高壓固態軟啟動柜和水阻柜對比有哪些優點

相(xiang)對于水阻柜而(er)(er)言，高壓(ya)(ya)固態軟(ruan)啟(qi)動柜具有(you)以下一(yi)些優點： 1. 穩(wen)定(ding)性好：高壓(ya)(ya)固態軟(ruan)啟(qi)動柜采用半導體器件，啟(qi)停過程平滑，不(bu)會引起電(dian)網電(dian)壓(ya)(ya)的波動和(he)電(dian)機振(zhen)動，對電(dian)網和(he)設備的穩(wen)定(ding)性影響(xiang)小，故而(er)(er)相(xiang)對穩(wen)定(ding)性較(jiao)高。

高壓水阻啟動柜原理介紹

繞線電(dian)機(ji)液體電(dian)阻(zu)起動(dong)(dong)柜也就是(shi)高壓水(shui)阻(zu)啟動(dong)(dong)柜利用這一原理，在被控繞線式電(dian)動(dong)(dong)機(ji)的(de)(de)轉(zhuan)子回路(lu)中串(chuan)入(ru)特殊配制的(de)(de)電(dian)解(jie)液作為電(dian)阻(zu)，并(bing)通過調整電(dian)解(jie)液的(de)(de)濃(nong)度及改變兩極板(ban)的(de)(de)距離使串(chuan)入(ru)電(dian)阻(zu)阻(zu)值在起動(dong)(dong)過程中始終滿足電(dian)機(ji)機(ji)械(xie)特性……

怎樣選用高壓無功補償裝置

現(xian)在(zai)常(chang)用的高(gao)壓無(wu)功(gong)補(bu)償(chang)(chang)裝(zhuang)置(zhi)通常(chang)是裝(zhuang)在(zai)一(yi)個獨立(li)的電(dian)(dian)柜內，因此也(ye)叫無(wu)功(gong)補(bu)償(chang)(chang)柜。無(wu)功(gong)補(bu)償(chang)(chang)裝(zhuang)置(zhi)按補(bu)償(chang)(chang)負荷的電(dian)(dian)壓可以分為高(gao)壓無(wu)功(gong)補(bu)償(chang)(chang)裝(zhuang)置(zhi)和低壓無(wu)功(gong)補(bu)償(chang)(chang)裝(zhuang)置(zhi)，比如一(yi)個企業的變壓器(qi)出(chu)線電(dian)(dian)壓10KV,所帶(dai)負荷有高(gao)壓電(dian)(dian)機、變……

高壓電容補償柜的原理

在(zai)交流(liu)(liu)(liu)電(dian)(dian)(dian)(dian)路(lu)中(zhong)，電(dian)(dian)(dian)(dian)阻(zu)、電(dian)(dian)(dian)(dian)感、電(dian)(dian)(dian)(dian)容元(yuan)件的電(dian)(dian)(dian)(dian)壓(ya)(ya)、電(dian)(dian)(dian)(dian)流(liu)(liu)(liu)的相(xiang)位特點為(wei)在(zai)純電(dian)(dian)(dian)(dian)阻(zu)電(dian)(dian)(dian)(dian)路(lu)中(zhong)，電(dian)(dian)(dian)(dian)流(liu)(liu)(liu)與(yu)電(dian)(dian)(dian)(dian)壓(ya)(ya)同相(xiang)位；在(zai)純電(dian)(dian)(dian)(dian)容電(dian)(dian)(dian)(dian)路(lu)中(zhong)電(dian)(dian)(dian)(dian)流(liu)(liu)(liu)超前(qian)電(dian)(dian)(dian)(dian)壓(ya)(ya)90；在(zai)純電(dian)(dian)(dian)(dian)感電(dian)(dian)(dian)(dian)路(lu)中(zhong)電(dian)(dian)(dian)(dian)流(liu)(liu)(liu)滯后電(dian)(dian)(dian)(dian)壓(ya)(ya)90。從供電(dian)(dian)(dian)(dian)角度，理想(xiang)的負(fu)載是P與(yu)S相(xiang)等(deng)，功率因數cosφ為(wei)……
