無功電表是不是不如有功電表
2024-01-10 790
?無(wu)(wu)(wu)功(gong)電(dian)(dian)(dian)表是(shi)一(yi)種(zhong)專門(men)用于記錄無(wu)(wu)(wu)功(gong)電(dian)(dian)(dian)能的設備(bei)。無(wu)(wu)(wu)功(gong)電(dian)(dian)(dian)能是(shi)指當電(dian)(dian)(dian)器(qi)(qi)裝置(zhi)(zhi)進(jin)行(xing)能量轉(zhuan)(zhuan)(zhuan)換(huan)(huan)時，需(xu)(xu)要(yao)(yao)先建立(li)(li)一(yi)個(ge)轉(zhuan)(zhuan)(zhuan)換(huan)(huan)環境，如(ru)電(dian)(dian)(dian)動機、變壓器(qi)(qi)等需(xu)(xu)要(yao)(yao)建立(li)(li)磁場進(jin)行(xing)能量轉(zhuan)(zhuan)(zhuan)換(huan)(huan)，還有(you)一(yi)些電(dian)(dian)(dian)器(qi)(qi)裝置(zhi)(zhi)需(xu)(xu)要(yao)(yao)先建立(li)(li)一(yi)個(ge)電(dian)(dian)(dian)場才(cai)能進(jin)行(xing)能量轉(zhuan)(zhuan)(zhuan)換(huan)(huan)。這些建立(li)(li)磁場和電(dian)(dian)(dian)場所需(xu)(xu)的電(dian)(dian)(dian)能都是(shi)無(wu)(wu)(wu)功(gong)電(dian)(dian)(dian)能。???????無(wu)(wu)(wu)功(gong)電(dian)(dian)(dian)能在(zai)電(dian)(dian)(dian)器(qi)(qi)裝置(zhi)(zhi)本(ben)身(shen)中(zhong)并(bing)不(bu)消耗能量，但會(hui)在(zai)電(dian)(dian)(dian)器(qi)(qi)線路中(zhong)產生無(wu)(wu)(wu)功(gong)電(dian)(dian)(dian)流(liu)(liu)。這種(zhong)無(wu)(wu)(wu)功(gong)電(dian)(dian)(dian)流(liu)(liu)在(zai)線路中(zhong)會(hui)產生一(yi)定的損(sun)耗，雖然它不(bu)會(hui)像有(you)功(gong)電(dian)(dian)(dian)流(liu)(liu)那樣直接導致(zhi)電(dian)(dian)(dian)能...

電表是怎么實現單計多控的
2024-01-09 814
????????電(dian)表(biao)的(de)(de)接線一(yi)(yi)(yi)般為三相四線或單相兩線，每條相線都有一(yi)(yi)(yi)個(ge)(ge)(ge)電(dian)流互感器和一(yi)(yi)(yi)個(ge)(ge)(ge)電(dian)壓互感器。在單相電(dian)路中，一(yi)(yi)(yi)個(ge)(ge)(ge)電(dian)表(biao)最(zui)多(duo)(duo)只能接兩個(ge)(ge)(ge)控(kong)開(kai)(kai)，而在三相電(dian)路中，一(yi)(yi)(yi)個(ge)(ge)(ge)電(dian)表(biao)最(zui)多(duo)(duo)可以接六個(ge)(ge)(ge)控(kong)開(kai)(kai)。這里的(de)(de)最(zui)多(duo)(duo)數(shu)量是建(jian)立在控(kong)開(kai)(kai)功率(lv)(lv)較小的(de)(de)情(qing)況下。如果控(kong)開(kai)(kai)功率(lv)(lv)較大，那么一(yi)(yi)(yi)個(ge)(ge)(ge)電(dian)表(biao)便(bian)無法支持(chi)過多(duo)(duo)的(de)(de)控(kong)開(kai)(kai)接入。在實際應用中，我們需要根據實際情(qing)況來選擇控(kong)開(kai)(kai)的(de)(de)數(shu)量和功率(lv)(lv)。???????在校園中，電(dian)表(biao)的(de)(de)控(kong)制方式對于電(dian)器的(de)(de)使用和管理至(zhi)...
