ABB低壓電容補償柜的作用及組成結構解析
ABB低(di)壓(ya)(ya)電容補(bu)償柜主(zhu)要(yao)作用是提高電力系(xi)統(tong)的(de)功(gong)(gong)率因數,降(jiang)低(di)系(xi)統(tong)的(de)無(wu)功(gong)(gong)功(gong)(gong)率,從而優化(hua)電能(neng)的(de)使(shi)用。其主(zhu)要(yao)功(gong)(gong)能(neng)在(zai)于補(bu)償無(wu)功(gong)(gong)功(gong)(gong)率,改善功(gong)(gong)率因數,穩定(ding)系(xi)統(tong)電壓(ya)(ya),減少(shao)電能(neng)浪費。
以下(xia)是對ABB低壓(ya)電(dian)容柜的基礎介(jie)紹(shao):
⑴作用:
ABB低壓(ya)(ya)電(dian)(dian)容柜在正(zheng)常配電(dian)(dian)系統運行中通(tong)過自動(dong)分步(bu)投(tou)切并(bing)聯在配電(dian)(dian)變(bian)壓(ya)(ya)器1kV及以(yi)下(xia)母線(xian)的(de)電(dian)(dian)容器組,提供容性(xing)無功(gong)功(gong)率,補(bu)償(chang)感性(xing)無功(gong)功(gong)率,從而減少(shao)電(dian)(dian)壓(ya)(ya)和(he)無功(gong)功(gong)率波動(dong),降低線(xian)路損耗,提高變(bian)壓(ya)(ya)器傳(chuan)輸容量(liang),提高電(dian)(dian)力(li)傳(chuan)輸效率。同時,它(ta)具備負荷(he)監測功(gong)能,實(shi)時監測電(dian)(dian)網運行狀況,實(shi)現無功(gong)補(bu)償(chang)和(he)配電(dian)(dian)監測的(de)一體化。
⑵結構:
ABB低(di)壓(ya)電(dian)(dian)容(rong)補(bu)償裝(zhuang)置通常包括電(dian)(dian)抗器(qi)、電(dian)(dian)容(rong)器(qi)、隔離開(kai)關、熔(rong)斷(duan)器(qi)、接(jie)觸器(qi)、電(dian)(dian)流(liu)互感(gan)器(qi)、快熔(rong)等二次(ci)元件。一個典型的(de)低(di)壓(ya)電(dian)(dian)容(rong)補(bu)償柜(ju)包括電(dian)(dian)抗器(qi)、電(dian)(dian)容(rong)器(qi)、接(jie)觸器(qi)、熔(rong)斷(duan)器(qi)等組件。通過監測進線柜(ju)電(dian)(dian)壓(ya)和(he)電(dian)(dian)流(liu)的(de)相位差,控(kong)制器(qi)輸出控(kong)制信號,控(kong)制交流(liu)接(jie)觸器(qi)的(de)閉合和(he)斷(duan)開(kai),實現(xian)電(dian)(dian)容(rong)器(qi)的(de)投入和(he)退出。
⑶使用條件:
最高運行電壓(ya)≤1.1Un;
最大過載(zai)電流≤1.31 n;
周圍環(huan)境(jing)溫度-25~+45℃;
室內(nei)相對濕(shi)度不超過90% (溫(wen)度為25℃時);
安(an)裝地點海拔高度不超(chao)過2000m;
無劇(ju)烈振動,垂直傾斜度不超過5度;
無導電(dian)性塵埃、火災、爆炸危險;
無(wu)足以腐蝕金屬和破壞(huai)絕(jue)緣的氣體。
ABB低壓電容補償柜可分為自動補償裝置和動態補償裝置,根據補償對象的不同。在選擇電容補償裝置時,需要考慮系統和負載的性質、大小、阻抗特性、運行方式等多方面因素,以上是得潤電氣對電容(rong)柜(ju)基礎知識的(de)簡要梳理。
