動態補(bu)(bu)償(chang)和靜(jing)(jing)態補(bu)(bu)償(chang)的(de)(de)(de)主要區別是(shi)補(bu)(bu)償(chang)的(de)(de)(de)速(su)度(du)(du)動態的(de)(de)(de)很快，國標要求在(zai)2秒(miao)以內(nei)跟(gen)上負載(zai)(zai)的(de)(de)(de)變(bian)化(hua)，國外(wai)標準則更(geng)高，要求20mS，就是(shi)要在(zai)一個周波內(nei)跟(gen)上負載(zai)(zai)變(bian)化(hua)，這樣(yang)，負載(zai)(zai)需要無(wu)功(gong)的(de)(de)(de)時候，馬(ma)上就補(bu)(bu)償(chang)。不過動態的(de)(de)(de)價格超(chao)貴!靜(jing)(jing)態的(de)(de)(de)比較(jiao)慢(man)，國標修(xiu)改以后已經比原來(lai)的(de)(de)(de)快了很多，但是(shi)還是(shi)在(zai)15秒(miao)以上，就是(shi)說，負載(zai)(zai)變(bian)化(hua)后，至少(shao)要等15秒(miao)以后，靜(jing)(jing)態補(bu)(bu)償(chang)才開始動作(zuo)。但是(shi)靜(jing)(jing)態的(de)(de)(de)成熟可靠，價格低廉。介于動態與(yu)靜(jing)(jing)態之間的(de)(de)(de)，是(shi)快速(su)補(bu)(bu)償(chang)，反應速(su)度(du)(du)為2～10秒(miao)。 　　

安裝低(di)壓補償(chang)模組原理及作用(yong)

如(ru)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)磁(ci)元(yuan)件(jian)建立磁(ci)場占用的(de)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)能,電(dian)(dian)(dian)(dian)(dian)(dian)(dian)容(rong)器建立電(dian)(dian)(dian)(dian)(dian)(dian)(dian)場所占的(de)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)能.電(dian)(dian)(dian)(dian)(dian)(dian)(dian)流(liu)在(zai)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)感(gan)元(yuan)件(jian)中作(zuo)功時,電(dian)(dian)(dian)(dian)(dian)(dian)(dian)流(liu)滯后于電(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓90°.而電(dian)(dian)(dian)(dian)(dian)(dian)(dian)流(liu)在(zai)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)容(rong)元(yuan)件(jian)中作(zuo)功時,電(dian)(dian)(dian)(dian)(dian)(dian)(dian)流(liu)超前電(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓90°.在(zai)同一電(dian)(dian)(dian)(dian)(dian)(dian)(dian)路中,電(dian)(dian)(dian)(dian)(dian)(dian)(dian)感(gan)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)流(liu)與電(dian)(dian)(dian)(dian)(dian)(dian)(dian)容(rong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)流(liu)方向相(xiang)反,互差(cha)180°.如(ru)果在(zai)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)磁(ci)元(yuan)件(jian)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)路中有(you)比例地安裝(zhuang)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)容(rong)元(yuan)件(jian),使兩者(zhe)的(de)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)流(liu)相(xiang)互抵消(xiao),使電(dian)(dian)(dian)(dian)(dian)(dian)(dian)流(liu)的(de)矢量與電(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓矢量之(zhi)間的(de)夾角(jiao)縮小。
