電容補償柜的作用有哪些呢?電容柜補償柜又稱電容柜,是一款無功補償裝置。
在我國經(jing)濟發展的浸提,能(neng)(neng)源供(gong)應充足成(cheng)為一(yi)個重(zhong)(zhong)要(yao)(yao)(yao)條件,而電(dian)力是主(zhu)要(yao)(yao)(yao)的能(neng)(neng)源,因(yin)此節(jie)(jie)電(dian)顯得(de)非常(chang)重(zhong)(zhong)要(yao)(yao)(yao),節(jie)(jie)電(dian)已經(jing)成(cheng)為提高能(neng)(neng)效,降低(di)能(neng)(neng)耗的重(zhong)(zhong)要(yao)(yao)(yao)途(tu)徑。為了(le)改(gai)善電(dian)網功(gong)率因(yin)數(shu)(shu)低(di)下帶來的能(neng)(neng)源浪費和這(zhe)些不利(li)供(gong)電(dian)生產(chan)的因(yin)素,必須(xu)使(shi)電(dian)網功(gong)率因(yin)數(shu)(shu)得(de)到有效的提高。目前,許多企業(ye)采用電(dian)容(rong)補(bu)償(chang)柜來補(bu)償(chang)無(wu)功(gong)功(gong)率。
電(dian)(dian)容補償柜(ju)是利用(yong)電(dian)(dian)容的(de)(de)容抗(kang)來(lai)補償電(dian)(dian)感負載的(de)(de)感抗(kang),減少無功(gong)電(dian)(dian)流(liu)(liu),補償發電(dian)(dian)機無功(gong)電(dian)(dian)流(liu)(liu)、減輕發電(dian)(dian)機工(gong)作負荷,增(zeng)加發電(dian)(dian)機可(ke)使用(yong)容量。補償無功(gong)后可(ke)以提高電(dian)(dian)壓、降低線損、減少電(dian)(dian)費(fei)支出、節約能(neng)源、增(zeng)加電(dian)(dian)網有功(gong)容量傳輸(shu)、提高設備的(de)(de)使用(yong)效率(lv),很大程度上(shang)減少企業的(de)(de)用(yong)電(dian)(dian)量、節省工(gong)業電(dian)(dian)力,提高發供電(dian)(dian)設備的(de)(de)供電(dian)(dian)質量和供電(dian)(dian)能(neng)力。
中國經(jing)濟能(neng)(neng)否保持快速增長,一個重要(yao)的(de)先決條件就是(shi)能(neng)(neng)源(yuan)供應(ying)的(de)充足,而電力是(shi)主要(yao)的(de)能(neng)(neng)源(yuan),因(yin)此節電顯得非常重要(yao),節電已經(jing)成(cheng)為提高能(neng)(neng)效,降低(di)能(neng)(neng)耗(hao)的(de)重要(yao)途徑。目前,許多企業采用電容補(bu)償(chang)柜來補(bu)償(chang)無(wu)功(gong)功(gong)率。
電容補償(chang)柜的作(zuo)用是(shi)對線(xian)路(lu)進行無功補償(chang),改善線(xian)路(lu)功率因數(shu)。
通過(guo)檢測裝置監測線路的功(gong)率(lv)因數,當低于設(she)定(ding)(ding)值(zhi)時,接觸器(qi)吸合,使電(dian)容器(qi)并(bing)聯入線路中,根據實際情況自(zi)動調整(zheng)電(dian)容器(qi)并(bing)入線路的多少(shao)。當達到設(she)定(ding)(ding)值(zhi)時,停止并(bing)入。當線路感性負載減少(shao)時,功(gong)率(lv)因數超(chao)前,此時線路自(zi)動減少(shao)并(bing)入的電(dian)容器(qi)容量,以(yi)達到設(she)定(ding)(ding)值(zhi)。
線路(lu)中(zhong)(zhong)有大量的(de)感性負載時(shi),電(dian)(dian)(dian)(dian)路(lu)的(de)功(gong)率(lv)因素(Cos ∮)下降(jiang)(jiang),用電(dian)(dian)(dian)(dian)效率(lv)降(jiang)(jiang)低,這(zhe)就需要在電(dian)(dian)(dian)(dian)路(lu)中(zhong)(zhong)并入(ru)電(dian)(dian)(dian)(dian)容器,由電(dian)(dian)(dian)(dian)容器提供(gong)超前(qian)90度的(de)電(dian)(dian)(dian)(dian)路(lu)來(lai)彌(mi)補(bu)滯后(hou)的(de)電(dian)(dian)(dian)(dian)流以達到提高和改善電(dian)(dian)(dian)(dian)路(lu)的(de)功(gong)率(lv)因素,這(zhe)就是(shi)工礦(kuang)企業需要安裝電(dian)(dian)(dian)(dian)容柜的(de)作用。
在電容(rong)柜(ju)中,有自(zi)(zi)動(dong)采集電路(lu)工(gong)作狀態的裝(zhuang)置,當功率(lv)因(yin)素偏低時,自(zi)(zi)動(dong)啟動(dong)補償裝(zhuang)置,將(jiang)電容(rong)接入,當電路(lu)中功率(lv)因(yin)素高時,自(zi)(zi)動(dong)切斷電容(rong)的接入以達(da)到自(zi)(zi)動(dong)補償的目的。
電容補償(chang)柜(ju)的省(sheng)電作(zuo)用
在(zai)電(dian)力(li)變(bian)壓(ya)器的(de)(de)(de)低壓(ya)端并聯電(dian)容(rong)器,利用(yong)(yong)電(dian)容(rong)電(dian)流超相(xiang)位前產(chan)生的(de)(de)(de)無功(gong)功(gong)率(lv),補(bu)償電(dian)感性(xing)負載電(dian)流相(xiang)位落(luo)后(hou)產(chan)生的(de)(de)(de)無功(gong)功(gong)率(lv)(相(xiang)位補(bu)償),防止感性(xing)無功(gong)功(gong)率(lv)經過電(dian)力(li)變(bian)壓(ya)器向高壓(ya)線路反饋,消除了感性(xing)無功(gong)功(gong)率(lv)在(zai)高壓(ya)線路流動時產(chan)生的(de)(de)(de)熱量(liang)(即線路壓(ya)降做功(gong)熱),因(yin)而減少了高壓(ya)線路的(de)(de)(de)線路損(sun)耗,這(zhe)就(jiu)是電(dian)容(rong)補(bu)償柜的(de)(de)(de)省電(dian)作用(yong)(yong)。
