為了(le)保證電(dian)力電(dian)網(wang)運行的(de)(de)(de)(de)(de)穩定(ding)性和安全性，都(dou)會(hui)安裝了(le)一些相關的(de)(de)(de)(de)(de)無功補(bu)(bu)償(chang)(chang)(chang)設備，其實無功補(bu)(bu)償(chang)(chang)(chang)在節(jie)(jie)電(dian)方(fang)(fang)面(mian)的(de)(de)(de)(de)(de)效果(guo)也(ye)是非常明顯的(de)(de)(de)(de)(de)，所(suo)以(yi)深受企業的(de)(de)(de)(de)(de)歡迎。下面(mian)就重(zhong)點(dian)來分(fen)析一下無功補(bu)(bu)償(chang)(chang)(chang)措施的(de)(de)(de)(de)(de)優異性能。電(dian)網(wang)系統中被用(yong)到的(de)(de)(de)(de)(de)無功補(bu)(bu)償(chang)(chang)(chang)的(de)(de)(de)(de)(de)方(fang)(fang)式有(you)(you)很多(duo)，包(bao)括集中補(bu)(bu)償(chang)(chang)(chang)、單臺電(dian)動機(ji)就地補(bu)(bu)償(chang)(chang)(chang)和分(fen)組補(bu)(bu)償(chang)(chang)(chang)，每(mei)種補(bu)(bu)償(chang)(chang)(chang)方(fang)(fang)式都(dou)有(you)(you)各(ge)自的(de)(de)(de)(de)(de)特點(dian)，使(shi)用(yong)的(de)(de)(de)(de)(de)時候(hou)也(ye)略有(you)(you)不(bu)同(tong)。但是這些并(bing)不(bu)會(hui)影(ying)響其優異的(de)(de)(de)(de)(de)使(shi)用(yong)效果(guo)，特別(bie)是在節(jie)(jie)電(dian)方(fang)(fang)面(mian)的(de)(de)(de)(de)(de)。

純電容無功(gong)補償(chang)元(yuan)件(jian)的基(ji)本常識

當(dang)控制指令撤消時(shi)，觸發(fa)(fa)脈(mo)沖隨即消失，晶(jing)閘(zha)管(guan)零電(dian)(dian)(dian)(dian)(dian)流自(zi)然關斷。關斷后的(de)電(dian)(dian)(dian)(dian)(dian)容(rong)器(qi)電(dian)(dian)(dian)(dian)(dian)壓(ya)為線(xian)路電(dian)(dian)(dian)(dian)(dian)壓(ya)交(jiao)流峰值，必(bi)須由放電(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)阻盡快放電(dian)(dian)(dian)(dian)(dian)，以(yi)備電(dian)(dian)(dian)(dian)(dian)容(rong)器(qi)再次投入。元器(qi)件可以(yi)選(xuan)單項晶(jing)閘(zha)管(guan)反并聯或(huo)是雙向晶(jing)閘(zha)管(guan)，也(ye)可選(xuan)適合(he)容(rong)性負載的(de)固態(tai)接觸器(qi)，這樣(yang)可以(yi)省去過零觸發(fa)(fa)的(de)脈(mo)沖電(dian)(dian)(dian)(dian)(dian)路，從而簡化(hua)線(xian)路，元件的(de)耐壓(ya)及電(dian)(dian)(dian)(dian)(dian)流要合(he)理(li)選(xuan)擇，散熱(re)器(qi)及冷卻(que)方(fang)式也(ye)要考慮(lv)周全。

技術特征：電(dian)壓(ya)優先：按電(dian)壓(ya)質量要求自(zi)動投切(qie)電(dian)容器，使母線電(dian)壓(ya)始終處于規定范(fan)圍。自(zi)動補償：依(yi)據無功大小自(zi)動投切(qie)電(dian)容器組，使系統不(bu)過壓(ya)、不(bu)過補、無功損(sun)耗始終處于 小的狀態。記(ji)錄(lu)監(jian)測：可自(zi)動或隨時調出監(jian)測數據、運行記(ji)錄(lu)、電(dian)壓(ya)合格率(lv)統計表等 (選(xuan)配)。
