(dian)動機(ji)(ji)變頻調(diao)(diao)速(su)技術;制定相關經濟激勵(li)政策、完善電(dian)機(ji)(ji)能(neng)(neng)效標(biao)準體系等配套(tao)措施;“十(shi)一(yi)五”期間,實(shi)現電(dian)機(ji)(ji)系統(tong)運行效率提高2個(ge)百分點(dian),形成年節(jie)電(dian)能(neng)(neng)力200億千瓦時(shi)。
為推動(dong)全社(she)會(hui)展開節能(neng)降(jiang)耗,緩解(jie)能(neng)源(yuan)瓶頸的制約,建(jian)設節能(neng)型社(she)會(hui),國家發(fa)改委制定了《節能(neng)中長(chang)期專項規劃(hua)》,并在2004年(nian)11月25日向全社(she)會(hui)發(fa)布。該“規劃(hua)”明確指(zhi)出(chu):能(neng)源(yuan)是(shi)戰略資源(yuan),是(shi)全面建(jian)設小康社(she)會(hui)的重要物質基礎,必須堅持節約優(you)先。
