光纖無功補償元件補償原(yuan)理與優缺點

根據(ju)目前國內設(she)備(bei)制造情況，對于10kV電(dian)(dian)容(rong)器(qi)(qi)，斷路器(qi)(qi)允許(xu)的(de)配(pei)置容(rong)量(liang)為10000kvar，氧化(hua)鋅(xin)避雷器(qi)(qi)允許(xu)的(de)配(pei)置容(rong)量(liang)為8000kvar，這些(xie)是(shi)防(fang)止電(dian)(dian)容(rong)器(qi)(qi)爆(bao)炸(zha)的(de) 大允許(xu)電(dian)(dian)容(rong)器(qi)(qi)并聯(lian)容(rong)量(liang)，但根據(ju)一些(xie)設(she)計重(zhong)工(gong)(gong)業和(he)大型(xing)化(hua)工(gong)(gong)企業設(she)計院的(de)習慣做(zuo)法，10kV電(dian)(dian)容(rong)器(qi)(qi)的(de)分(fen)組容(rong)量(liang)一般為2000kvar～3000kvar。為了節約設(she)備(bei)、方便操(cao)作，宜減少分(fen)組，加大分(fen)組容(rong)量(liang)。

體積小(xiao)、重(zhong)量輕：由于(yu)采用(yong)金屬化聚(ju)丙烯膜材料作(zuo)為介質(zhi)，  體積、重(zhong)量僅(jin)為老產品的(de)1/4和1/5。損耗低(di)：實(shi)際值低(di)于(yu)0.1%，所以(yi)電(dian)容器自身的(de)能耗低(di)，發(fa)熱少、溫升低(di)、工作(zuo)壽命長、節(jie)能效果佳。優良的(de)自愈性能： 過(guo)電(dian)壓所造(zao)成的(de)介質(zhi)局部擊(ji)穿能迅(xun)速自愈，恢復(fu)正常工作(zuo)，使可靠(kao)性大為提高。
