低(di)壓集中(zhong)補(bu)償(chang)是(shi)指將低(di)壓電(dian)(dian)(dian)容(rong)器(qi)通過低(di)壓開關連(lian)接到配電(dian)(dian)(dian)變(bian)壓器(qi)低(di)壓母線側，以無功(gong)(gong)補(bu)償(chang)投切(qie)裝置(zhi)(zhi)作為控制(zhi)和保護裝置(zhi)(zhi)，根據低(di)壓母線上的無功(gong)(gong)負荷直接控制(zhi)電(dian)(dian)(dian)容(rong)器(qi)投切(qie)。電(dian)(dian)(dian)容(rong)器(qi)的投切(qie)是(shi)整組進行的，不能平(ping)滑調(diao)整。低(di)壓補(bu)償(chang)的優點(dian):接線簡(jian)單，運行維護工作量小，無功(gong)(gong)平(ping)衡，從而提高(gao)(gao)配電(dian)(dian)(dian)變(bian)壓器(qi)利(li)用(yong)(yong)率，降(jiang)低(di)網(wang)損，經濟性高(gao)(gao)，是(shi)目前無功(gong)(gong)補(bu)償(chang)常(chang)用(yong)(yong)的手段之一。
