今天金環宇電線電纜帶大家了解下什么是弱電，什么是強電？
一、什(shen)么是弱電？
弱(ruo)電(dian)(dian)(dian)一(yi)般是指直流電(dian)(dian)(dian)路(lu)或音(yin)頻、視(shi)頻線路(lu)、網絡線路(lu)、電(dian)(dian)(dian)話線路(lu)，直流電(dian)(dian)(dian)壓一(yi)般在(zai)32V以內。家用電(dian)(dian)(dian)氣中的(de)電(dian)(dian)(dian)話、電(dian)(dian)(dian)腦、電(dian)(dian)(dian)視(shi)機的(de)信號輸(shu)(shu)入（有(you)線電(dian)(dian)(dian)視(shi)線路(lu)）、音(yin)響設(she)備（輸(shu)(shu)出端線路(lu)）等用電(dian)(dian)(dian)器均為弱(ruo)電(dian)(dian)(dian)電(dian)(dian)(dian)氣設(she)備。
二(er)、什么是強電？
強電(dian)(dian)指電(dian)(dian)工領域的(de)電(dian)(dian)力部(bu)分。特(te)點是功率大(da)、電(dian)(dian)流大(da)、頻率低，主(zhu)要考慮損耗小、效率高的(de)問題。和弱(ruo)電(dian)(dian)的(de)關系很(hen)密(mi)切(qie)，與“弱(ruo)電(dian)(dian)”相對。
三、二者有何區別(bie)
強(qiang)電和弱(ruo)電主要區別是(shi)用(yong)途(tu)的不同(tong)。強(qiang)電是(shi)用(yong)作(zuo)一種(zhong)動力能源，弱(ruo)電是(shi)用(yong)于信(xin)息傳(chuan)遞。
強電(dian)和弱電(dian)從概念(nian)上(shang)講，一般是容易區別(bie)的(de)(de)，主要區別(bie)是用(yong)途的(de)(de)不同。強電(dian)是用(yong)作一種動力能源，弱電(dian)是用(yong)于(yu)信息(xi)傳遞。家庭電(dian)路分為(wei)(wei)強電(dian)和弱電(dian)。在電(dian)力系統中，36V以(yi)下的(de)(de)電(dian)壓(ya)(ya)(ya)稱為(wei)(wei)安全電(dian)壓(ya)(ya)(ya)，1kV以(yi)下的(de)(de)電(dian)壓(ya)(ya)(ya)稱為(wei)(wei)低(di)壓(ya)(ya)(ya)，1kV以(yi)上(shang)的(de)(de)電(dian)壓(ya)(ya)(ya)稱為(wei)(wei)高壓(ya)(ya)(ya)，直接供電(dian)給用(yong)戶(hu)的(de)(de)線路稱為(wei)(wei)配電(dian)線路，如用(yong)戶(hu)電(dian)壓(ya)(ya)(ya)為(wei)(wei)380/220V，則稱為(wei)(wei)低(di)壓(ya)(ya)(ya)配電(dian)線路，也就是家庭裝(zhuang)修中所說的(de)(de)強電(dian)。
強(qiang)電(dian)(dian)(dian)(dian)(dian)(dian)與弱(ruo)(ruo)電(dian)(dian)(dian)(dian)(dian)(dian)是(shi)(shi)相(xiang)對的概(gai)念，從概(gai)念上講，主(zhu)(zhu)要區(qu)(qu)別是(shi)(shi)用途的不同，而(er)不能單純的以(yi)電(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)大小(xiao)來界定(ding)(ding)(ding)兩(liang)者關系(如果(guo)非要指定(ding)(ding)(ding)用電(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)區(qu)(qu)分(fen)(fen)的話，那(nei)就把36V(人體(ti)安全(quan)(quan)電(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)(ya))以(yi)上劃定(ding)(ding)(ding)為強(qiang)電(dian)(dian)(dian)(dian)(dian)(dian), 36V(人體(ti)安全(quan)(quan)電(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)(ya))以(yi)下為劃定(ding)(ding)(ding)為弱(ruo)(ruo)電(dian)(dian)(dian)(dian)(dian)(dian)。) ，兩(liang)者既有聯系又有區(qu)(qu)別，一般區(qu)(qu)分(fen)(fen)原則是(shi)(shi)：強(qiang)電(dian)(dian)(dian)(dian)(dian)(dian)的處(chu)理對象是(shi)(shi)能源（電(dian)(dian)(dian)(dian)(dian)(dian)力），其(qi)(qi)特點是(shi)(shi)電(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)高(gao)、電(dian)(dian)(dian)(dian)(dian)(dian)流大、功率(lv)大、頻(pin)率(lv)低(di)(di)，主(zhu)(zhu)要考慮的問題是(shi)(shi)減少(shao)損耗、提高(gao)效(xiao)率(lv)，弱(ruo)(ruo)電(dian)(dian)(dian)(dian)(dian)(dian)的處(chu)理對象主(zhu)(zhu)要是(shi)(shi)信(xin)息(xi)，即信(xin)息(xi)的傳(chuan)(chuan)送(song)和控制，其(qi)(qi)特點是(shi)(shi)電(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)低(di)(di)、電(dian)(dian)(dian)(dian)(dian)(dian)流小(xiao)、功率(lv)小(xiao)、頻(pin)率(lv)高(gao)，主(zhu)(zhu)要考慮的是(shi)(shi)信(xin)息(xi)傳(chuan)(chuan)送(song)的效(xiao)果(guo)問題，如信(xin)息(xi)傳(chuan)(chuan)送(song)的保真度、速度、廣(guang)度、可(ke)靠性。
