【衛生間電器接地(di)】插(cha)座為什么要接地(di)線 怎樣判斷插(cha)座接地(di)線了

插座為什么要接地線：

作用1、地線起保護作用

電(dian)器(qi)設(she)備的(de)外殼通過插頭與(yu)地線(xian)相(xiang)連(lian)。插座接地線(xian)一旦漏電(dian)，電(dian)器(qi)設(she)備的(de)外殼就會帶電(dian)，但(dan)由(you)于地線(xian)的(de)作用(yong)，保證電(dian)器(qi)外殼與(yu)地線(xian)等電(dian)位，即(ji)對地電(dian)壓等于0，這樣就保證了電(dian)器(qi)使(shi)用(yong)者的(de)人身安全。

作用2、防漏電

帶有接地線的 孔插座可以將洗衣機，電(dian)(dian)(dian)(dian)(dian)冰箱的外殼接(jie)(jie)地(di)，在漏電(dian)(dian)(dian)(dian)(dian)的情(qing)況下，保護人不觸電(dian)(dian)(dian)(dian)(dian)。當用電(dian)(dian)(dian)(dian)(dian)器漏電(dian)(dian)(dian)(dian)(dian)時(shi)，電(dian)(dian)(dian)(dian)(dian)流直接(jie)(jie)通過地(di)線(xian)(xian)(xian)進入大(da)地(di)。防(fang)止人觸摸用電(dian)(dian)(dian)(dian)(dian)器是(shi)被(bei)電(dian)(dian)(dian)(dian)(dian)擊。地(di)線(xian)(xian)(xian)是(shi)直接(jie)(jie)與大(da)地(di)相通的，它與大(da)地(di)之間的電(dian)(dian)(dian)(dian)(dian)阻(zu)遠遠小于人身電(dian)(dian)(dian)(dian)(dian)阻(zu)，所以(yi)地(di)線(xian)(xian)(xian)是(shi)相當重(zhong)要的。你(ni)們家里的電(dian)(dian)(dian)(dian)(dian)腦的電(dian)(dian)(dian)(dian)(dian)源插座(zuo)有(you)沒(mei)有(you)連接(jie)(jie)著地(di)線(xian)(xian)(xian)？比較精(jing)密的電(dian)(dian)(dian)(dian)(dian)氣(qi)設備還可以(yi)釋放(fang)靜電(dian)(dian)(dian)(dian)(dian)，保護電(dian)(dian)(dian)(dian)(dian)氣(qi)設備及時(shi)導(dao)走電(dian)(dian)(dian)(dian)(dian)器上產生(sheng)的靜電(dian)(dian)(dian)(dian)(dian)或漏電(dian)(dian)(dian)(dian)(dian)。

怎樣判斷(duan)插座接地線了(le)：

首(shou)先把屋(wu)(wu)里(li)(li)總電(dian)源斷掉，找一(yi)根(gen)長線(xian)(xian)，一(yi)個手電(dian)燈(deng)泡(pao)(pao)(pao)一(yi)節大(da)電(dian)池，長線(xian)(xian)一(yi)頭(tou)插(cha)到其它插(cha)座(zuo)(zuo)(可以(yi)是(shi)本屋(wu)(wu)也可以(yi)是(shi)其它屋(wu)(wu)的插(cha)座(zuo)(zuo))地(di)線(xian)(xian)那眼里(li)(li)，一(yi)頭(tou)接電(dian)池再接燈(deng)泡(pao)(pao)(pao)，燈(deng)泡(pao)(pao)(pao)甩出來的另(ling)一(yi)頭(tou)插(cha)要(yao)測的插(cha)座(zuo)(zuo)地(di)線(xian)(xian)那眼里(li)(li)，利用(yong)屋(wu)(wu)里(li)(li)地(di)線(xian)(xian)做個回路，燈(deng)泡(pao)(pao)(pao)著就(jiu)沒問題(ti)，把所有的插(cha)座(zuo)(zuo)地(di)線(xian)(xian)眼都(dou)試試，證明屋(wu)(wu)里(li)(li)所有地(di)線(xian)(xian)都(dou)沒問題(ti)！

小編總結：插座里的地線經專線通往大地，插頭上較長的那只腳與用電器的金屬外殼連接。當用電器出現漏電故障時或用電器使用時使外殼帶上正常的感應電時，這些電會通過地線被導入大地，以避免人員觸電，起到保護人身安全的作用。據調查統計，所有的因電熱水器、冰箱等(deng)用(yong)電器漏(lou)電造成的觸(chu)電死亡事(shi)故，用(yong)電器全部未(wei)接地(di)線或(huo)地(di)線接地(di)不良(liang)。
