一、如何辨別(bie)強弱(ruo)電？

1.強電(dian)(dian)(dian)傳導(dao)的是(shi)電(dian)(dian)(dian)能，而弱電(dian)(dian)(dian)傳導(dao)的是(shi)信(xin)號(hao)。如電(dian)(dian)(dian)動剃須(xu)刀、手電(dian)(dian)(dian)筒(tong)等(deng)傳導(dao)的就是(shi)電(dian)(dian)(dian)能，屬于(yu)強電(dian)(dian)(dian)類(lei)，若僅因其(qi)電(dian)(dian)(dian)源為(wei)(wei)兩節(jie)干電(dian)(dian)(dian)池、電(dian)(dian)(dian)壓較小，就將其(qi)判定(ding)為(wei)(wei)弱電(dian)(dian)(dian)是(shi)非常不(bu)正(zheng)確(que)的。

2.高壓(ya)包(bao)括強(qiang)電(dian)(dian)(dian)(dian)，強(qiang)電(dian)(dian)(dian)(dian)不一定(ding)屬于高壓(ya);低壓(ya)包(bao)括弱電(dian)(dian)(dian)(dian)，弱電(dian)(dian)(dian)(dian)一定(ding)屬于低壓(ya);低壓(ya)不一定(ding)就(jiu)是強(qiang)電(dian)(dian)(dian)(dian)，強(qiang)電(dian)(dian)(dian)(dian)不一定(ding)就(jiu)是低壓(ya)。

3.強(qiang)電(dian)(dian)(dian)弱電(dian)(dian)(dian)怎么區別(bie)的(de)基礎要素是電(dian)(dian)(dian)壓。強(qiang)電(dian)(dian)(dian)具有較高的(de)電(dian)(dian)(dian)壓，通常大于(yu)等于(yu)220V;處于(yu)220V以(yi)下(xia)電(dian)(dian)(dian)壓的(de)則是弱電(dian)(dian)(dian)。大元電(dian)(dian)(dian)線電(dian)(dian)(dian)纜小(xiao)編提醒你，并(bing)不(bu)是小(xiao)于(yu)220v就是安全的(de)哦，請(qing)一定一定不(bu)能掉(diao)以(yi)輕心(xin)哦！

在購(gou)買(mai)電(dian)線的時候，相信大家都碰到(dao)強(qiang)電(dian)和弱(ruo)電(dian)這(zhe)2個概(gai)念，那么(me)它(ta)們的區別(bie)大家知道嗎(ma)?今天大元電(dian)線電(dian)纜小編一(yi)分(fen)鐘教你辨別(bie)它(ta)們的區別(bie)，因(yin)為(wei)高壓而(er)(er)稱(cheng)之(zhi)為(wei)強(qiang)電(dian)，因(yin)為(wei)低(di)壓而(er)(er)稱(cheng)之(zhi)為(wei)弱(ruo)電(dian)嗎(ma)?顯然不是的!

二、強電(dian)和弱電(dian)的區別(bie)

(1)交(jiao)流頻率不同

強電的頻(pin)(pin)率一般是50Hz，稱“工頻(pin)(pin)”，意即工業用(yong)電的頻(pin)(pin)率：弱電的頻(pin)(pin)率往往是高頻(pin)(pin)或特高頻(pin)(pin)，以KHz(千赫)、MHz(兆赫)計。

(2)傳輸方式不同

強電以輸電線(xian)(xian)路傳(chuan)輸，弱電的傳(chuan)輸有有線(xian)(xian)與無線(xian)(xian)之分。無線(xian)(xian)電則以電磁波傳(chuan)輸。

(3)功率(lv)、電(dian)壓及電(dian)流大小不同(tong)

強電(dian)(dian)功(gong)率(lv)以(yi)(yi)千(qian)(qian)(qian)瓦(wa)、兆瓦(wa)計(ji)(ji)(ji)、電(dian)(dian)壓以(yi)(yi)伏、千(qian)(qian)(qian)伏計(ji)(ji)(ji)，電(dian)(dian)流以(yi)(yi)安、千(qian)(qian)(qian)安計(ji)(ji)(ji);弱電(dian)(dian)功(gong)率(lv)以(yi)(yi)瓦(wa)、毫(hao)瓦(wa)計(ji)(ji)(ji)，電(dian)(dian)壓以(yi)(yi)伏、毫(hao)伏計(ji)(ji)(ji)，電(dian)(dian)流以(yi)(yi)毫(hao)安、微安計(ji)(ji)(ji)，因而(er)其(qi)電(dian)(dian)路(lu)(lu)可以(yi)(yi)用印(yin)刷電(dian)(dian)路(lu)(lu)或集成電(dian)(dian)路(lu)(lu)構成。

三、什么(me)是弱(ruo)電：

弱電(dian)一(yi)(yi)般指直流電(dian)路或音頻、視頻線路、網絡線路、電(dian)話線路，直流電(dian)壓(ya)一(yi)(yi)般在36V以(yi)內。

什么是強(qiang)電：

強電(dian)指電(dian)工領域的電(dian)力(li)部分。是相對(dui)于弱電(dian)而言的。
