經常做(zuo)項(xiang)目施工的(de)朋(peng)友(you)會問(wen)到弱電、強(qiang)電有什么(me)(me)(me)區別。弱電指的(de)是(shi)(shi)什么(me)(me)(me)？強(qiang)電指的(de)是(shi)(shi)什么(me)(me)(me)？今天(tian)華思特小編帶您了(le)解下弱電、強(qiang)電。 

什么是弱電？

弱電一(yi)般(ban)(ban)是(shi)指直流(liu)電路(lu)或音頻、視頻線(xian)路(lu)、網絡(luo)線(xian)路(lu)、電話(hua)線(xian)路(lu)，直流(liu)電壓一(yi)般(ban)(ban)在36V以(yi)內。家(jia)用電(dian)器(qi)中(zhong)的(de)電(dian)話、電(dian)腦、電(dian)視機(ji)的(de)信號(hao)輸(shu)入（有(you)線電(dian)視線路）、音響設備（輸(shu)出(chu)端線路）等用電(dian)器(qi)均(jun)為弱電(dian)電(dian)氣設備。 

什么是強電？

強電(dian)(dian)指(zhi)電(dian)(dian)工(gong)領域的電(dian)(dian)力部分。強電(dian)(dian)一般指(zhi)交流電(dian)(dian)電(dian)(dian)壓在 24V以上(shang)。如家庭中的(de)電(dian)(dian)(dian)燈、插座等(deng)，電(dian)(dian)(dian)壓在 110～220V。家用電(dian)(dian)(dian)氣中的(de)照(zhao)明燈具、電(dian)(dian)(dian)冰箱(xiang)、電(dian)(dian)(dian)視機、音響設(she)備（輸入(ru)端(duan)）等(deng)用電(dian)(dian)(dian)器均為強(qiang)電(dian)(dian)(dian)電(dian)(dian)(dian)氣設(she)備。是相對于弱電(dian)(dian)(dian)而言的(de)。

一般來說強電(dian)(dian)的處(chu)理對(dui)象(xiang)是能(neng)源（電(dian)(dian)力），其(qi)特(te)點是電(dian)(dian)壓高(gao)、電(dian)(dian)流大、功率大、頻率低，主要考慮的問(wen)題是減少損耗、提高(gao)效率。

弱(ruo)電(dian)的(de)處(chu)理對象主要是信(xin)(xin)息(xi)，即信(xin)(xin)息(xi)的(de)傳送(song)和控制，其特點是電(dian)壓低、電(dian)流小、功率小、頻率高，主要考(kao)慮的(de)是信(xin)(xin)息(xi)傳送(song)的(de)效果問(wen)題，如信(xin)(xin)息(xi)傳送(song)的(de)保真度、速(su)度、廣(guang)度、可(ke)靠(kao)性。一(yi)般來說(shuo)，弱(ruo)電(dian)工(gong)(gong)程(cheng)(cheng)(cheng)包括電(dian)視工(gong)(gong)程(cheng)(cheng)(cheng)、通信(xin)(xin)工(gong)(gong)程(cheng)(cheng)(cheng)、消防(fang)工(gong)(gong)程(cheng)(cheng)(cheng)、保安工(gong)(gong)程(cheng)(cheng)(cheng)、影像工(gong)(gong)程(cheng)(cheng)(cheng)等等和為上述工(gong)(gong)程(cheng)(cheng)(cheng)服務的(de)綜合布(bu)線工(gong)(gong)程(cheng)(cheng)(cheng)。 

弱電和強電的區別

1、交流頻率不(bu)同

強電的頻率一(yi)般是50Hz，稱"工頻(pin)"，意即(ji)工業用電的頻(pin)率：弱電的頻(pin)率往(wang)往(wang)是高頻(pin)或特高頻(pin)，以(yi)KHz(千赫)、MHz(兆赫)計。

2、傳(chuan)輸方式不同

強電以輸電線路(lu)傳(chuan)輸，弱電的傳(chuan)輸有有線與無線之分。無線電則以電磁波傳(chuan)輸。

3、功率(lv)、電(dian)壓及電(dian)流大小不同

強電(dian)(dian)(dian)功率以(yi)(yi)(yi)千瓦(wa)、兆瓦(wa)計、電(dian)(dian)(dian)壓以(yi)(yi)(yi)伏、千伏計，電(dian)(dian)(dian)流以(yi)(yi)(yi)安(an)、千安(an)計；弱電(dian)(dian)(dian)功率以(yi)(yi)(yi)瓦(wa)、毫(hao)瓦(wa)計，電(dian)(dian)(dian)壓以(yi)(yi)(yi)伏、毫(hao)伏計，電(dian)(dian)(dian)流以(yi)(yi)(yi)毫(hao)安(an)、微安(an)計，因而其電(dian)(dian)(dian)路(lu)(lu)可以(yi)(yi)(yi)用印刷電(dian)(dian)(dian)路(lu)(lu)或(huo)集成電(dian)(dian)(dian)路(lu)(lu)構(gou)成。
