為(wei)了保(bao)證電(dian)(dian)力電(dian)(dian)網(wang)運行(xing)的(de)穩定性和安(an)全性，都會安(an)裝了一些相關的(de)無(wu)功補(bu)(bu)償(chang)設備，其(qi)實(shi)無(wu)功補(bu)(bu)償(chang)在節電(dian)(dian)方面(mian)的(de)效果也是(shi)非(fei)常明顯的(de)，所以深受企業的(de)歡迎。下面(mian)就重點來分(fen)析一下無(wu)功補(bu)(bu)償(chang)措施(shi)的(de)優異(yi)性能(neng)。電(dian)(dian)網(wang)系(xi)統中被用(yong)到的(de)無(wu)功補(bu)(bu)償(chang)的(de)方式有(you)很(hen)多，包括集中補(bu)(bu)償(chang)、單臺電(dian)(dian)動機就地(di)補(bu)(bu)償(chang)和分(fen)組補(bu)(bu)償(chang)，每(mei)種補(bu)(bu)償(chang)方式都有(you)各自的(de)特點，使(shi)用(yong)的(de)時候也略有(you)不同(tong)。但是(shi)這些并(bing)不會影響(xiang)其(qi)優異(yi)的(de)使(shi)用(yong)效果，特別是(shi)在節電(dian)(dian)方面(mian)的(de)。

純電容無(wu)功補(bu)償(chang)元件的(de)基本常識

當控制指(zhi)令撤消時，觸(chu)發脈沖隨即消失，晶閘(zha)管零電(dian)(dian)(dian)流自(zi)然(ran)關斷(duan)。關斷(duan)后(hou)的電(dian)(dian)(dian)容器(qi)(qi)電(dian)(dian)(dian)壓為線(xian)路電(dian)(dian)(dian)壓交流峰值，必須由放電(dian)(dian)(dian)電(dian)(dian)(dian)阻盡(jin)快放電(dian)(dian)(dian)，以備電(dian)(dian)(dian)容器(qi)(qi)再次投(tou)入。元(yuan)器(qi)(qi)件(jian)可以選(xuan)(xuan)單(dan)項晶閘(zha)管反(fan)并聯或是雙向晶閘(zha)管，也可選(xuan)(xuan)適合容性負載的固態接觸(chu)器(qi)(qi)，這樣(yang)可以省(sheng)去過零觸(chu)發的脈沖電(dian)(dian)(dian)路，從而簡化線(xian)路，元(yuan)件(jian)的耐壓及電(dian)(dian)(dian)流要(yao)合理選(xuan)(xuan)擇，散熱(re)器(qi)(qi)及冷卻方式(shi)也要(yao)考慮周全(quan)。

技術特征：電(dian)壓優先：按電(dian)壓質量(liang)要(yao)求自(zi)(zi)動投切電(dian)容器(qi)(qi)，使(shi)母線電(dian)壓始(shi)終(zhong)處(chu)(chu)于(yu)規定范圍。自(zi)(zi)動補(bu)償：依據(ju)無功大小(xiao)自(zi)(zi)動投切電(dian)容器(qi)(qi)組(zu)，使(shi)系(xi)統不過壓、不過補(bu)、無功損耗始(shi)終(zhong)處(chu)(chu)于(yu) 小(xiao)的狀態(tai)。記(ji)錄(lu)監測：可自(zi)(zi)動或隨時調(diao)出(chu)監測數據(ju)、運行記(ji)錄(lu)、電(dian)壓合(he)格率統計表(biao)等 (選配)。
