電(dian)力系統濾(lv)波補償模組如何選擇低壓防爆電(dian)容器匹配的無功控制器

對具有(you)多段串聯的電容(rong)(rong)器組，在(zai)人接(jie)觸之前(qian)還應將串聯段連接(jie)點對地短路放(fang)(fang)電。電容(rong)(rong)器如(ru)果(guo)是(shi)內(nei)部斷(duan)(duan)線，熔(rong)(rong)絲熔(rong)(rong)斷(duan)(duan)或引線接(jie)觸不(bu)良，其兩極間還可能有(you)殘(can)余電荷，這樣(yang)在(zai)自動放(fang)(fang)電或人工放(fang)(fang)電時，它的殘(can)余電荷是(shi)不(bu)會被(bei)放(fang)(fang)掉的。所以，運行或檢修人員在(zai)接(jie)觸故障電容(rong)(rong)器前(qian)，還應戴好絕緣手(shou)套，用短路線短接(jie)故障電容(rong)(rong)器的兩極，使其放(fang)(fang)電。

這類(lei)調壓(ya)(ya)功(gong)(gong)效(xiao)隨線(xian)路(lu)負荷的(de)轉變(bian)而轉變(bian)，具備(bei)自(zi)(zi)主調整的(de)作用(yong)。串聯電(dian)(dian)力電(dian)(dian)容(rong)器所(suo)造成的(de)無(wu)功(gong)(gong)負荷，也提升了電(dian)(dian)網(wang)的(de)無(wu)功(gong)(gong)功(gong)(gong)率開關電(dian)(dian)源，可(ke)改進電(dian)(dian)網(wang)的(de)電(dian)(dian)壓(ya)(ya)水準。串聯電(dian)(dian)容(rong)器能使線(xian)路(lu)受(shou)端(duan)電(dian)(dian)機造成自(zi)(zi)勵磁調節器狀況，在設計方案、應用(yong)時，需小試控投采用(yong)防范措施。
