補(bu)(bu)償電(dian)(dian)(dian)(dian)(dian)容器組裝設在變電(dian)(dian)(dian)(dian)(dian)站站內(nei)母線上，可手動(dong)或分組自(zi)動(dong)補(bu)(bu)償。結合(he)電(dian)(dian)(dian)(dian)(dian)網(wang)實際情況，選擇按功率因數、電(dian)(dian)(dian)(dian)(dian)壓無(wu)功、電(dian)(dian)(dian)(dian)(dian)壓無(wu)功綜合(he)控(kong)(kong)(kong)制(zhi)或電(dian)(dian)(dian)(dian)(dian)壓無(wu)功綜合(he)控(kong)(kong)(kong)制(zhi)兼濾波等(deng)不同方式進行補(bu)(bu)償。動(dong)態無(wu)功補(bu)(bu)償由(you)可控(kong)(kong)(kong)硅控(kong)(kong)(kong)制(zhi)投(tou)切電(dian)(dian)(dian)(dian)(dian)容器，這種控(kong)(kong)(kong)制(zhi)方式反應(ying)速度(du)一(yi)般在20ms，投(tou)切時無(wu)充電(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)流和過電(dian)(dian)(dian)(dian)(dian)壓，但由(you)于可控(kong)(kong)(kong)硅有(you)自(zi)然導通電(dian)(dian)(dian)(dian)(dian)壓的(de)特性(xing)，電(dian)(dian)(dian)(dian)(dian)容器投(tou)切是會產生諧波。

智(zhi)能建筑中無功補償元器件的補償標準是什么

從技術原(yuan)理上講無(wu)功(gong)補(bu)償(chang)(chang)裝置是(shi)在電(dian)(dian)網中(zhong)呈(cheng)感(gan)性(xing)(xing)或容(rong)(rong)性(xing)(xing)的(de)元件(jian)，由(you)(you)(you)于(yu)(yu)(yu)目(mu)前我國中(zhong)低壓(ya)電(dian)(dian)網以架空線(xian)路為主且基(ji)本上帶感(gan)性(xing)(xing)負載，所(suo)以系統(tong)所(suo)采用的(de)無(wu)功(gong)補(bu)償(chang)(chang)裝置多數呈(cheng)容(rong)(rong)性(xing)(xing)，也就是(shi)說(shuo)它是(shi)由(you)(you)(you)電(dian)(dian)容(rong)(rong)器和相應的(de)附屬設施組成的(de)。由(you)(you)(you)于(yu)(yu)(yu)負荷多數集中(zhong)在配電(dian)(dian)網絡，所(suo)以多年來用于(yu)(yu)(yu)無(wu)功(gong)補(bu)償(chang)(chang)的(de)電(dian)(dian)容(rong)(rong)器組基(ji)本上安裝在電(dian)(dian)網的(de)中(zhong)壓(ya)側和低壓(ya)側，包括35 kV、10 kV和0.4 kV幾個電(dian)(dian)壓(ya)等級(ji)。從運行需(xu)要上說(shuo)，無(wu)功(gong)補(bu)償(chang)(chang)裝置由(you)(you)(you)電(dian)(dian)容(rong)(rong)器組、投切元件(jian)、檢(jian)測及(ji)保護元件(jian)組成。

電(dian)力電(dian)容(rong)器(qi)無功(gong)補償裝置的缺點(dian)有(you)：只能進行(xing)(xing)有(you)級調節(jie),不能進行(xing)(xing)平滑調節(jie);通風(feng)不良，一(yi)旦(dan)電(dian)容(rong)器(qi)運行(xing)(xing)溫度(du)高于(yu)70℃時，易發生(sheng)膨脹爆炸(zha)；電(dian)壓特(te)性不好，對短路穩定性差，切(qie)除后有(you)殘余電(dian)荷；無功(gong)補償精度(du)低(di)，易影響(xiang)補償效(xiao)果(guo)；補償電(dian)容(rong)器(qi)的運行(xing)(xing)管理困難及電(dian)容(rong)器(qi)安全運行(xing)(xing)的問題未受到重(zhong)視等(deng)。
