    電梯能量回饋裝置節電效果

    電梯能量回饋設備根本原理
        電梯能量回饋裝置將電梯運轉過程中變頻器開釋到制動電阻的高壓直流廢電,經過能量回饋設備收回、整流、逆變、濾波后,構成新的再生電能回饋并回修建內的三相公共電網運用,然后使廢電再次運用到達節能和下降電梯機房溫度的作用。
       
    電梯能量回饋設備后的經濟效益和環保效益
         1.能量回饋設備轉化率超越了98%,并且不會污染電網。經實測同步電梯節電率可達30-48%,異步電梯20-30%。且速度越高,功率越大,載重越大,省電作用越好。并且原有制動電阻根本不再發熱,機房溫度下降,節約了機房降溫設備的置辦費和耗電量。
           一般用戶在機房內設備空調的功率約為4KW,一年按需求運轉天數300天,每天運轉12小時核算,一年即用電14400度。在許多地方,僅機房空調的置辦、耗電、維護等費用就是一個十分大的成本。并且小區的電梯不是同一時間都在發電,部分電梯處于發電時,另一些電梯會用掉這些電能。物業的總電表是計量外電網的用電電量,這樣就會使總表計量減少,向電力公司的繳費就會相應下降。
         2.電梯已經成為當今社會用電量中,僅次于空調的第二耗電大戶,占社區公共用電量的20%-30%左右。2016年年末我國電梯保有量突破了450萬臺,早已是國際電梯大國,市場份額占全球60%。電梯節能已成為我國社會節能的重要范疇。一部一般電梯每天用電大約在30-80度,依照每部電梯每天均勻耗電50度、每年運轉300天,全國在用數量400萬臺核算,每天電梯用電2億度,一年就是600億度!耗費的電能超越三峽一年發電量的三分之二,可見電梯耗電之巨!因而,實際中電梯節能就顯得十分有必要了。
     
    能量回饋設備后對電梯的影響
         1.徹底不會影響電梯的正常運轉。
            能量回饋設備時不會改動電梯原有控制體系的任何電路及線路,只需將輸入端并聯在電梯變頻器放電的高壓直流母線上,輸出端并聯接入380V供電開關即可。
            能量回饋設備截流收回電梯運轉時變頻器所開釋到大功率制動電阻上的高壓直流廢電,經過整流、逆變、濾波后,構成新的再生電能回饋并回修建內的三相公共電網運用,以此來到達電梯節能的作用,徹底不會影響電梯正常運用的。
            能量回饋設備針對電梯的維護在軟件和硬件進行了最大的優化規劃,在輸入端口選用全橋整流輸入,確保在DC電源正負接反的情況下依然能夠正常作業,回饋到電網的三相電源也無需知道相序,軟件會實時自動偵測相序并智能調整,所以在接線上徹底杜絕了因接錯線而導致設備作業不正常或影響電梯運轉。并且在電梯的直流放電和回饋三相電網銜接的線纜上別離串聯入了快速熔斷穩妥,若有反常發作,快速熔斷穩妥瞬間會把回饋設備和電梯徹底斷開,保證了電梯與回饋設備的設備安全。
         2.停電后發電機對能量回饋設備是否會有影響
            沒有影響。電梯停電后,能量回饋設備會智能判別電網斷電,當即中止輸出。當發電機發電時,能判別發電設備電源的頻率與相位,使發電機的負載減輕、發熱量減小,既到達節能作用又延長了發電機的運用壽命。
         3.困人救援,手動滑梯時是否會有影響
            沒有影響。電梯困人救援時,有必要斷電,這時設備和電梯都沒有電源,處于中止狀況,即便直流母線電壓升高,設備也不會作業。 
         4.是否影響電梯的運轉環境
            有影響,更優質!能量回饋設備是將電梯運轉中放掉的廢電智能收回轉換為新的電能回來修建電網再次運用,制動電阻減少了發熱,整個控制柜的溫度趨于常溫,大大下降了變頻器的作業溫度,極大的改進了電梯控制體系的運轉環境,然后延長了控制體系及電梯運用壽命。機房也不再運用空調等散熱設備,能夠節約機房空諧和散熱設備的耗電量,節能環保,使整個體系更省電。

    是否影響電梯年檢 :  
        不會影響。
         該設備與電梯的銜接為主開關的三相溝通端子及溝通變頻器的直流母線端子,未參加電梯運轉過程中的控制。摘自《國家電梯質量監督查驗中心》的檢測陳述(NO: WT NET 16-024)第3頁2項3條:檢測成果。

    產品運用
        新梯配套、舊梯晉級。
         電梯能量回饋裝置設備可適用于曳引機為國標380V的一切品牌筆直電梯節能晉級。(自帶回饋體系的超高速電梯在外)經實測同步電梯節電率可達30-40%,異步電梯15-25%。一起本產品也適用于港口起重機的節能改造。
