經常(chang)做項目施工的朋友會問(wen)到弱(ruo)電、強(qiang)(qiang)電有什么區別。弱(ruo)電指的是什么？強(qiang)(qiang)電指的是什么？今天華(hua)思特小編帶您了解下弱(ruo)電、強(qiang)(qiang)電。 

什么是弱電？

弱(ruo)電一般是指(zhi)直流(liu)電路或音頻(pin)(pin)、視頻(pin)(pin)線路、網絡(luo)線路、電話線路，直流(liu)電壓一般在36V以內。家用電(dian)(dian)器(qi)中(zhong)的(de)電(dian)(dian)話、電(dian)(dian)腦、電(dian)(dian)視機的(de)信(xin)號輸(shu)入(ru)（有(you)線電(dian)(dian)視線路）、音響(xiang)設備（輸(shu)出端線路）等用電(dian)(dian)器(qi)均為弱電(dian)(dian)電(dian)(dian)氣設備。 

什么是強電？

強電(dian)(dian)(dian)指(zhi)電(dian)(dian)(dian)工領域(yu)的電(dian)(dian)(dian)力部(bu)分。強電(dian)(dian)(dian)一般指(zhi)交流電(dian)(dian)(dian)電(dian)(dian)(dian)壓在(zai) 24V以上。如家(jia)(jia)庭中的(de)電燈、插座等，電壓在(zai) 110～220V。家(jia)(jia)用(yong)電氣中的(de)照明燈具、電冰箱、電視機、音(yin)響設備(bei)（輸(shu)入端）等用(yong)電器均為強電電氣設備(bei)。是相對于(yu)弱電而言的(de)。

一(yi)般來(lai)說強電(dian)(dian)的(de)處理對象(xiang)是(shi)能源（電(dian)(dian)力），其特點(dian)是(shi)電(dian)(dian)壓高、電(dian)(dian)流大、功率大、頻率低，主要考慮的(de)問題是(shi)減少損耗、提高效率。

弱電(dian)(dian)的處理(li)對象主要是(shi)信(xin)(xin)息(xi)(xi)，即信(xin)(xin)息(xi)(xi)的傳(chuan)(chuan)送(song)和控(kong)制，其特(te)點是(shi)電(dian)(dian)壓(ya)低(di)、電(dian)(dian)流小、功率小、頻(pin)率高，主要考慮的是(shi)信(xin)(xin)息(xi)(xi)傳(chuan)(chuan)送(song)的效果問題，如信(xin)(xin)息(xi)(xi)傳(chuan)(chuan)送(song)的保(bao)真(zhen)度、速度、廣度、可(ke)靠性。一般來說，弱電(dian)(dian)工(gong)程(cheng)(cheng)包括(kuo)電(dian)(dian)視工(gong)程(cheng)(cheng)、通信(xin)(xin)工(gong)程(cheng)(cheng)、消防工(gong)程(cheng)(cheng)、保(bao)安工(gong)程(cheng)(cheng)、影(ying)像(xiang)工(gong)程(cheng)(cheng)等(deng)等(deng)和為上述工(gong)程(cheng)(cheng)服務的綜合布(bu)線(xian)工(gong)程(cheng)(cheng)。 

弱電和強電的區別

1、交流(liu)頻率(lv)不(bu)同

強電的頻(pin)率一般是50Hz，稱"工頻(pin)"，意(yi)即工業(ye)用電的頻(pin)率(lv)：弱(ruo)電的頻(pin)率(lv)往(wang)往(wang)是高(gao)頻(pin)或特高(gao)頻(pin)，以KHz(千(qian)赫(he))、MHz(兆赫(he))計。

2、傳輸(shu)方式不(bu)同

強(qiang)電以輸電線(xian)路(lu)傳輸，弱電的傳輸有有線(xian)與無(wu)線(xian)之分。無(wu)線(xian)電則以電磁波傳輸。

3、功率、電壓及(ji)電流大小不同

強電(dian)(dian)(dian)功率(lv)(lv)以(yi)(yi)(yi)千(qian)瓦(wa)(wa)、兆(zhao)瓦(wa)(wa)計(ji)(ji)、電(dian)(dian)(dian)壓(ya)以(yi)(yi)(yi)伏(fu)(fu)、千(qian)伏(fu)(fu)計(ji)(ji)，電(dian)(dian)(dian)流以(yi)(yi)(yi)安(an)(an)(an)、千(qian)安(an)(an)(an)計(ji)(ji)；弱電(dian)(dian)(dian)功率(lv)(lv)以(yi)(yi)(yi)瓦(wa)(wa)、毫(hao)瓦(wa)(wa)計(ji)(ji)，電(dian)(dian)(dian)壓(ya)以(yi)(yi)(yi)伏(fu)(fu)、毫(hao)伏(fu)(fu)計(ji)(ji)，電(dian)(dian)(dian)流以(yi)(yi)(yi)毫(hao)安(an)(an)(an)、微(wei)安(an)(an)(an)計(ji)(ji)，因而(er)其電(dian)(dian)(dian)路(lu)可以(yi)(yi)(yi)用印刷電(dian)(dian)(dian)路(lu)或集成電(dian)(dian)(dian)路(lu)構成。
